燃煤电厂末端废水氨氮分析方法探讨

Discussion on Analytical Method of Ammonia Nitrogen in Terminal Wastewater of Coal-fired Power Plant

氨氮是判断水体污染程度的重要指标之一。新的环保形势对燃煤电厂末端废水氨氮分析技术提出了新的要求。本文重点总结了常见水体氨氮分析方法,从准确性、时效性、抗干扰性、便携性、经济性等方面阐述了各方法的特点,并分析了其用于燃煤电厂末端废水氨氮浓度检测时的利弊。利用仪器自动化与联用技术对旧方法进行改进,以及开发准确便捷、绿色环保的新氨氮检测手段,成为当下研究的热点。

Ammonia nitrogen is one of the important indicators to judge the degree of water pollution. The new situation of environmental protection puts forward new requirements for ammonia nitrogen analysis technology of terminal wastewater in coal-fired power plants. This paper summarizes the common methods of ammonia nitrogen analysis in water, and expounds the characteristics of these methods from the aspects of accuracy, timeliness, anti-interference, portability and economy, and analyzes the advantages and disadvantages of these methods in the detection of ammonia nitrogen concentration in terminal wastewater of coal-fired power plants. The improvement of the old methods by using instrument automation and hyphenated technology and the development of accurate, convenient, green and environmental protection new ammonia nitrogen detection methods have become a hot spot of current research.
