微波辐照处理高浓度氨氮废水的研究进展

Research progress in the microwave radiation for treating highly concentrated ammonia nitrogen wastewater

近年来,氨氮已成为影响我国地表水水环境质量的首要指标。"十二五"期间,氨氮是污染物控制的重点。采用微波技术处理高浓度氨氮废水具有明显效果。简要评述了高浓度氨氮废水的处理方法,介绍了微波加热原理,重点总结了各种微波技术处理高浓度氨氮废水的研究现状及其主要影响因素。指出需进一步研究机理、催化剂和成套设备研发等方面,以期早日实现工业化应用。

In recent years,ammonia nitrogen has become the leading indicator which affects the water environment quality of surface water in China. During the “Twelfth Five-Year Plan”period,ammonia nitrogen is the key point of pollutant to be controlled. Applying microwave radiation technique to the treatment of highly concentrated ammonia nitrogen wastewater has obtained remarkable results. The method for treating highly concentrated ammonia nitrogen wastewater are briefly evaluated and reviewed. The heating principles of microwave radiation are introduced ,and the current research status and principal influence factors of various microwave radiation techniques used for removing ammonia nitrogen from wastewater are emphatically summarized. It is suggested that its mechanism ,catalysts and the research and development of outfits should be studied further ,so as to realize the industrialization of it soon.
