［摘要］研究了聚合氯化铝的盐基度、用量及混凝温度对造纸中段水处理效果的影响。结果表明，对于符合国家标准的聚合氯化铝，其不同的盐基度对造纸中段水的处理效果有较大的影响。对于河南武陟县西滑丰造纸厂选用的75%的PAC，当投药量(以废水量计)为0.6 g/L时，COD去除率达69%，SS去除率为84%，处理后的废水达到国家排放标准。

Abstract: The effect of the base saturability, the dosage and the temperature of coagulation of PAC on the grey water of paper industry has been studied. The result shows that: as far as the PAC in accordance with the GB standard is concerned, its specific base saturability has a greater effect on the grey water of paper industry. The treatment of the grey water of paper industry from Xihuafeng, Wuzhi, Henan province has been stated as follows: When the dosage of PAC with 75% of base saturability is 0.6 g/L water, the removal rate of COD is 69%, removal rate of SS is 84%, the treated wastewater can meet the requirement of the discharging standard
Key words: polyaluminium chloride; grey water of paper industry; base saturability
