Electrochemical Oxidation of the Effluent from Coking Wastewater Treatment Plants Using Ti/RuO₂-IrO₂ Electrode

Abstract:

This paper explored the electrochemical oxidation of coking wastewater with Ti/RuO₂-IrO₂ anode. The effects of electrodes connections, area-volume ratio and aeration on the removal efficiency were studied and the ammonia removal mechanism was investigated. The results show that the highest NH₄⁺-N and COD removal efficiency and current efficiency are achieved at the area-volume ratio of 14.44m²/m³ and electrode distance of 0.5cm. Unipolar connection is better than bipolar connection. For electrochemical oxidation of ammonia, the chloride ion is the main factor affecting nitrogen removal. NH₄⁺-N is removed mainly by the oxidation of hypochlorous.
