摘要
综述了干法脱硝、湿法脱硝、微生物法和化学吸收-生物还原法脱除烟气中氮氧化物的原理、技术特点和存在的问题。指出:化学吸收-生物还原法是未来脱除烟气中氮氧化物的主要研究方向之一,可通过提高NO在水中的溶解性,利用微生物去除氮氧化物,力争将其从实验室研究推广至工业应用。
The principles,technical characteristics and existing problems of the removal of nitrogen oxides from flue gas by dry denitrification,wet denitrification,microbial method and chemical absorption-biological reduction method are reviewed.It is pointed out that the chemical absorption-biological reduction method is one of the main research directions to remove nitrogen oxides from flue gas in the future.By improving the solubility of NO in water and using microorganisms to remove NOx,the chemical absorption-biological reduction method will be strived to extended from laboratory research to industrial application.
