摘　　要：提出一种以NaOH为吸收剂的脱硫脱硝方法,脱硫后的Na_2SO_4电解,一极电解生产NaOH循环使用,另一极产生稀硫酸可作为循环水酸化,同时释放出氢气和氧气,氢气储存用作化工原料,氧气经过电晕成臭氧用于氧化NO成NO_2,再溶于水脱除,实现脱硫脱硝一体化和资源化,最后分析了该方法的可行性和经济性。NaOH was presented as absorber, and Na2SO4 was electrolysised after the removal of sulfur. NaOH was re- cycled as electrolytic production in a ploe. Dilute sulpburic acid which was produced in another pole was used as recy- cled water acidification, releasing hydrogen and oxygen. Hydrogen was storaged for chemical raw materials preparing. O2 was coronaed into O3 , which oxidated NO into NO2 that could be removed after soluble in water. Meanwhile the fea- sibility and economy were analyzed.
