　　研究了微好氧时间对低碳源污水脱氮的影响。结果表明，微好氧时间对低碳源污水COD去除效果影响不大，但对系统硝化和反硝化效果有很大影响。当工况为厌氧2h/微好氧7h时，氨氮去除率为96．9％；出水亚硝态氮质量浓度没有积累现象，仅为0．116 m g/L ；总氮去除率最高，达到了47．3％。微好氧时间过长或过短都会降低系统的硝化效果和反硝化效果。

The effect of micro-aerobic time on nitrogen removal efficiency in low carbon source sewage was evalua-ted .Results showed that micro-aerobic time had no obvious effect on COD removal efficiency ,but had a significant effect on nitrification and denitrification efficiency of the system .Ammonium nitrogen removal rate was up to 96.9% under the condition of 2h anaerobic process and 7h aerobic process ;The concentration of nitrite in effluent was only 0 .116 mg/L ,and no nitrite accumulation was observed ;The removal rate (47 .3% ) of the system to TN was the highest .Micro-aerobic time too long or too short would cause the nitrification and denitrification efficiency of the system dropped .
