The invention belongs to the technical field of treating industrialammonium chloride wastewater, and provides a device and a process for treating the ammonium chloride wastewater by a supergravity carbonization reaction, aiming at solving the problems that the current common electro-osmotic method for treating the ammonium chloride wastewater cannot realize an electrodialysis technology which is not only economical but also effective, the high-concentration ammonium chloride wastewater is hardly treated in an effective way by a membrane separation technology, and the cost is overhigh, etc. Ammonium chloride, organic amine and carbon dioxide react in a supergravity rotary packed bed to generate a mixed hydrochloric acid solution of ammonium bicarbonate and organic amine; after the ammonium bicarbonate and the organic amine are separated in a separating funnel, an organic amine solution reacts with ammonium hydroxide to regenerate organic amine; an obtained ammonium chloride solution through the regeneration is subjected to concentration, crystallization, filtration, and drying to obtain industrial grade ammonium chloride. The carbonization effect is improved; the carbonization reaction time is shortened; the treatment effect is improved; energies are saved; environment protection is realized; by adopting the method provided by the invention, reaction equipment can be minimized, the carbonization time can be shortened, the treatment effect can be improved, and the operation cost can be reduced.
