学院论文代写:国家供水私有化和水处理技术

国家供水私有化是政府解决供水问题的另一种方法。政府可以将供水过程传输给私人玩家。私营企业是价值驱动型企业,拥有必要的技能,并有潜力将不可行的水处理系统转变为可行的水系统。私有化将带来专门知识、人力资本和加强以水处理为基础的水处理和净化技术。在这个过程中,政府将把所有权转让给私营企业。这种方法的优点是可以通过使用私营企业的经验和技术来改善供水。然而,这一过程所涉及的迫在眉睫的风险是将重点放在利润的产生上,而不是私人企业在中国的供水。使用的操作和维护组件将具有更高的质量(Hazelton, J。,2014)。在这一过程中,为了去除含油物质和积聚的藻类,将对供水系统和管道进行定期清洗。此外,还将制订一项有效的废物管理办法,以便从水中清除废物。将在私营化方法下制订适当的排水和废物处理办法。此外,政府将推动私人玩家建立预防性维护计划。这主要是为了提高水处理系统的效力和效率,并延长其使用时间。私营企业将确保最佳地利用现有资源进行水处理和分配。在这种方法中,政府有风险将私人参与者的安全用水分配到该国的特定地区。私营化通过利益最大化、管理各种资源和智力资本的参与来提高系统的效率。

Privatization of water supply in the country is another method which can be used by the government to resolve the water supply problem. The government can transfer the process of water supply to private players. Private players are value driven, posses requisite skills and have the potential to transform unviable water treatment systems into feasible water systems. Privatization would bring in expertise, human capital and enhanced water treatment based technologies for water treatment and purification. Under this process, government would be transferring ownership rights to private players. The advantage of this method is scope for improvement in water supply through use of experience and technology of private players. However, imminent risk involved in this process is focus on profit generation rather than water supply in the country by private players. Operational and maintenance components used would be of higher quality (Hazelton, J., 2014). Under this process, periodical cleaning of water supply chain and pipes would take place for removing oily material and accumulated algae. Moreover, an effective waste management would be developed for removal of waste from the water. Proper drainage and disposal of waste materials would be developed under privatization method. Moreover, the government would push private players for setting up of preventive maintenance program. This would be primarily done for increasing effectiveness and efficiency of water treatment system and increasing their duration. Private players would ensure optimum utilization of available resources for water treatment and water distribution. In this method, the government runs the risk of biased allocation of safe water by private players to specific areas in the country. Privatization brings efficiency in the system through maximization of benefits, management of various resources and involvement of intellectual capital.

它们将营养物质转化为不同形式的稀有生物。机械水系统采用生物、物理和化学等多种工艺相结合的方法对水进行处理和净化。该方法在人工环境中采用自然水处理工艺(Habiba, U。阿贝丁,医学博士,肖,R。,(2014)。机械水处理方法使用各种部件,包括水箱、泵、管道、研磨机和鼓风机。系统中的水流是通过各种机械技术来控制废水的处理。这种方法在土地稀缺的地方非常有效。

兼性泻湖一般采用水处理-泻湖技术进行水处理。这种水处理工艺是从稳定池发展而来的,使用机械或扩散空气系统。该方法不能用于高出水固体含量超过100 mg/l的水容器。为了防止水质退化,已经发展了水文控制性泻湖。在这一过程中,废水在河流禁止排放后聚集在泻湖中(Chalmers, K。戈弗雷,J。林奇,B。,2012)。这种方法最重要的优点是,如果需要,可以提供额外的水处理。人工湿地可以通过地表水和地下水两种不同的形式来利用。这些系统需要植物的根和养分来转移氧气。这些系统用于狭长流域的水处理,并作为水生植物的蓄水池。此外,在水处理过程中还可采用间歇式和循环式滤砂器。然而,这两种方法在水处理中的应用由于废水的应用而有所不同。循环过滤器可用于生物水处理(Huq, F。史蒂文森,M。Zorzini, M。,2014)。

They convert nutrients into different forms of scarce bio-mass. Mechanical water system uses combination of various processes including biological, physical and chemical for water treatment and purification. This method uses natural water treatment process in human constructed environment (Habiba, U., Abedin, Md., Shaw, R., (2014). The mechanical water treatment methodology uses various components including tanks, pumps, pipes, grinders and blowers. Flow of water in the system is controlled through various mechanical techniques for treatment of waste water. This method is highly effective where there is scarcity of land.
Facultative lagoons are generally used for water treatment through aquatic treatment-lagoon technology. This water treatment process evolved from stabilization ponds and uses mechanical or diffused air systems. This method cannot be used for water containment with high effluent solids exceeding 100 mg/l. Hydrograph controlled release (HCR) lagoons have been evolved for prevention of water quality degradation. In this process, waste water gets accumulated in a lagoon after stream prohibits discharge (Chalmers, K., Godfrey, J., Lynch, B., 2012). The most important advantage of this method is provision for additional water treatment, if required. Constructed wetlands can be utilized in two different forms either through use of surface water flow and subsurface flow. These systems require roots of plants and nutrients for transfer of oxygen. These systems are used in long, narrow basins for water treatment and serves as a water reservoir for aquatic plants. Moreover, sand filters including intermittent and recirculating sand filters can be used in water treatment process. However, application of both these methods in water treatment differs due to waste water application. Recirculating filters can be used for biological water treatment (Huq, F., Stevenson, M., Zorzini, M., 2014).
