摘要
研究了不同碳氮比下常规反硝化及催化铁耦合生物反硝化效率以及N2O产生。结果表明,随着碳氮比降低,两组总氮去除率降低,N2O释放增加。但相比对照组,催化铁组有较高的硝氮转化率及N2O产生量。此外,N2O在C/N=1时仍能被完全降解。
The denitrification efficiency and nitrous oxide production during conventional biological denitrification and denitrification coupling with catalytic iron under different C/N ratio was studied. The results show that in both groups, the total nitrogen removal efficiency decreases while nitrous oxide production increases when C/N ratio becomes lower. But comparing control group, catalytic iron group has higher nitrate transforming efficiency and nitrous oxide emission. Futher more, the nitrous oxide could even be totally degraded when C/N was 1.
