摘　　要：研究了4种无机絮凝剂AlCl3、PAC、FeCl3、PFS对200mg/L和400mg/L HPAM(水解聚丙烯酰胺)溶液的絮凝作用。测定了絮凝后上清液中HPAM剩余浓度以及Al3+和Fe3+的残留浓度。通过对絮凝效果的分析比较发现,絮凝法可以有效地去除污水中的HPAM,且AlCl3效果最好,去除率可达90%,絮体较为密实,上清液粘度接近清水粘度。AlCl3,PAC ,FeCl3,PFS flocculation of HPAM solution has been investigated. HPAM concentration, Al^3＋ concentration and Fe^3 ＋ concentration in solution were also examined. Through analyzing flocculation performance it is found that flocculation can eliminate HPAM availably in wastewater. And flocculant AlCl3 is the best suited one, the rate of removal of HPAM is above 90 %. The viscosity of HPAM solution is decreased to the same level as that of water.
