膜生物反应器脱氮除磷工艺的研究进展

Progress of Membrane Bioreactor Technology for Nutrient Removal

膜生物反应器是近年新发展起来的高效污水处理工艺。文章重点介绍了膜生物反应器的脱氮除磷工艺 :单一反应器间歇曝气膜生物反应器工艺和A/O形式的膜生物反应器工艺。总结了国内外研究的工艺特点、技术参数和处理效果 ,分析了技术参数、运行方式对处理效果的影响 。

Membrane Bioreactor is a new efficient wastewater treatment technology developed recently. In this article, two main types of membrane bioreactor processes for nutrient removal were presented: single-stage intermittent aeration process and A/O-type process. The characteristics of processes, operational parameters and treatment performance, as reported by domestic and abroad researchers, were summarized. The effects of operational parameters and modes on the performance were analyzed, and the further research and application prospects were proposed.
