摘要
目前随着经济和社会的发展,水资源日益稀缺,如何对受污染的水资源进行处理,使其资源化已成为世界各国缓解水资源危机的重要途径之一。因此,城市污水处理工艺技术的研究和发展引起了人们的广泛关注。从我国城市污水处理工艺的类型以及优缺点出发,比较各种工艺在我国的应用现状,阐述我国城市污水处理的研究进展,并展望城市污水处理工艺的发展方向,旨在为以后具体污水处理项目的工艺选择提供参考。
With the development of the economics and society and the increasing water resources scarity, sewage water treatment presents an important way in both pollutants reduction and water scarcity relief. Consequently, the development in processing technologies of municipal sewage has greatly drawn people＇ s attention. The paper begines with introduction about various processing technologies of municipal sewage in recent China. Then their associated advantages and disadvantages are examined as well. Furthermore, possible processing technology development is discussed and conclusion is drawn.
