东太湖水源地水质保护工程改善效果

Improvement effect of water quality protection project in the East Taihu Lake water source

由于近年来东太湖水污染事件日益频发,为解决水质问题,本文调查了吴江区东太湖水源地水质及水生态现状。结合底泥释放试验了解东太湖底泥特性。分析吴江区水厂取水口主要有污染底泥的卷起和释放、水草的聚集与腐烂、工程后回淤及沿岸带腐烂物质堆积等问题;针对相应问题提出具体工程措施,并通过工程前后的水质资料对比,分析水质的改善效果和生态效益。

Since water pollution incidents of the East Taihu Lake occur frequently in recent years,current situation of water quality and water ecology in the East Taihu Lake water source of Wujiang District is investigated in order to solve water quality problems in the paper. Meanwhile, sediment release tests are combined for comprehending the sediment characteristics in the East Taihu Lake. Problems of Wujiang District water plant intake are analyzed,mainly including rolling and releasing of polluted sediment, accumulation and decomposing of water plants, project post-dredging,accumulation of rotting material along the coastal,etc. Specific engineering measures are proposed so as to correspond problems. Water quality data before and after the project are compared for analyzing the improvement effect on water quality and ecological benefit.
