ÈOperating-/Settings DiagramContinuous displayFunction DescriptionOperating modes Operating modes are selected using the MODE menu (depending upon identity code, someoperating modes may be absent)..“Analogue” operating mode: (Identity code, control variant: analogue current)The stroke rate is controlled via an analogue electrical signal via the “external control” terminal.Signal processing is pre-selected at the controller.“Manual” operating mode: (Identity code, control variant: manual, standard function)The stroke rate is controlled manually via the controller.“Contact” operating mode: (Identity code, control variant: external 1:1 / external with pulsecontrol)This operating mode offers the opportunity to make fine adjustments with small increase/decrease factors. Dosing can be activated by a pulse via the “external control” terminal or by asemiconductor element. With the “pulse control” option it is possible to pre-set a feed quantity(batch) or number of strokes (factor 0.01 to 99.99) via the control unit.“Batch” operating function: (identity code, control variant, external 1:1 / external with pulsecontrol)This operating mode offers the option of working with larger transfer factors (up to 65535).Metering can be triggered by pressing the P key or a pulse from the “external control” terminalvia a contact or semiconductor element. A batching quantity or number of strokes can be pre-selected via the control unit.Functions The following functions can be selected using the SET menu:“Calibrate” function:The gamma/ L can be operated in all operating modes including in calibrating mode. Thecorresponding continuous displays can show the actual feed quantity or the feed rate.Calibration is maintained within the stroke frequency range 0 - 180 strokes/ min. Calibration isalso maintained when a stroke frequency is altered up to ± 10 %.“Pressure level” function:It is possible to set different pressure levels.“Auxiliary frequency” function:It is possible to set a stroke rate in the SET menu, which may be activated via the “externalcontrol” terminal. This auxiliary frequency overrides all other pre-set stroke rate frequencies.“Flow” function:Stops the gamma/ L when the flow is insufficient. In the SET menu, the number of failed strokesis entered after which the pump will be turned off.The following functions are available as standard:“Float switch” function:Information on the liquid level in the feed chemical container is transmitted to the gamma/ L.This option requires the installation of a 2-stage float switch. This is connected to the “floatswitch” terminal.“Pause” function:The gamma/ L can be stopped by remote control via the “external control” terminal. The “pau-se” function operates only via the “external control” terminal.The following functions are activated by keystrokes:“Stop” function:The gamma/ L can be stopped by pressing the STOP/START key without disconnecting fromthe mains power supply.Function Description“Prime” function:Priming (short term feed at maximum frequency) is activated by pressing both arrow keys at thesame time.Optional relay The gamma/ L has two connection options.“Fault indicating relay” option:In the event of fault signals, warning signals or float switch activation signals, connects anelectrical circuit to trigger alarm sirens etc. The relay is retrofitted via an aperture in the powerend.“Fault indicating and pacing relay” option:Along with the fault indicating relay, the pacing relay produces an electrical impulse for everystroke. The relay is retrofitted via an aperture in the power end.Function and errorindicators The operating and error status is shown via the three LEDs and the “error” indicator on the LCD (see also section 12):LCD indicator If a fault occurs “error” will appear along with an additional fault warning.LED indicator Operating indicator (green)This indicator is lit as long as the gamma/ L is operating correctly.Warning indicator (yellow)This warning light appears if the gamma/ L electronics detect a situation that could lead to afault, e.g. “liquid levels low 1st stage”.Warning indicator (red)This warning light appears if a fault occurs, e.g. “liquid levels low 2nd stage”.Hierarchy of operating modes, functions and fault statusesThe different operating modes, functions and fault statuses each have a differing effect onwhether and how the gamma/ L functions. These effects are given below:1.Prime2.Fault, stop, pause3.Auxiliary frequency4.Manual, analogue, contact, batchto:1.“Prime” can be activated in any pump status (as long as it is operable)2.“Fault”, “stop” and “pause” stop all system parts up to “prime”.3.The stroke rate of the “auxiliary frequency” always overrides the existing operating strokerate.Commissioning / Operating8.2Diagrams for setting feed capacityGeneralS Open out the page showing the diagram of your pump type (see appendix).S Calculate the correction factor. Mark the operating pressure for your application in the dia-gram “correction factor depending upon operating pressure”.S Trace a line from this value vertically up to the curve and then horizontally left. Read off thecorrection factor.S Divide the required feed rate by the correction factor determined as above. Mark this value(l/h) on the “l/h” axis in the diagram “feed rate depending upon stroke length and strokerate”.S Trace a line horizontally from this value to the left. Trace a line from the intersection with thestraight line for the adjustable stroke frequencies vertically downwards to the “strokelength” axis.S Set the gamma/ L to one of the stroke frequencies determined in this way, and thecorresponding stroke length.The measurements for determining the feed rate for the following diagrams were carried outusing water and the correction factor was determined at a 70 % stroke length. Distribution ofthe feed rate across all material versions: -5 to +15 %.9OperatingThis section describes all operating options available to you when the gamma/ L is incontinuous display mode (no P key symbol in the LCD display).GUIDELINE•Open out the fold-out page following the title page fully! There you will find theoverviews “control elements and key functions” and “operating settings dia-gram”.•Look at the overview “continuous displays”. This page shows you which displaysare available in which operating mode, and which values are directly alterable inthe corresponding continuous displays.9.1Manual operationSet stroke length Stroke length is continually adjustable within a range of 0 - 100 %. The recommended strokelength range, which will practically guarantee technical reproducibility, is 30 - 100 % (SEK type:50 - 100 %).The following operating options are available via the different keys (see also figure on the nextpage):Stop/Start gamma/ L To stop gamma/ L: press STOP/START key.To start gamma/ L: press STOP/START key.Start batch Press the P key briefly in “batch” operating mode.Load factory settings Press the P key for 15 s to load factory calibration settings!Current settings will be deleted.Change to settings mode WeIf you press the P key for 2 s in any continuous display the gamma/ L will change to settingsmode (see section 7).If CODE 1 is set, the code must be entered after pressing the P key.Check adjustable values Each time you press the i key you will see a different continuous display. The number ofcontinuous displays depends upon the identity code, the selected operating mode and theconnected accessories.Change directlyalterable values To change a value (see below) directly in the corresponding continuous display, press one of thearrow keys until “set” appears in the LCD display. The delay has been programmed in to preventinadvertent changing of values.If CODE 2 has been set, this code must be entered after pressing the arrow key.Directly alterable values are as follows:。

