摘 要

太湖流域经济发达，位于我国前列，但其环境问题也饱受社会各界关注，本文首先从脱氮除磷工艺和流域治理方案两个方面总结国内外研究进展，为对太湖流域水污染治理提供参考。然后介绍太湖流域的自然经济条件和水污染现状以及氮磷污染带来的湖泊富营养化问题，分析太湖流城水污染的原因和危害，进而了解太湖流域水污染的污染程度、基本特征以及进行综合治理的必要性，通过总结太湖流域近20年来的水污染治理实践和经验，分析其成效与存在的问题。

最后以太湖流域生活污水氮磷总量的控制为切入点，分别从源头预防、事中控制和末端治理三个方面提出氮磷污染治理的建议，从农业、工业和大气沉降三个方面补充氮磷污染治理的措施。

关键词：太湖流域 流域治理 生活污水 脱氮除磷

Study on total nitrogen and phosphorus control measures

of domestic sewage in Taihu River Basin

ABSTRACT

Taihu Lake Basin is economically developed and in the forefront of our country, but its environmental problems are also concerned by all sectors of society. Firstly, this paper summarizes the research progress at home and abroad from two aspects of nitrogen and phosphorus removal process and Watershed Governance scheme, providing a reference for water pollution control in Taihu Lake Basin. Then it introduces the natural economic conditions and water pollution status of Taihu Lake Basin and the lake eutrophication caused by nitrogen and phosphorus pollution, analyzes the causes and hazards of water pollution in the flow city of Taihu Lake, and further understands the pollution degree, basic characteristics and the necessity of comprehensive treatment of water pollution in Taihu Lake Basin. Through summarizing the practice and experience of water pollution treatment in the past 20 years in Taihu Lake Basin, it analyzes that Effectiveness and existing problems.

Finally, taking the control of the total amount of nitrogen and phosphorus in the domestic sewage of Taihu Lake Basin as the starting point, this paper puts forward suggestions on the treatment of nitrogen and phosphorus pollution from the three aspects of source prevention, event control and end treatment respectively, and supplements the treatment measures of nitrogen and phosphorus pollution from the three aspects of agriculture, industry and air subsidence.

Key Words: Taihu Lake Basin; Domestic sewage; Denitrification and Dephosphorization; Watershed Management
