人类排泄的粪便中,有100多种不同种类的病毒,其中有脊髓灰质炎病毒、柯克萨基病毒甲、柯克萨基病毒乙、与传染性肝炎病毒,与这些能致病病毒的同时,还有不能致病的噬菌体。现代的污水处理实践,必须防止这些病毒随污水排入游玩水体及下游居民饮用水源内。污水处理系统对去除病毒的效果,已经进行过许多试验研究。初步沉淀对污水中病毒,不能去除。生物滴沥池能去除少数。活性污泥法,经曝气6小时后,有显著去除效 There are more than 100 different kinds of viruses excreted by humans, including poliovirus, kirschkavirus A, coxsackievirus B, and infectious hepatitis virus, and at the same time these infectious viruses , As well as phages that can not be pathogenic. Modern sewage treatment practice, we must prevent these viruses with the water discharged into the swimming water and drinking water sources downstream residents. Sewage treatment systems have been tested in many ways to remove viruses. Precipitation of the virus in the sewage can not be removed. Biological drip pool can remove a few. Activated sludge method, after 6 hours of aeration, significant removal efficiency
