摘　　要：采用烧杯搅拌实验法优化絮凝剂用量时步骤繁琐、周期长,提出通过测定Zeta电位优化絮凝剂用量方法,以大庆某油田采出污水为研究对象,得到加入不同质量浓度的絮凝剂后的Zeta电位与絮凝效果的关系.实验结果表明,无机絮凝剂和阳离子型有机高分子絮凝剂均能使油井采出污水悬浮颗粒表面Zeta电位向正方向移动;2种絮凝剂同时使用会降低絮凝剂用量,提高絮凝效果;Zeta电位值越接近于0,絮凝效果越好.When optimizing the dosage of flocculant by beaker-stirring experiment,its process is very numerous and time-consuming.So the optimization method of flocculant dosage by Zeta potential of the particles in sewage is established in this paper.For the sewage from one company of Daqing oilfield,the dosage of flocculant was optimized by measuring the relationship of Zeta potential and treatment effect of the sewage added flocculant at different concentration.It shows that both inorganic flocculant(polymeric aluminum chloride) and cationic organic macromolecule flocculant can cause Zeta potential shift toward positive value.Combining the two kinds of flocculants can decrease the total dosage of flocculants and improve flocculation effect.The closer to 0 Zeta potential is,the better the treatment effect will be.
