摘　　要：采用鼓泡法测试一定质量分数的H_2O_2和NaClO_2溶液在不同的温度和质量分数条件下氧化吸收剂对脱硝效率的影响,得出各自最优脱硝条件,最后与一定质量分数的KMnO_4溶液两两串联得出最优脱硝条件。结果表明:(1)NaClO_2的脱硝效率高于H_2O_2的脱硝效率。(2)在一定质量分数范围内,H_2O_2和NaClO_2的脱硝效率随质量分数的增加而增加,但超过临界质量分数后,脱硝效率降低。(3)NaClO_2与KMnO_4溶液串联,得到的脱硝效率最高。The bubbling method is applied to test the effect of oxide absorber on the denitration efficiency under the condition of different temperatures and concentrations when the H2O2 and NaClO2 solution is in a certain concentration,finding out their respectively optimal conditions of denitration and also the final optimal conditions of denitration after being two by two in series with KMnO4 that it has a certain concentration. The experimental results show that,the denitration efficiency of NaClO2 is higher than H2O2,the denitration efficiency of NaClO2 and H2O2 increases with the increase of concentration in a certain concentration range,but the denitration efficiency is lower when it exceeds the critical concentration,and the denitration efficiency is the highest when the concentration of NaClO2 and KMnO4 is in series.
