Abstract
Fenton-oxidation process was used to treat the simulation ship sewage that had met the requirement of IMO discharge standard. The effects of reaction time, doses of H2O2 and FeSO4, pH and temperature on COD removal rate were investigated. The results showed that the optimum condition for treating simulation ship sewage was as follows: pH=3.0, concentration of H2O2=9 mmol/L, concentration of FeSO4=3 mmol/L, and reaction time=30 min. Under the optimum condition, the removal rate of COD was to 62.7%. The water quality of the effluent could meet Miscellaneous Domestic Water Quality Standard.
