有机/无机复合絮凝剂处理印染废水的研究

本文利用壳聚糖和氯乙酸反应制备有机絮凝剂羧甲基壳聚糖,利用生产钛白粉的副产品七水硫酸亚铁制得的无机高分子絮凝剂聚合磷硫酸铁,将两者复配制得无机/有机复合絮凝剂。分别对酸性艳红、直接紫、还原深兰三种染料模拟印染废水进行处理,详细研究了两种絮凝剂的复配比例、pH、添加量对印染废水处理效果。色度去除率和COD去除效果最好,达...

The Research of Organic/inorganic composite flocculant in dyeing wastewater The determination of Aniline,nitrobenzene in Industrial wastewater

In this article,prepared by the reaction of chitosan and organic acid carboxymethyl chitosan flocculant 1],the use of production of titanium dioxide by-product of ferrous sulfate heptahydrate obtained phosphorus inorganic polymer flocculant polymer ferric sulfate,the two were re-preparation of inorganic / organic composite flocculants.Red for acidic,respectively,directly purple,deep blue restore simulated three dyes dyeing wastewater treatment,a detailed study of two flocculants compound ratio,pH,add the a...
