摘要
利用微电泳技术对不同条件下乳化油废水的动电电位进行了测定,以了解油珠外表面所带电荷情况,为除油处理提供理论依据。试验结果表明,常温25℃下,水体的pH值对油珠表面的Zeta电位有显著影响;随着静置时间的增长,油珠的平均粒径增加且影响油珠的Zeta电位;电解质的加入对油珠的Zeta电位影响明显。
In order to know the the surface charge properties of the oil droplet of the emulsified oil wastewater,the electrokinetic potential of the said kind of wastewater under different conditions was determined by microelectrophoresis,and the study provided theory basis for oil removal.The results of the test showed that,the Zeta potential of the oil droplet surface was significantly affected by pH value when the temperature was 25 ℃;with the standing time increasing,the oil droplet size increased,and could affect Zeta potential;besides,the influence of electrolyte on Zeta potential of the oil droplet was also obvious.
