[0002] Since industrial waste water contains more nitrogen and phosphorus substances, in order to ensure the environmental friendliness of the discharged water, it is often necessary to remove the nitrogen and phosphorus substances in the wastewater. Generally, aerobic anaerobic wastewater treatment methods are often used for wastewater treatment. Aerobic anaerobic wastewater treatment process is a process that uses the metabolism of microorganisms to treat pollutants in wastewater. It mainly includes two methods: aerobic treatment and anaerobic treatment. Aerobic treatment uses the metabolic activity of aerobic microorganisms under the action of aeration to remove pollutants in wastewater, while anaerobic treatment uses the metabolism of anaerobic microorganisms to remove pollutants in wastewater under the condition of oxygen isolation.

The servo motor 6 drives the rotating shaft 5 to rotate, controlling the cleaning claw 19 to rotate around the central axis of the rotating shaft 5.
