A novel epichlorohydrin-dimethylamine-methenamine quaternary ammonium salt cationic modified flocculant (HMTA) was synthesized from epichlorohydrin and dimethylamine as main raw materials. The flocculant (HMTA) showed better performance in the treatment of the Liaohe oilfield wastewater. Influences of the flocculant dosage and temperature on the flocculation performance of the flocculant (HMTA) were investigated. With the optimum temperature of 45 ℃ and the optimum dosage of flocculant of 20 mg/L, turbidity removal rate of 98.1% and oil removal rate of 35.1% are achieved. The infrared spectroscopy and nuclear magnetic resonance spectroscopy results illuminated that the methenamine acted as the crosslinking agent in the polymer and improved the flocculation performance of the epichlorohydrin and polyamine flocculant. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书附件1附件1 -->
