摘　　要：通过小试试验研究活性污泥除磷的影响因素。碳源是影响活性污泥吸磷的一个重要因素。反应器中加入适量的碳源,在进行反复吸磷时,吸磷浓度平均为16.73mg/L;不添加碳源的活性污泥在进行反复吸磷试验时,吸磷浓度逐渐降低;活性污泥的存放时间能够提高活性污泥的初期吸磷浓度,当活性污泥进行反复吸磷试验时,存放时间越长,吸磷效果越差。Pilot tests were carried out investigate the influential factors of phosphorus removal by activated sludge. Adding carbon source in the reactor, in repeated P when P concentration was 16.73mg/L, without adding carbon source of activated sludge in repeated phosphorus uptake test, P concentration decreased; activated sludge storage time can improve the phosphorus concentration at the early stage of activated sludge, when activated sludge was repeatedly phosphorus absorption test, the longer the storage time, phosphorus absorption effect is worse.
