摘要： 采用浸没板式膜生物反应器(MBR)中试系统针对学生宿舍与食堂混合排水进行处理.系统采用A/O工艺,日处理污水4 m3.当进水BOD5和CODCr分别为90~450 mg.L-1,120~900 mg.L-1时,出水BOD5和CODCr分别为5~25 mg.L-1,8~45 mg.L-1,均得到了90%以上的去除率.同时对出水色度去除以及膜污染进行了全面实验研究,采用活性炭吸附可有效去除处理水色度,被污染的膜采用机械及药物方法清洗后可有效恢复通量.研究结果认为浸没板式膜生物反应器适用于中小规模的生活及产业有机废水的处理,具有广阔的应用前景.

Abstract: The treatment of the mixed wastewater from college dormitory and canteen by a submerged flat membrane bioreactor (MBR) system was studied experimentally. The anaerobic/oxic (A/O) MBR system has a capacity to treat wastewater up to 4 m3/d, through which the B0D5 and CODCr in the influent are 90-450 mg · L-1 and 120-900 mg · L-1, and they in the effluent are 5-25 mg · L and 8-45 mg · L-1 respectively, i.e. the removal rates are both over 90%. In addition, how to get rid of color contamination of effluent and membrane fouling was investigated. It was found that activated carbon can remove the contaminated color effectively, and the membrane can work well after cleaned up mechanically and chemically. A conclusion was drawn that the submerged flat MBR system is applicable to medium/small-scale domestic even industrial organic wastewater treatment with broad prospects in application.
