摘　　要：通过采用全流程分析方法,总结了太湖流域某市政污水处理厂TN指标针对新一轮提标改造的达标难点,研究了反硝化滤池小试实验的启动与碳源投加的最佳C/N比。结果表明,低C/N比进水及内回流不足限制了脱氮效率的进一步提高;通过实际污水处理厂二级出水进行反硝化滤池的小试实验研究,发现反硝化滤池启动4天后挂膜成功,在外加碳源C/N比为2条件下,出水NO_(3)^(-)-浓度可降至3 mg/L以下,且不会导致出水COD浓度升高,所得结果比其他文献报道的碳氮比偏低,为未来高标准TN排放污水处理厂的运行管理提供基础数据。The whole process analysis method is applied to summarize the difficulty of meeting the TN index of a municipal sewage treatment plant in the Taihu Lake Basin for the new round of standardization and figure out the best C/N of the start-up of the denitrification filter pilot test and the proboble carbon source.The result shows that the low C/N of the influent and the insufficient internal reflux limit the further improvement of the denitrification efficiency;The small test of the denitrification filter was carried out through the secondary effluent from the actual sewage treatment plant.It was found that the membrane was successfully sprayed 4 days after the start of the denitrification filter.Under the condition of the C/N ratio of the carbon source being 2,the effluent NO_(3)^(-)- concentration It can be reduced to below 3 mg/L,and will not cause the effluent COD concentration to rise.The results obtained are lower than the carbon-nitrogen ratio reported in other literatures,which provides basic data for the operation management of high-standard TN wastewater treatment plants in the future.
