厌氧膜生物反应器处理生活污水的研究进展

Research progress on treatment of domestic sewage by anaerobic membrane bioreactor

厌氧膜生物反应器(AnMBR)对生活污水处理效果与好氧处理接近,而且产泥量较低,还能产生有用的能源。综述了目前AnMBR处理生活污水的相关研究进展,分析了处理过程中的膜污染控制措施,水力停留时间(HRT)、污泥龄(SRT)、温度等对处理性能的影响,处理过程中生成的溶解性甲烷的回收以及AnMBR的中试研究状况等。最后还展望了在推进AnMBR全面应用过程中尚需要深入研究或解决的问题。

The treatment effect of domestic wastewater by anaerobic membrane bioreactor （AnMBR） was close to aerobic treatment,and it can not only produce a low mud, but also useful energy. The recent studies of the imple- mentation of AnMBR on domestic wastewater treatment were reviewed.The membrane fouling measures in treatment process, influence of hydraulic retention time, sludge age and temperature, recovery of dissolved methane generated during processing were summarized. The research status of AnMBR in pilot scale was also analyzed. At last, the prob- lems that need to be solved in the deep application of AnMBR were discussed.
