The invention discloses an in-situ activation modification treatment method for a suspended filter material, which comprises the following steps of: putting 35 to 75 parts of suspended filter material into 25 to 65 parts of activating solution, stirring for 20 to 30 hours at a speed of 60 to 100 rpm, and soaking for 1 to 3 days; and taking the suspended filter material out of the activating solution, and airing. Compared with the conventional system, a wastewater denitrification treatment system with the modified suspended filter material has the advantages that: (1) the wastewater denitrification treatment system performs aeration in the same tank to remove C and N simultaneously, so the operational control process is simple; (2) COD is not needed to be removed before nitrification; (3) an additional carbon source is not needed to be added for denitrification; (4) acid and alkali respectively generated by the nitrification and denitrification can be partially neutralized mutually, and the addition of reagent
