| 摘 要： | 某再生水厂的供水能力为10×104m3/d,采用混凝、沉淀、过滤工艺,原水为城市污水厂的二级处理出水.结合实际运行数据,分析了该工艺及其各单元对几种主要指标的去除效果.监测结果显示,该工艺对COD、SS、TP具有较好的去除效果,但对TN、BOD5的去除率较低,对此可在前端增加曝气生物滤池等单元加以解决.该研究对于污水再生处理工艺的选择具有指导意义.

| Abstract: | The coagulation/sedimentation/filtration process is adopted in a reclaimed wastewater treatment plant with design capacity of 100 000 m3/d.Its raw wastewater is the secondary effluent from a municipal WWTP.The removal efficiencies of main pollutants in this plant were assessed using the actual operation data.The process can remove COD,SS and TP effectively,while the removal rates of TN and BOD5 are very low.Biological aerated filter should be applied to lower nitrogen and organic matters.The assessment cont... |
