Cylinder type integrated sewage treatment device

Abstract

The invention relates to a cylinder type integrated sewage treatment device which comprises a reaction tank, a filtering membrane set, a suction pump, a plurality of bubble releasers, an air dissolving system and a stirrer, wherein the reaction tank has a cylinder structure; the reaction tank is divided into a mixing area, a settling area, a flow guiding area and a filtering reaction area from center to periphery in turn; a stirring blade is arranged in the mixing area; the stirring blade is used for floating the sludge flowing back from the bottom of the settling area and the filtering reaction area; the micro-flocculated grains, which are newly generated in the manner of mixing the colloid, oil, suspended solids and coagulant in sewage, can be quickly adsorbed to the suspending sludge and then enter into the settling area for settling; the sewage treatment device has an excellent sludge refluxing effect and low energy consumption of water flow; the bubble releasers are distributed at the bottom of the filtering reaction area; the filtering membrane set is distributed in the filtering reaction area; the suction pump is connected with a water draining end of the filtering membrane set through a pipeline and is used for pumping the treated water; and the discharged water is high in quality and the effect is excellent.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a cylindrical integrated sewage treatment equipment. Background technique [0002] At present, the pollution brought by industrialization has greatly deteriorated the human living environment. All kinds of water sources are polluted to some extent. People need to join the air flotation process section in the process sections of tap water pretreatment, municipal sewage standard discharge, etc. to pretreat suspended solids, colloids, oils and other impurities in sewage. And use the sedimentation tank for mud-water separation, the sedimentation tank requires a large area, and the sedimentation time is long. The use of membrane reactors for mud-water separation can not only greatly reduce the treatment time, but also intercept sludge more effectively and improve the quality of produced water. However, the traditional membrane reactor process is usually a split type, which ...

AI Technical Summary

Problems solved by technology

The use of membrane reactors for mud-water separation can not only greatly reduce the treatment time, but also intercept sludge more effectively and improve the quality of produced water. However, the traditional membrane reactor process is usually a split type, which is separated from other reaction tanks and wastes land.
