Abstract
A container-type sewage treatment device is transformed from a standard container. The interior of the container is divided into two biochemical reaction areas and a mud water separating area by separating plates. Biological fillers are added into the biochemical reaction areas, and porous separating plates are used to intercept the fillers so that concentrations of activated sludge and volume loading of the whole device are increased. Inclined pipe fillers or inclined plate fillers are added into the mud water separating area so that surface loading of the mud water separating area is increased. Liquid supernatant of the mud water separating area is final yielding water which can reach the standard of first class B of Pollutant Emission Standard of Town Sewage Treatment Plant. The container-type sewage treatment device has high treatment efficiency and convenient transportation, and is a treatment device which can be produced.
