Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a full-membrane treatment device for industrial wastewater. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, it is necessary to develop comprehensive utilization and turn harm into benefit. According to the composition and concentration of pollutants in the wastewater, corresponding purification measures should be taken for disposal before it can be discharged. In the pollutant precipitation stage of wastewater treatment, flocculants need to be added to mix with wastewater. The pollutants can only be precipitated through the reaction between flocculants and wastewater. However, the existing wastewater treatment equipment cannot make the flocculant contact with the wastewater surface more fully when adding flocculants, so more persistent stirring is required to make the flocculant and wastewater mix fully, but this will result in too low filtration efficiency.

[0003] The patent with patent number CN202120646011.2 discloses an industrial wastewater treatment equipment. The liquid medicine adding device of the patent, when liquid medicine needs to be added, the liquid medicine that reacts with sewage is added through the liquid inlet bucket, and the liquid medicine enters the box body through the L-shaped liquid inlet pipe, and the second rotating motor is turned on, and the second rotating motor drives the second rotating rod to rotate, so that the second rotating rod drives the stirring blade to rotate, so that the stirring blade stirs the liquid medicine and sewage, so that the liquid medicine and sewage are convenient to contact and react better, and by turning on the electrolyzer, the electrolyzer electrolyzes the metal in the metal salt in the sewage to achieve the effect of sewage treatment. Although the patent solves the above-mentioned problems, there are still problems such as uneven contact and low efficiency between the liquid medicine and the wastewater, and the stirring blade cannot quickly form a vortex, and the mixing speed of the liquid medicine and the wastewater is not fast enough. Therefore, it is very necessary to design an industrial wastewater full-membrane treatment equipment that can quickly form a vortex in the wastewater in the sedimentation tank and increase the mixing speed of the flocculant and the wastewater. Summary of the invention

[0004] The object of the present invention is to provide an industrial wastewater full membrane treatment device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an industrial wastewater full membrane treatment equipment, comprising a sedimentation tank, the left side surface of the sedimentation tank is fixedly connected to a support platform, the upper surface of the support platform is fixedly connected to a water pump, the rear end flange of the water pump is connected to a membrane filter, the inner wall of the sedimentation tank is hinged with a material spreading box, the left side surface of the material spreading box is fixedly connected to a feed pipe, the bottom surface of the bulk material box is fixedly connected to a discharge pipe, the top of the sedimentation tank is rotatably connected to an eccentric shaft, and the inner side surface of the eccentric shaft is fixedly connected to a transmission The bottom end of the transmission rod is fixedly connected with a twisting block, a transmission groove is provided on the inner side of the material spreading box, a stirring rod is fixedly connected to the bottom surface of the twisting block, a dredging device for dredging sediment is provided at the bottom of the sedimentation tank, a biological adsorption device for adsorbing organic matter is provided inside the sedimentation tank, a sewage pipe is fixedly connected to the bottom end of the sedimentation tank, the membrane filter is fixedly connected to the inner surface of the support platform, the water pump is fixedly connected to the sedimentation tank through the water delivery tank, the feed pipe is hinged to the inner wall of the sedimentation tank, the twisting block is hinged to the inner surface of the transmission groove The top surface of the sedimentation tank is hinged, and a water inlet pipe is fixedly connected to the top of the eccentric shaft. A motor is installed on the top of the eccentric shaft, and the motor is fixedly connected to the top surface of the sedimentation tank. A solenoid valve is arranged inside the discharge pipe. Industrial wastewater is poured into the sedimentation tank from the water inlet pipe, and then flocculant is sent into the spreading box from the feed pipe. When the flocculant inside the spreading box reaches the required amount, the solenoid valve opens after receiving an electrical signal, so that the flocculant can fall from the discharge pipe and be sprinkled into the wastewater. After the flocculant reacts with the sewage, the pollutants are quickly precipitated, and the water and the pollutants are quickly separated. Then the water pump is started to precipitate the precipitate. The water on the top of the tank is pumped out and sent into the membrane filter. The membrane filter deeply filters the wastewater after the preliminary filtration through the microfiltration membrane, ultrafiltration membrane, reverse osmosis membrane, etc. arranged inside. The motor is started, and the motor drives the eccentric shaft to rotate. The eccentric shaft drives the transmission rod to swing in a conical shape. The transmission rod drives the torsion block to twist. The torsion block drives the spreading box to swing back and forth. When the spreading box swings, the spreading area can be increased, thereby increasing the contact area between the flocculant and the wastewater. When the torsion block twists, it drives the stirring rod to swing in a conical shape to stir the wastewater, so that the wastewater in the sedimentation tank quickly forms a vortex.

