麦草制浆造纸黑液的处理新工艺研究

New Treatment Technology of Black Liquor in Straw Based Pulping and Papermaking

对麦草制浆造纸黑液的处理工艺进行了报道，在酸析时加入硫酸铝，木质素析出更加完全，混合絮凝能有效去除污染成份，为中小型造纸厂黑液的治理提供了新途径。

A new treatment technology of black liquor in straw based pulping and papermaking is introduced. Addition of aluminum sulfate during acidolysis , lignin is more completely precipitated and the pollutant is easily removed by mixed flocculation. This technology provides a new way on black liquor treatment for middle and small paper mill.
