Description

Technical Field

[0001] The invention relates to a wastewater treatment system, in particular to an anodic oxidation production wastewater treatment system. Background Art

[0002] The process of forming an oxide film on aluminum products (anodes) by aluminum and its alloys in the corresponding electrolyte and specific process conditions due to the action of an applied current is called anodic oxidation. Anodizing will produce wastewater containing high concentrations of aluminum ions, fluoride ions, phosphate ions, surfactants and a variety of organic dyes.

[0003] Anodic oxidation wastewater contains high concentrations of ionic pollutants, which are difficult to treat and have large pH fluctuations. These substances not only affect the COD and BOD of the wastewater, but may also cause pH fluctuations in the water body, putting pressure on the ecological balance of the environment. The existing technology uses a coagulation and sedimentation integrated treatment process to treat wastewater, but there are the following problems:

[0004] 1) The equipment is suitable for low suspended solids content in influent, generally SS <5000mg / L, and is allowed to reach 5000-10000mg / L in a short time;

[0005] 2) Mechanical stirring and scraping are required, which consumes a lot of energy and is troublesome to maintain;

[0006] 3) The sludge discharge volume is large, and the water content of the sewage is as high as 98%;

[0007] 4) It occupies a large area and requires high initial investment.

[0008] In view of this, technicians in this field have proposed an anodizing production wastewater treatment system, designed a system for treating wastewater with a large suspended matter content, and can quickly mix flocculants with the flow of sewage, to achieve a treatment system that allows sewage to be introduced while discharging the treated supernatant, so as to achieve rapid dynamic treatment of sewage in a limited space. Summary of the invention

[0009] In view of the deficiencies in the prior art, the present invention provides an anodizing production wastewater treatment system, which is designed with a sedimentation tank with a pressurizing component. A multi-stage grid plate is used to block the water flow to shorten the sedimentation interval, and the closed sedimentation tank is pressurized to accelerate the flocculent sedimentation. A scraper scrapes off the sediment at the bottom of the sedimentation tank, and a roller cooperates with a rolling plate to roll the settled sludge to reduce the water content of the discharged sewage, thereby improving the existing anodizing production wastewater treatment system. The system has the following problems: it occupies a large area, is not suitable for sewage treatment with a lot of suspended matter, and has a high water content in the discharged sewage.

[0010] To achieve the above objectives, the present invention is implemented through the following technical scheme: an anodizing production wastewater treatment system, including a sedimentation tank, sewage is passed into the sedimentation tank, a regulator is added to adjust the pH, and a coagulant is added to treat harmful ions in the sewage to generate flocs, and after precipitation, the supernatant is discharged and the sediment is recovered or treated in the form of solid waste.

[0011] A booster assembly is provided above the sedimentation tank, and the booster assembly includes a sealing cover plate, and the sealing cover plate is hingedly provided above the sedimentation tank. The sealing cover plate seals the sedimentation tank and provides movable support for workers above the sedimentation tank, thereby forming a closed sedimentation environment, making it convenient to pressurize the sedimentation tank to help the rapid sedimentation of flocs.

[0012] A sleeve is provided through the side of the sealing cover plate, a piston is slidably provided inside the sleeve, and the sleeve cooperates with the piston to pressurize the environment by filling air into the sedimentation tank, thereby helping to accelerate the coagulation and precipitation of flocs.

[0013] The inner bottom of the sedimentation tank is provided with rollers, and the sedimented sludge is rolled by the rollers to reduce the water content of the discharged sewage.

[0014] Preferably, a drug addition hopper is provided above the liquid inlet end of the sedimentation tank, and a regulator and a coagulant are added to the sewage input into the sedimentation tank through the drug addition hopper to stabilize the pH value of the sewage and react with harmful ions in the sewage to form flocs.

[0015] A grid plate is arranged inside the sedimentation tank. By arranging a multi-level grid plate in the sedimentation tank, the flow speed of sewage is slowed down, thereby shortening the sewage sedimentation distance and reducing the treatment cost investment.

