摘要: 本文以合成氨工序高氨氮废水作为研究对象，采用高级氧化法作为处理工艺，研究其降解反应特性，考察了工艺的主要操作条件，如反应压力、反应温度、反应停留时间、氧化剂用量等对废水处理效果的影响，在充足的氧化剂添加条件下，湿式氧化具有良好的处理效果，得到了最佳的反应条件：反应温度305℃、压力为14 MPa、氧化剂用量200 mg/L、反应停留时间为9 min，此时COD去除率为81.6%。
Abstract: In this paper, high ammonia nitrogen wastewater was used as the research object in the ammonia process. The advanced oxidation method was used as the treatment process to study the degrada-tion reaction characteristics. The main operating conditions of the process, such as reaction pres-sure, reaction temperature, reaction residence time and oxidant dosage, were investigated. The effect of wastewater treatment and wet oxidation has good treatment effect under sufficient oxidant addition conditions, and the best reaction conditions are obtained: reaction temperature 305˚C, pressure 14 MPa, oxidant dosage 200 mg/L, residence time was 9 min, and the COD removal rate was 81.6%.
