【灭杀病毒的效果较差】
[Poor efficacy in killing viruses]
通过传统加氯消毒工艺应用于医院污水消毒过程中分析,采用此工艺对许多如大肠菌群、沙门氏菌等菌群的去除率极高,而对病毒取出所达到的数量级极少。
Through the analysis of traditional chlorination disinfection process applied in hospital sewage disinfection process, the removal rate of many bacteria such as coliform bacteria and Salmonella is very high, but the number of viruses removed is very small.
尤其对肠道病毒进行灭杀时,由于其忍受力更强于肠道致病菌或大肠菌群,在通过次氯酸钠进行处理之后,仍可在排放的污水中检测出一定数量的病毒。因此,肠道致病菌或大肠菌群阴性无法确定病毒致病危险是否存在。
Especially when killing enterovirus, because of its stronger tolerance than enteropathogenic bacteria or coliform bacteria, a certain number of viruses can still be detected in the effluent after being treated with sodium hypochlorite. Therefore, it is impossible to determine whether the risk of viral pathogenicity exists because of the negative intestinal pathogenic bacteria or coliform flora.
