摘　　要：使用过氧化氢在常压条件下对稻草亚铵法制浆废液进行氧化氨解改性以提高其有机氮含量,通过改变过氧化氢用量、反应温度、反应时间、氨水用量等,研究反应条件对该废液有机氮含量的影响。实验结果表明:过氧化氢氧化氨解改性后的废液有机氮含量为原废液的1.78倍;改性最优条件为过氧化氢10%、反应温度60℃、反应时间100min、氨水用量6%,并通过测定活性有机碳含量和红外光谱分析进一步证实了改性效果。Pulping waste liquor of rice straw with ammonium sulfite method is modified by hydrogen peroxide. The aim of the reaction is to increase the content of organic nitrogen. Optional reaction conditions are hydrogen peroxide, temperature, duration and ammonia. Results of the experiment show that the content of organic nitrogen of modification is 1.78 times than the primary one. Optimal reaction conditions are hydrogen peroxide 10%, temperature 60℃, time 100 min and ammonia 6%. The effects of the reaction are confirmed by the determination of active organic carbon and FTIR.
