摘　　要： 试验通过对比分析向氧化沟系统投加填料前后的厌氧池释磷情况来探讨悬浮填料氧化沟系统的除磷途径,发现投加填料前后厌氧池释磷量分别为1.74 mg/L和-1.59 mg/L,投加填料后出现了"厌氧吸磷"现象,推测填料生物膜中存在能在厌氧条件下还原水中含磷化合物并释放出PH3的微生物,为市政污水中磷元素的高效回收利用提供了研究方向。 The test studied phosphorus removal pathway in the suspended carrier oxidation ditch system,through contrastive analysis the phosphorus release situation of anaerobic tank before and after adding carrier to the oxidation ditch system. The results found that the amount of phosphorus release in anaerobic tank were 1. 74 mg / L and-1. 59 mg / L respectively,then discovered the'anaerobic phosphorus uptake'phenomenon after adding fillers. Therefore,the article conjectured the presence of microorganism that was able to restore the phosphorus compounds and release PH3 at anaerobic conditions in the biofilm,and provided research directions for the efficient recycling of phosphorus in municipal wastewater.
