Air-water dual-purpose packing plug-flow device

Abstract

The invention discloses a gas-water dual-use filling material circular plug flow device, which comprises a material conveying tube for conveying a filling material, a power plant for providing a medium, a guiding and conveying member for conveying the medium, and an injection member which is used for guiding the medium in the guiding and conveying member to move in the material conveying tube to generate a pushing force or a suction force, and the guiding and conveying member is communicated with the injection member. The gas-water dual-use filling material circular plug flow device is arranged in an aeration tank and below the water surface, a feed end of the material conveying tube is arranged near a filling material stacking position, and a discharge end of the material conveying tube is arranged at a position in alignment to a principle stacking position; a support frame is arranged in the aeration tank to fix the device, the injection member guides vortex motion of the medium, so that a powerful pushing force or suction force is formed in the material conveying tube to together suck the filling material in the stacking position and sewage in the aeration tank in, the filling material is pushed backwards out by the pushing force formed in the material conveying tube, and the problem of filler stacking can be quickly solved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an air-water dual-purpose filling circulation pushing flow device. Background technique [0002] During the operation of the biological contact oxidation treatment tank for water supply and drainage, the filler is affected by the water flow, and most of it moves to the water outlet with the flow of water, and accumulates in large quantities near the outlet, forcing the biological contact oxidation tank to gradually form a local "pile up like a mountain". "Phenomenon, the accumulated filler is easily exposed to the sun, and the problem of biofilm drying and stoppage of operation occurs, which seriously affects the water quality and water quantity of water supply and drainage purification treatment. At present, it is mainly salvaged by hand and put back into the aeration tank, which is not only time-consuming and laborious, but also prone to microbial stripping ...

"Phenomenon, the accumulated filler is easily exposed to the sun, and the problem of biofilm drying and stopping of operation occurs, which seriously affects the water quality and quantity of water supply and drainage purification treatment

At present, it is mainly salvaged manually and put back into the aeration tank, which is not only time-consuming and laborious, but also prone to microbial defilming during the salvage process, which affects the water quality of purification treatment
