| 摘 要： | 以连续运行的生物活性炭(biological actived carbon,BAC)填料反应器为研究对象,与序批式活性污泥反应器(sequencing batch reactor,SBR)对比,考察了BAC的加入对不同C/N比废水同步硝化反硝化(simultaneous nitrification and denitrification,SND)脱氮效果的影响.在室温(15~27℃),初始溶解氧(dissolved oxygen,DO)质量浓度2~3 mg·L-1条件下,以甲醇做外加碳源,分别设置进水C/N比为3、5、8和10运行120个周期,比较两反应器的脱氮效果及稳定性.结果表明,C/N比由3依次升至5和8时BAC填料反应器脱氮效果优于SBR,TN平均去除率分别达44.88%、58.07%和66.64%.继续增大进水C/N至10,SBR发生污泥膨胀,而BAC反应器仍能保持63.65%的TN去除率.实验证明BAC在单一反应器内创造了多样的溶解氧环境,为SND创造了适宜的条件.BAC的加入减小了过量有机碳对硝化系统带来的影响,扩大了反应器的C/N比适用范围,增加了运行的稳定性,提高了有机物的脱氮容量,为高效脱氮提供了可能.