类普鲁士蓝的制备及其活化PMS降解双酚S

化工进展Chemical Industry and Engineering Progress2023 年第 42 卷第 12 期类普鲁士蓝的制备及其活化PMS 降解双酚S杨有威1，2，3，曾亦婷1，2，郭昌胜3，罗玉霞1，2，高艳1，2，王春英1，2（1 矿冶环境污染防控江西省重点实验室，江西赣州 341000；2 江西理工大学资源与环境工程学院, 江西赣州341000；3 中国环境科学研究院环境基准与风险评估国家重点实验室, 北京 100012）摘要：通过简单共沉淀法合成了类普鲁士蓝化合物（CoFe-PBA ），用于活化过一硫酸盐（PMS ）降解有机污染物双酚S （BPS ）。

使用扫描电镜、X 射线衍射、X 射线光电子能谱等手段对CoFe-PBA 进行表征，结果表明CoFe-PBA 由紧密结合的Co 3[Fe(CN)6]2构成，为纳米级，表面均匀分布着C 、Fe 、Co 、O 元素，具有丰富的活性位点。

催化剂投加量300mg/L 、PMS 投加量400mg/L 、pH=5.89条件下，CoFe-PBA/PMS 降解体系40min 内去除73.77%的BPS ，对酸性和共存离子（SO 42−、NO 3−和Cl −）敏感，碱性环境能促进PMS 快速活化，重复实验显示该体系具有良好稳定性，使用4次后仅下降26.70%，活化性能优于其他材料。

机理分析表明，CoFe-PBA 与PMS 相互作用，作用过程中改变了金属位点价态，发生电子转移，产生各种活性物质降解BPS ，其主要作用活性物种为1O 2；产物分析表明，在CoFe-PBA 活化PMS 系统中，BPS 可历经三种路径最终转化为开环产物及CO 2和H 2O 。

本研究通过低耗能、低成本、快速简易的方法制备CoFe-PBA ，可为活化PMS 绿色降解BPS 提供思路。

CoFe-PBA showed high activity on the removal of bisphenol S from activated PMS. Scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy were used to characterize CoFe-PBA. The results showed that CoFe-PBA was composed of Co 3[Fe(CN)6]2, which was in nanometer scale. The surface was evenly distributed with C, Fe, Co, O elements, with abundant active sites.

