摘　　要：以氯化铝(AlCl3.6H2O)和氯化铁(FeCl3.6H2O)为原料,采用铝铁混合溶液加碱聚合这种新工艺,合成出无机高分子混凝剂—羟基聚合铝铁(HPAFC)。考察了HPAFC对模拟高浊度水的混凝性能,具体影响因素有投加量,pH,水力条件等。单因素实验结果表明,各因素的最佳取值分别为:投加量为7.75 mL/L,pH为9,混合转速为150 r/min,混合时间为30 s,反应时间为15 min。A new process of preparing hydroxyl polymeric aluminum-ferric chloride （HPAFC） coagulant was designed by adding base to a AI（III）-Fe（III） mixed solution and using iron chloride and aluminum chloride as raw materials. The flocculating property of HPAFC for the artificial muddy liquid was investigated, and the concrete influencing factors were the agent amount, pH and the condition of hydraulic power etc. The results of single factor experiments showed the best condition for each factor： the dose of HPAFC was 7.75 mL/L, the pH was 9, the admixture turn was 150 r/min, the mixing time was 10 s and the reacting time was 15 min.
