摘要
目的 研究梯恩梯(TNT)水溶液在臭氧紫外氧化工艺下的降解特性方法 通过实验,测定不同氧化条件下TNT降解过程中的TNT、三硝基化合物、臭氧等相关物质的浓度变化结果与结论 单独臭氧氧化对TNT的降解作用小;臭氧紫外联合氧化作用对TNT降解效果明显;碱性环境对臭氧紫外氧化法降解TNT的促进作用不大经臭氧紫外氧化处理后,TNT水溶液中仍残存一定量的三硝基化合物,当其质量分数下降到25以后变化非常缓慢从经济角度出发。
Aim To study the degradation of TNT in water by ozone ultraviolet advanced oxidation process (O 3+UV). Methods The concentration changes of various compounds such as TNT, trinitroaromatic compounds, O 3, etc. were investigated by experiments. Results and Conclusion TNT can be degraded more faster by combining O 3 with UV radiation while very slowly by only using O 3. A high pH does not improve the removal efficiency of O 3+UV process significantly. There still exist some trinitroaromatic compounds in the solution after TNT being processed, and they will reduce slowly after the mass fraction is less than 25%. The O 3+UV process is not suitable for the final treatment of trinitroaromatic compounds.
