Abstract

Abstract:

The comparison of the effect of flocculants PAC、PFS、PFAC with that of a new type of complex flocculant on the advanced treatment of coking wastewater from iron and steel plants has been made. The results show that the new complex flocculant is not only the least in dosage, but also is superior to any other flocculants in the removal rates of COD and turbidity. Moreover, the mechanismof flocculation is discussed preliminarily.

Key words: coking wastewater, flocculation, complex flocculant

摘要：

对比研究了PAC、PFS和PFAC、新型复合絮凝剂深度处理钢铁厂焦化废水絮凝效果。结果表明新型复合絮凝剂不仅用量最小,而且其除COD、浊度等的效果均好于其他絮凝剂,同时对其絮凝机理进行了初步探讨。
