摘要：

某制药厂在生产乙胺碘呋酮时产生了一部分高浓度氨氮废水（NH3-N7200～7500mg/L）.通过实验室的静态吹脱试验，当pH为10～13,温度为30～50℃时，氨氮吹脱效率为703%～993%.通过比较，得出该废水最经济合理的吹脱pH为11,温度为40℃。在此最佳吹脱条件下，最合理的吹脱时间为2h,吹脱效率为96%.吹脱后的废水氨氮浓度大大降低，可以进入生化处理系统进行处理。

Abstract:

When a pharmaceutical factory was producing TMP, it produced some ammoniac wastewater with high concentration at the some time. The static state test of air stripping showed, when the pH between 10～13， the temperature between 30～50 ℃,the ammoniac removal rate of these tests is between 70.3%～99.3%. The best condition of these tests is pH 11, temperature 40 ℃. Under this best condition, the reasonable time of air stripping is 2 hours, the removal rate is 96%. The ammoniac concentration is low after air stripping, so it can enter the biochemical system to be treated continually.

Key words: ammoniac, air stripping, pH, temperature
