摘要
工程应用的结果表明 ,一体式好氧中空纤维膜—生物反应器用于处理医院污水在技术上是可行的 ,其对医院污水中的COD、氨氮、浊度的平均去除率分别可达 80 %、93%、83% ,出水水质良好、稳定、无色无嗅 ,优于国家建设部颁发的医院污水排放标准。系统已稳定运行 6个多月 ,膜阻力上升稳定、缓慢 ,其间没有对膜进行过任何清洗。
The results of engineering application of integrative hollow fiber membrane-bioreactor for treatment of hospital wastewater show that the use of this process for treatment of hospital wastewater is technically feasible. The removal rate of 80%, 93%, and 83% is achieved respectively for COD , NH 3-N, and turbidity in hospital wastewater. The effluent is colorless and odorless with good and stable quality, and surpasses the hospital wastewater discharge standard issued by the Ministry of Construction. The system has run for more than 6 months without any chemical cleaning. The transmembrane pressure increases slowly and steadily.
