摘要：
新型稀土复合混凝剂PACRES是一种以聚合氯化铝为主要成分,并含有稀土、硫等元素的复合混凝剂。将它应用于印染废水处理,可改善处理效果,使废水的色度和CODCr达到较高的去除率,同时用量比PAC降低。

Abstract:
The new complex coagulant PACRES mainly consists of poly aluminumchloride, containing race earth and sulfur element.The application of this coagulant to the wastew ater of dying and printing has greater effects. The removal rates of chromaticity and CODCr are higher, and the amount of PACRES is less than PAC.
