摘　　要：用不同浓度的COD炼化废水,通过对3种絮凝剂PACS、PAC和XF-102的复合絮凝效果比较,考察了温度和pH对絮凝效果的影响。絮凝后的水经Cu2+催化空气氧化,可以将COD去除率提高到60%以上。Through the comparison of the complex flocculation effect of PACS,PAC,XF-102 on refinery wastewater with different COD concentrations,the effect of temperature and pH on flocculation has been investigated.The removal rate of COD could be higher than 60% after being catalyzed by air oxidization in the presence of copper ions.

关 键 词：絮凝 空气氧化 化学需氧量
