摘　　要：巢湖流域TP本底浓度偏高,降低水体TP含量可有效抑制巢湖蓝藻水华的暴发。污水处理厂尾水中的TP为巢湖总磷污染的重要来源之一,合肥市某污水处理厂极限除磷提标设计中,通过改造现有构筑物,新建高效气浮处理单元,将出水TP在0.3 mg/L降至0.05 mg/L以下,建设、运营管理方便。详细介绍了该厂提标改造的工艺路线、主要构筑物设计,可为其他类似工程的建设提供借鉴。The background concentration of TP is high in Chaohu Lake,and reducing the content of TP in water can effectively inhibit the outbreak of cyanobacteria bloom in Chaohu Lake.TP in the tail water of sewage treatment plant is one of the important sources of total phosphorus pollution in Chaohu Lake.In the design of advanced phosphorus removal of a sewage treatment plant in Hefei,by transforming the existing structures and building a new high-efficiency air flotation treatment unit,the effluent TP was reduced from 0.3 mg/L to less than 0.05 mg/L,which was convenient for construction,operation and management.The process route and main structure design of the upgrading and reconstruction of the plant were introduced in detail,which can provide reference for the construction of other similar projects.
