This study compared Fenton and photo-Fenton processes for coke wastewater treatment. Ultraviolet-assisted Fenton reaction proved more effective at removing impurities, offering an efficient solution for industrial wastewater.
Area of Science:
- Environmental Science
- Chemical Engineering
- Water Treatment Technologies
Background:
- Coke production generates complex wastewater streams requiring effective treatment.
- Advanced oxidation processes (AOPs) show promise for degrading refractory organic pollutants in industrial wastewater.
Purpose of the Study:
- To evaluate and compare the efficiency of Fenton and photo-Fenton reactions for coke wastewater treatment.
- To identify the optimal AOP for removing contaminants from coke plant effluent.
Main Methods:
- Investigated the Fenton process (iron catalyst and hydrogen peroxide).
- Examined the photo-Fenton process, utilizing ultraviolet (UV) radiation in conjunction with Fenton reagents.
- Assessed impurity removal rates and treatment efficiency for both processes.
Main Results:
- The Fenton process, particularly when enhanced with UV radiation (photo-Fenton), demonstrated superior performance.
- Significant reduction in key impurities was observed using the UV-assisted Fenton method.
- The photo-Fenton reaction achieved higher degradation rates compared to the conventional Fenton process.
Conclusions:
- UV-assisted Fenton reaction is a highly efficient method for coke wastewater treatment.
- This advanced oxidation technique offers a viable solution for mitigating environmental pollution from coke production.
- Further optimization of photo-Fenton parameters could enhance treatment efficacy.
