摘要
自行研制了新型聚合铝铁絮凝剂,并将其用于造纸废水的处理。絮凝剂的组分和用量对造纸废水的处理有明显影响。实验结果表明,该絮凝剂在用量为1.5～3.0ml的范围内,可以去除60%以上的COD,废水中悬浮物的去除率高于75%,色度去除率可以达到69%以上。
A new coagulant of poly-alumina iron was prepared and used to treat paper making wastewater.Compositions and dosage of the coagulant showed evident effect on treatment of paper making wastewater.Experimental results indicated that with 1.5～3.0ml of coagulant dosage,COD removal efficiency of the wastewater can reach more than 60%,and removal efficiency of its suspended solids and color were both above 75%and 69%,respectively.
