Abstract

The invention discloses a sewage treatment system, which integrates hydraulic vortex flow velocity adjustment and control, bubble jet / intensified aeration and a solid / liquid vortex separation technique together to remove a variety of pollutants in sewage. Sewage gets into a vortex capable of adjusting and controlling vortex flow velocity in the system disclosed by the invention and downwardly moves in the form of a vortex and along the axial direction of a vortex pipe; the air gets into the vortex pipe via a microporous tube of an air injector, so that micro-bubbles are formed to be mixed with the sewage, and thereby an aerating effect is achieved; under the action of centrifugal force and buoyancy force, the bubbles is discharged from the central tube of a flow velocity adjustment valve, and thereby volatile pollutants and peculiar smell-producing pollutants in the sewage are removed. Meanwhile, low-density suspending pollutants are gathered in the cavity of the sewage vortex, and are removed by a siphon system; high-density suspending pollutants pass through a solid / liquid vortex separator and are discharged via a solid discharge valve, and the treated water is discharged via a drain pipe. The sewage treatment system disclosed by the invention is suitable for the pretreatment of a variety of sewages or the first stage, and has the characteristics of small size, small occupied floor, high pollutant removal efficiency, high adaptability and the like.

Description

technical field

[0001] The invention relates to a sewage treatment device. Background technique

[0002] With the continuous development of the global economy, the destruction of the natural environment by humans and the waste residue, waste gas, and waste water generated in the production process are discharged or directly discharged without effective treatment, causing heavy metal pollution in the soil and groundwater pollution, acid rain and smog in the air Formation of pollution, eutrophication of rivers and lakes, and other pollution phenomena have brought unprecedented challenges to the space on which human beings depend for survival. In the 21st century, one of the two most important problems faced by human beings is the living environment problem (the other is the energy problem). Among them, water pollution has posed the most serious threat to human survival and safety, and has become a major threat to human health, economy and A major obstacle to sustainable socia...