This electrical equipment, within the operational parameters specified by the manufacturer, ensures a very high level of protection that includes rare faults related to the equipment or two faults occurring independently of each other.NOTE 1 A malfunction may result from a failure of the component parts of the electrical equipment or from anticipated externally applied influences. Two independent malfunctions which may occur more frequently and which, separately, would not create an ignition hazard but which, in combination, could create a potential ignition hazard, should be regarded as occurring together to form a rare fault.NOTE 2 This electrical equipment is intended for use in zone 0 hazardous areas, in which explosive gas atmospheres caused by mixtures of air and gases, vapours or mists under normal atmospheric conditions are present continuously, for long periods or frequently.This standard also applies to equipment mounted across a boundary where different protection levels may be required.EXAMPLE: In the wall of a storage vessel containing zone 0 with an ambient defined as zone 1.This standard also applies to equipment installed in an area requiring a lower protection level, but electrically connected to equipment with equipment protection level (EPL) Ga (associated apparatus).This standard supplements the general requirements in IEC 60079-0 and the requirements of the standardized types of protection, in accordance with the IEC 60079 series, to adapt the level of safety provided by those standards in order to provide EPL Ga.NOTE 3 In designing equipment for operation in explosive gas atmospheres under conditions other than the atmospheric conditions given in IEC 60079-0, this standard may be used as a guide. However, additional testing is recommended related specifically to the intended conditions of use. This is particularly important when the types of protection ‘Flameproof enclosures’ (IEC 60079-1) and ‘Intrinsic safety’ (IEC 60079-11) are applied.NOTE 4 The classification of hazardous areas in zones is defined in IEC 60079-10.NOTE 5 There may be other non-electrical sources of ignition (for example ultrasonic, optical or ionizing radiation) that are not addressed by this standard; these should also be taken into consideration (see, for example, EN 1127-1). NOTE 6This concept provides equipment protection level (EPL) Ga.

Consideration should also be given to minimize the effect of transient fault currents in the potential equalization network by the use of electrical protection equipment such as sensitive earth leakage monitors.4.2.2 Intrinsic safety as a sole means of protectionIntrinsically safe electrical equipment providing EPL Ga and intrinsically safe electrical circuits of associated apparatus entering an area requiring EPL Ga shall comply with the requirements of IEC 60079-11, intrinsic safety “ia”.NOTE Intrinsic safety “ib” in accordance with IEC 60079-11 may be considered as one of two independent means of protection according to 4.2.4.4.2.3 Encapsulation as a sole means of protectionElectrical equipment which is protected by encapsulation providing EPL Ga shall comply with the requirements of IEC 60079-18, encapsulation “ma”.NOTE Encapsulation “mb” in accordance with IEC 60079-18 may be considered as one of two independent means of protection according to 4.2.4.4.2.4 Application of two independent types of protection providing EPL GbElectrical equipment shall comply with the requirements of two independent types of protection that provide EPL Gb. If one type of protection fails, the other type of protection shall continue to function. The independent types of protection shall not have a common mode of failure, except as specified in this clause.An example of a common mode failure is if an Ex “d” enclosure with arcing contacts inside it is used inside an Ex “e” enclosure. If the Ex “d” enclosure is compromised, then arcing inside the enclosure will also compromise the Ex “e” enclosure.NOTE Combined types of protection providing EPL Gb should depend on different physical protection principles. For example the combination of Ex “d” and Ex “q” both depend on the avoidance of flame propagation and may not be useful in combination. In practice, some combinations may not be useful, for example the combination of oil and powder filling.Where combined types of protection are used, it shall be possible for each type of protection to be tested individually (see 5.1).Both types of protection shall be assessed using the most arduous fault condition of the other type of protection. When combining intrinsic safety, type of protection “ib”, with other types of protection, the second type of protection shall be assessed, with the most arduous fault condition applied to the intrinsically safe circuit.When using two types of protection, which rely both on the same parameter (for example, the creepage distance combining Ex “ib” with Ex “e”), the most stringent requirement of both types of protection shall be applied.IS/IEC 60079-26 : 2006If two types of protection are combined which both rely on the enclosure, one of the following shall be met:a) if two enclosures are used (one totally enclosed within the other), each enclosure shallcomply with the requirements of the respective type of protection; orb) if only one enclosure is used, the enclosure and the cable glands shall meet the impact testrequirements of 26.4.2 of IEC 60079-0, using the group I values.Examples of combinations of two independent types of protection are as follows:– inductive transmitters (for example proximity switches, electrical position sensors) with intrinsic safety “ib” enclosed by encapsulation “mb”.

