摘　　要：对吹脱法处理某高浓度氨氮废水进行了研究,考察了温度、pH值、气液比、原水浓度对吹脱试验的影响。结果表明,在最佳工艺条件下,废水的氨氮去除率超过99.31%。同时,比较不同酸吸收液对吹脱出气的吸收效果,找到最合适的酸吸收液。Based on the experiment of dealing with high concentrated ammonia nitrogen wastewater by blow-offmethod, the effect factors such as temperature, pH value, air/liquid volume ratio, initial wastewater concentration are analyzed. The result shows that removal rate of ammonia nitrogen can be above 99.31% in the optimum process conditions. At the same time, the effects of different acid absorption of blow-off gas were compared to find the most suitable acid absorption liquid.
