Treatment of simulated ammonia nitrogen wastewater by Fe<sup>3+</sup>-TiO<sub>2</sub>/AC based three-dimensional electrode

Guide

Abstract The Fe³⁺-TiO₂/AC composite material is prepared by slurry method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). A three-dimensional electrode electrochemical system is constructed using the Fe³⁺-TiO₂/AC composite material as particle electrode and graphite plates of the same specifications as anode and cathode to treat simulated ammonia nitrogen wastewater. The effects of electrolytic voltage, electrolyte concentration(NaCl), initial pH and particle electrode dosage on the removal of ammonia nitrogen are investigated, and the response surface method is applied to optimize the conditions for the treatment of simulated ammonia nitrogen wastewater. The result show that the removal rate of ammonia nitrogen from the simulated wastewater is 96.86% after 40 min of electrolysis under the conditions of electrolytic voltage of 18 V, electrolyte concentration(NaCl) of 6.7 g·L^-1, initial pH of 9.00 and particle electrode input of 10.0 g·L^-1. After optimization by response surface method, the best ammonia nitrogen removal rate of simulated wastewater is 97.61% at 40 min with electrolysis voltage of 18 V, particle electrode input of 9.9 g·L^-1 and initial pH of 9.10. The above research conclusions can provide some reference for the industrial treatment of ammonia nitrogen wastewater.
