[Electrochemical oxidation of ammonia nitrogen wastewater using Ti/RuO2-TiO2-IrO2-SnO2 electrode].

Abstract

Electrochemical oxidation ammonia is a new method of ammonia nitrogen wastewater treatment. A study was undertaken of electrochemical oxidation ammonia wastewater in cycle mobil-electrobath. The anode was Ti/RuO2-TiO2-IrO2-SnO2 expanded metal sheet electrode. The cathode was expanded metal sheet electrode. The parameters investigated were the optimal available time for the measurement of ammonia nitrogen, flowrate and current density. The energy consumption, anode efficiency and current efficiency were analysed in different current densities. Experimental results show that when the concentration of the chlorine ion was 400 mg/L and the initial ammoniac nitrogen concentration was 40 mg/L, the flowrate had little impact on ammonia nitrogen removal, but current density had greater impact. Under the condition with flowrate 600 mL/min, current density 20 mA/cm2, electrolytic time 90 min, ammonia nitrogen removal ratio was 99.37%. The energy consumption was 500 kW x h and the anode efficiency was 2.68 h x m2 x A per kg NH4+ -N removed, and instantaneous current efficiency (ICE) was 0.28. Research has shown that electrochemical oxidation ammonia wastewater has better prospects.
