| Abstract English | The removal of chemical oxygen demand (COD) from wastewater containing oxalic acid was experimentally investigated using a three-phase three-dimensional electrode reactor. The experimental results show that the removal efficiency depends on the applied cell voltage, airflow, electrolysis time and the number of repeated runs. The former four factors all had a positive effect while the last factor generally had a negative effect on the COD removal in the experimental range. However, for electrolyses under the conditions of 30.0 V cell voltage, 7.01 min(-1) airflow and 60.0 min, the negative effect was negligible. After 50 runs, the electrochemical reactor could maintain a COD removal efficiency of more than 90%. |
