The utility model provides a sewage treatment system with a methanol metering device, relates to the technical field of polyether monomer production sewage treatment, and solves the technical problemsof tedious methanol addition and inaccurate metering in polyether monomer sewage treatment. A sewage treatment system with a methanol metering device comprises a sewage station acidification pool (5), a sewage station adjusting pool (6), a sewage station secondary sedimentation pool (7), a sewage station clean water pool (8) and a sewage station aerobic pool (4) with the methanol metering device.According to the sewage treatment system with the methanol metering device, a set of device for quantitatively adding methanol according to the ratio of COD (Chemical Oxygen Demand) to nitrogen to phosphorus in the sewage aerobic tank is additionally arranged on the sewage station, so that the labor intensity of personnel is reduced, and the stability of adding methanol is improved. 本实用新型提供了一种含有甲醇计量装置的污水处理系统，涉及聚醚单体生产污水处理技
