Physiochemical method was used to treat municipal domestic sewage to achieve the goal of recycling. This work developed one combined coagulant which applied to municipal sewage and optimized the key step Fenton oxidation through extensive experiments. Results showed that the optimum reaction conditions of Fenton oxidation were pH4, reaction time 80min, addition amount of H2O2 0.1% （Volume Fraction ）, catalyst FeSO4 and Fea （SO4）3, addition amount of catalyst 0.2mg/L.The water quality reached the water quality standard for urban wastewater recycling urban miscellaneous water quality （ B/T18920-2002 ） after follow-up process.
