酸性尿素水溶液处理导弹氧化剂废水中氮氧化物

ON THE ACIDITY URATUNIAN DISPOSAL OF THE NO_x IN MISSILE OXIDANT WASTEWATER

采用理论分析和实验两种方法对酸性尿素水溶液处理导弹氧化剂废水中 NOX进行了研究。讨论了 NO2 的转化率与尿素浓度的关系。实验证明 ,该方法快速高效 ,反应的适宜温度为 30℃ ,用 7%的尿素水溶液处理含 NO2 941 9.8mg/ m3的废水 ,1 0 s的去除率可达 99.5%。

In the present paper method of NO x disposal in missile's oxidant wastewater by using acidity uratunian liquid is studied. A new method of NO x disposal is presented with the methods of experiment research and theoretical analysis. The relationship between the transformation efficiency of NO 2 and the concentration of uratunian is discussed. The results gained in this paper shows that the reaction is positive as well as effective. The NO 2(9 419.8 mg/m 3) in the wastewater can be disposed by using 7% of uratunia with a disposal rate as high as 99.5% at ten second. The results indicate that the process should be done at a favorable temperature such as 30 ℃. The theoretical analysis also suggests that the favorable temperature is very important for absorbing NO x . At high temperature, NO 2 is easier to volatilize from the solution, which would lead to the air pollution.
