复合絮凝剂在印染废水处理中的应用分析

Application Analysis of Compound Flocculant in Printing and Dyeing Wastewater Treatment

复合絮凝剂在污水处理中扮演着十分重要的角色。因此,本文对复合絮凝剂在印染废水处理中的应用及作用机理进行了简要综述。同时通过综合对比处理效率、成本、环境损益等,为污水处理过程中复合型絮凝剂的选择提供参考依据。研究表明:低浓度有机印染废水多采用无机-无机复合絮凝剂进行处理,高浓度有机印染废水多采用无机-有机复合絮凝剂进行处理,高有机浓度、高浊度、及有特殊气味的印染废水则多采用有机-有机复合絮凝剂进行处理。

Composite flocculants play a very important role in sewage treatment. Therefore, this article briefly summarizes the application and mechanism of composite flocculants in the treatment of printing and dyeing wastewater. At the same time, through comprehensive comparison of treatment efficiency, cost,environmental gains and losses, etc., it provides a reference for the selection of composite flocculants in the sewage treatment process. Research shows that low-concentration organic printing and dyeing wastewater is mostly treated with inorganic-inorganic composite flocculants;high-concentration organic printing and dyeing wastewater is mostly treated with inorganic-organic composite flocculants;printing and dyeing wastewater with high organic concentration, high turbidity,and special smell Mostly use organic-organic composite flocculant for treatment.
