强化生物除磷污泥厌氧磷释放影响因素的研究进展

Research progress of influence factors of anaerobic phosphate release from enhanced biological phosphorus removal sludge

强化生物除磷(EBPR)工艺的活性污泥含有大量的磷,并且具有厌氧条件下释放磷酸盐的能力,从EBPR剩余污泥中回收磷酸盐具有极大的发展潜力。因此,优化影响EBPR污泥厌氧释磷的各项参数,使其能够最大程度的释放磷酸盐,是目前研究的重点。本文对EBPR污泥厌氧释磷影响因素的最新进展进行了分析和归纳。尽管很多研究者在该领域进行了研究并取得了一定成果,但依然存在很多争议和无法解答的问题,还需要进行进一步的研究。

Activated sludge in enhanced biological phosphorus removal （EBPR） has a high content of phosphorus and can release phosphate under anaerobic conditions. Phosphate recovery from EBPR excess sludge has great potential, so the vital problem focuses on the optimization of the parameters that affect anaerobic phosphate release of EBPR sludge in order to maximize the release of phosphate. The recent advances in phosphate release from EBPR sludge are analyzed and summarized in this paper. Although plenty of research in this field has been done and some results are obtained, many disputed and unanswered questions still exist and further study is needed.
