海绵浸没式膜生物反应器在废水处理中的研究进展

RESEARCH PROGRESS OF SPONGE-SUBMERGED MEMBRANE BIOREACTOR IN WASTEWATER TREATMENT

海绵浸没式膜生物反应器(sponge-submerged membrane bioreactor,SSMBR)作为一种新型的废水处理工艺,具有可持续通量大、污染物去除率高、跨膜压差(TMP)增量小、膜污染率低等优异特性,在处理污废水领域有着广阔的研究和应用前景。介绍了SSMBR装置的结构特征,综述了国内外对SSMBR性能的研究进展,并简单探析了膜污染的形成过程及水力停留时间和微生物絮凝剂对膜污染的影响。

Sponge-submerged membrane bioreactor as a novel type of bioreactor had an extensive research and application prospect in wastewater treatment for its large sustainable flux,high pollutant removal rate,low transmembrane pressure and low fouling rate. This paper introduced the structural characteristics of SSMBR and summarized the research progress of the performance of SSMBR at home and abroad. And it simply analyzed the formation of membrane fouling and the effects of hydraulic retention time and microbial flocculant on membrane fouling.
