摘要：
Hemicellulose is one of two major organic components in pulping spent liquor, and the recovery of hemicellulose from spent liquors has been satisfactorily solved. Lignosulfonates which has to be removed before Modified Hemicellulose (MH) can be extracted from the magnesium bisulfite pulping effluent of reed. Gas chromatography and infrared spectrometer studies reveal that extracted MH is mainly composed of arabinose and xylose with some glucose, a little galactose and mannose. With the magnesium bisulfite pulping effluent of reed treated, the removal rates of COD will finally be able to reach 94.4%.
