CONTROL STRATEGY OF SUBSEQUENT CARBON SOURCE IN ANAMMOX-MFC SYSTEM FOR ENHANCEMENT NITROGEN REMOVAL AND POWER GENERATION

  • 摘要: 考察添加后续碳源的厌氧氨氧化微生物燃料电池(ANAMMOX-MFC)高效脱氮产电运行的稳定性,采用高通量测序及KEGG功能酶预测对微生物群落结构及功能基因的变化进行表征。结果表明:系统可以连续稳定运行60 d,TN去除率稳定在96%以上,连续运行最大输出电压为800 mV左右。添加适当浓度的乙酸钠,可增高污泥中发酵菌Enterococcus、反硝化产电菌Pseudomonas、Thauera的相对丰度进而有效促进产电。但是过度水解酸化会抑制AnAOB活性。第68~104天,出水NH4+-N浓度升高,TN去除率下降至90%左右,通过停加乙酸钠TN去除率恢复至95%以上。ANAMMOX-MFC系统出水NH4+-N浓度可作为后续碳源停加的"调控信号",使得脱氮产电系统稳定高效运行,为厌氧氨氧化与微生物燃料电池脱氮产电的技术结合提供了很好的理论依据,具有一定的工程指导意义。
