| Abstract: | 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 NO3-- 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. |
