摘要
在株洲市城镇污水处理厂提标改造工程实施前,开展中试规模的逆流连续砂滤设备对城镇污水进行深度处理,重点研究逆流连续砂滤池对废水中COD、SS、TP等污染物的去除效果,采用聚合硫酸铁(PFS)作为强化连续砂滤池除磷的混凝剂。试验结果表明,经过逆流连续砂滤池处理后,出水达到GB 18918—2002《城镇污水处理厂污染物排放标准》中的一级A标准。
With the background of Zhuzhou some sewage treatment plant,a pilot-scale countercurrent continuous sand filter equipment has been adopted to make deep treatment of town sewage before the implementing of its upgrading& construction project.The removal effects of countercurrent continuous sand filter on some pollutants such as COD、SS、TP are researched in detail,and the coagulant of this treatment is PFS for strengthening continuous sand filter phosphorous removal effects.The results show that the effluent can arrive at Class A of GB 18918—2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant after the treatment of countercurrent continuous sand filter.
