Removal of ammonia nitrogen from wastewater by three-dimensional electrode system based on solid waste containing iron

In order to solve the problem of ammonia nitrogen pollution, three-dimensional electrode electrochemical oxidation technology is utilized transform nitrogen. The influence influent pH, power supply and electrolyte concentration on removal by method its mechanism were discussed single factor variable analysis. particle emission scanning electron microscope (SEM) energy dispersive spectroscopy (EDS). results show that efficiency higher than two-dimensional electrode. When aqueous solution neutral, direct indirect reactions can reach best state, highest. Within a certain range, electrolytic will increase with voltage concentration. reduction spacing in range enhance improve electrolysis Under conditions pH 7, 14 V, 0.1 mol/L, 1 cm, time 50 min, be completely removed from
