초록

Phenol, often discharged from petroleum and fine chemical industries is potential carcinogen and was classified into priority pollutant by EPA in USA. It causes serious environmental and health problem if discharged to the environment such as soil or aquifer. The removal efficiency of phenol and COD using Fenton treatment(Hydrogen Peroxide and Ferrous Sulfate) was observed and biodegradability (BOD$_{5}$/COD$_{cr}$) of reaction products were also examined. When 50 mg/l of phenol was treated by Fenton's Reagent(50 mg/l of hydrogen peroxide and 900 mg/l of ferrous sulfate), the removal efficiency of phenol and COD was 100% and 80% respectively in 10 minutes, which suggested this method can be used as actual phenol removal process. The initial biodegradability of 500 mg/l phenol solution was 0.7 but decreased as hydrogen peroxide was increased.
