摘　　要：垃圾渗滤液的处理一直是近几年污水处理领域的热点、难点,随着垃圾填埋场的新建利用,研究与开发垃圾渗滤液处理技术方法颇具社会意义和环境意义。文中通过电絮凝法去除垃圾渗滤液中有机物的试验,结果表明,电絮凝法处理垃圾渗滤液的最佳条件为:极板材料采用铁电极,极板间距为20 mm,pH为6～8,电流密度为3 A/mm2,在最佳条件下对垃圾渗滤液COD的去除率可达到65.4%。The treatment of landfill leachate has been the hot and difficulty spot in recent years. Along with the building of land- fill, the technological Study and development of leachate treatment have social and environmental significance. The tests of organic matter removal in the leachate by using electric floceulation show that the best conditions of landfill leachate treatment are using iron electrode plate material, plate spacing 20 ram, pH 6 - 8, current density of 3 A/ram2 , and the removal rate of COD in landfill leaehate can reach 65.4%.
