A nitrifying apparatus for eliminating surface foam is shown in FIG. 1, and comprises an apparatus body 1, a reflux device 3, a spray storage tank 5 and a spray assembly 4. A reaction cavity 2 is arranged in the device main body 1, and the reaction cavity 2 is used for carrying out nitration reaction on the mud-water mixture. The liquid spray storage box 5 is fixedly arranged at the top of the device main body 1 so as to intensively store the returned clear liquid water. One end of the reflux device 3 is communicated with the device body 1, the other end of the reflux device 3 is communicated with the spray liquid storage box 5, and the reflux device 3 refluxes clear liquid water into the spray liquid storage box 5 so that the solution with foam floating on the surface is remained in the reaction cavity 2. Spray set 4 fixes on the hydrojet bin 5 and be located the inside upper end of reaction chamber 2, spray set 4 with hydrojet bin 5 intercommunication, spray set 4 aims at the solution injection of taking the foam with the clear solution water of backward flow and smashes the foam.

Specifically, as shown in fig. 1, during the reaction, the mud-water mixture is introduced into the reaction chamber 2 and the flocculant is added for reaction, and meanwhile, the clear water in the reaction chamber 2 is refluxed into the spray storage tank 5 by the reflux device 3, and the clear water in the spray storage tank 5 sprays water beads into the reaction chamber 2 through the spray assembly 4 to break up bubbles floating on the water surface, so that the clear water can be refluxed and also removed, and the soil in the bubbles enters the reaction solution to be in full contact reaction with the flocculant, which is beneficial to complete desliming.
