[0002] Invention patent "Three-phase azeotropic ammonia flooding method" application number 201310669634, 1, is a high-concentration ammonia nitrogen wastewater treatment method, which has low construction investment, low operating costs, high deamination efficiency, and a wide range of applications, but in the deamination process In the specific bathing operation, it is necessary to let the solid, liquid and gas mixed wastewater stand still, take out the supernatant and put it in the pH callback reactor, and adjust the pH value to near neutral by aeration or adding acid. The process is complicated and cumbersome, and the operation Discontinuous, difficult to achieve industrialization

Embodiment example
[0012] Pig wastewater from a large pig farm, after biogas generation, the biogas slurry contains NH 3 -N2000~4000mg / l, after three-phase azeotropic ammonia flooding reaction, the effluent NH 3 -N drops to between 10 and 50 mg / l, which is better than the national "Discharge Standard of Pollutants for Livestock and Poultry Breeding Industry" (GB15896-2001).
