阳离于高分子絮凝剂用于印刷油墨废水处理

Treatment of Printing Ink Wastewater with Cationic Polymer Flocculant

聚二甲二烯丙基氯化铵(P_(DMAAO))用于印刷油墨废水的处理,对共聚物中阳离子含量的选择、最佳投药剂量以及处理体系中温度等因素对处理效果的影响进行了研究.着重研究了絮凝剂的分子量和阳离子度对处理效果的影响.研究结果认为P_(DMDAAO)适用于印刷油墨废水的处理.

The cationic polymer flocculant based on dimethyl-diallyl ammonium chloride and other water-soluble monomer was used for treatment of printing ink waste-water. The influences of selection of cationic ! ion ratio, optimal quantity of flocculant and the temperature on the wastewater treatment effects were investigated, emphasis on the influences of molecular weight of flucculant and cationic ion ratio in copolymers on wastewater treatment effects. The reults showed that polydimethyl-diallyl-ammonium chloride and copolymers are useful for treatment of printing ink wastewater.
