Aiming to ensure the quality of final effluent, combined with the existing research reports and similar engineering experience, the process of “Coagulation Sedimentation Contact Oxidation MBR” is selected as the main body to treat the wastewater in this paper. After the wastewater treatment system operates normally for one year, the results show that the removal rates of COD, BOD 5 , SS and chroma can reach 97.8%, 97.7%, 97.4% and 96.0% respectively, and the corresponding effluent concentrations are 96 mg/L, 25 mg/L, 18 mg/L and 20 mg/L, respectively, which meets and is better than the secondary discharge standard of the Integrated Discharge Standard of Water Pollutants in Haihe River Basin of Shandong Province (DB37/675-2007). The process has certain engineering advantages as the quality of wastewater treatment is high and the total cost of electricity and medicament for the wastewater treatment is low.
