An industrial acid sewage treatment device

Abstract

The invention discloses an industrial acidic waste water treatment device. The industrial acidic waste water treatment device comprises a tank body, oxygen supply pipelines, and aeration parts which are arranged in the tank body; the aeration parts are detachably connected with the oxygen supply pipelines, and each aeration part comprise a pedestal, a main pipe arranged on the pedestal, and a plurality of branched pipes which are connected with the main pipe; a blocking part capable of rolling forward under oxygen supply states and a magnetic part used for driving the blocking part to roll backward under oxygen supply stopped states are arranged in each branched pipe; and each magnetic part is arranged on the internal wall of the corresponding branched pipe. According to the industrial acidic waste water treatment device, the blocking parts and the magnetic parts are arranged in the branched pipes, so that blocking of the branched pipes is realized, the internal parts of the branched pipes are maintained to be clean, blocking of the branched pipes by sludge is avoided, the corrosion resistance is excellent, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of industrial sewage treatment, and in particular relates to an industrial acid sewage treatment device. Background technique [0002] In the treatment of industrial acidic sewage, it is necessary to aerate the wastewater, but the existing aeration equipment uses a rubber diaphragm to bulge to form micropores so that the gas is discharged outwards. This method can effectively block the water body and the pollutants in the water body , to avoid micropore blockage; but because the rubber diaphragm is easily corroded and aged for a long time, its sealing effect will gradually deteriorate, and the micropore space on the diaphragm becomes larger, resulting in larger air bubbles, and sludge is easy to enter For the micropores, causing micropore blockage. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an industrial acid sewage treatment device wi...

Problems solved by technology

The present invention disperses the oxygen transported by one pipeline into multiple pipelines by setting branch pipes on the aeration part, reduces the amount of oxygen accumulation, enhances the dissolution rate of oxygen when it is discharged into the water body, and improves the oxygen concentration. Utilization rate: install plugging parts and magnetic parts on the branch pipes, and in the absence of oxygen, the magnetic parts attract the plugging parts, so that the plugging parts block the branch pipes and prevent water from leaking into the main pipe from the branch pipes; Under the condition of oxygen flow, when the pressure of oxygen reaches to overcome the magnetism of the magnetic piece, the blocking piece rolls in the branch pipe, opening the oxygen inlet of the branch pipe, so that oxygen can be discharged from the branch pipe, and when the oxygen exhaust is about to stop, the magnetic piece makes the sealing piece The blocking member is reset to re-block the branch pipe, which completely prevents the impurities in the blocked water from entering the branch pipe and blocking the oxygen discharge port; and during the rolling process of the blocking member, it will bring up solid pollutants accumulated in the branch pipe , and the pollutants are completely washed out of the branch pipe through oxygen, which can always keep the branch pipe clean and completely eliminate the situation that the branch pipe is blocked by silt, and the plugging part is made of metal, which is corrosion-resistant and has a strong resistance to acidic water. service life
