摘　　要：本文以聚合硫酸铝铁(PAFS)和聚二甲基二烯丙基氯化铵(PDMDAAC)为原料制备了PAFS-PDMDAAC复合絮凝剂,并将其应用于实际含磷废水处理。实验结果表明,复合絮凝剂具有良好的除磷效果,在最佳工艺条件下,能将废水中的含磷量降至0.28mg/L以下,达国家污水磷排放一级标准(GB8978-1996),pH可控制在6.9～7.1之间,且可大大降低废水浊度,是一种具有良好发展前景的水处理剂。A composite flocculant of PAFS-PDMDAAC was prepared with PAFS and PDMDAAC and used in the removing of phosphorus in wastewater. The results showed that this composite flocculant had better effect of phosphorus removal and could reduce the concentration of phosphorus below 0.28mg/L under the optimum conditions, meeting the national discharging standard classl（GB8978-1996） for phosphorus, and pH removal could be controlled in the range of 6.9-7.1 and the turbidity was greatly lowered.
