摘　　要：采用超滤组合工艺去除某污水厂二级出水中内分泌干扰物邻苯二甲酸酯类,主要研究了精滤柱、活性炭柱、混凝沉淀3种不同预处理下超滤对邻苯二甲酸酯的去除效果及去除机理.结果表明3种工艺对邻苯二甲酸二丁酯(DBP)和邻苯二甲酸二乙酯(DEP)都有一定的去除效果,其中混凝沉淀-超滤的去除效果最好,对DBP和DEP的去除率均在50%以上.The removal of phthalate esters in the secondary effluent of the sewage plant by the combined process of UF （ultrafiltration） was studied. The experiment focused on the removal mechanism of the three processes,which were miner filtration pole-UF, the active carbon pole-UF and coagulation sedimentation-UF. The results showed that pthalate esters were partly removed by these three processes,and the coagulation sedimentation and UF was the best one,which could remove DBP and DEP at the ratio of over 50 %.
