Abstract
The wide pollution of Endocrine Disrupting Chemicals (EDCs) in the aquatic environment is of great concern to aquatic organisms and human health. Previous researches indicated that the main sources of the EDCs were sewage treatment plants (STPs). In this paper, we reported treatment results of synthetic wastewater containing several EDCs by a three-dimensional electrode system. Pt/Ti granular electrodes were used to enlarge the effective surface area of the anode. Concentrations of EDCs were prepared in the range of 1-1000 μg/l. In batch and continuous treatments, EDCs were successfully removed by the present system. Electric current and recycling flow rate played important roles for removal efficiency and reactor design. Energy consumptions were in the range of 0.1-10 Wh/m3. Furthermore, a selective removal of EDCs was demonstrated. From these results, we concluded that electrochemical oxidation process using the system has a potential for the treatment of trace EDCs.
