太仓市应急水源地水质影响分析

根据现状水质资料和未来规划资料,采用模型预测与机理分析相结合的方法,系统分析了未来太仓市应急水源地——长江边滩水库水质状况。结果表明:由于拟建取水口远离岸边,沿岸固定源和浏河污水排放对应急水源地水质影响较小;库内可能发生的富营养化可通过生物措施得以解决;水库本身具有蓄淡避咸、蓄清避污功能,因此具备较高的抗环境风险能力。

Impact analysis of water quality of emergency water source at Taicang City

According to the present and planned water quality data series,a model prediction combined with a mechanism analysis was selected and the water quality status of the emergency water source——the Biantan reservoir of the Changjiang River,in the future,at Taicang City——was studied systematically.The results revealed that the sewage discharge of the point source along the river bank and the Liuhe River had a slight effect on the drinking water,because the planned water intake was far away from the river bank;the possible eutrophication of the reservoir could be prevented by biological measures;and the reservoir had high environmental anti-risk ability due to its capacity to store freshwater and avoid saltwater intake,and to store clear water and avoid pollution.