[0016] An aeration pipe is provided at the inner bottom of the sedimentation tank to accelerate the sedimentation of flocs by aeration. A sewage pipe is connected through the inner bottom of the sedimentation tank to discharge the sludge settled at the bottom of the sedimentation tank through the sewage pipe without manual shoveling. The head and tail ends of the sedimentation tank and the sewage pipe are connected to power pumps, which provide power for the inflow and outflow of water and the discharge of sewage from the sedimentation tank.

[0017] Preferably, the inner wall of the sedimentation tank is fixedly connected with a mounting rail, and the mesh plate is arranged on the inner side of the sedimentation tank by plugging the mounting rail. The multiple layers of mesh plates are equidistant and parallel. The mesh plates installed in multiple stages by the mounting rail divide the space in the sedimentation tank into a uniform block structure, which has a retarding effect on the sewage flowing between the inlet and outlet ends of the sedimentation tank, facilitates the sedimentation of flocs during the flow of sewage, and also facilitates the cleaning of the mesh plate.

[0018] The side surface of the mesh plate corresponds to the installation rail fixedly connected with a limit stopper, and the limit stopper cooperates with the installation rail to position the installation of the mesh plate, leaving a space at the bottom of the sedimentation tank for convenient cleaning of sludge.

[0019] Preferably, the inner wall of the sedimentation tank is symmetrically fixedly connected with a guide bar, and the guide bar is arranged parallel to the inner bottom wall of the sedimentation tank. The inner side of the sedimentation tank is slidably provided with an installation frame through the guide bar. Under the guidance of the guide bar, the installation frame moves along the direction parallel to the inner bottom surface of the sedimentation tank, which not only ensures the cleaning effect of the settled sludge during the movement of the installation frame, but also facilitates the cooperation with the roller to roll the sludge containing water.

[0020] Rollers are provided on the sides of the installation frame corresponding to the guide bars. The rollers can ensure the smooth sliding of the installation frame along the guide bars and reduce friction resistance. A telescopic push rod is tilted and fixedly connected to the top of the installation frame. The telescopic push rod can be telescoped and changed in extension length according to the usage status to avoid obstruction to the sealing of the sedimentation tank.

[0021] Preferably, a side panel is hingedly provided on the inner side of the installation frame, and the hinged side panel forms a sludge shoveling structure. A first spring is provided between the installation frame and the side panel. The side panel connected by the first spring facilitates flipping the side panel for sludge cleaning after sludge rolling, and after the sludge is cleaned, the side panel automatically resets and waits for the next use.

[0022] A rolling plate is hingedly provided on the forward side of the top of the installation frame. When the installation frame passes the roller position, the roller applies rolling action to the rolling plate to remove part of the moisture in the sludge. A discharge push block is provided on the corresponding side plate of the inner wall of the sedimentation tank. The discharge push block is hingedly provided and is tightened in one direction by a spring.

[0023] The sludge pushed by the installation frame passes through the position of the unloading push block after multi-stage rolling. When the installation frame moves in the cleaning direction, it presses against the unloading push block and pushes the spring to deform, so that the installation frame passes over the unloading push block. When the installation frame is reversed and reset, the unloading push block pushes the hinged side plate to flip the angle, which facilitates the dumping of the settled sludge.

[0024] Preferably, a scraper is sleeved on the bottom side of the mounting frame, a second spring is provided between the scraper and the mounting frame, a limiting structure is provided between the mounting frame and the scraper, and the scraper is provided at the bottom of the mounting frame through the second spring to ensure the tight contact with the bottom of the sedimentation tank, thereby ensuring the scraping effect of the sludge.

[0025] Preferably, a U-shaped block is fixedly connected to the side of the telescopic push rod, and a limit pin is inserted into the side of the U-shaped block. The limit pin penetrates the side wall of the telescopic push rod, and the extension length of the telescopic push rod is automatically positioned by the limit pin, which is convenient to use.

[0026] Preferably, the limit pin is fixedly connected to the limit block on the side near one end of the side wall of the telescopic push rod, and a third spring is provided on the side of the limit pin and is sleeved between the U-shaped block and the limit block. The limit pin tightened by the third spring automatically realizes the tightening and limiting as the telescopic push rod is stretched, which facilitates the use of the equipment.

