Experimental study on the treatment of furfural wastewater by ozone-Fenton coupling intensification
Furfural production generates wastewater characterized by high concentration, strong acidity, and poor biodegradability, necessitating treatment before discharge. The Fenton process, known for its cost-effectiveness, is widely used for industrial wastewater treatment. However, it has limitations such as a narrow pH operating range and significant secondary pollution. To optimize this, researchers have explored combining Fenton with other processes, yet few have studied its synergy with O3. This study investigates the advantages of O3/Fenton coupling in treating furfural wastewater, comparing the capabilities of O3, O3/H2O2, Fenton, and O3/Fenton processes. Results show that ozone-Fenton coupling exhibits superior industrial treatment performance. Post-treatment, the wastewater's B/C ratio reached 0.43, TOC removal rate was 33.6%, and ozone utilization efficiency was 74.6%, surpassing other methods. UV absorption spectra analysis indicated enhanced degradation of aromatic compounds, transforming them into smaller organic molecules. This study highlights ozone-Fenton coupling as a low-cost, effective enhancement for furfural wastewater treatment, offering significant guidance for future research in this field.
