湖库内源污染成因及常用治理技术

Causes of Endogenous Pollution in Lakes and Reservoirs and Common Treatment Technologies

为保持湖库生态环境的稳定,分析了湖库污染现状及特点,指出了湖库内源污染成因,提出了几种常用的内源污染治理技术:底泥清淤,引流冲污,水下森林,投加菌种,曝气增氧,化学絮凝处理,生物治理,催化增效。展望了内源污染治理的发展趋势,有针对性地选用合适的技术路线和处理措施,构建健康的水生态体系。

In order to maintain the stability of the lake and reservoir ecological environment,this paper analyzes the current situation and characteristics of lake and reservoir pollution,points out the causes of lake and reservoir endogenous pollution,and puts forward several common endogenous pollution control technologies,i.e.sediment dredging,drainage and flushing,underwater forest,adding bacteria,aeration and oxygenation,chemical flocculation treatment,biological treatment and catalytic efficiency enhancement.The development trend of endogenous pollution control is prospected,and appropriate technical routes and treatment measures are selected to build a healthy water ecosystem.
