Virus removal has become big problems in water sanitation. Small treatment process with net like contact media was investigated for its virus removal ability. This study was divided into four parts ; (1) Mixing condition in disinfection process was examined, because small plant is difficult to equiped with the apparatus which can mix well disinfectant with water. It was clearly shown that inactivation of microorganisms was strongly influenced by mixing condition. (2) Virus detection method was examined. The method which can detect viruses from waters of low concentration in viruses has been developed. (3) More than 99% of viruses could be removed by the process with net like contact media under low BOD load, showing that the process studied here might be used for tertiary wastewater treatment. (4) Experiments using the model of small treatment plant in use showed that poliovirus of around 99% was removed under BOD load applied to plants treating domestic wastewater.E. coli phage Qbeta could increase in number in the treatment process, which decrease the value of E. coli phage as indicator for virus pollution.

去除病毒已经成为水卫生的大问题。研究了网状接触填料小型处理工艺对病毒的去除效果。本研究主要分为四个部分：（1）针对小型工厂难以配备能使消毒剂与水充分混合的设备，对消毒过程中的混合条件进行了考察。这清楚地表明，微生物的灭活受到混合条件的强烈影响。(2)检查病毒检测方法。建立了一种从低病毒浓度的沃茨中检测病毒的方法。(3)在较低的BOD负荷下，网状接触填料对病毒的去除率可达99%以上，表明该工艺可用于污水的三级处理。(4)使用小型处理厂模型进行的实验表明，在对生活污水处理厂施加BOD负荷的情况下，脊髓灰质炎病毒的去除率约为99%。大肠杆菌噬菌体Q β在处理过程中数量增加，使E.大肠杆菌噬菌体作为病毒污染的指示物。
