摘　　要：在设定的絮凝条件下,以济南市水质净化一厂初沉池进水为试验水样,无机高分子絮凝剂聚合氯化铁铝(PFAC)和有机高分子絮凝剂聚丙烯酰胺(PAM)为试验药剂,浊度、COD、溶解氧等为测定指标,进行了一系列气动絮凝试验。试验结果表明,采用气动絮凝方式强化城市污水一级处理效果明显。单独投加25mg/LPFAC时,浊度、COD去除率分别为90%、78.5%,溶解氧增加230%;组合投加20mg/LPFAC+1.0mg/LPAM时,浊度、COD去除率分别为92.4%、78.6%,溶解氧增加246%。Under the condition of set coagulation, a aerated flocculation test was conducted with the influent of the primary sediment pool of a water purifying plants as the water sample, inorganic polymer flocculent PFAC and organic polymer floceulent PAM as test chemicals, and turbidity,COD,DO as determining indexes. It was showed that enhancing primary municipal sewage treatment by aerated flocculation had obvious effect; when being single dosage of 25mg/L PFAC, the turbidity and COD removal rate reached to 90% and 78.5% respectively,DO content was increased by 230%;when being combining dosage of 20mg/L PFAC＋1.0 mg/L PAM,turbidity and COD removal rate reached to 92.4% and 78.6% respectively,DO content was increased by 246%.
