This treatment process is a biological treatment method with air flotation as the pretreatment process, with anaerobic and aerobic as the main body. Its main structure is an air floatation tank and an anaerobic and aerobic combination device. The method is to make sewage under anaerobic and aerobic conditions. Fully mixed and contacted with the active biological carriers to achieve the purpose of degrading organic pollutants in water.
