摘要
水体富营养化是世界性难题,其中磷通常是主要限制因子。生物除磷工艺简单,污泥产量少,可节约能源,运行费用也较低,便于操作和磷的回收。在介绍水体中磷的来源、污染特点及其造成危害的基础上,着重综述了国内外生物除磷的研究进展,并对生物除磷存在的问题和发展趋势提出了一些看法。
The phosphorus is the limited nutrient in eutrophication of the waterbody,which is a significant problem worldwide. The introduction to the sources, contaminated characteristics and side-effects of phosphorus in waterbody were given,the updated progresses in biological removal of phosphorus in waterbody was summarized because of which was low-cost, efficient, convenient in operation and reclaimation, and perspective as well as development trend were suggested.
