豫西阳平河河滩矿渣污染研究

Slag Pollution of Beach in Western Hinata River

在对研究区内阳平河河道水质和河滩矿渣数量及现状调查基础上,研究了河道水质重金属超标状况,以及河道矿渣和沿岸矿渣的废物类型,并用潜在生态危害指数法(RI),分析了矿渣重金属的生态危害程度,结果表明,研究区内地表水铜、锰超标,超标率分别为11.11%和27.78%;研究区内矿渣均不属于危险废物,河道矿渣属于第Ⅰ类一般工业固体废物,污染程度为轻微生态危害;沿岸矿渣属于第Ⅱ类一般工业固体废物,污染程度为很强生态危害,其中重金属Cu、Mn、Pb对环境生态的影响较大。

Based on the investigation of the water quality of the Hinata River and the quantity and status of the slag in the research area,the status of heavy metal in river water quality and the type of waste in river slag and coastal slag were researched.The potential ecological risk index method(RI)was used to analyze the ecological hazard of heavy metals in slag.The results show that the surface water copper and manganese in the study area exceed the standard,and the over-standard rates are11.11% and 27.78%;The slag in the study area is not classified as hazardous waste,the river slag belongs to the general industrial solid waste of Class I.and the degree of pollution is a slight ecological hazard;the coastal slag belongs to the general industrial solid waste of Class II,and the degree of pollution is a strong ecological hazard.The Cu,Mn and Pb have a great impact on the environmental ecology.
