摘　　要：某污水处理厂根据除氟生产工艺需要,对4种除氟剂进行了选型对比试验,认为其中2种(GMS-F3和YYHBL-Ⅱ)满足使用要求。通过除氟剂用量、pH以及PAM添加量等因素控制,可将光伏废水中的F-浓度降低到1.5 mg/L以下,达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。通过小试能较好地进行除氟剂选型,且所选除氟剂能满足生产达标排放要求,同时该试验数据也能较好地指导生产实践。In accordance with the requirements of the fluoride removal production process at a wastewater treatment plant,four new types of defluorination agents were evaluated systematically.Two of them,GMS-F3 and YYHBL-Ⅱ,meet the usage requirements of the wastewater treatment plant.By controlling factors such as the amount of defluorination agent,pH,and PAM addition,the fluoride ion concentration can be reduced to below 1.5 mg/L,meeting the level A standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).Through experimental research and engineering application data analysis,it has been found that small experiments can effectively select defluorination agents in a wastewater treatment plant,and the selected agents can meet production discharge standards.At the same time,this experimental data can also provide good guidance for production practice.
