Integrated technology in sequential treatment of organics and heavy metal ions wastewater
This invention offers an integrated technology in sequential treatment of wastewater. Low biodegradable organics and heavy metal ions are both contained in wastewater from surface finishing processes. The aim of the invention is to find the solution for treatment of organics and heavy metal ions in complicated wastewater that contains organics and heavy metal ions sequentially. Low biodegradable organics are oxidized by a fenton process with pH ranging from 2 to 5 and temperature ranging from 20° C. to 100° C. Heavy metal ions are then treated by a ferrite process with pH ranging from 8 to 12 and temperature ranging from 20° C. to 100° C. The integrated technology of the fenton process and the ferrite process (2FP) is advantageous to treat the wastewater from surface finishing processes, decrease the production of iron sludge caused in the fenton process and increase the quality of ferrite products.
