摘　　要：为探讨厌氧池不同季节的释磷状况,提高生物除磷的效果,选取北方地区沈阳南部污水处理厂现场进行实地研究。结果发现,夏季厌氧池释磷最大效率为192%,最小效率为73%,平均释磷效率为106%;冬季厌氧池释磷效率最大效率为49%,最小效率为8%,平均释磷效率为22%,这表明厌氧池冬季释磷效率明显低于夏季。In order to study the phosphorus release in Anaerobic pool in different seasons and improve the effect of biological phosphorus removal,the field study was carried out in the Sewage Treatment of Shenyang,northern China.The results showed that the maximum eff iciency of phosphorus release was 192%,the minimum efficiency was 73% and the average efficiency was 106% in summer,and the maximum efficiency was 49%,the minimum efficiency was 8% and the average efficiency was 22% in winter.The phosphorus release efficiency of Anaerobic pool in winter was lower than that in summer.
