【摘要】 向膜生物反应器内投加40g·L-1粉末活性炭处理尾水,运行效果良好。排泥和水力停留时间对处理效果有很大影响,流量和曝气量在一定程度上决定了膜污染的进程,粉末活性炭吸附降解了一些易引起膜污染的有机物,改变了污泥的性质,使膜通量得到改善。气洗和反冲洗能很好的维持膜通量,离线清洗可使膜通量基本恢复。更多还原

【Abstract】 Adding properly PAC (40 g·L-1) to the MBR, the water quality of effluent was effectively improved. Discharging sludge and HRT had a great impact to the results of the experiment. In some extent the flux and aeration determine the process of fouling. PAC could adsorb and degrade some organic compounds which caused foul substances in the membrane. PAC improved the activated sludge’s characterizations and made a great contribution to maintain high membrane flux. The airwash and backwash could maintain high flux. And the flux of membrane could be recovered mainly by wash away the system.更多还原
