摘　　要：利用水泥的表面吸附和水化反应性质处理垃圾渗滤液生物处理出水可以取得很好的效果,COD的去除率可达69.5%。处理效果与水灰比、反应时间密切相关,低水灰比和较长反应时间对COD的去除更为有利。对处理前后水样的COD和TOC分析表明,水泥对非TOC贡献的COD有很强的去除效果。Cement was found effective for post treatment of the biotreated leachate of a Shanghai sanitary landfill. About 70% reduction in COD was achieved by adsorption of its organic constituents on cement particles and removal of its inorganic constituents by hydration reactions. A lower water to cement ratio and/or a longer reaction time resulted in a higher COD reduction. Most inorganic COD constituents were removed in the cement post treatment.
