摘　　要：研究了稻草亚铵浆的氧碱漂白、酸预处理和过氧化氢补充漂的三段漂白。结果表明,稻草亚铵浆经一段氧碱漂白后(浆浓10%,用碱量3%,氧压0.6MPa,温度80℃,时间80min),白度为55.2%ISO,经硫酸第二段预处理后(用量1.5%,温度65℃,时间40min),进行过氧化氢第三段补充漂白(浆浓12%,过氧化氢用量4%,氢氧化钠用量2%,温度85℃,时间80min),浆料白度达到66.4%ISO。This paper studied the TCF bleaching of rice straw ammonium sulfite pulping, which contains of oxygen-alkali bleaching, acid treatment and hydrogen peroxide bleaching. The result showed that the straw pulp （unbleached pulp had 43.3 %ISO brightness） could be bleached to 55.2 %ISO brightness after one stage oxygen -alkali bleaching （pulp consistency 10 %, NaOH 3 % , oxygen pressure 0.6MPa, temperature 80℃ and time 80min MgSO4 0.5 %）. After acid treatment （H2SO4 1. 5 %, temperature 65 ℃, time 40min）, the straw could be bleached to 66. 4 % ISO through hydrogen peroxide bleaching （pulp consistency12%, NaOH2 %, temperature 85℃ ,time 80min）.
