摘　　要：对铁盐化学同步除磷进行了研究 ,通过试验比较了硫酸亚铁和氯化铁的除磷效果 ,前者的效果优于后者。并就污泥回流对除磷的影响进行了模拟试验 ,结果说明污泥回流可以节约药剂投加量。The iron salt synchronization dephosphorization was studied. The dephosphorization effects of ferrous sulfate and ferric chloride were compared, and the former's effect was better than that of the later. Moreover, a simulated experiment on the influence of the reflux sludge on the dephosphorization was carried out. The result indicates that the sludge reflux can save the medicaments.
