摘　　要：以聚合氯化铝和聚丙烯酰胺为原料,复配絮凝工业含铝的柠檬酸废水,考察了不同废水pH,复配絮凝剂投加量、有机无机絮凝剂投加比不同的情况下铝元素的去除率。研究结果表明,在pH在7左右、投加量为30 mL、聚铝∶聚丙烯酰胺的比为1∶4、静置时间为2 h、混合搅拌速率为50 r/min的条件下,复配絮凝剂对废水中铝的去除率可达94%以上。With polyaluminium chloride and polyacrylamide as raw material, compound with flocculation industrial citric acid wastewater containing aluminum, the different waste water pH was examined, compound with floeculant dosing quantity, organic and inorganic floceulant dosing ratio of different cases, the removal rate of aluminum. The research results showed that the pH around 7, dosing amount to 30 mL, polyaluminium chloride to polyacrylamide ratio of 1 ： 4 and let stand for 2 h, mixed stirring speed of 50 r/min, under the condition, compound for wastewater removal rate can reach more than 94%.
