（第三段）4. Air currents move water vapor around the
globe,cloud particles collide,grow,and fall out of the sky as precipitation.Some precipitation falls as snow or hail,sleet,and can accumulate as ice caps and glaciers,which can store frozen water for thousands of years.Most water falls back into the oceans or onto land as rain,where the water flows over the ground as surface runoff.

Unit 1 Water and Hydrological Cycle
toxic pathogenic microorganism congregate metropolitan a. a. n. v. a. 有毒的，中毒的 致病的，病愿的 微生物 聚集 大城市的
n. a.
污染物质 水文学的
designate nutrient medium microbial algae
vt. n. n. a. n.（alga的复数）
表示，称为 养分，养科 介质，培养基 微生物的，细菌的 藻类，海藻

Source of water
¡ [2] All water comes in the form ofprecipitation.
The heat of the sun evaporates water from the oceans, seas, rivers and lakes. The heat also evaporates water from the ground and from plants and animals. Water vapor is formed. This rises and forms clouds in the air. When the clouds come near a mountain, they are forced to rise.
fall a prey to=suffer from

给水处理污泥工艺的选择
1
Historically, settled coagulation wastes and backwash waters had been disposed of without treatment. 过去，沉淀的混凝废弃物与反冲水是不经处理而直接排放的。 The practice was justified on the basis that the returned material had originally been present in the river or lake. 基于这些返回的物质是河流与湖泊中原本就有的，这种做法 曾经被认为正确的。
Emphasis is placed on preventing magnesium hydroxide precipitation, since it inhibits dewaterability and processing for recovery of lime. 应当强调的是，由于氢氧化镁抑制脱水性能和 回收石灰的处理，要防止形成氢氧化镁沉淀。

第一单元水中的主要污染物Water briefiy水因含有过量的气态，液态和固态成分而被认为受到污染。
可能污染水的物质是列举不完的这里简要的讨论一些主要的污染物。
有机污染物Organic origin有机污染物是由来自农村及城市的生活污水和以动物和植物为原料的工业废水而产生的。
Although wastes虽然生活污水是可降解有机污染物最广泛的来源，但是工业也可以产生大约与其等量的此种污染物。
The waters最大的工业有机废物的制造者是食品和纸浆造纸工业，这些工业有众多生产厂家，其中许多厂家都将大量的有机废物排入水体。
One people一个甜菜加工厂在它主要的生产期内所产生的有机废物相当于一个拥有五十万人口的城市所排放的生活污水量。
The problem有机废物被细菌分解消耗水中的氧，进而产生严重的问题。
Since environment因为鱼类和水生物依靠溶解氧，而好氧有机物却破坏了这种水生环境。
When result当这种废物消耗过量的氧时，就会造成严重的腐化性污染状态。
活性物质Living disease活性物质能污染水的包括细菌，病毒和可以引起疾病的其它微生物。
These slaughter这些有机物可能通过生活污水或某些种类的工业废水进入水体，尤其是那些马制革或动物屠宰有关的工业而进入水体中。
Since environment虽然在世界上大多数发达国家引起伤寒和霍乱的细菌得到了有效的控制，但是在很多不发达国家仍然存在危险。
When result可能引起肠道或其它传染病的难以消灭的病毒会造成持续的水污染问题。
植物营养素Plant water刺激植物生长的植物营养素也是水的一种主要污染物。
The present在植物营养素当中两种最基本水污染元素是氮和磷，并且也存在其他的微量元素。
These nitrates这些元素在自然水中存在很少，绝大部分是由生活污水，某种工业污废水，土地施肥后的排水和含硝酸盐量高的地下层提供的。

