EFFECT OF DIFFERENT CARBON SOURCES ON N2O RELEASE IN DENITRIFICATION PROCESS OF A SBR REACTOR

  • 摘要: 试验使用SBR反应器,采用乙酸钠、乙醇、葡萄糖和蔗糖4种常用的外加有机碳源,对反硝化反应中N2O释放过程进行研究。结果表明:4种碳源条件下,N2O积累量均呈先升高后降低最后保持稳定的趋势。N2O最大积累量分别为1.59,1.25,5.43,0.66 mg/L,最大转化率分别为1.61%、1.36%、5.44%和0.67%;最终积累量分别为1.02,0.67,3.12,0.49 mg/L,最终转化率分别为1.04%、0.73%、3.13%和0.50%。N2O释放量及转化率顺序均为葡萄糖>乙酸钠>乙醇>蔗糖。游离亚硝酸抑制、不同反硝化酶的电子竞争和微生物群落结构差异均是影响N2O释放的因素。