[0027] Preferably, an operating window is hingedly provided on the side of the sealing cover plate corresponding to the drug adding bucket, and an operating handle is fixedly connected to the side of the operating window. The operating window not only facilitates the adjustment control and feeding of the drug adding bucket, but also facilitates the removal of excess air in the sedimentation tank during the aeration of sewage, thereby avoiding excessive pressurization of the sedimentation environment.

[0028] Preferably, an operating rod is fixedly connected to the side of the piston, and the operating rod extends to the outside of the sleeve at one end away from the piston. The operating rod controls the movement of the piston in the sleeve to control the pressurization of the sedimentation tank environment.

[0029] The inner bottom surface of the sedimentation tank is provided with a rolling corrugated area corresponding to the rollers. The rolling area with a corrugated structure is conducive to the rolling of sludge by the multi-stage rollers, which can effectively reduce the water content of the discharged sewage and reduce the difficulty of sludge treatment.

[0030] The inner wall of the sedimentation tank is provided with an advance groove corresponding to the roller, and a clamping spring is arranged between the roller and the inner wall of the sedimentation tank. By adjusting the clamping force of the clamping spring, the multi-level roller can exert different sizes of squeezing force on the rolled plate, which is beneficial to remove moisture from the sludge.

[0034] 3.

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The embodiment of the present invention discloses an anodic oxidation production wastewater treatment system;

[0046] According to the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a booster assembly 2 is provided above the sedimentation tank 1, the sedimentation tank 1 is sealed by the booster assembly 2, and air is filled into the sedimentation tank 1 for pressurization, thereby increasing the amount of dissolved air in the sewage, and a roller 3 is provided at the inner bottom of the sedimentation tank 1, the sludge is rolled by the roller 3 to reduce the water content of the sludge, thereby reducing the water content of the sewage discharged from the equipment.

[0047] A drug addition hopper 4 is provided above the liquid inlet end of the sedimentation tank 1, through which a neutralizer and a coagulant are added to the sewage entering the sedimentation tank 1 to adjust the pH value of the sewage to be stable, and harmful ions in the sewage are precipitated by the coagulant.

[0048] A mesh plate 5 is provided inside the sedimentation tank 1. The multi-stage mesh plate 5 is provided in the sedimentation tank 1 to reduce the flow velocity of the sewage. The sewage with a reduced flow velocity is easier to settle, thereby completing the sedimentation treatment of the sewage with a smaller equipment volume.

[0049] An aeration pipe 6 is provided at the inner bottom of the sedimentation tank 1, through which the sewage is aerated, and the booster assembly 2 is combined to increase the dissolution rate of air, so that more bubbles are rolled in the sewage, further helping the coagulation of flocs in the sewage.

[0050] A sewage pipe 7 is connected through the inner bottom of the sedimentation tank 1. The head and tail ends of the sedimentation tank 1 and the sewage pipe 7 are connected to a power pump. The power pump provides power to realize the water supply and drainage of the sedimentation tank 1. At the same time, the sludge is automatically extracted. Combined with the sludge cleaning equipment, the sedimentation tank 1 is conveniently cleaned.

[0051] According to the attached Figure 2 As shown, the booster assembly 2 includes a sealing cover plate 201 , which is hingedly disposed above the sedimentation tank 1 . The sedimentation tank 1 is sealed by the sealing cover plate 201 , and the sealing cover plate 201 also provides a working platform for workers on the sedimentation tank 1 .

[0052] A sleeve 202 is provided through the side of the sealing cover plate 201, and a piston 203 is slidably provided on the inner side of the sleeve 202. The sleeve 202 cooperates with the piston 203 to increase the pressure in the sedimentation tank 1. After the sedimentation tank 1 is sealed by the sealing cover plate 201, the air pressure in the sedimentation tank 1 is increased by pushing the piston 203. The increase in air pressure is beneficial to increasing the dissolution rate of air in the sewage, and then more tumbling bubbles are generated when the aeration pipe 6 aerates the sewage, which is beneficial to the coagulation of flocs.

