| Abstract:This paper addressed the experiment process of bio-enzymes application in wheat straw NS pulping. Results show that, using 1.5% bio-enzymes (on the oven-dried raw material) to take place of 30%~40% ammonium sulfite could produce the pulp with similar Kappa number and largely reduced the residual ammonium in blowing, it could reduce the corrosion of the digester, the tank, and the pipeline as well as reduce the ammonia nitrogen content of the effluent. |
