摘要:为了满足高炉煤气洗涤废水循环使用的需要,采用聚合氯化铝与聚丙烯酰胺复配处理高炉煤气洗涤废水,探索了其最佳工艺条件,并比较了固、液体聚合氯化铝的性能.结果表明,液体聚合氯化铝的絮凝性能优于固体的,且与聚丙烯酰胺具有更好的配伍性能;液体聚合氯化铝的投加量小,复配处理效果更好.

Abstract: In order to meet the requirement of recycling use of blast furnace gas washing wastewater,the complex coagulant of Polyaluminium Chloride (PAC) and Polyscrylamide (PAM) were used to treat this wastewater.The optimum condition of treatment was explored.Also,the flocculation performances of the solid PAC and liquid PAC were compared.The results showed that the flocculation ability of liquid PAC is better than that of solid PAC,and the compatibility of liquid PAC with PAM is also better than that of solid PAC;the liquid PAC has the advantages of low dosage and better effect in complex treatment test.

Key words: Polyaluminium Chloride, Polyscrylamidecomplex treatment, blast furnace gas washing wastewater, industrial test
