摘　　要：研究一种专用于磷化废水脱磷处理的絮凝剂及其处理工艺。结果表明,当磷化废水pH值调为8.0-9.0、处理温度为20±5℃时,除磷絮凝剂的最佳投加比例为:磷含量(mg.L-1):石灰投加量(mg):絮凝助剂A(mg.L-1)=38:200:1。处理后的磷化废水中总磷含量为0.1mg.L-1,达到了国家一级排放标准,且磷的去除率较传统方法提高20.2%,吨污水药剂成本下降了17.1%,具有明显的经济与环境效益。We study on the process and the condition of the phosphorous removal way of the phosphorous waste water from the process of the pre - painting of refrigerator. It shows that when we adjust the pH as 8.0 - 9.0, the temperature as 20±5℃. The best proportion of this flocculent is TP （mg·L^-1） ： The amount of lime （mg）： Flocculent A （mg·L^-1） = 38：200：1, reducing the TP to 0.1mg·L^-1, reaching the primary discharging standard. Compared to the traditional phosphorous removal way, we improved the phosphorous removal rate by 20% -30%, the Cost of the process has been reduced by 10% - 20%. So it is of obvious economic and environmental benefits.
