摘　　要：以冷轧乳化液废水为研究对象,通过十六烷基三甲基氯化铵与氯代十六烷基吡啶按质量2∶1加入到无水乙醇中制成饱和溶液为破乳剂,改性膨润土为絮凝剂,采用破乳-絮凝的复合处理工艺,研究其对乳化液废水处理效果的影响因素。研究结果表明,在100mL乳化液废水中加入2mL破乳剂,调节pH值至8.2,温度30℃,搅拌2min后,加入改性膨润土8g,经分散絮凝,乳化液废水清澈透明,CODCr去除率可达99.4%,浊度指数可达97.1%。Taking the emulsion waste water as the research object. Through the hexadecyl trimethylammoniumchloride and cetyl pyridinium chloride by the quality of 2：1 into anhydrous ethanol to produce saturated solution as demulsifiers, modified bentonite as flocculant, the demulsification and flocculation of composite process to study its effect on emulsion waste water treatment effect factors. Research results show that, Join demulsifier 2 mL and modified bentonite 8g to the 100mL emulsion waste water, Control the pH=8.2, temperature 30℃, the water turn to clear and transparent through floeeulation, CODcx removal can reach to 99.4%, turbidity index reach to 97.1%.
