滇池水污染治理及防治对策研究

在总结滇池水污染问题及其成因的基础上,归纳得出湖泊老龄化、污染物超量排放、流域水资源匮乏、水流及物质交换不畅等是滇池水污染严重的主要原因,并针对性地提出了增加区域水资源量、入湖污染物总量控制、水污染综合治理、改变滇池运行方式等水污染防治策略及若干关键控制技术,提出了滇池环湖入湖污染物排放总量控制定额,并结合滇中调水规划,模拟预测引水济滇的水环境改善效果及改变滇池运行方式的水环境影响,可为滇池水污染治理及防治提供参考依据。

Investigation on countermeasures for water environment management and water pollution prevention in Dianchi Lake

After analyzing the water pollution situation in the Dianchi Lake,this paper points out some causes of water pollution,such as lake aging,contamination over-releasing,water resource shortage,and slow flowing of water and substance in and out,etc.The authors propose some strategies and key techniques for pollution control.It is suggested to enlarge the amount of regional water resources,to control the total amount of incoming pollutants,to treat water pollution comprehensively,and to improve the operation mode of the Dianchi Lake,etc.A total amount of the incoming pollutants from the surrounding area of this lake is specified.A simulation is conducted to predict the improvement of aquatic environment by diverting foreign water into the lake and by changing the operation mode of the lake.This investigation would provide some scientific bases for water pollution treatment of the Dianchi Lake.