Unit 1好氧生物降解追溯到上个世纪早期，生物污水处理法的主要目的是(i)去除从城市或工厂点排放的污水中的有机组分和化合物以防止多余溶解氧的消耗，(ii)去除胶体和悬浮性固体来避免污水中固体积聚和有害状况下的产物，(iii)降低释放到污水中的致病有机体的浓度。
美国环保署在1972年制定的二级处理管理标准仍有效，该标准主要致力于生化需氧量和悬浮性总固体的去除，并分别要求85%的去除率。
大多数的处理应用涉及有机组分和化合物的去除，因为它们在污水中大量存在，有机组分能够被量化表征可生物降解的可溶性的化学需氧量和生化需氧量。
过程描述生化需氧量的去除可以通过一些好氧悬浮生长或接触生长处理过程来完成。
这两个过程都要求污水和异养有机体有充足的接触时间，足够的氧气和营养。
在开始的有机原料摄取阶段，多于半数的被氧化，剩余的作为新的生物量被吸收，可能通过内源呼吸被进一步氧化。
对于悬浮生长和接触生长过程，每天多余产生的生物量被去除和处理来维持正常的操作和表现。
生物量从处理的出水中通过重力法分离出来，还有更多利用膜分离的近期设计正在被应用。
微生物很多种用来去除有机物的微生物体在好氧悬浮生长和接触生长处理工艺中被发现。
该过程中被发现的好氧异养菌能够生产导致生物絮体（或为接触生长过程而生的生物膜）形成的菌胶团，它可以从相对低浓度的细菌和悬浮固体的处理液中通过重力沉降法分离。
原生动物在好氧生物处理过程中亦扮演着重要的角色。
通过消耗游离细菌和胶体颗粒，原生动物帮助出水变得澄清。
原生动物比起好氧异养细菌要求更长的固体停留时间，最适宜溶解氧浓度大于 1.0mg/l，并且它对毒物很敏感，所以它们的出现对于稳定过程操作是很好的指示剂。
由于他们的尺寸，原生动物可以很容易在100-200放大倍数的光学显微镜下被观察到。
轮虫也可以被在活性污泥和生物膜中被发现，还有线虫和其他多细胞微生物。
这些微生物出现需要较长的生物停留时间，并且他们的重要性还没有得到很好的体现。
给排水与环境工程专业英语
The human search for pure water supplies must have begun in prehistoric times. Much of that earliest activity is subject to speculation. Some individuals may have led water where they wanted it through trenches dug in the earth. Later a hollow log was perhaps used as the first water pipe.
Only by continual and costly attention to water quality control has it been possible to virtually eradicate waterborne diseases from developed countries. Such achievements must not, however, be allowed to mask the appalling situation regarding water supply and sanitation in much of the developing world. The growth of population in developing countries, due to the high birth rate, is such that unless strenuous efforts to increase water supply and sanitation facilities are made, the percentage of the world’s population with satisfactory facilities would actually decrease in the future. In developed countries, demands for water are now fairly static and basic waste quality-control measures are well established. However, many of the existing water-supply and sewage schemes are now relatively old so that their reconstruction will pose problems in the future. As knowledge of the effects of all forms of environmental pollution increases so new potential hazards appear, for example there is current concern about the possible carcinogenic hazards arising from the presence of minute concentrations of some organic compounds in water. Anthropogenic, or human-induced, pollutants have overloaded our envir commissioning of the first major public health engineering works of modern times. Thus by 1870 waterborne outbreaks had been largely brought under control in the UK and similar developments were taking place in Western Europe and the cities of the USA. The Industrial Revolution greatly increased the urban water demand and the late nineteenth century saw the construction of major water-supply schemes.

Unit5 A篇 Distribution systems（44）配水系统通常为住宅，商业，工业和消防系统设计，以达到满足对水需求相结合的目的。
在任何时候都应该达到令人满意的压力。
管道系统，抽水站，存储设施，消防栓，内部连接设备和其他附属设备是系统的主要组成部分。
配电系统通常可归类为网格系统，分支系统，或网格系统和分支系统的组合系统。
系统的结构主要取决于街道模式，地形，程度和当地区域的发展、位置的处理和存储工程。
图1示出了几种基本系统的性质。
网格系统的通常是优选的分支系统，因为它可以从至少两个方向上任何一点提供电力。
分支系统不能进行这种类型的流通，因为它有许多端子或死角。
一个网格或组合系统还可以将循环的馈线，从几个方向分发流量。
在一些会发生急剧变化的地形（丘陵或山区）的地方，它是用来划分成两个或多个服务区域或区域的常见分布系统。
在在海拔较高的低洼地区能保持合理的压力是一个难题。
通常的做法是各个系统互连，正常操作过程中互连后关闭阀门。
分配系统的特性可以通过用于给水量的压力来判定。
压力应该足够大用来满足消费者和消防的需求。
同时还不能过量，因为压力水头是重要的考虑因素。
此外，随着压力的增长，泄水量也增长，钱会被用于运输和处理产品而浪费。
因为在给水系统中的投资很大，经济设计的优化很重要。
给水系统中的水量是通过当地水的需求量再加上消防需求量。
管子的尺寸应该要避免高流速。
为了达到校方的需求，最小要选择直径为6的管子。
为了实现配水系统的水力设计，必须提供当地水的消耗率的预期，这些设计流量的方式，地理分布，和系统所需压力梯度。
应该再次强调，设计师应该调查的最高日用水率加防火和每小时的最大速率，以确定哪些管的设计。
消费的空间分布可以通过研究的人口密度，以及商业和工业用途的模型来确定或者预测改区域的估计。
学生们请注意，该区域的最大时用水量可能在住宅最大时的区域内，但不与商业或工业的最高值重合，反之亦然。
分配系统的分析通常是通过简化第一骨架的系统.这个可能涉及更换不同直径与当量管或更换与系统的当量管.当量管的管道系统的指定流速的水头损失与它所替换系统的水头损失是相同的。

