Tower-type denitrification reaction equipment for landfill leachate

The utility model provides tower-type denitrification reaction equipment for landfill leachate. The tower-type denitrification reaction equipment comprises a UASB (Upflow Anaerobic Sludge Blanket) reactor, a nitrification tank, a material mixer and a denitrification tower, the UASB reactor is provided with a gas-liquid separation device for separating materials generated by the landfill leachate in the reactor into waste gas and waste liquid; waste liquid is input into the nitrification tank, the nitrification tank is provided with an ammonia nitrogen detector and a nitrate nitrogen and total nitrogen detector, and is linked with an aeration device of the nitrification tank through a PLC control program, so that the air inlet amount of the aeration device is intelligently controlled, the energy consumption of a fan is saved, and the labor waste is reduced; waste liquid discharged from the nitrification tank and waste gas discharged from the UASB reactor are mixed in a material mixer and then discharged into a
