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
