Abstract: Novel active oxygen and solid base method was used for bagasse cooking in this study to investigate the characteristics of pulp and waste liquor. The potential application of this kind of pulp in papermaking and the impact of the wastewater on environment were studied as well. The results indicated that the pulp yield is 44.74 %, the Kappa number is 21.82, the pulp visco-sity is 6.26 mPa·s and the whiteness is 34.21(ISO).While for the paper, the burst index , tensile index , tear index and folding strength were 2.18 mN·m2/g, 29.68 N·m/g, 9.16 mN·m2/g and 52 times, respectively. In addition, for the waste liquor, the pH value, CODcr, BOD5 and suspended solids of cooking waste liquor are 7.98, 4.165×104 mg/L, 1.2×104 mg/L and 6.18×104 mg/L, respectively.
