  • 摘要: 采用间歇实验研究联氨(N2H4)对好氧氨氧化和亚硝酸盐氧化的抑制类型。结果表明,N2H4对好氧氨氧化及对亚硝酸盐氧化抑制类型分别为竞争性和非竞争性抑制。N2H4对亚硝酸盐氧化的抑制大于其对好氧氨氧化的抑制。在较低氨氮(NH4+-N)浓度时,N2H4对于好氧氨氧化的抑制作用随N2H4浓度增加而增强;但在较高NH4+-N浓度时,NH4+-N基质能抵消N2H4对氨氧化的部分抑制作用。N2H4对于亚硝酸盐氧化的抑制作用随N2H4浓度增加而不断增强。
    Abstract: Inhibition types of hydrazine (N2H4) to aerobic ammonia oxidation and nitrite oxidation were studied via batch tests. The results demonstrated that the inhibition of N2H4 to aerobic ammonia oxidation and nitrite oxidation was competitive and noncompetitive, respectively. The inhibitive effect of N2H4 on nitrite oxidation was stronger than that on ammonia oxidation. Under low ammonium-nitrogen (NH4+-N) concentration conditions, the inhibitive effect of N2H4 on ammonia oxidation increased with increasing N2H4 concentration; however, high NH4+-N concentration could counteract partially the inhibitive effect of N2H4 on ammonia oxidation. The inhibitive effect of N2H4 on nitrite oxidation continuously increased with increasing N2H4 concentration.
