以丙烯酸钠在N2和空气气氛下的热重红外联机热解试验为基础，在热态燃煤试验炉上，对丙烯酸钠有机废水在不同条件下的烟气脱硝机理进行了分析研究。结果表明，丙烯酸钠有机废水热解出具有还原性的中间产物，可以将NO还原为N2，从而实现脱硝。提高氧含量，丙烯酸钠热解的还原性中间产物被氧氧化，不利于NO的还原脱硝。适当升高温度，有利于H2、CO等还原性中间产物生成和脱硝，但同时促进了N2的氧化；在氧含量为4.1％，废水COD与烟气NO质量比为11.1，温度为1360 K，停留时间为0.82 s的条件下试验，达到最佳脱硝效率为37.6％。

The process of denitration by sodium acrylate wastewater and the mechanism of different factors affecting the process were tested on coal-fired furnace .The denitration mechanism of the organic wastewater was briefly analysed and the impacts of parameters such as temperature , oxygen content and the sodium acrylate content on the flue gas denitration process were tested .Thermogravimetric analysis and infrared spectroscopy were used to test the sodium acrylate pyrolysis process in N 2 and air atmosphere .The affecting mechanism of the temperature and oxygen content on denitration of sodium acrylate organic wastewater was studied .The result showed that intermediate products were produced during the sodium acrylate organic wastewater pyrolysis process .The intermediate products can remove NO in the flu gas by reducing NO to N 2 .The optimal denitration effect was achieved with denitration efficiency of 37 .6%, under the conditions of 4 .1% of oxygen content , 11 .1 of wastewater COD to gas NO mass ratio, the temperature at 1 360 K, and the residence time 0.82 s.The denitration efficiency increased if appropriately increasing the concentration of sodium acrylate .
