摘　　要：为降低城镇污水处理厂出水磷含量,在生物除磷的基础上辅以化学除磷。化学除磷剂的投加会生成化学污泥而导致污泥量的增加,且化学污泥若进入生化系统会对污泥活性带来负面影响。以石家庄市桥东污水处理厂为例,从多个角度分析了化学除磷剂对生化系统的影响及其成因,并提出了有效解决措施。In order to reduce the phosphorus content in the effluent from municipal sewage treatment plant, chemical phosphorus removal is used as an auxiliary on the basis of biological phosphorus removal. The chemical phosphorus removal agent can produce chemical sludge and increase the amount of sludge. If chemical sludge enters into the biochemical system, the activity of activated sludge is negatively affected. Taking Shijiazhuang Qiaodong Wastewater Treatment Plant as an example, the effect of chemical phosphorus removal agent on the biochemical system and its reason were analyzed from several angles, and the effective solution to the problem was put forward.
