Abstract

Background and Aim: 2,4-Dichlorophenol (DCP) is a compound generated in a variety of industrial processes and also by chlorine disinfection of water polluted with phenolic compounds. Dumping of DCP into the environment and water resources is of great concern because of the compound's intense odor and toxicity. DCP is very soluble and resistant to BIODEGRADABILITY so it cannot be removed through conventional water and wastewater treatment processes. On the other hand, pollution prevention (P2) strategies have not been able to resolve the problem.Material and methods: In this study, one of the AOPs named FENTON was used for DCP degradation. The method is based on simultaneous use of hydrogen peroxide and ferrous sulfate.Results: Results of treatment with hydrogen peroxide and ferrous ion (as FENTON reagent ingredients) indicate that by oxidation of 50 mg/L DCP at 60 minutes contact time with iron concentration kept at 15 mg/L and various concentrations of H202 (50 and 100 mg/L), the efficiency of COD (Chemical Oxygen Demand) reduction would go up from 65% to 80% with higher concentrations of H202. We also determined the effect of various concentrations of ferrous ion on DCP oxidation rate. The results showed the prominent role of this ion in DCP treatment: increasing Fe concentration from 5 to 15mg/L produced a 60% reduction in COD occurred in 10 and 60 minutes contact times. Another conclusion was that the oxidation of DCP solutions by FENTON had a major effect on BIODEGRADABILITY so that BOO: COD ratios of these solutions increased significantly after this oxidation.Conclusion: Pretreatment of waste containing dichlorophenol by the FENTON reagent can enhance the BIODEGRADABILITY of this chemical and perhaps of similar compounds in a short time interval.
