Coupled biological and photo-Fenton pretreatment system for the removal of di-(2-ethylhexyl) phthalate (DEHP) from water
چکیده انگلیسی
The photo-Fenton coupled with a biological system for the removal of di-(2-ethylhexyl) phthalate (DEHP) in wastewater was analyzed. The toxicity of DEHP-containing wastewater was found to be reduced after pretreatment by the photo-Fenton reaction. The effect of different factors, such as DEHP, Fe3+ and H2O2 concentrations and the reaction time, on degradation efficiency was investigated. The optimal time to stop the pretreatment process and introduce the effluent to the biological system was 60 min. The results show that effluent of DEHP-containing wastewater pretreated by the photo-Fenton method is biodegradable and that mineralization can be completed when the wastewater is subsequently treated in a biological system. The coupled Fenton and biological treatment system for the degradation of DEHP-containing wastewater can be successfully performed in a semi-continuous mode. These results indicate that the coupled photo-biological system is an effective and potential method for the treatment of DEHP-containing wastewater.
