含油乳化废水处理的应用研究 总被引:1,自引:0,他引:1
简述了含油乳化废水常用的破乳工艺。以生产润滑油的某调合厂为实例,通过絮凝剂的筛选,采用复合型破乳剂聚合硫酸铝(PAS)作为絮凝剂进行化学破乳工艺试验,设计了破乳、气浮、活性炭吸附处理及附加条件的5种试验。结果表明,聚合硫酸铝与阴离子(非离子)复合型破乳剂能有效地对调合厂含油乳化废水进行破乳,每吨废水分别加500mL的聚合硫酸铝(浓度为10%)和500mL的阴离子PAM(浓度为0.1%),停留时间为5min,即能完成破乳及油水分离过程,废水处理药剂费用为0.25元/t左右,在原水COD2894mg/L时,COD去除率达到96.8%。经处理后的排放废水能够达到国家规定的排放标准。 相似文献

Salicylaldehyde Schiff base of amino-methylated polystyrene has been developed as a novel reagent for the removal of Fe(III)
from solutions. The selectivity of the metal ion uptake over a wide range of different concentrations of metal ion, effect
of pH, ligand concentration and the influence of other foreign ions were studied. A very good selectivity was achieved for
the removal of the ion. It was found that 0.01 g of the ligand was sufficient to achieve about 96% removal of the metal ion
in terms of concentration (ppm) from a 30 ppm solution in acidic pH. 相似文献
