摘    要:研制了一种高效混凝剂PACRES并将其用于印染废水处理中,处理效果优于聚合氯化铝(PAC),是一种去除印染废水色度的高效混凝剂。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。将它用于印染废水处理,可提高处理效果,使废水的色度去除率达90%以上,COD去除率达到65%以上,同时用量比PAC降低30%~50%。

关 键 词:稀土  聚合氯化铝  混凝剂  印染废水  色度去除率

Abstract:The paper introduces an effective coagulant and its application to the waste water of dying and printing. The coagulant is more effective to the decolority of the waste water than PAC. The new complex coagulant PACRES is a compound of basic solutions of polyaluminumchloride containing race earth and sulfur element. The application of race-earth-containing basic solutions of polyaluminumchloride to the waste water of dying and printing makes great effects of 90 percent of the decolority and 65 percent of the decreasing of CODc, with the amount of half or two-thirds of PAC.
Keywords:race earth  coagulants  PAC  waste water of dying and printing  percentage of the decolority
