摘　　要：采用静态试验的方法研究了温度、MLSS、VFA浓度、碳源种类等对反硝化聚磷污泥厌氧释磷的影响，研究结果表明：随着温度的升高厌氧释磷速率有所增加，但厌氧释磷速率与温度之间并不是简单的线性关系，温度对厌氧释磷的长期作用还有待考察；在一定范围内增加污泥浓度与碳源可以有效地强化厌氧释磷效果；反硝化除磷脱氮工艺处理实际生活污水时，建议厌氧池停留时间为4～6h，在工艺首端设置水解酸化池将有利于厌氧释磷效果的强化。The denitrifying phosphorus removal techniques can solve both the problem of scarcity of carbon and the conflict of SRT between PAOs and nitrobacteria, so it has good application foreground. Since the phosphorus release is the key process of denitrifying phosphorus removal, it is necessary to investigate the factors that may influence the phosphorus release process. This paper discusses a series of tests that were operated to study the influence of temperature, MLSS,VFA concentration and carbon source. The results show that the phosphorus release rate increases with the rising of temperature, but the relationship between them is not linear and the long-term impact of temperature still needs to be investigated. In a certain range, enhancing MLSS or organic carbon concentration can promote the phosphorus release process markedly. In the practical treatment of living sewage, it is suggested to have it stay for 4 to 6 hours in the anaerobic tank, and it will be favorable to add an acidification tank before the anaerobic tank.