[0053] An operating window 25 is hingedly provided on the side of the sealing cover plate 201 corresponding to the drug adding bucket 4, and an operating handle 26 is fixedly connected to the side of the operating window 25. The setting of the operating window 25 is not only convenient for adding materials to the drug adding bucket 4, but also convenient for maintaining the air pressure in the sedimentation tank 1 during aeration.

[0054] An operating rod 27 is fixedly connected to the side of the piston 203 , and one end of the operating rod 27 away from the piston 203 extends to the outside of the sleeve 202 .

[0055] According to the attached Figure 3 and attached Figure 4 As shown, the inner wall of the sedimentation tank 1 is fixedly connected with a mounting rail 9, the mesh plate 5 is inserted and arranged on the inner side of the sedimentation tank 1 through the mounting rail 9, the multiple layers of mesh plates 5 are arranged equidistantly and in parallel, and the side of the mesh plate 5 is fixedly connected with a limit stopper 10 corresponding to the mounting rail 9.

[0056] By installing the slide rail 9, a multi-level buffer structure is formed between the water supply and drainage ends of the sedimentation tank 1, which reduces the sewage flow rate, facilitates sewage sedimentation, and performs sewage sedimentation treatment with a smaller equipment volume. In addition, the mesh plate 5 installed by installing the slide rail 9 for easy maintenance.

[0057] The inner wall of the sedimentation tank 1 is symmetrically fixedly connected with a guide bar 11, and the inner bottom surface of the sedimentation tank 1 and the guide bar 11 are arranged as a wave structure, so as to facilitate the separation of sludge and squeezed liquid during the sludge cleaning process.

[0058] The guide bar 11 is arranged parallel to the inner bottom wall of the sedimentation tank 1. An installation frame 12 is slidably arranged on the inner side of the sedimentation tank 1 through the guide bar 11. A sludge cleaning device is installed through the installation frame 12. The settled sludge is cleaned when the installation frame 12 moves along the guide bar 11 close to the inner bottom surface of the sedimentation tank 1.

[0059] An advancement groove 28 is provided on the inner wall of the sedimentation tank 1 corresponding to the roller 3. A pressing spring is provided between the roller 3 and the inner wall of the sedimentation tank 1. When the mounting frame 12 moves along the guide bar 11, it contacts and presses against the roller 3. Extrusion occurs between the roller 3 and the mounting frame 12. The extrusion force acts on the sludge on the mounting frame 12, which is conducive to squeezing out the moisture in the sludge. The roller 3 is squeezed, and the spring on its side is compressed to advance the roller 3, thereby completing the squeezing effect of the roller 3 on the sludge.

[0060] According to the attached Figure 5 and attached Figure 6 As shown, rollers 13 are provided on the side of the installation frame 12 corresponding to the guide bar 11. The installation frame 12 moves on the guide bar 11 through the rollers 13, which not only reduces the friction between the two, but also ensures that the installation frame 12 moves smoothly along the bottom surface of the sedimentation tank 1.

[0061] The top of the installation frame 12 is tilted and fixedly connected with a telescopic push rod 14 , which facilitates telescopic adjustment to avoid obstacles to the use of the sealing cover plate 201 , and also facilitates workers to use the installation frame 12 .

[0063] A first spring 16 is provided between the mounting frame 12 and the side plate 15. The side plate 15 connected by the first spring 16 can automatically reset after being overturned and tipped over, so that the device can quickly return to the working state and continue the next use.

[0064] A rolling plate 17 is hingedly provided on the forward side of the top of the mounting frame 12. The hinged rolling plate 17 is squeezed and rotated when encountering the squeezing action of the roller 3, exerting pressure on the sludge on the side plate 15, squeezing out the water in the sludge, and reducing the water content of the sludge.

