Abstract
Taihu Lake is located at the center of Changjiang delta region. The Lake and its effluent rivers are important water sources for about 40 million inhabitants and rapidly increasing industrial factories in Shanghai, Jiangsu, and Zhejiang. The pollutants originate mainly from acidy rain, home sewage of the vast number of inhabitants, livestock manure, agricultural fertilizers, and pesticides applied over fields in the drainage basin, and the industrial sewage. Some research studies have indicated that industrial sewage, domestic wastewater, and agricultural non-point source (NPS) pollutants accounted for 16, 25, and 59 % of total nitrogen for water eutrophication , respectively, and for 10, 60, and 30 % of total phosphorous, respectively, in Taihu Lake. Due to pollutants, the Lake water is getting highly eutrophic, with frequent blooms of blue-green algae . Compared with point source pollutants, diffuse pollution is much complicated and difficult to control . It is clear that NPS pollution in Taihu Lake region has been quite serious and has become the main threat for water environment health. Thus, combating NPS pollution must be paid great attention.
