摘要
介绍了采用酸析絮凝、聚合氯化铝与聚丙烯酰胺(PAC-CPAM)絮凝、聚硫氯化铝与聚丙烯酰胺(PACS-CPAM)絮凝处理双螺旋挤压法制浆废液。实验发现,该废液不适合采用PAC-CPAM絮凝;采用酸析絮凝效果较好;采用PACS-CPAM絮凝效果最好,且CODCr的去除率可以达到58%。
Three floeculation systems, acid precipitation, PAC-CPAM, and PACS-CPAM were introduced to treat the waste liquor from twin-screw extrusion pulping respectively. It was found that PAC-CPAM system had little effect on this kind of wastewater, and the effect of acid precipitation was better, and PACS-CPAM system was the most effective one among the three floceulation system, 58% of CODCr was removed when the treatment was at pH about 9.
