复合式膜生物反应器废水处理技术研究进展

Research progress in wastewater treatment techniques by using composite membrane bioreactor

复合式膜生物反应器结合了传统膜生物反应器与接触氧化工艺的优点,能在维持稳定高效的有机物去除率前提下,有效减缓膜污染,减少剩余污泥的排放,并为同步脱氮过程提供良好环境,因此近几年逐渐成为研究热点。文章综述了其构成、工作原理、类型及在处理不同废水中的应用,并展望了今后研究的努力方向。

The composite membrane bioreactor combined with the advantages of conventional membrane bioreactor and contact oxidation technologies can keep the organism removing rate stable and efficient. On this premise, the membrane pollution can effectively be slowed down and the residual sludge discharge can be reduced. Moreover, it can provide good environment for the synchronous denitrification process. Therefore,it has gradually become a research focus in recent years. Its constitution, operating principle, types and application to the treatment of different kinds of wastewaters are summarized and its future research directions are forecasted.
