英国论文代写哪家好：加纳的水质和供水问题
在加纳，水质和供水问题仍然是政府关注的关键领域。由于全国各地水的短缺和质量低下，该国主要地区的供水问题仍然存在。在快速城市化和人口增长的帮助下，经济的增长给现有的满足市民需求的配水系统带来了严重的压力。目前的水资源无法满足人们对洁净水的需求。该国许多地区的供水问题已导致严重的环境和健康问题。成龙,一个。,2013年。水传播疾病对加纳人民构成重大威胁。该国报告的大多数死亡，特别是儿童死亡，可归因于供水问题。政府一直在努力通过实施各种提供安全、清洁饮用水的方法和技术来解决这一问题。在比较不同供水方式之前，最好先评估供水问题的原因。水问题的主要原因包括基础设施不足和居民对住宅缺乏认识。政府可采用多种方法在农村供水(Ameyaw, E。成龙,一个。,2015)。

应为水处理部署各种方法，包括技术选择、私有化和改组现有基础设施。技术选择包括为水净化设计的简单水处理技术。这些技术选择可进一步分为三种主要的水处理系统，即机械水处理系统、水处理系统和陆地水处理系统。这些工艺过程各有优缺点。机械水处理系统使用在人类建造的环境中进行的工艺，并在自然系统技术实施范围有限的地方进行。在这种方法下，包括泻湖和水文控制区在内的水系统是各种各样的水处理选择(Chumakoy, A。,2014)。这些系统可以通过湿地的建设来改善水处理过程。该系统的主要优点是可以应用于各种天气条件下的水处理方法。另一方面，陆地系统利用土壤、植物和废水中的养分。

In Ghana, water quality and water supply problem remains key areas of concerns for the government. Water supply problem persists in major parts of the country due to scarcity and low quality of water throughout the country. Growth in economy aided by rapid urbanization and increasing population has put severe stress on existing water distribution system for meeting citizens’ requirements. Present water resources are incapable of meeting clean water needs of the people. Water supply problem in many parts of the country has resulted in serious environmental and health issues (Ameyaw, E., Chan, A., 2013. Waterborne diseases posses a significant threat to people living in Ghana. Majority of reported deaths in the country particularly among children can be attributed to water supply problem. The government has been trying its best to resolve the issue through implementation of various methods and techniques for supplying safe and clean drinking water. Before comparison of different methods for water provisions, it would be better to assess reasons for water supply problem. Major reasons for water problem include inadequate infrastructure and lack of residential recognition to dwellers. Various methods can be used by the government for supplying water in the country (Ameyaw, E., Chan, A., 2015).

Methods including technological options, privatization and restructuring of existing infrastructural facilities should be deployed for water treatment. Technological options include simple water treatment technologies designed for water purification. These technological options can be further classified into three principal types of water treatment systems namely mechanical, aquatic and terrestrial. Each of these technological processes has its own merits and demerits. Mechanical water treatment system uses processes within a human constructed environment and performed in places where scope for implementation of natural system technologies is limited. Aquatic systems including lagoons and hydrograph controlled release areas are various water treatment options available under this method (Chumakoy, A., 2014). These systems can be modified by supplementing the water treatment process through construction of wetlands. The major benefit of this system is that it can be used in various methods for water treatment under varied weather conditions. On the other hand, terrestrial systems make use of nutrients available in soil, plant and waste water.
