摘要: Abstract Laboratorial scale experiments were conducted to investigate a novel system three-dimensional catalytic electro-Fenton (3DCEF, catalyst of sewage sludge based activated carbon which loaded Fe 3 O 4 ) integrating with membrane bioreactor (3DCEF–MBR) on advanced treatment biologically pretreated coal gasification wastewater. The results indicated that 3DCEF–MBR represented high efficiencies in eliminating COD and total organic carbon, giving the maximum removal 80% 75%, respectively. integrated significantly reduced transmembrane pressure, 35% lower than conventional MBR after 30 days operation. enhanced hydroxyl radical oxidation bacteria self repair function mechanisms for performance. Therefore, was expected be promising technology engineering applications.
