化学破乳特性与高分子聚合物破乳 总被引:10,自引:0,他引:10
乳浊液中含有大量的油类和表面活性剂,并以微细的颗粒液珠高度分散在水中,具有相当的稳定性。因此,破乳是处理乳化液废水的关键之所在。以阴离子表面活性剂作乳化剂的O/W型乳化液为研究对象,通过试验,分析乳化液的浓度、乳化液的PH值等因素对破乳的影响。并比较了聚合硫酸铝与聚合硫酸铁的破乳效果,分析了聚合硫酸铁的破乳机理及特性。说明聚合硫酸铁是一种新型高效的破乳剂,值得广泛推广,以利于更经济有效地治理乳化液 相似文献

Demulsification of emulsified watsr-in-oll droplets was worked out with the employment of wetting coalescence mtsrials. Demulsification is carried out in conventional stirted-colunm and packed-column, Among the four kinds of natural fibers and two kinds of inorganic materials tested, natural fiber A, originated from wood shavings was found to give the best performance of demulsifica-tion. The demulaification efficiency can exceed 96.5% when demulsification conditions are optimized. The packed-column showed much better performance both in terms of demulsification efficiency and repeated use of the recovered oll phase for extracting cadmium in simulated wastewater. Operating variables governing the demuliifieation efficiencv were inventigated. 相似文献
