    曝氣機的工作原理

    Aerator, which directly injects "microbubbles" into untreated sewage through diffuser impeller. Under the joint action of coagulant and flocculant, suspended solids undergo physical flocculation and chemical flocculation, thus forming large flocs of suspended solids. Under the floating action of bubble groups, "flocs" float on the liquid surface to form scum, which is separated from water by slag scraper; There is no need to clean the nozzle, and no blockage will occur. The equipment has good integrity, convenient installation, and saves operating cost and floor space.
