Abstract

Abstract

A membrane-cathode electro-Fenton process based on cathodic steel mesh membrane module was established and pilot-scale for the pretreatment of semiconductor wastewater reuse was conducted. The organic matters’ removal efficiency was investigated, and the operation parameters (including aeration, applied voltage and Fe²⁺ dosage) were also optimized. The continuous-flow pilot-scale experiment was carried out under optimal conditions and then compared with Fenton process. The results showed that the membrane-cathode electro-Fenton process could continuously produce ·OH exhibiting high potential in eliminating refractory organic compounds. Under HRT=120 min, the optimal operation parameters were found to be 0.6 m³/h of air flux, 3 V of applied voltage and 0.3 mmol/L of Fe²⁺ dosage, with removal rates of COD, TOC and H₂O₂ at (73.6±18.3)%, (51.2±12.7)% and (83.7±13.0)%, respectively. The corresponding treatment cost per unit COD was RMB 1.93/g COD. In conclusion, the membrane-cathode electro-Fenton process showed higher organic removal rate and lower cost, cimparing to the Fenton process.
