摘要
膜污染是一体式膜生物反应器运行中不可避免的问题。膜污染主要是污水中的污染物、微生物及其产生的胞外聚合物(EPS)、可溶性代谢产物 (SMP)类物质引起的。通过合理的设计及加强运行管理 ,结合有效的反冲洗和清洗措施 ,能够最大限度避免膜污染和恢复膜通量。
This paper briefly summarized mechanisms leading to contamination of membranes of submerged MBRs (membrane biological reactors), reviewing some strategies for dealing with the problems such as optimized design and manipulation of the equipment combined with rational backwashing and cleaning of membranes.
