膜生物反应器在医院污水处理中的应用

采用全封闭式膜生物反应器处理医院污水,出水水质良好,ρ(COD)<60 mg/L,ρ(NH3-N)<6 mg/L,浊度<0.3NTU的概率约为95%,ClO2消毒后出水中未检测出细菌和粪大肠菌群,可满足GB 18466—2005《医疗机构水污染物排放标准》的要求。高效过滤器对曝气尾气中的微生物粒子截留效果良好,大大降低了MBR系统因气溶胶扩散可能产生的二次污染和威胁。此外采用了远程监控技术,可以通过公共网络对污水处理系统进行监视和控制,最大限度地保证系统的稳定运行和保障操作人员的生命安全。

APPLICATION OF MEMBRANE BIOREACTOR IN TREATING WASTEWATER FROM HOSPITALS

Better effluent quality was achieved when fully enclosed membrane bioreactor was used for treatment of hospital wastewater.Some monitoring indices could meet the requirements of "Discharge Standard of Water Pollutants for Medical Organization"(GB 18466—2005),such as,ρ(COD)<60 mg/L,ρ(NH3-N)<6 mg/L,no microorganisms and fecal coliform bacteria were detected and turbidity lower than 0.1 NTU at probability of 95%.Good separation effect of suspended solid in atmosphere by a high efficiency filter;and remote controll system could operate and monitor the equipments by public network.
