[0002] A sewage treatment reactor is a device or system used to treat sewage. It removes or transforms pollutants in sewage by physical, chemical or biological means, thereby purifying the water quality so that it meets the standards for discharge or reuse. The main function of a sewage treatment reactor is to remove or transform organic and inorganic pollutants in sewage, including suspended solids, organic matter, nitrogen, phosphorus, etc., to improve water quality. The use of sewage treatment reactors can improve the surrounding environment, reduce the risk of odor and disease transmission, and improve the quality of life of residents.
