河流污染治理技术在滇池河道水环境整治中的集成应用

Integral Application of River Pollution Treatment Technology in Dianchi River Water Environmental Treatment

入湖河道治理是滇池污染治理的重要措施之一,通过开展截污、清淤、生态河堤治理、入湖口湿地等工程建设,达到改善滇池水环境的目的。该文以西坝河截污及水环境治理工程为例,调查分析河道污染状况及成因,研究物理法、化学法以及生物-生态技术等污染治理技术的适用性,并加以集成应用,最终实现减少流入滇池的城市污染负荷、改善河道水质及周边环境、提升河道行洪能力的综合治理目标。

The entering-lake river treatment is one of the important measures for the treatment of Dianchi pollution.The engineering construction of sewage interception,silt clearing,ecological riverbank treatment and wetlands at mouth of entering lake reaches the objective to improve the water environment of Dianchi.Taking Xiba River sewage interception and water environmental treatment project as an example,the article investigates and analyzes the river pollution status and cause,studies the applicability of the pollution treatment technologies by the physical process, chemical process and biological-ecological process to integrate for the application,and finally to realize the general treatment objective for the decrement of urban pollution load flowing into Dianchi, improve the river water quality and surrounding environment,and enhance the flood control capacity of river.
