The application discloses a method for relieving the inhibition of carbon dioxide on denitrification and promoting denitrification. The method comprises the following steps: inputting 0.3%-20% of CO2 into a closed reactor, inoculating Proteiniphilum aceticum into a denitrification system of P.denitrificans, and realizing the effect of relieving the inhibition of CO2 on denitrification and promoting the denitrification efficiency through the interaction of the two bacteria, wherein the inoculation ratio of P.denitrificans and Proteiniphilum is 1:2-1:15, the carbon-nitrogen ratio of the denitrification system is 1-5, the pH of the denitrification system is 6.0-9.0, and the temperature of the denitrification culture is 30-37 DEG C. The application promotes anaerobic denitrification by using the interaction of Proteiniphilum and P.denitrificans, has low cost, has no secondary pollution, can obviously relieve the inhibition of CO2, improves the nitrate removal effect, and reduces the accumulation of nitrite and nitrous oxide.