These components may be incorporated in a flameproof enclosure “d”; – measuring transducers with intrinsic safety “ib” and a flameproof enclosure “d”;– equipment with electrical circuits of intrinsic safety “ib”, additionally protected by a powder filling “q”;– electromagnetic valves with encapsulation “mb”, enclosed by a flameproof enclosure “d”;– increased safety “e”, with pressurized equipment “px”.4.2.5 Application of a type of protection providing EPL Gb and a separation element 4.2.5.1 GeneralEquipment which is mounted through or forming part of the boundary wall to an area requiring EPL Ga and containing electrical circuits which do not comply with protection level Ga shall comply at least with one of the types of protection providing EPL Gb. Additionally, they shall contain a mechanical separation element as part of the equipment to seal off the electrical circuits of the equipment from the area requiring EPL Ga.If the type of protection fails, the separation element shalla) prevent flame propagation through the equipment into the area requiring EPL Ga,b) maintain its safety characteristics,c) not be heated above the temperature class of the equipment.Separation elements consist of a partition wall, possibly combined with a flameproof joint or an air gap with natural ventilation.4.2.5.2 PartitionwallsPartition walls shall be constructed of eithera) corrosion-resistant metals, glass or ceramics, which are specified in the manufacturer’sdocumentation; orb) other materials as long as the same level of safety can be demonstrated. In this case, X-marking or an advisory marking in accordance with 29.2 of IEC 60079-0 shall be applied and the certificate shall clearly specify the material and its thermal and mechanical properties to enable the user to confirm the suitability for the particular application.If the wall thickness is less than 1 mm, the equipment shall be marked with an “X” or an advisory marking according to 29.2 of IEC 60079-0 with a special condition for safe use that the material shall not be subject to environmental conditions which might adversely affect the partition wall.

通过接种少量Anammox 污泥和逐步提高氨氮浓度的操作方式，在连续运行58d 后，系统成功启动Anammox 反应，此时的总氮和COD 去除率稳定在97%和98%以上。

物料衡算显示，Anammox 反应途径对氮的去除贡献逐渐增加，硝酸盐异化还原（DNRA ）耦合Anammox 和反硝化共同促进了系统的同步脱氮除碳。

对微生物群落分析发现，Candidatus Kuenenia 相对丰度由0.27%快速升高至35.87%，DNRA 菌（Ignavibacterium 、Thermogutta ）及反硝化菌（Azospira 、Gp 3）在体系内共存。

通过基因注释法，检测出了Anammox 、DNRA 、硝酸盐还原及亚硝酸盐还原关键基因。

运行过程中，颗粒污泥颜色变红且粒径增大；胞外聚合物（EPS ）分析表明多糖（PS ）和蛋白质（PN ）含量增加而PN/PS 下降；三维荧光光谱发现腐殖酸类物质增多。

研究结果为高浓度有机含氮废水高效处理提供了一种新的工艺途径。

The adsorption behaviors of Cu2+ andPb2+ in aqueous solutions on two persimmon biosorbents were investigated. The effects of solution pH, solid-liquid ratio, temperature, adsorption time and metal ion concentration were considered. The results show that the adsorption process of SPP and HPP can be well described by pseudo-second order kinetic equation. The fitting effect of equilibrium isotherms follows Langmuir equation better than that of the Freundlich equation. The maximum adsorption capacities of Cu2+ and Pb2+ on SPP are 61.47 mg/g and 207.90 Mg/g, respectively. And the maximum adsorption capacities of Cu2+ and Pb2+ on HPP are 64.0 mg/g and 220.8 mg/g, respectively.

