摘要:

探讨了造纸黑液经酸化预处理沉淀后,再用四种高分子絮凝剂进行絮凝处理,通过絮凝条件试验,优选出了最佳絮凝剂及其适宜的pH值、药剂投量、搅拌时间、澄清时间等最佳絮凝条件,使废水中CODCr及色度达到较高的去除率。

关键词: 高分子絮凝剂, 造纸黑液, 絮凝条件

Abstract:

The flocculant treatment method of effluent in paper making blacklye of acidifying pretreatment by using four polymeric flocculant shave been studied.Through flocculating condition experiment,optimum flocculant and optimum flocculating conditions,such as pH value,quantity of the flocculant added,stirring time,deposit time have been made.Thevremoval rates of the COD Cr and colorityare higher.

Key words: polymeric flocculants, paper making blacklye, flocculating condition
