草浆造纸黑液资源化工艺研究

A Study on Resource Recycling Process Technology of Black-Liquor of Straw Pulping in Paper-Making

草浆造纸黑液的污染治理技术是国内水污染控制研究的热点。由于草浆黑液的特点不同于木浆造纸废水,因而其治理成本较大。系统分析了草浆黑液的特点,探讨了一种资源化治理工艺,该工艺的推广应用能在我国水污染控制领域发挥作用。

The technology of managing the pollution of black-liquor of straw pulping in paper-making is a hot point in native water pollution controlling research. Because the characteristic of black-liquor of straw pulping is different from wood pulping, so its controlling cost is bigger than that of wood pulping. This article analyses the characteristic of black-liquor of straw pulping and discusses a resource recycling process in controlling its pollution. The widely application of this process will do play an important role in water pollution control field.
