白洋淀流域某污水处理厂深度除磷运行效果分析

Analysis of the Operation Effect of Deep Phosphorus Removal in a Sewage Treatment Plant in the Baiyangdian Basin

为实现深度除磷,以白洋淀流域某污水处理厂为研究对象,通过长期现场检测该厂不同工艺段TP变化,分析各工艺段的除磷效果以及除磷技术的制约因素。结果表明:在一般情况下,依靠生物池化学强化生物除磷和后置磁混凝化学除磷等工艺耦合除磷,可实现出水TP≤0.2mg/L。

To achieve deep phosphorus removal,a sewage treatment plant in the Baiyangdian Basin was taken as the research object.Through long-term on-site monitoring of TP changes in different process stages of the plant,the phosphorus removal effect of each process stage and the con-straints of phosphorus removal technology were analyzed.The results indicate that in general,coupling processes such as chemical enhanced biologi-cal phosphorus removal in biological ponds and post magnetic coagulation chemical phosphorus removal can achieve effluent TP≤0.2 mg/L.
