Explosion method;  pulp filtrate;  Polysaccharides;  content determination;  Feeding trials

Based on the principle of non-chemical pulping technology of wheatgrass and explosion method, the polysaccharide content in the filtrate of wheatgrass pulp was tested and analyzed, and a livestock animal feed in line with local reality was developed, and comparative feeding was carried out. This technology can not only solve the problem of COD of papermaking wastewater and reduce pulp transportation costs, but also can be used for the preparation of industrial raw materials such as ethanol and gluformaldehyde.
