摘　　要：城市饮用水处理厂沉淀池排泥水的回用是国内外节能减排和城市节水措施中广泛关注的问题。沉淀池排泥水中富集大量的污染物,特别是含氮污染物,具有较高浓度的二氯乙酰胺生成势,二氯乙酰胺的高毒性致使沉淀池排泥水无法直接回流到工艺中。UV/H_(2)O_(2)氧化工艺对二氯乙酰胺含氮前体物具有很好的去除效果,能显著降低排泥水中二氯乙酰胺生成势,氧化处理后的排泥水可回流到工艺中,具有节约水资源和保护环境的双重意义。The retrieval and utilization of urban drinking water treatment plant tank platoon sludge has become necessary for the implementation of water-saving ways and effective measures.The sludge water of tank platoon,especially nitrogen pollutants concentration of pollutant has the very high dichloride acetamide generating potential,dichloro acetamide high toxicity make tank platoon sludge water can’t directly back into the process.UV/H_(2)O_(2)oxidation process of dichloro ethyl amide nitrogen precursor material has good removal effect,can significantly reduce the row of the mud dichloride acetamide generating potential,row mud after oxidation treatment can back into the process,has the dual significance of water saving and environment protection.
