摘要
强化生物除磷(EBPR)工艺是目前国内外广泛应用的废水除磷技术之一。微生物的研究对于提高EBPR系统的除磷稳定性有着非常重要的意义。综述了EBPR系统中聚磷菌和聚糖菌的种群分析及其代谢机制、聚磷菌与聚糖菌之间竞争的影响因素等方面的研究进展。分析了目前相关研究中存在的不足,并展望了今后相关的研究发展方向。
The enhanced biological phosphorus removal(EBPR) as a high efficient phosphorus removal technology is widely applied in wastewater treatment,it has broad application prospect both at home and abroad.Polyphosphate accumulating organism(PAOs) and glycogen accumulating organism(GAOs) are two main microorganisms which could influencr the stability of EBPR process.Therefore,the studies of the two microorganisms have significant importance in improving the stability of EBPR process.Base on the comprehensive literature review,the paper summarize the species and metabolism mechanism of PAOs and GAOs,the factors which could influence the competition of PAOs and GAOs in EBPR process are also introduced.Finally,the direction of future research of PAOs and GAOs is prospected.
