| 摘 要： | 对微波技术处理高浓度氨氮废水进行研究,分别考察了pH值、微波作用时间、曝气与否、初始氨氮浓度对去除率的影响。研究结果表明:pH和微波作用时间是影响氨氮去除率的关键因素,曝气可增强氨氮的去除率效果;浓度为500 mg/L的氨氮废水,在pH为10,微波作用时间为4 min时,曝气去除效果较好,去除率可达81.7%。 |
| 关 键 词： | 微波辐射 氨氮废水 微波热效应 非热效应 |

| Abstract: | Treatment of wastewater containing ammonium-nitrogen using microwave was studied.Four factors including the initial pH value,MW radiation time,aeration and initial concentration of ammonia nitrogen were investigated.Results showed that pH and MW radiation time were of most importance and aeration can enhance the removal of ammonia nitrogen to some extent.For ammonia nitrogen with the concentration of 500 mg/L,the optimal conditions were obtained when the pH is 10 and when the MW radiation time is 4 minutes.... |
| Keywords: | microwave radiation ammonium-nitrogen wastewater MW thermal effect non-thermal effect |
