[0027] The method of the present invention is: the reaction column includes Fe-C micro-electrolysis reaction column and natural zeolite reaction column, Fe-C micro-electrolysis reaction column and natural zeolite reaction column are connected together, Fe-C micro-electrolysis reaction column is on top, natural zeolite reaction column The zeolite reaction column is below, the upper part of the reaction column is connected to the water tank, and the lower end of the reaction column is connected to the outlet pipe. The water tank contains black and odorous water. The black and odorous water passes through the Fe-C micro-electrolysis reaction column through gravity. Electron transfer reduces nitrate nitrogen and nitrite nitrogen to ammonia nitrogen; ferrous ions will appear in the effluent of the Fe-C microelectrolysis reaction column; when the effluent water flows through the natural zeolite reaction column, the residual ferrous ions in the water will be combined with the water The...
