摘　　要：对硫酸盐竹浆的漂白工艺条件的研究结果表明,竹浆D_0(EOP)D_1漂白的优化工艺为:D_0段终点pH值在2.4至3.0之间,EOP段反应温度为70℃,H_2O_2用量为4kg/t,终点pH值为11.8左右,D_1段的终点pH值在3.8左右。在此优化条件下,当总有效氯用量为45kg/t时,纸浆的白度可以达到84.1%ISO,粘度为922ml/g,返黄值为0.89,同时优化后的D_0(EOP)D_1漂白浆具有很好的强度。The findings of technological conditions of sulfate bamboo pulp bleaching show that the optimized technology for bamboo pulp D0（EOP） D1 bleaching is： the final pH between 2.4 to 3.0; the reaction temperature of EOP stage 70℃, the H2O2 charge is 4kg/t, the final pH value, about 11.8; the final pH value of D1 stage, about 3.8. Under this optimized condition, when the total active chlorine charge is 45 kg/t, the brightness of the pulp can reach 84.1%ISO, viscosity 922ml/g, and the color reversion value 0.89 and the D0（EOP） D1 bleached pulp has excellent strength properties.
