对蔗渣浆采用过氧化氢强化的氧脱木素（Op）-螯合预处理（Q）-压力过氧化氢漂白（PO）的短序漂白，探讨了将蔗渣浆漂至82％ISO和用非硅过氧化氢漂白稳定剂代替硅酸钠用于过氧化氢漂白的可行性．研究表明，非硅过氧化氢稳定剂PP-1与PP-2耐高温、耐高压，可用于压力过氧化氢漂白．OP段氢氧化钠用量为2．0％（相对于绝干浆质量，下同）、过氧化氢用量为0．5％，PO段过氧化氢用量为3．0％、PP-1用量为0．1％、PP-2用量为0．5％时，蔗渣浆采用OPQPO流程漂白后，浆的白度可达到85％ISO．而且OPQPO从根本上消除了可吸附有机卤化物的产生；经测定，漂白废水属于可生物降解废水

A short bleaching sequence for bagasse pulp, which includes the oxygen delignification enhanced with hydrogen peroxide（ OP ）, the chelating pretreatment （Q） and the hydrogen peroxide bleaching with pressure （PO）,was investigated. The possibility of obtaining bleached pulp with a brightness of 82% ISO and substituting sodium silicate with non-silica stabilizer in the hydrogen peroxide bleaching was explored. The results indicate that （ 1 ） non-silica stabilizers PP-1 and PP-2 are both suitable for hydrogen peroxide bleaching owing to their resistance to high temperature and pressure ; （2） with a sodium hydroxide dosage of 2. 0% （ relative to oven dry pulp, the same below） and a hydrogen peroxide dosage of O. 5% in Op section, and with a hydrogen peroxide dosage of 3.0%, a PP-1 dosage of 0. 1% and a PP-2 dosage of 0. 5% in Po section, the bleached pulp is of a brightness of 85% ISO;and （3） as no adsorbable organic halogens are found in the OPQPO process, the bleaching effluent can be successfully degraded by organisms.
