摘　　要：采用CASS池结合ClO2消毒工艺处理某医院污水,结果表明,出水COD、BOD5、氨氮、总磷的质量浓度和去除率分别为23～65 mg.L-1、77.38%～90.81%;11～65 mg.L-1、66.36%～90.91%;0.12～2.87 mg.L-1、73.57%～98.47%;1.0～1.4 mg.L-1、58.32%～65.01%;总大肠杆菌群低于1 000.L-1,去除率为97.08%～99.83%;接触消毒池出水余氯为3.1～3.5 mg.L-1。各项指标基本达到了污水综合排放标准(GB 8978-1996)的二级排放标准。表明CASS池结合ClO2消毒工艺能有效的处理医院废水。By employing CASS pool with ClO2 disinfection process in treating with hospital sewage,the effluent COD,BOD5,ammonia nitrogen and TP concentrations and removal efficiency were 23～65 mg·L-1,77.38%～90.81%;11～65 mg·L-1,66.36%～90.91%;0.12～2.87 mg·L-1,73.57%～98.47%;1.0～1.4 mg·L-1,58.32%～65.01%,repectively;total coliform group was lower than 1000 per liter,the removal rate was 97.08%～99.83%;residual chlorine was 3.1～3.5 mg·L-1 in the effluent water of contact disinfectant pond.All the indexes basically reached the requirements of the secondary emission standards of integrated wastewater discharge standard（GB 8978-1996）.It was found that CASS pool combined with ClO2 disinfection process could effectively deal with hospital sewages.
