摘要
结合城市污水处理厂升级改造除磷工程实例,探讨强化除磷工艺,即CASS工艺。经过实证研究发现,合理选择药剂剂投加位置,可使污水厂出水TP稳定达到0.30mg/L以下。这符合《城镇污水处理厂污染物排放标准(GB18918-2002)》表1一级A标准限值,达到预期设计效果。
Combined with the example of the phosphorus removal project in the upgrading of urban sewage treatmentplant,this paper probed into the measures for strengthening the phosphorus removal process of CASS.Through theempirical research,it was found that the reasonable selection of the dosing position of the reagent could make the effluent TP of the sewage treatment plant be stable below0.30mg/L.This conforms to the"discharge standar of pollut?ants for Municipal Wastewater Treatment Plant(GB18918-2002)"Table1,the first class A standard limit,andachieve the desired design results.
