【摘要】 分别对PAC和Al2 (SO4 ) 2 ·18H2 O及其复配后的除油效果进行了实验研究。实验发现 ,PAC和Al2 (SO4 ) 2 ·18H2 O具有一定的协同效果 ,对一定的污水体系存在着一个最优的复配比值。同时还考察了pH值、混凝剂的投加浓度、絮凝时间对絮凝效果的影响。

【Abstract】 The effects of PAC, Al 2(SO 4) 2·18H 2O and their compound in flocculent process of oily waste water have been researched experimentally. Because of common ion effect the results showed that, PAC has cooperative effect with Al 2(SO 4) 2·18H 2O in flocculent process of oily waste water. The optimum ratio of PAC to Al 2(SO 4) 2·18H 2O and the optimum concentration of their compound in oily waste water and pH value are also been determined.