探讨改性偶氮二甲酰胺在聚氨酯发泡中的可行性。

方法通过改变体系中改性偶氮二甲酰胺的用量，探讨改性偶氮二甲酰胺对聚醚发泡体系黏度、聚氨酯泡沫力学性能和导热系数的影响。

结果发泡剂的加入能显著降低聚醚体系的黏度，提高发泡物料的流动性，随着改性AC用量的增加，体系黏度逐渐增加，当改性AC的添加量为0.3 g时，体系黏度最低为2 080 mPaꞏs。

当改性AC用量为0.75 g时，聚氨酯泡沫的表观密度为78.65 kg/m3，压缩强度为539.35 kPa，改性AC的加入使得聚氨酯泡沫的导热系数增高，导热系数为0.023 51 W/mK。

结论改性AC的加入能显著提高硬质聚氨酯泡沫的压缩强度，相比纯水发泡，二者复合发泡性能更优异，可以作为无卤素发泡剂应用于聚氨酯发泡。

By changing the amount of modified azodicarbonamide in the system, the effects of modified azodicarbonamide on the viscosity, mechan-ical properties and thermal conductivity of the polyether foaming system were investigated. The results showed that the addition of the foaming agent could significantly reduce the viscosity of the polyether system and improve the fluidity of the foamed material, and the viscosity of the system gradually increased with the increase of the amount of modified AC, and the lowest viscosity of the system was 2 080 when the amount of modified AC was 0.3 g. When the amount of mod-ified AC was 0.75 g, the apparent density of polyurethane foam was 78.65 kg/m3, the compression strength was 539.35 kPa, and the addition of modified AC increased the thermal conductivity of polyurethane foam, which was 0.023 51 W mK-1. The addition of modified AC can obviously improve the compressive strength of rigid polyurethane foam. Com-pared with pure water foaming, the compound foaming performance of the two is superior and can be applied to polyure-thane foaming as a halogen-free foaming agent.KEY WORDS: modified azodicarbonamide; halogen-free rigid polyurethane; compressive strength; foaming agent收稿日期：2023-06-02·284·包装工程2023年10月在21世纪的聚氨酯工业中，硬质聚氨酯泡沫（RPUF）[1]被广泛用作建筑外墙保温、包装、冷链以及管道外层的保温抗压材料。

Product Data SheetTrigonox B-C30Di-tert-butyl peroxide, 30% solution in isododecaneTrigonox® B-C30 is an efficient initiator (30% active ingredient in odorless mineral spirits) for the production of Low Density Polyethylene (LDPE). It is used for both tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range CAS number110-05-4EINECS/ELINCS No.203-733-6TSCA statuslisted on inventoryMolecular weight146.2Active oxygen contentperoxide10.94%Concentration3.17-3.39%SpecificationsAppearance Clear liquidAssay29.0-31.0 %Color≤ 30 Pt-CoHydroperoxides as TBHP≤ 0.03 %CharacteristicsDensity, -10 °C0.810 g/cm³ApplicationsTrigonox® B-C30 is an efficient initiator for the production of Low Density Polyethylene (LDPE). It is used both for tubular and autoclave processes. In most cases a combination with other peroxides is used to ensure a broad reactivity range.Half-life dataThe reactivity of an organic peroxide is usually given by its half-life (t1/2) at various temperatures. For Trigonox® B-C30 in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:0.1 hr at 164°C1 hr at 141°C10 hr at 121°CFormula 1kd = A·e-Ea/RTFormula 2t½ = (ln2)/kdEa153.46 kJ/moleA 4.20E+15 s-1R8.3142 J/mole·KT(273.15+°C) KThermal stabilityOrganic peroxides are thermally unstable substances which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition may occur with a substance in the packaging as used for transport is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.Method The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria - United Nations, NewYork and Geneva).StorageDue to the relatively unstable nature of organic peroxides, a loss of quality will occur over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.Ts max.40°CNote When stored according to these recommended storage conditions, Trigonox® B-C30 will remain within the Nouryon specifications for a period of at least 3 monthsafter delivery.Packaging and transportThe standard packaging is a 1000 l composite Intermediate Bulk Container (IBC). Delivery in a 20 m3 Nouryon tank container is also possible in a number of countries. Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Nouryon representative. Trigonox® B-C30 is classified as Organic peroxide type F; liquid, Division 5. 2; UN 3109.Safety and handlingKeep containers tightly closed. Store and handle Trigonox® B-C30 in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g. amines), acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps).
