펜톤산화에 따른 복합폐수의 처리효율연구

In order to treat the wastewater containing organic compound, pre-treatment system connected with MSP(molecular separation process) was investigated. With the aim of selecting an optimum process of Fenton s oxidation, removal efficiency of each process in the optimum reaction condition was recommended. The Fe/H2O2(ferric sulfate to hydrogen peroxide)reagent is referred to as the Fenton s regent, which produces hydroxyl radicals by the interaction of Fe with H2O2. The powerful oxidizing ability and extreme kinetic reactively of the hydroxyl radical was well established. Increasing dosage of Fe/H2O2 increased removal efficiency as molar ratio of Fe/H2O2 between 0.2 and 2.5. Optimum dosage of molar ratio was 1. The removal efficiency for reaction condition was increased as pH decreased when the molar ratio of Fe/H2O2 was 1.7. Fenton s oxidation was most efficient in the reaction time 35 min for complex wastewater. Also, coagulation aid experiments using kaolin resulted in 3% of kaolin dosage.
