摘要
以PAFC为混凝剂,选择某污水处理厂处理过程的前端、中端和后端为投药点,开展混凝沉淀实验,通过PAFC投加量的改变,分析上清液中污染物变化。结果表明:投加PAFC对SCOD和磷酸盐具有较好的去除能力,对NH3-N和TN的去除无贡献,少量PAFC对p H无影响,电导率有所提高。
As a coagulant,PAFC can be widely applied to pollutants removal in wastewater treatment. The coagulation and sedimentation test choose three points as PAFC dosing site,there are start-point,middle-point and end-point in technological process. Pollutants in the supernatant were changed with PAFC concentration. The results shows that Soluble Chemical Oxygen Demand( SCOD)and phosphate can been removed from wastewater by PAFC,nitrogen not,pH not change,wastewater conductivity can increase.
