| 摘 要： | 在拉西环填料塔内，采用空气吹脱法处理模拟废水中的氨氮。按F—HZ—HJ—SZ-0016标准测定模拟废水中氨氮质量浓度。通过实验考察了模拟废水pH值、空气流量、废水温度对氨氮吹脱效率的影响，确定了适宜的操作条件为：pH值13，空气流量150L／min，温度60℃。在上述条件下，氨氮吹脱效率达87．5％。

| Abstract: | The ammonia nitrogen in simulated wastewater is removed by air blowing stripping in a rashig-ring packed tower. Nitrogen concentration value is determined according to industry-standard F-HZ-HJ-SZ-0016.The influence of pH,airflow rates and wastewater temperatures on the stripping efficiency of ammonia nitrogen is investigated.The suitable operating conditions are determined as pH value of 13,air flow rate of 150 L/min,wastewater temperatures of 60℃.Under the above conditions,the stripping efficiency of 87.5%is obtained. |
