摘 要: 强化生物除磷(EBPR)工艺可以获取高效的除磷效果,已在很多污水处理厂得到广泛应用。但是大型污水处理厂在相当多的条件下,EBPR工艺也会出现周期性除磷效果的波动和不充分。针对这一难题,研究者试图采用许多手段来研究工艺中的主要微生物。文章针对典型的EBPR工艺和碳源、pH值、温度等因素对EBPR工艺中两类细菌聚磷菌(PAOs)和聚糖菌(GAOs)竞争的研究进展进行了论述,并展望了未来的研究方向。 With high efficient phosphorus removal,the enhanced biological phosphorus removal (EBPR)process has been widely applied in many wastewater treatment plants. Though EBPR process is indeed capable of efficient phosphorus removal,disturbances and insufficient phosphorus removal are observed at large scale plants. In terms of solving the problem main microorganisms in the process were studied. The affecting factors such as carbon source,pH value and temperature were discussed,especially competition between polyphosphate accumulating organism(PAOs)and glycogen accumulating organism (GAOs). Potential areas in future studies were also proposed.
