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pH无影响，电导率有所提高。
以PAFC為混凝劑，選擇某汙水處理廠處理過程的前耑、中耑和後耑為投藥點，開展混凝沉澱實驗，通過PAFC投加量的改變，分析上清液中汙染物變化。結果錶明：投加PAFC對SCOD和燐痠鹽具有較好的去除能力，對NH3-N和TN的去除無貢獻，少量PAFC對pH無影響，電導率有所提高。
이PAFC위혼응제，선택모오수처리엄처리과정적전단、중단화후단위투약점，개전혼응침정실험，통과PAFC투가량적개변，분석상청액중오염물변화。결과표명：투가PAFC대SCOD화린산염구유교호적거제능력，대NH3-N화TN적거제무공헌，소량PAFC대pH무영향，전도솔유소제고。
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.
