以铝箔酸、铝盐水和铝酸钙粉为主剂，亚铁酸为助剂．酸溶一步法合成聚合氯化铝铁．采用多因素正交试验研究了投料温度、加铁时间和保温时间对产品中铝含量、盐基度及其在处理污水过程中对污水中COD、TP和浊度的去除效果影响．结果表明，保温时间对产品中铝含量和盐基度及COD去除率影响最大，投料温度对浊度的去除效果最为明显，加铁时间对产品中铝含量、COD及浊度的去除率影响不大．%With aluminum foil acid, aluminum salt and calcium alumlnate powder as main ingredient, and ferrous acid as additives, the polyaluminum ferric chloride （PAFC） was synthesized via one-step acid-soluble method. Multi-factor orthogonal experiment was applied
