混凝沉淀+电氧化反应器联合处理垃圾渗滤液的试验研究
Journal: Ecological Environment and Protection DOI: 10.12238/eep.v4i4.1428
Abstract
研究了采用混凝沉淀+电氧化反应器联合处理垃圾渗滤液工艺。首先对垃圾渗滤液进行混凝沉淀,投加FeCl30.4g/L,,对渗滤液的CODcr的去除率可以达到35%,但对氨氮基本没有处理效果。出水再利用电氧化反应器处理,电氧化反应器反应级数为一级,当电流密度为20mA•cm-2,反应时间140min,对废水的CODcr的再次去除率可达90%以上,对废水中氨氮的去除率在98%左右。采用混凝沉淀与电氧化反应器联合处理垃圾渗滤液,处理效果好,出水稳定,对废水中CODcr、氨氮均有很高的去除效率,是垃圾渗滤液适宜的处理技术。