[0006] According to the above technical scheme, the dredging device includes a slide rail, a slider, and a scraper rod.

When the push plate moves to the bottom of the first screw rod, the arc pressure plate can extend into the sewage pipe to directly push out the accumulated and blocked pollutants.

[0007] According to the above technical scheme, the biological adsorption device includes a rotating barrel, a biological adsorption box, and a telescopic shell. The rotating barrel is fixedly connected to the top of the transmission rod, the biological adsorption box is slidably connected to the outer surface of the rotating barrel, and the telescopic shell is fixedly connected to the outer surface of the biological adsorption box. The biological adsorption device also includes a second screw, a movable shaft, a block, and a telescopic inclined plate. The second screw is fixedly connected to the upper and lower ends of the inner wall of the rotating barrel, the movable shaft is movably connected to the outer surface of the second screw, the block is fixedly connected to both sides of the outer surface of the movable shaft, the telescopic inclined plate is slidably connected to the inner surface of the telescopic shell, and slide grooves are provided on both sides of the rotating barrel, and the block and the inner surface of the slide groove are slidably connected. The biological adsorption box is fixedly connected to the side of the block away from the movable shaft, and a spring is arranged between the telescopic inclined plate and the inner surface of the telescopic shell close to the biological adsorption box. Some industrial wastewater may contain There are many organic pollutants, and most of them have a density less than that of water, which will float to the surface of the wastewater and cannot be precipitated. Before deep filtration, it is necessary to separate the excessively large organic pollutants from the wastewater. The first screw rotates while driving the rotating barrel to rotate. The rotating barrel drives the biological adsorption box to rotate through the card block. The biological adsorption box is filled with anaerobic microorganisms, which can adsorb the organic pollutants floating upward. The rotation of the biological adsorption box drives the telescopic shell to paddle inside the wastewater, destroying the cohesion of the wastewater near the biological adsorption box. When the telescopic shell rotates and paddles, the telescopic inclined plate is thrown out due to centrifugal force. The inertia generated by the throwing reduces the resistance of the wastewater to the telescopic inclined plate when it paddles. When the rotating barrel rotates, it drives the second screw inside to rotate, and the second screw drives the moving shaft to move back and forth up and down. The moving shaft drives the card block and the biological adsorption box to move back and forth up and down while rotating.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0009] The present invention is provided with a transmission rod, a twisting block, a transmission groove, and a stirring rod. When the material spreading box swings, the material spreading area is increased, thereby increasing the contact area between the flocculant and the wastewater, and improving the mixing speed of the flocculant and the wastewater. When the twisting block twists, the stirring rod is driven to swing in a cone to stir the wastewater, so that the wastewater in the sedimentation tank quickly forms a vortex, further accelerating the mixing speed of the flocculant and the wastewater, and also accelerating the sedimentation speed of the flocculants, thereby improving the wastewater treatment efficiency.

[0010] The present invention is provided with a connecting rod, a supporting rod, a push plate, and an arc-shaped pressing plate. The slider drives the scraping rod to rotate in a circle so as to scrape off the pollutants adhered to the inner wall of the bottom of the sedimentation tank, thereby preventing the continuous accumulation of pollutants and causing the sedimentation tank to discharge sewage unsmoothly and affect the filtration efficiency. The push plate reciprocates up and down to loosen the pollutants near the sewage pipe, thereby preventing too much accumulation and agglomeration of pollutants and causing clogging of the sewage pipe, thereby making the sewage discharge smoother. When the push plate moves to the bottom of the first screw rod, the arc-shaped pressing plate can extend into the sewage pipe to directly push out the accumulated and blocked pollutants, thereby further improving the dredging effect and sewage discharge efficiency.

