Electrochemical Degradation with Real Textile Effluent with UV Using Platinum-plated Titanium Anode

In order to investigate the performances of electrochemical degradation with ultraviolet (UV) at 254 nm for real textile effluent, a cylinder electrolyzer with a titanium cylinder cathode was adopted to optimize initial pH, flow rate, initial Na2SO4 concentration, degradation time and cell voltage with a commercial UV lamp at 254 nm located in the center of the platinum-plated titanium cylinder anode. The experimental results illustrated that the COD of textile effluent could reduce from 120.4 mg L−1 to 80.3 mg L−1 with corresponding current efficiency of 91.60%, electrical consumption of 34.1kWh kg−1 and carbon emission of 19.4 kg CO2 kg−1 COD by electrochemical degradation with UV at 254 nm at degradation of 10 min. Additionally, degradation performances of real textile effluent by electrochemical degradation with UV at 254 nm was more effective than those of electrochemical degradation alone and UV at 254 nm alone. Therefore, electrochemical degradation with UV at 254 nm was promising for the degradation of real textile effluent in the industrial application.
