【摘要】 目的　评估不同水处理方法 (沉淀过滤法、超滤法、臭氧消毒法、氯消毒法 )对病毒的清除效果。方法　在污水中人为添加定量的柯萨奇病毒作为病毒指示剂 ,采用不同的水处理方法处理污水 ,以细胞培养法 ,细胞半数致死剂量 (TCID50 )为检测指标 ,检测各种水处理方法对柯萨奇病毒的清除效率。结果　臭氧消毒法对病毒清除最为有效 ,其次为沉淀过滤法与超滤法 ,氯消毒法效果不明显。结论　对污水中病毒的清除不能采用单一工艺 ,需多种工艺互补才能有效清除病毒更多还原

【Abstract】 Objective To evaluate the inactivation effectiveness of different water treatments(sediment filtration,ultra filtration,ozone disinfection and chlorine disinfection on enteric viruses in wastewater.Methods Cell-cultured coxsackie virus B3(CoxB3) was added to sterilize secondary efflluent as virus indicator,then the water sample was treated by different water treatments respectively,TCID 50 was used as test index to assess virus elimination of the four water treatment techniques.Results CoxB3 could be effectively controlled by adequate ozone disinfection practice.Sediment filtration and ultra filtration almoset had the same effec tiveness on virus elimination.Chlorine disinfection couldn′t achieve remarkable removal efficiency.Conclusion Ozone disinfection was one of the most effective ways to clean up wastewater,but enteric virus in wastewater can not be successfully eliminated by only one treatment,combination of physical treatments and chemical disinfection techniques were recommended.更多还原
