摘　　要：为解决常用絮凝剂存在低效高耗、二次污染等问题,提出使用有机高分子絮凝剂处理含油废水.通过有机单体丙烯酰胺、丙烯酸、2-丙烯酰胺基-2-甲基丙烷磺酸的水溶液聚合和反相乳液聚合,经红外光谱的结构验证和对含油废水的实际处理,确定了用反相乳液聚合法合成的絮凝剂具有较好的絮凝效果.考察了pH值、絮凝剂的投加量、水温等因素对絮凝效果的影响.结果表明,在常温下絮凝剂投加量为230mg/L,pH值为6时可以取得最佳的絮凝效果,其对废水中油类的去除率可达90.1%.To solve the problems existed in the common flocculant during oily wastewater treatment,such as low efficient,high cost and secondary pollution,a kind of organic polymer flocculant was adopted to deal with the oily wastewater.The flocculant were prepared by acrylamide,acrylic acid,2-acrylamido-2-methyl propane sulfonic acid through aqueous solution polymerization and inverse emulsion polymerization.The flocculant prepared by inverse emulsion polymerization has better flocculation effect according to the structure verification by infrared spectra and the actual treatment effect analysis of oily wastewater.The effects of pH,the amount of flocculant and the temperature of water on the flocculants efficiency were investigated.The results show that the best flocculating rate reaches to 90.1% under room temperature when the flocculant dosage is 230mg/L and pH value is 6.
