太湖入湖河流水环境综合治理

Overall Treatment of Water Environment for Inflow Rivers of Lake Taihu

简述了太湖入湖河流水污染控制的基本思路、关键环节和主要方法。分析了太湖流域15条主要入湖河流规划综合治理区污染源现状,提出污染控制对策建议和重点整治工程,并预测削减入湖河流的污染物总量。通过整治工程的实施,截至2009年5月,15条主要入湖河流中劣Ⅴ类水质的河流已从2007年的9条下降为3条,湖体也由中度富营养转为轻度富营养,综合治理初见成效。

key teches and main methods were put forward basic on water pollution control of inflowing rivers of Lake Taihu. The pollutant source situation in the comprehensive treatment zone of the 15 major inflowing rivers was analyzed for pollution control suggestion and main projects to forecast amount of reducing pollutants into the Lake. By the May 2009 among the 15 major inflow rivers, regulating projects had improved 6 of 9 rivers whose water quality were worse than Grade V and changed water-body eutrophication of the Lake from medium level into light level. The comprehensive treatment of Lake Taihu water guality had achieved initial success.
