| 摘 要： | 以NH4+浓度为5000mg/L的废水为研究对象，考察了真空脱氨效果，结果表明pH与夹套水温是主要影响因素，当pH为12,夹套水温为50℃,真空度为7.9kPa，进料流速为20mL/min的较缓和条件下，单次实验氨去除率可达87.2%，连续实验平均脱氨率为86.2%。

| Abstract: | The effects of test conditions on the efficiency of ammonia removal from wastewater with high ammonia content were studied by vacuum desorption method. Results showed that the pH value of wastewater and the temperature of jacket heating water were the main influential factors. When treating wastewater with a NH3 content of 5 000 mg/L using a vacuum column packed with 4 mm θ stainless steel packing, under the conditions of a wastewater pH value of 12, a jacket-water temperature of 50℃, a vacuum degree of 7.9 kPa, a feed rate of 20 mL/min, the once-through removal rate of ammonia reached 87.2% and an average ammonia removal rate of 86.2% was obtained from continuous experiments. |
