基于电化学法的火电厂氮氨废水资源化处理研究

Study on recycling of ammonia and ammonia wastewater from power plant based on electrochemical method

氮氨废水直接排放易形成水体富营养化污染,如采用再生水直接回用手段时,水中含有的氮氨会促进微生物的繁殖从而形成生物污垢,以至于堵塞管道。本文分析了燃煤电厂氮氨废水的主要来源,从电化学法处理氨氮废水入手,研究电解处理反渗透氨氮废水的机理和影响因素,讨论了燃煤电厂氮氨废水资源化处理思路,为燃煤电厂氨氮废水资源化处理技术路线提供了参考。

Ammonia-ammonia wastewater is easy to form eutrophication when it is directly discharged.If the reclaimed water is recycled directly,the ammonia nitrogen in the water will promote the multiplication of microorganisms to form bio-fouling so as to block the pipeline.This paper analyzes the main sources of nitrogen and ammonia wastewater from coal-fired power plants,starting with the electrochemical treatment of ammonia-nitrogen wastewater,studying the mechanism and influencing factors of electrolytic treatment of ammonia-nitrogen wastewater,discusses the resource treatment of nitrogen and ammonia wastewater from coal-fired power plant,Ammonia nitrogen wastewater treatment plant resource-processing technology provides a reference.
