污水粉煤灰-土地处理及地下水环境影响研究

Wastewater Coal Ash Land Treatment and Groundwater Environment Effects

工业污水排放不仅污染水环境 ,而且加剧了水资源的紧缺。利用热电厂粉煤灰在储灰场与污水混合、吸附、絮凝、生化降解以及土层截污降解综合处理污水 ,为探索以废治废和土地处理污水找到了一种可行的方法 ,同时 ,分析了下渗水对地下水的影响程度、范围及防治解决措施。

Drainage of wastewater has not only polluted water environment but also resulted in the shortage of water resource. This paper gives an account of the multiple treatment research process, which includes the mixing of coal ash with wastewater, adsorption, and land treatment. The authors have found a way of combating wastewater with solid waste, employed land treatment of wastewater, analyzed the extent and the limits of the effects and suggested the way for solution.
