Sewage treatment system using permeable membrane technology

Abstract

The invention discloses a sewage treatment system using a permeable membrane technology. The system comprises a grid tank, a sewage adjusting tank, a Fenton reaction tank, an aeration biological filter tank device, a membrane bioreactor and a reverse osmosis membrane tank sequentially connected through a pipeline, wherein the sewage adjusting tank comprises a water collection tank; a water-in pipe, a coagulant pipe and a sewage pumping pipe are arranged on the water collection tank; a coagulative precipitation tank is arranged in the water collection tank, and permeable walls are placed on three sides; a mesh wall is arranged in the coagulative precipitation tank; the aeration biological filter tank device comprises a filter tank body and a back flushing tank; a gas-out pipe is arranged at the top end of the back flushing tank, and the side is connected with a gas-in pipe; a water level inductor is arranged on the inner wall of the back flushing tank; an upper-layer filter body and a lower-layer filter body are arranged in the filter tank body; a gas-out disc is arranged between the filter bodies; a filter layer impeller is arranged in the filter body; the lower end of the filter body is connected with a backwashing impeller; and a hair brush is arranged on the backwashing impeller. The system disclosed by the invention is mainly used for performing thorough harmless purifying treatment on the urban domestic waste and sewage and has the advantages of good purifying effect, high efficiency, stable and reliable operation, long service life and convenience in maintenance.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a sewage treatment system with permeable membrane technology. Background technique [0002] With the development of society, the increase of population, the increase of commercial waste, and the increasing amount of urban domestic sewage, the composition of urban sewage is becoming more and more complex and diverse. It not only contains a large amount of organic substances, but also contains high concentrations of ammonia nitrogen and toxic Harmful pollutants, if directly discharged into the environment, will cause serious pollution to the surface water environment and groundwater environment, and at the same time threaten the safety of drinking water for residents. The traditional biofilm sewage treatment system and its sewage treatment equipment are unable to fully meet the high requirements of water quality treatment in today's cities due to structural limitations.
