摘要
通过对某炼油厂炼油污水的研究,对照实验数据分析发现,PAC/CHI复配絮凝剂与PAC/PAM复配絮凝剂相比,其最佳搅拌时间为10min,最佳沉降时间为10min,最佳pH值为7.0,COD去除率高达70.8mg/L。
By making a careful study of the refinery waste water of a certain refinery factory and studying the experimental data, it is found that compared with PAC/PAM Composite flocculant, PAC/CHI composite flocculant has more advantages. It will be the best to be mixed and sedimentated for ten minutes respectively, with the highest PH value of 7 and COD removal rate as high as 70.8 mg/L.