[0011] The present invention is provided with a rotating barrel, a movable shaft, a block and a telescopic inclined plate. Anaerobic microorganisms filled in the biological adsorption box adsorb organic pollutants floating upward. The telescopic shell paddles inside the wastewater to destroy the cohesion of the wastewater near the biological adsorption box, making it easier to adsorb the organic pollutants. When the telescopic shell paddles, the telescopic inclined plate is thrown out due to centrifugal force. The inertia generated by the swinging reduces the resistance of the wastewater to the telescopic inclined plate when the telescopic inclined plate paddles, speeds up the destruction of the cohesion of the wastewater by the telescopic shell and the telescopic inclined plate, and thus improves the adsorption efficiency of the biological adsorption box. The biological adsorption box reciprocates up and down while rotating, thereby increasing the contact area with the wastewater, thereby making it easier to capture organic pollutants floating in the wastewater and promoting the adsorption effect.

The dredging device 7 also includes a connecting rod 74 and a first screw rod. 75, support rod 76, push plate 77, arc-shaped pressure plate 78, connecting rod 74 is fixedly connected to the side of scraper rod 73 away from the inner wall of sedimentation tank 1, first screw rod 75 is fixedly connected to the side of connecting rod 74 away from scraper rod 73, support rod 76 is fixedly connected to the inner wall of the bottom of sedimentation tank 1, push plate 77 is movably connected to the outer surface of first screw rod 75, arc-shaped pressure plate 78 is fixedly connected to the bottom surface of push plate 77, slider 72 and stirring rod 67 are hinged at the bottom end, scraper rod 73 and the inner wall of sedimentation tank 1 are slidably connected, first screw rod 75 and support rod 76 upper surface are rotatably connected, when push plate 77 moves to the bottom of first screw rod 75, arc-shaped pressure plate 78 can extend into sewage pipe 8 to directly push out accumulated and blocked pollutants, further improving the dredging effect and sewage discharge efficiency.

[0026] Working principle: when the agitator rod 67 swings in a cone, it drives the slider 72 to slide along the circumference of the slide rail 71, and the slider 72 drives the scraper rod 73 to rotate in a circle to scrape off the pollutants adhered to the inner wall at the bottom of the sedimentation tank 1, so as to avoid the continuous accumulation of pollutants, which leads to the obstruction of sewage discharge in the sedimentation tank 1 and affects the filtration efficiency.

[0027] See also Figure 1-7On the basis of the above-mentioned embodiment, another embodiment of the present invention includes a biological adsorption device 9, which includes a rotating barrel 91, a biological adsorption box 92, and a telescopic shell 93. The rotating barrel 91 is fixedly connected to the top of the transmission rod 64, the biological adsorption box 92 is slidably connected to the outer surface of the rotating barrel 91, and the telescopic shell 93 is fixedly connected to the outer surface of the biological adsorption box 92. The anaerobic microorganisms filled in the biological adsorption box 92 adsorb the organic pollutants floating upward, and the telescopic shell 93 moves inside the wastewater to destroy the cohesion of the wastewater near the biological adsorption box 92, so that the organic pollutants are more easily adsorbed. The biological adsorption device 9 also includes a second screw rod 94, a movable shaft 95, a block 96, and a telescopic inclined plate 97.

The rotating barrel 91 drives the biological adsorption box 92 to rotate through the block 96. The biological adsorption box 92 is filled with anaerobic microorganisms, which can adsorb the organic pollutants floating upward. The rotation of the biological adsorption box 92 drives the telescopic shell 93 to move inside the wastewater, destroying the cohesion of the wastewater near the biological adsorption box 92, making it easier to adsorb the organic pollutants. When rotating and paddling, the telescopic inclined plate 97 is thrown out due to the centrifugal force. The inertia generated by the swinging reduces the resistance of the wastewater to the telescopic inclined plate 97 when paddling, and accelerates the destruction of the cohesion of the wastewater by the telescopic shell 93 and the telescopic inclined plate 97, thereby improving the adsorption efficiency of the biological adsorption box 92. When the rotating barrel 91 rotates, it drives the second screw rod 94 inside to rotate, and the second screw rod 94 drives the moving shaft 95 to move up and down. The moving shaft 95 drives the block 96 and the biological adsorption box 92 to move up and down while rotating, so that the contact area between the biological adsorption box 92 and the wastewater is increased, so that it is easier to capture the organic pollutants floating in the wastewater, and promotes the adsorption effect.
