呼吁回收并减少垃圾英语作文
呼吁回收并减少垃圾英语作文In the face of mounting environmental challenges, it is crucial that we, as a global community, take concerted action to protect our planet. One of the most pressing issues we confront today is the relentless generation of waste, which not only pollutes our ecosystems but also poses significant threats to human health and wildlife. Therefore, I am compelled to advocate for the importance of recycling and reducing waste in our daily lives.Recycling stands as a cornerstone in mitigating the environmental impact of waste. By transforming discarded materials into new products, we conserve valuable resources, reduce energy consumption, and minimize greenhouse gas emissions associated with manufacturing from raw materials. It is a cyclical process that encourages sustainability and fosters a circular economy where waste is minimized and resources are maximized.Moreover, reducing waste at the source is an equally vital strategy. This can be achieved through conscious consumption habits, such as opting for reusable products instead of single-use items, embracing minimalism, and making informed purchasing decisions that prioritize durability and eco-friendliness. By doing so, we can significantly cutdown on the volume of waste generated, thereby easing the burden on our landfills and oceans.Education plays a pivotal role in fostering a culture of recycling and waste reduction. Raising awareness about the consequences of improper waste disposal and highlighting the benefits of recycling can inspire individuals to adopt more environmentally responsible behaviors. Schools, communities, and governments should collaborate to implement comprehensive education programs that empower citizens with the knowledge and tools to make a difference.Governments, too, have a responsibility to enact policies that promote recycling and discourage wasteful practices. This includes implementing extended producer responsibility programs, offering incentives for recycling, and enforcing stricter regulations on waste management. By setting ambitious targets for waste reduction and recycling rates, governments can drive systemic change and encourage innovation in waste management technologies.Lastly, businesses have a significant role to play in this transition. Adopting sustainable production methods, minimizing packaging, and investing in recycling initiatives not only contribute to environmental preservation but also enhance their brand reputation and long-term profitability. Consumers are increasingly supportive of companies that demonstrate a commitment to sustainability, making it a win-winsituation for both the environment and the economy.In conclusion, the dual approach of recycling and reducing waste is imperative for preserving our planet's health and ensuring a sustainable future. It is a collective responsibility that requires the active participation of individuals, communities, governments, and businesses. Let us unite in our efforts to minimize waste, maximize recycling, and create a cleaner, greener world for generations to come.。

Whether formeasuring industrial or domestic waste flows, theuse of flowmeters to help gather discharge data canplay a vital role in helping to keep wastewateremissions within the prescribed limits.In cases where an industrial site, business or otherheavy water user discharges large quantities ofwastewater to a public water treatment works,accurate flowmetering is especially desirable toensure that the emitter is correctly billed for theamount of water discharged.—The applicationIn most cases, the point at which wastewater flowsare measured is the pumping station, which relayswastewater from industrial sites and/or domesticsewer networks from treatment at one or morewastewater treatment plants. For the reasonsstated before, as well as the need to make sure thatwater treatment works are not overloaded withexcessive quanitities of wastewater, it is necessaryto measure the quantities of water being pumped asclosely as possible.One way of measuring these quantities is toestimate the flow by multiplying the volume ofwater that flows each time the pump is started bythe number of pump starts over a set period oftime. This gives an approximate total volume figurefor a known period which can then be used toestimate the flow.Another, more precise way, is to use a flowmeter toprovide an exact and continuous measurement ofthe volume of water that flows through awastewater distribution system.—Gaining an enhancedoverview of wastewaterflows using ABB’sWaterMaster2ACCU R ATE WA S TE WATE R F LOW M E A S U R E M E NT | WATER M A S TER| A D/FLOW/006–EN R E V. A—The challengeThere are two main challenges that users face whenselecting a flowmeter for measuring wastewater. The firstchallenge is the choice of the right flowmeter for the job.There are various options available, each offering their owndistinct set of advantages and drawbacks depending on thecharacteristics of the application, including the ability tohandle high velocity flows of particulates and suspendedsolids as well as the overall installation space available.The ability to handle high velocity flows where solids may bepresent, rules out many conventional flowmeteringtechnologies. Differential pressure meters such as orificeplates and flow nozzles, for example, could become clogged.Mechanical meters are also unsuitable. With moving partssubject to wear and tear, these meters can quickly sufferreduced accuracy, leading to either under or over-registration of flows. Furthermore, the need for mechanical meters to be periodically tested, recalibrated and repaired means that they have to be removed, requiring users either to replace the meter with a temporary device or cease measurement until the meter is refitted back into the line. Ultrasonic flowmeters also suffer various drawbacks which can make them unsuitable. Transit time meters in particular can struggle to handle flows with high levels of particulate matter, requiring a strainer to be fitted. Both transit time and Doppler meters can also be affected by velocity profile distortions, requiring from 10 to 40 upstream diameters, depending on the severity of the disturbance. The turndown of ultrasonic meters is also limited within an ideal range of 20:1 to 40:1. Ultrasonic meters can also be difficult to install and set up, especially where high accuracy is required.As a further consideration, there may also be the need for data from the meter to be accessed from a central location, particularly on large, dispersed sites or where the meter is situated in a hard to reach location.Adding flowmeters to pumping installations can help to provide a more precise measurement of waste water flows.