| 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%。

| Abstract: | Three flocculation 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 flocculation system, 58% of COD_(Cr) was removed when the treatment was at pH about 9. |
