摘　　要：采用活性炭吸附法和超滤法,对城市污水厂二级出水进行了深度处理试验研究。试验结果表明,粒状活性炭对污水中溶解性有机物有较好的去除效果,当允许出水CODC r为15 mg/L以下、炭层厚度为2 m、滤速为3 m/h、5 m/h和7 m/h时,吨水用炭量基本在0.2 kg/m3。超滤对水中浊度去除率在95%以上。超滤膜清洗采用洗涤剂配制的清洗液及5%的H2SO4、4%的NaOH溶液清洗,膜通量可得到较好的恢复。Advanced treatment of wastewater was done as test by GAC and supermembrane. GAC can adsorb effectively organics in wastewater from water treatment plant. With 2 m GAC thickness and below 15 mg/L of organics in water at 3m/h,5 m/h and 7 m/h current velocity, GAC quantity used per ton water is some 0.2 kg. Supermembrane test remove turbM from wastewater by over 95 %. Washing supermembrane by washing solution made with detergent and 5 % of H2SO4,4% of NaOH is effective.
