摘　　要：研究采用物理化学法对造纸白水中含细小纤维、无机填料的悬浮物进行处理试验,造纸白水被絮凝剂处理后CODCr、浊度去除率明显,通过对比聚合碱式氯化铝(PAC)、聚硅铝铁(PSAF)、聚硅硫酸铝(PASS)3种不同的絮凝剂与助凝剂PAM配合处理造纸白水,发现PASS絮凝效果最佳。研究表明,PASS与PAM配合处理白水的最佳条件:PASS100mg/L、PAM为2mg/L、pH=7.0,在最佳絮凝条件下,CODCr、浊度的去除率分别为92.8%、98.0%。The suspended solids （including tiny fibers and inorganic stuffing have been treated by physico-chemical process. After the paper-making ） in paper-making white wastewater white wastewater is treated with flocculant,the removal rates of CODCr and turbidity are obvious. The three kinds of flocculants： PAC,PSAF and PASS, with coagulant aids PAM are contrasted respectively in treating the paper-making wastewater. It is found that the flocculation effect of PASS is the best. The results show that the optimum conditions of using PASS and PAM cooperatively for treating the white wastewater are as follows： PASS dosage is 100 mg/L, PAM dosage is 2 mg/L, and pH=7.0. Under the best flocculation conditions, the removal rates of CODCr and turbidity are 92.8%, 98.0%, respectively.
