淮南采煤塌陷湖泊水环境评价

Water Environment Assessment of Lakes in Huainan Coal Mining Subsidence

选取淮南5个矿区的塌陷湖泊作为研究站点(XQ、ZJ、GQ、GB、DJ),对塌陷水体的水质情况进行分析评价。结果表明,淮南矿区塌陷水体主要为Ⅲ、Ⅳ类水质标准,水体富营养化问题比较严重,基本为"重度富营养化",N、P营养物质是塌陷水体主要特征污染物。淮南采煤沉陷区水体富营养化控制的关键在于对N、P的控制,未来在对塌陷水体开发利用的同时,也要加强对水资源的保护。

The collapsed lakes in the five mining areas of Huainan were selected as research sites(XQ,ZJ,GQ,GB,DJ)to analyze and evaluate the water quality of the collapsed water bodies.The results show that the water bodies in the Huainan mining area are mainly GradeⅢandⅣwater quality standards.The problem of water eutrophication is relatively serious,which is basica"yasevere eutrophication".N and P nutrients are the main characteristic pollutants of the collapsed water body.The key to the control of eutrophication in the Huainan coal mining subsidence area lies in the control of N and P.In the future,the development and utilization of subsided water bodies should also strengthen the protection of water resources.
