摘　　要：本文根据絮凝基本理论知识,以我国南方某造纸厂造纸车间DAF出口处的过程水作为试验原水进行了絮凝预处理试验。结果表明:在一定试验条件下,当混合药剂(PAC+PAM)的投加量为(2+0.5)mg/L时,对浊度较低的造纸过程水,其浊度去除率达到43.65％以上,絮凝处理后的出水浊度在12NTU左右,且处理时原水的pH值不需要调整,为后续的处理打下了良好基础。According to coagulation theory, the coagulating pretreatment of the process water in a newsprint mill was carried out. The results show that: when the dosage of (PAC+PAM) was (2+0.5) mg/L, turbidity removal rate of process-water was over 43.65% at the suitable experiment conditions. Furthermore, the pH of untreated water was not needed to be adjusted.
