摘　　要：通过对某城市污水厂反硝化深床滤池的运行研究,分析了m(C)/m(N)值、滤池HRT及DO等对脱氮效果的影响。结果表明m(C)/m(N)值大于5时,会影响脱氮效果,导致COD去除率降低,HRT为30min时,最适合该处理工艺的脱氮,并且建议采取措施减少跌水复氧,确保脱氮效果,减少复氧消耗的外加碳源。The analysis process about effects of C/N,HRT and DO in filter on nitrogen removal were carried out in a municipal WWTP.The study shows that the removal efficiency of nitrogen and COD will be lower,when C/N>5 and the HRT=30 min is most suitable.It is suggested that reducing reoxygenation to ensure the effect of nitrogen removal,meanwhile reduce the consumption of additional carbon sources.
