Influence of Iron-loaded Activated Carbon on Anaerobic Biodegradation of Dyeing Wastewater
Dyeing wastewater is characteristic of compositional complexity,high color and poor biodegradability,which is difficult to treat.Anaerobic biological technology is one of the effective methods to treat dyeing wastewater.However,the complexity of the anaerobic biological treatment process,which involves the synergistic metabolism of multiple microorganisms,results in the slow degradation rate.Therefore,to improve the anaerobic biodegradation performance of the dyeing wastewater,the iron-loaded granular activated carbon is prepared and applied to the anaerobic biological treatment of the simulated dyeing wastewater in this study.The SEM-EDS and XRD analytical results show that the surface of the granular activated carbon has been successfully loaded with iron.The results of COD and color removal indicate that the iron-loaded granular activated carbon prepared with the Fe3+to Fe2+ratio of 2∶1 can significantly improve the anaerobic biological treatment performance of the dyeing wastewater.
