Fenton's Oxidation

Abstract Dye wastewater is one of typically non-biodegradable industrial effluents. A new process linking Fenton’s oxidation with biological oxidation proposed in this study was investigated to degrade the organic substances from real dye wastewater. During the combination process, the Fenton’s oxidation process can reduce the organic load and enhance biodegradability of dye wastewater, which is followed by biological aerated filter (BAF) system to further remove organic substances in terms of discharge requirement. The results showed that 97.6% of chemical oxygen demand (COD) removal by the combination process was achieved at the optimum process parameters: pH of 3.5, H2O2 of 2.0 mL/L, Fe(II) of 500 mg/L, 2.0 h treatment time in the Fenton’s oxidation process and hydraulic retention time (HRT) of 5 h in the BAF system. Under these conditions, COD concentration of effluent was 72.6 mg/L whereas 3020 mg/L in the influent, thus meeting the requirement of treated dye wastewater discharge performed by Chinese government (less than 100 mg/L). These results obtained here suggest that the new process combining Fenton’s oxidation with biological oxidation may provide an economical and effective alternative for treatment of non-biodegradable industrial wastewater.

This study was designed to evaluate (1) the removal of the non-biodegradable organics and color by Fenton's oxidation (2) the feasibility of Fenton's oxidation as a pretreatment or tertiary treatment following the activated sludge process in the pigment wastewater. The study was divided into two parts. The first part consisted of investigations on raw Yellow wastewater and Red wastewater, the second part was carried out on the final effluent from the existing extended aeration treatment plant. The batch test was conducted to determine the optimum conditions for plant operation such as pH, H2O2 dosage, molar ratio of Fe2+/H2O2 and contact time. It was found that the removal efficiencies of COD were 54.2%, 52.6% and 58.9%, the removal efficiencies of the color were 91.2%, 18.1% and 45.7%, for Red, Yellow Wastewater and Final Effluent, respectively. In the Yellow wastewater, BOD5COD ratio was not changed much after Fenton's oxidation, but in the case of the Red wastewater, BOD5COD ratio was increased from 0.04 to 0.36. Therefore Fenton's oxidation process is a very effective means for a pretreatment or tertiary treatment in the Pigment wastewater.
