引水冲污工程治理东湖磷污染

Diverting Stream from the Yangtze River to East Lake for Phosphorus Loading Reduction

东湖的污染主要体现在氮磷的污染 ,以及由此而导致的水体富营养化 ,而目前正在实施的截污和清淤工程只能截取和清除部分磷污染源 ,对于剩余部分的污染源则有必要通过引水冲污工程来治理。在距沙湖最近的长江岸边设取水点 ,引长江水注入沙湖 ,随后将长江江水引入东湖。同时 ,并将部分受到污染的湖水通过青山港、武丰闸冲出东湖、排入长江 ,从而减少东湖污染物的总量 ,降低东湖的污染程度 ,增强东湖水体的自净能力 。

Heavy loading of nutrients, mainly phosphorus, has led to eutropohication of East Lake in Wuhan City. Pollution abatement projects are being implemented in recent years, including diversion of sewage and dredging in part of the lake. This paper deals with the ensuing work aimed at water quality improvement of the lake, involving the suggestion of diverting stream of the Yangtze to 'flush' the nutrients loaded water out of the lake through the existing channnel and sluice gates to the Yangtze.
