Abstract:
The effect of C/N ratio on kinetics of nitrite denitrification,as well as the corresponding N2O accumulation and reduction were investigated in a 3 L sequencing batch reactor. The initial 20 mg N·L-1 NO-2 -N was obtained by adding NaNO2. The C/N ratios 1.8,2.5,3.2 and 4.5 were reached by adding 0,0.05,0.1,0.2 ml ethanol respectively. The highest N2O accumulation was 333、200、245 and 256 μmol·L-1 for each C/N ratio. The nitrite reduction and N2O production rate increased with the increase of C/N ratio. The reduction rate of N2O was about 35— 摘要: 采用体积为3 L的SBR反应器,通过投加NaNO2的方式调节反硝化初始NO-2 -N为20 mg N·L-1,同时,投加0、0.05、0.1、0.2 ml乙醇调节初始碳氮比(C/N)分别为1.8、2.5
