The utility model realizes the nitrification liquid reflux, sludge reflux and jet aeration of the biochemical part by one pump, saves energy consumption, and the pipeline is not easy to block under low flow; the sewage enters a subsequent ozone contact tank after biochemical treatment through an A/O system, ozone post-treatment is carried out in an aeration tank, and a large amount of gas can be generated due to the ozone treatment, so that a degassing tank is arranged behind the contact tank to remove redundant gas. And part of the degassed wastewater enters a filter through a pump, and suspended matters are removed and then the wastewater is discharged after reaching the standard. And in order to make the wastewater stably reach the standard, the wastewater enters the ozone aeration tank again for retreatment. This scheme sewage treatment is effectual, and the integrated design can directly reach A level's emission standard.
