摘　　要：研究了稻草碱性K2SO3-AQ体系蒸煮优化工艺,结果表明最佳蒸煮条件为:10%总碱量,0.8的碱比,0.2%AQ,最高温度160℃和保温时间120 min。所制得纸浆的卡伯值14.5,粗浆得率53.8%,细浆得率42.5%,本体系较传统钠基盐蒸煮的优势是其经济的回收系统,一种新型的生态循环将在农作物和造纸厂之间形成。A pulping method using alkaline K2SO3-AQ system as cooking liquor to digest rice straw was studied in this paper. The optimal cooking conditions were 10 % of total alkali, 0. 8 of alkali ratio, 0.2 % of AQ, 160 ℃ of maximum temperature and 120 min of cooking time. Pulp yield reached 53.8 %, screened pulp yield reached 42.5 %, and Kappa number was 14.5. It looks promising to use effluents of cooking into fertilizer because it contains rich nutrition such as potassium and lignin. A new ecological cycling maybe set up between paper industry and farming.