Effluent quality for any sedimentation process is dependent upon previous water quality, coagulants added, mixing, flocculation, and filtration.
An efficiently designed vertical tank is more stable than a horizontal one. The rating of a vertical tank as related to the bulk settling velocity is usually 3.3 to 9.8 ft/h (1 to 3 m/h).
在预沉池，（被建议）规定的最短停留时间是3小时，尽管在一年的很 多时候，这个时间可能不足够去去除细小悬浮物质。
Chemical feed equipment may be provided ahead of presedimentation to provide prechlorination or partial coagulation for periods when water is too turbid to clarify by plain sedimentation.
钢筋混凝土池通常装配有持续的机械除泥设施。

The minimum recommended detention time for presedimentation is 3h, although at many times of the year, this may not be adequate to remove fine suspensions.
地表水（包含）在高浊度下就要求在化学处理工艺之前沉淀。
Presedimentation basins are constructed in excavated ground or out of steel or concrete.

Steel and concrete tanks are often equipped with a continuous mechanical sludge removal apparatus.
在一些圆形的池子，水流将会流进池子中央的絮凝室，出流水流从周围的围 堰垂直流出。

In rectangular tanks water flows horizontally to an end weir for discharge.
在矩形的水池，水流水平地流向池子终点的出水堰。
有效设计的竖流式沉淀池比平流池运行稳定。竖流式沉淀 池的速率与较大絮凝体的沉速有关，通常为3.3到9.8英尺/ 小时（1到3米/小时）

Recent developments have been made with the implementation of tube settling in the design of horizontal-flow settling tanks, which are said to overcome some of the previous difficulties and enable higher rates of sedimentation.

Sedimentation or clarification is the removal of particulate matter, chemical floc, and precipitates from suspension through gravity settling.
These basins may be constructed of concrete or steel in a wide variety of shapes and flow mechanisms.
这些池子用钢筋混凝土建成各种各样的形状和流动机制。
To minimize the effects of short-circuiting and turbulent flow, care is taken in the effective hydraulic design of inlet and outlet structures in all tanks.
除了预沉淀工艺，沉淀工艺通常先于混凝后于过滤。
Therefore, typical removals of regulated contaminants by sedimentation and filtration are reported according to coagulants used in conjunction with these processes for removal of a specific contaminant.
近期在平流沉淀池设计中，过沉淀管的安装取得了一些进步，据说这些进 步克服了先前的困难和提高了沉淀效率。
Upflow solids contact clarifiers, and horizontal-flow basins may increase their volumetric capacity 50 to 150 percent or more with the introduction of inclined tubes into their basins.
向上流的固体接触到澄清池和平流式沉淀池会增加50%—150%的处理能力， 或者通过采用斜管沉淀池可以增加更多的处理能力。
Similar or improved effluent quality is observed in these modified processes.
类似的或改善的出水水质在这些改进的工艺中被研究观察。
当通过平流池水太浑浊而不能澄清时，化学药剂投加装置就需要设置在 预沉池之前去预加氯或者添加部分的混凝剂。

Settling basins are usually provided for chemical coagulation or softening.
沉淀池通常投加一些混凝剂和软化药剂。
一些沉淀工艺的出流水质取决于进水水质、混凝剂的投加、混合、絮凝和过 滤。
With the exception of presedimentation, sedimentation processes are usually preceded by coagulation and followed by filtration.
这使得水的澄清是饮用水供应中地表水处理的至关重要一步，在很多情况下， 它也是决定全部水处理费用中主要的因素。
Poor design of the sedimentation basin will result in reduced treatment efficiency that may subsequently