[0065] According to the attached Figure 4As shown, the inner bottom wall of the sedimentation tank 1 is provided with a discharge push block 18 corresponding to the side plate 15. The discharge push block 18 is hingedly arranged on the inner bottom surface of the sedimentation tank 1 through a spring. When the installation frame 12 is pushed to clean the sludge, the side plate 15 passes through the discharge push block 18, and the spring on its side is compressed to apply an extrusion effect to the discharge push block 18, so that the discharge push block 18 does not affect the passing of the side plate 15. When the side plate 15 moves in the reverse direction, the discharge push block 18 presses against the rear side of the side plate 15, pushing the side plate 15 to flip at an angle, thereby facilitating the dumping of the sludge into the discharge area.

[0066] The mounting frame 12 is pressed against the guide bar 11 when moving. After the sludge is poured into the discharge area on the side plate 15, the telescopic push rod 14 is lightly lifted to move the mounting frame 12 upward as a whole, directly passing over the roller 3 and other structures and returning to the initial end, but cannot directly move back to the initial position along the guide bar 11 in the reverse direction.

[0067] According to the attached Figure 6 and attached Figure 7 As shown, a scraper 19 is sleeved on the bottom side of the installation frame 12 , a second spring 20 is arranged between the scraper 19 and the installation frame 12 , and a limiting structure is arranged between the installation frame 12 and the scraper 19 .

[0068] The scraper 19 arranged at the bottom of the installation frame 12 is pressed against the inner bottom surface of the sedimentation tank 1 by the second spring 20 to scrape away the sludge, thereby ensuring the cleaning quality.

[0069] A U-shaped block 21 is fixedly connected to the side of the telescopic push rod 14. A limit pin 22 is inserted into the side of the U-shaped block 21. The limit pin 22 penetrates the side wall of the telescopic push rod 14. The extension length of the telescopic push rod 14 is positioned by the limit pin 22.

[0070] The side of the limit pin 22 near one end of the side wall of the telescopic push rod 14 is fixedly connected to the limit block 23, and a third spring 24 is provided on the side of the limit pin 22 and is located between the U-shaped block 21 and the limit block 23. The limit pin 22 provided with the third spring 24 can automatically position according to the extension of the telescopic push rod 14, which is convenient for the use of the equipment.

[0071] The anodizing production wastewater treatment system is provided with a multi-stage grid plate 5 in a sedimentation tank 1 to slow down the flow of sewage, and is combined with an aeration pipe 6 to aerate the sewage to help accelerate the coagulation and sedimentation of flocs in the sewage. In addition, a booster component 2 is provided to boost the pressure of the sedimentation environment to increase the dissolved oxygen content in the sewage, so that more bubbles are generated when the sewage rolls to help the flocs to connect and coagulate with each other, and quickly settle after being blocked by the multi-stage grid plate 5. Finally, an installation frame 12 that moves along the bottom wall of the sedimentation tank 1 is provided to cooperate with a flippable side plate 15 and a rolling plate 17 to scrape off the settled sludge and pressurize and roll it through a roller 3 to reduce the water content of the sludge, thereby reducing the water content of the discharged sewage and facilitating the treatment of the sludge.

[0072] Furthermore, the inner bottom surface of the sedimentation tank 1 is configured to be wavy, and is provided with a guide bar 11 parallel to the inner bottom surface of the sedimentation tank 1. The mounting frame 12 moves along the guide bar 11 against the inner bottom surface of the sedimentation tank 1 to facilitate the cleaning of the settled sludge. The inner bottom of the sedimentation tank 1 is provided with a roller 3 corresponding to the moving path of the mounting frame 12, and the cleaned sludge is rolled by the roller 3 to reduce the water content of the discharged sludge.

[0073] Furthermore, rollers 13 are provided on the contact surfaces of the mounting frame 12 and the guide strip 11, which not only reduces the friction between the two but also facilitates the smooth movement of the mounting frame 12 along the wavy guide strip 11. The scraper 19 pressed against the inner bottom surface of the sedimentation tank 1 by the second spring 20 is pressed against the inner bottom surface of the sedimentation tank 1 to scrape the sludge, thereby ensuring the work quality. In addition, the side plate 15 for carrying the sludge is arranged as a hinged structure, and the side plate 15 is flipped and unloaded in combination with the unloading push block 18 to realize the unloading.
