造纸污泥回填剂原理

造纸污泥回填剂原理

发布日期:2017-12-12 作者:郑州华祥浆料 点击:

传统的处理工艺无法使造纸工业排放废水及污泥回收再利用,而且目前国内所普遍使用的碱式氯化铝和聚丙烯酰胺等传统药剂处理的造纸废水,出来的污泥易发黑、发臭,从而造成二次污染,使生态环境恶化及造成资源的浪费。因此研制来发投药量低、适应性强、絮凝效果好、废水能回用、造纸污泥必中彩票APP下载能回用抄纸的净水剂就成为亟待解决的问题。

(1)造纸污泥回填剂的合成技术路线及制备原理和方法

造纸回填剂是一种在聚合磷硫酸铁及聚合硫酸铝铁基础上合成的新型无机高分子净水剂。虽然造纸废水净水剂是在聚合硫酸铁基础上合成的,但由于磷酸根离子介入,使两者的性能和使用pH值范围有本质的不同,下面是合成造纸污泥回填剂的工艺条件简述。
