摘要
介绍了山西阳泉污水处理厂环形A／O生物滤池的特点，并结合该厂污水处理工艺流程和主要工艺参数对实际运行情况进行了论述。运行结果表明：环状生物滤池较普通生物滤池对进水的水质水量有更大的耐冲击能力，除磷脱氮效率高40％～50％；经过二级处理，出水能够达到排放标准，三级处理后可作为中水回用。
The specialty of annular anoxic-aerobic biological filter of Yangquan Municipal Sewage Plant in Shanxi is presented. Based on the process flow and parameter, the run-time status is stated. The results indicate that annular biological filter has better ability to resist the impact of water quality and water quantity, the efficienty of dephosphovization and denitrification is advanced by 40 % -50 %, and the effluent can meet the national discharge standards through secondary treatment , and the effluent after third class treatment is capable of being used as intermediate water.
