摘要
目的 :了解生物滤池对生活污水及医院污水微生物的影响。方法 :于生物滤池处理生活污水及医院污水前后分别取水样测定污水中的细菌总数及粪大肠菌群的含量。结果 :生物滤池对生活污水细菌总数的去除率为 99.95 % ,对粪大肠菌群的去除率为 99.99%。生物滤池对医院污水细菌总数的去除率为 99.80 % ,对粪大肠菌群的去除率为 99.97%。结论 :生物滤池对生活污水及医院污水微生物的去除有明显的效果 。
Objective:To study the effect of activated bio-filter on microorganism of domestic sewage and hospital sewage.Methods:Aerobic bacterial count and fecal coliform in sewage of doemestic and hospital were analysed before and after activated bio-filter treatments.Results:After activated bio-filter treatment,the removal rate of Aerobic bacterial count and fecal coliform was 99.95% and 99.99% in domestic sewage;the removal rate of Aerobic bacterial count and fecal coliform was 99 80% and 99 97% in hospital sewage.Conclusions:It was effective to remove microorganisms in domestic sewage and hospital sewage by the use of activated bio-filter.In order to guarantee the safety of epidemiology,sewage,espically the hospital sewage must be disinfected.
