Abstract

A tetragonal device is made from carbon steel materials. A water pump and a jet aerator inject the domestic sewage and air into the bottom of the device, and rubber particles fillers are impacted and fluidized. With contact with the microbe growing attachedly on the rubber particle fillers, the organic matters and toxic and harmful substances in the sewage transform into carbon dioxide and water and other innoxious substances. With collision and flocculation, the sludge is hindered when rising and forms into a big sludge particle and settles into a sludge collector, which was drained out by the gravity of a discharge pipe. With the separation of sludge with water, the sewage is transformed into treated water. After sterilized by an ultraviolet lamp, the treated water achieves standard-met discharge. Being fluidized, the rubber particle fillers are separated in the device by a stainless steel screen and have continual chemical interaction with the sewage. After a while, the contact sediment filter materials have to be backwashed.
