苏州市相城区水环境状况及污染防治对策

Water environment conditions and measures for pollution prevention and control in Xiangcheng District of Suzhou City

分析了苏州市相城区主要入阳澄湖(水源型湖泊)河道的水质现状,发现各水体水质均超出相应的标准限值,主要污染成因为:面源污染源强大,污水集中处理率偏低,水利工程破坏了天然的水力联系,工业企业布局散乱等。针对该区水环境形势的紧迫性,提出了面源控制、工业生态改造、污水处理、引水冲污、两湖强制性保护等污染防治对策。

Analyses on water quality of rivers in Xiangcheng District of Suzhou City show that the rivers flowing into Yangchenghu Lake （source lake） were above the water quality standard. The main pollution causes include severe nonpoint sources, low rate of centralized treatment, hydraulic connection interrupted by hydraulic structures, and dispersed layout of industrial enterprises. The serious situation for water environment protection was pointed out, and pollution prevention and control measures were proposed, such as non-point pollution remediation, ecotypical industrial alteration, sewage disposal, water diversion, and imperative protection for Yangchenghu Lake and Taihu Lake.
