Ammonia nitrogen wastewater seriously pollutes the environment, for which finding an efficient method of treatment is imperative. Electrocatalytic oxidation technology has great potential in wastewater treatment attributed to its strong oxidizing properties, cleanliness and economy. Electrode materials and plate spacing have great impact on the energy consumption and oxidative degradation efficiency in the process of degradation of ammonia nitrogen wastewater. In this paper, the effect of electrode materials and plate spacing on the electrocatalytic oxidation was studied. It was shown that the degradation efficiencies of ammonia nitrogen was more than 90% within 120 min under the optimum reaction conditions of ruthenium-plated titanium electrode and plate spacing 65 mm. The experimental results in the present study prove that the electrocatalytic oxidation technology is an efficient method, which offering a new idea for the treatment of ammonia nitrogen wastewater.