—A solutionElectromagnetic flowmeters offer a good alternative for water distribution applications. Compared to other flowmeter types, electromagnetic flowmeters offer greatly enhanced accuracy and repeatability throughout their operational life, with uncertainty of ±1 % reading or better. With no moving parts, they do not suffer from problems with wear and tear, minimizing maintenance and require no upstream strainers to filter sediment. A choice of flow primary linings affords further protection against coating and high sediment flows, with users able to choose from a variety of materials, including ceramic linings for particularly abrasive flows.The ability of electromagnetic flowmeters to better handle distorted velocity profiles also reduces the amount of piping upstream and downstream of the meter.Modern electromagnetic flowmeters are also capable of being buried, eliminating the need for the construction of costly installation chambers.Available in sizes from 10 to 2400 mm (3/8 to 96 in), ABB’s WaterMaster electromagnetic flowmeter is ideally suited to wastewater flow measurement applications.A key feature is the WaterMaster’s revolutionary octagonal sensor design. By improving the flow profile, the octagonal design minimizes the upstream and downstream pipe lengths required from the point of installation, greatly reducing the cost of fitting the meters into new or existingpipelines.3 ACCU R ATE WA S TE WATE R F LOW M E A S U R E M E NT | WATER M A S TER| A D/FLOW/006–EN R E V. AABB’s WaterMaster electromagnetic flowmeter enables operators to gain an enhanced overview of their wastewater flows.The WaterMaster also features on-board verification capability. Called VeriMaster, it assures operators of the performance of the meter through constant self-checking. When coupled with ABB’s VeriMaster software tool, it enables operators to produce a printed verification certificate for regulatory compliance.The effects of signal noise are also minimized by the WaterMaster’s use of advanced Digital Signal Processing (DSP) technology. This enables the WaterMaster’s transmitter to separate the real signal from the noise, thereby providing high quality outputs especially in harsh environments involving vibration, hydraulic noise and temperature fluctuation.All WaterMaster sensors have a rugged, robust construction to ensure a long, maintenance-free life even under the most difficult conditions experienced in water and waste water applications. The sensors are inherently submersible (IP68, NEMA 6P) as standard, ensuring suitability for installation in chambers and metering pits which are liable to flooding.All sizes of the WaterMaster are buriable and are straightforward to install, with installation merely involving excavating to the underground pipe, installing the sensor and wiring the factory pre-potted cabling to the transmitter and then backfilling the hole. Operation has been simplified by the use of ABB’s universal Human Machine Interface (HMI), which has now been extended across its range of instrumentation products. Based on Windows™ technology, the HMI simplifies operation, maintenance and training, reducing cost of ownership and providing a consistent user experience. Data can also be accessed remotely via HART™, Profibus DP™ and Modbus™ communications.Installation is further simplified by the WaterMaster’s ‘Fit and Flow’ data storage feature. On initial installation, the selfconfiguration sequence automatically replicates into the transmitter all calibration factors, meter size and serial numbers as well as customer site-specific settings. This eliminates the opportunity for errors and leads to increased speed of start-up.Measurement integrity is ensured by redundant storage of data in both the sensor and transmitter memory, which is continually updated during all operations. The on-board sensor memory eliminates the possible problems associated with pluggable data memory modules.WaterMaster is proven to be robust and reliable, with unmatched diagnostic capabilities providing the right information to keep the process up and running. Alarms and warnings are classified in accordance with NAMUR NE107.The meter is also verified to OIML R49 type ‘P’ requirements to ensure the highest accuracy and long term performance of the system by continuously self-checking the sensor and transmitter in the field.All ABB flow meters are designed and manufactured in accordance with international quality procedures (ISO 9001) and are calibrated on nationally-traceable calibration rigs to provide the end-user with complete assurance of both quality and performance.

AN OVERVIEW ON CHALLENGES FOR WASTE MANAGEMENT IN HONG KONG
Waste is a common problem of affluent societies. Especially when people can afford greater convenience and more purchases, they tend to throw away more rubbish. Hong Kong is no exception to this.
Growing Wasteloads
Hong Kong, like many developed places, has seen its wasteloads grow as its economy has grown. Municipal wasteloads have in general been increasing since 1986 - when the EPD was formed - mirroring Hong Kong's rapid economic expansion over the same period. At the same time, the population has grown by more than one million people and each person is throwing away more waste. In 2008, the per capita disposal rate of municipal solid waste was 1.35 kilogrammes per day.
Municipal solid waste includes waste from households, industry and commercial operations, but landfill s are also under tremendous pressure from construction waste. In 2006, the Government introduced the construction waste disposal charging scheme and the quantity of construction waste disposed of at landfills deceased from 6,560 tonnes per day in 2005 to 2,660 tonnes per day in 2008.
Outlook
The continued growth in wasteloads means Hong Kong is running out of landfill space far earlier than expected, and the existing landfills will be filled up, one by one, in mid to late 2010s if waste levels continue to increase at current levels. Unless solutions are identified immediately, we could face a crisis in the next decade of having nowhere to put the thousands of tonnes of waste thrown away each day.
New landfill sites must be identified. However, the community has become more resistant to having waste facilities near their neighbourhoods. The government have already started to consult the public on the options.
Landfill space should also be conserved by state-of-the-art technologies that reduce the bulk volume of waste requiring disposal. After extensive review, the EPD is now planning to develop the Integrated Waste Management Facilities that would adopt advanced incineration as core technology to reduce bulk waste volume and to recover energy. Organic Waste Treatment Facilities are also being planned to recycle source-separated organic waste to useful products.
WASTE REDUCTION
Waste reduction is often associated with recycling, but it is more complex than that. Avoiding the generation of waste in the first place and minimising waste are also crucial measures in any waste reduction strategy.
Individuals can reduce their waste by buying items with less packaging, using reusable bags for shopping, and separating waste paper, metals and plastics from our daily waste for recycling.。
