The invention discloses a device for removing nitrate nitrogen in a resin desorption solution and an application process of the device. The device comprises a reactor, an aeration device, a water inflow box and an ozone adding device. An ozone contact reactor is arranged on the inner layer of the reactor of a concentric cylinder structure, and an anoxic reactor and a sludge precipitator which are spaced are arranged on the outer layer of the reactor. The anoxic reactor is communicated with the bottom of the sludge precipitator, a water outlet communicated with the anoxic reactor is formed in the upper end of the ozone contact reactor, the lower end of the ozone contact reactor is filled with ozone reaction catalytic filler, the ozone contact reactor is connected with the water inflow box through a first connecting pipeline, and the ozone contact reactor is connected with the ozone adding device through a second connecting pipeline. The device further comprises an ozone collecting device, a gas inlet of the oz
