摘　　要：为了强化超声吹脱处理的作用与功能,研究加入促脱剂后的效果.通过实验选取一类低分子的有机溶剂与表面活性剂进行复配,探究对氨氮的去除率并与酯类复配的效果作比较.最终以AOS:乙酸乙酯的质量比为4:3为最佳脱氮剂.该方法处理高浓度工业氨氮废水具有去除效率高,材料、运行费用低,工艺操作简单等优势.此外,在实验过程中还发现,投加促脱剂在运行周期中可使设备的耐磨防腐性更优.在超声吹脱法-吸附的基础上投加促脱剂来减少氨氮污染排放的方法是切实可行的,且成本更低,经济效益、生态效益更好.In order to strengthen the function and function of ultrasonic stripping treatment,this experiment studied the effect of adding stripping promoter.Through experiments,a kind of low molecular organic solvent was selected and compounded with surfactant to explore the removal rate of ammonia nitrogen and compare with the effect of compounding with esters.Finally,the mass ratio of AOS to ethyl acetate is 4∶3 as the best denitrogenation agent.The method for treating high-concentration industrial ammonia nitrogen wastewater has the advantages of high removal efficiency,low material and operation cost,simple process operation and the like.In addition,it is also found in the experiment that the addition of stripping accelerator can make the equipment more wear-resistant and corrosion-resistant.It is feasible to add stripping promoter to reduce ammonia nitrogen pollution emission based on ultrasonic stripping-adsorption,and the requirement of treatment environment is lower than that of pure process treatment,which is more economical and environment-friendly.
