摘　　要：制浆造纸厂固废绿泥,目前尚无很好的综合利用方法,普遍都是填埋、焚烧。各厂因制浆工艺、原料以及碱炉工况的差异,造成绿液固体悬浮物差异很大,故绿泥产生量相差几倍甚至几十倍。本文简要分析了国内化机浆黑液碱回收绿泥产生的原因、绿泥资源化处理方法及绿泥减量化的工艺措施。There is still no good comprehensive utilization method for solid waste green mud in pulp and paper mills,and it is generally landfilled and incinerated.Due to differences in the pulping process,raw materials,and operating conditions of the alkali furnace,the suspended solids of green liquor vary greatly among plants,so the amount of green mud produced varies several times or even dozens of times.This article briefly analyzes the causes of green mud produced in domestic chemi-mechanical black liquor alkali recovery,methods to green mud resource treatment and measures to green mud reduction.
