摘　　要：一体化氧化沟生物除磷是在氧化沟前加一只厌氧生物选择器，进行磷的厌氧释放，在后续好氧阶段进行磷的过量吸收，最后污水中的磷以排除剩余污泥的方式排出系统。试验的目的是确定生物选择器的最佳设计参数，试验指出处理城市污水厌氧选择器的最佳运行条件是ＨＲＴ 为８０ｍｉｎ ，ＭＬＳＳ为１ ５００ｍｇ／Ｌ。Biological phosphorus removal of Integrated Oxidation Ditch is to set up an anaerobic biological selector before the Oxidation Ditch to release phosphorus and absorb excessive phosphorus in the following aerobic process. Finally, it is discharged in the way of wasted sludge. The main aim of the experiment is to achieve optimum parameters of selector for engineering design, and the results show that the optimum operating condition for municipal wastewater treatment is that HRT is about 80 min, MLSS is about 1 500mg/L.
