Application of Membrane Fenton Process in the Upgrading and Expansion Project of an Integrated Chemical Wastewater Treatment Plant
An integrated chemical wastewater treatment plant in Shandong Province with the capacity of 10,000 m3/d was originally designed to meet the Class 1A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002)while the chemical wastewater being treated by"Fenton+hydrolysis acidification+MP-MBR"processes.It is required to upgrade to comply with more stringent Environmental Quality Standards for Surface Water(GB3838-2002)Grade quasi-Ⅳ water quality standards and expand capacity to 2×104 m3/d.In view of the characteristics of chemical wastewater such as complex composition,high strength pollutants,toxic and harmful ingredients,refractory non-biodegradable substances,much high color and high excessive alkalinity,the combined processes of"pre-Fenton+hydrolytic acidification+two-stage A/O+membrane Fenton+activated carbon"is adopted.The operation results shows that the membrane Fenton process played a pivot role to achieve reliable and stable performance.The final effluent COD,NH4+-N,TN,TP could reduce to 19.05,0.45,5.24,0.13 mg/L respectively.Which could consistently meet the Environmental Quality Standards for Surface Water Standard quasi-Class IV.The operating cost is about 8.64 yuan/m3.
