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。
The effects of PAC and Al2 (SO4) 2 · 18H2O on their oil removal were investigated experimentally. The experiment found that PAC and Al2 (SO4) 2 · 18H2O have certain synergistic effect, and there exists an optimal compounding ratio for a certain sewage system. At the same time, the effects of pH value, dosing concentration of coagulant and flocculation time on the flocculation effect were also investigated.
