Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a treatment system and method for aluminum oxidation wastewater. Background Art

[0002] With the development of aluminum processing industry, aluminum surface treatment has become an indispensable and important link in the aluminum processing process, and aluminum surface treatment process technology is a relatively complex process involving various types of chemical raw materials, the most important harmful ones include aluminum, acid, ammonia nitrogen, COD, etc. At present, a large amount of aluminum ions are produced in the aluminum oxidation process, and aluminum oxidation wastewater is often directly flowed into the regulating tank together with other ordinary wastewaters, and the aluminum therein is not treated separately. On the one hand, the aluminum content in the aluminum oxidation wastewater exceeds the standard and pollutes the environment. On the other hand, the aluminum oxidation wastewater directly enters the regulating tank, causing a large amount of sludge to be produced in the regulating tank, affecting the regulating function of the regulating tank. The sludge in the regulating tank needs to be frequently treated, and the sludge in the regulating tank is difficult to treat. When the aluminum oxidation wastewater and other wastewaters enter the next step of treatment together, the difficulty of treatment is increased. With the advancement of industrialization, the discharge of various types of high-concentration and complex industrial wastewaters continues to increase. The existing wastewater treatment process has exposed a series of deficiencies in application, which restricts the further improvement of treatment efficiency and effect.

[0003] In existing industrial wastewater treatment technologies, the removal of large particle impurities usually relies on simple physical separation methods such as sedimentation and screens. Due to differences in specific gravity, shape and water flow characteristics, large particle impurities are easily deposited or retained during the physical separation process, causing equipment blockage or unstable operation. Subsequent problems caused by this include reduced sewage flow control accuracy, increased equipment cleaning frequency and reduced treatment efficiency.

[0004] The existing technology for cleaning and discharging sludge mainly relies on manual cleaning or passive sludge discharge systems. The inner wall and bottom of the tank are the main areas for sludge deposition. The traditional cleaning method is incomplete due to the complex tank structure and the strong cohesion of the deposited sludge, and even requires frequent shutdowns for maintenance. In addition, the sewage inside the tank is unevenly stirred after the sludge accumulates, which further leads to a decrease in treatment efficiency. Summary of the invention

[0033] Please see attached Figure 1 - Attachment Figure 3The embodiment of the present invention provides a treatment system and method for aluminum oxidation wastewater, comprising: a tank body 1, the top of which is connected to a top cover 2 by bolts; a crushing and feeding component 3, which is arranged on the top cover 2 and is used to crush large particles of impurities in the sewage; a stirring component 4, which is arranged inside the tank body 1 and is used to stir the sewage inside the tank body 1; a temperature control component 5, which is arranged on the outer wall of the tank body 1 and is used to assist in purifying the sewage; a filtering component 6, which is arranged at the bottom of the tank body 1 and is used to filter the sewage after pH adjustment again; the crushing and feeding component 3 includes a hopper 301, the outer wall of which is fixed to the top cover 2 At the top of the top cover 2, a motor 302 is fixed on the upper surface of the top cover 2, a gear 303 is fixed on the output end of the motor 302, a gear 304 is rotated on the outer wall of the hopper 301, the gear 303 and the gear 304 are meshed, and a crushing roller 305 is fixed inside the gear 303 and the gear 2 304, the outer wall of the crushing roller 305 rotates inside the hopper 301, a transmission pulley 306 is fixed to the end of the crushing roller 305, a rotating rod 307 is fixed to the other end of the transmission pulley 306, a material guide box 308 is fixed inside the rotating rod 307, and the outer wall of the material guide box 308 is arranged inside the hopper 301.

[0034] Specifically, the crushing and feeding component 3 realizes the preliminary treatment of sewage through the hopper 301. The outer wall of the hopper 301 is fixed to the top of the top cover 2, which ensures the stability of the component and the smooth entry of sewage. A motor 302 is fixed on the upper surface of the top cover 2. The motor 302 drives the rotation of the gear 1 303 through its output end. At the same time, the gear 1 303 is meshed with the gear 2 304 rotatably arranged on the outer wall of the hopper 301, forming an efficient transmission system. The inside of the gear 1 303 and the gear 2 304 are fixed with crushing rollers 305. When the gear system drives the crushing roller 305 to rotate, the outer wall of the crushing roller 305 rotates at a high speed inside the hopper 301, and the large particles of impurities carried in the sewage are fully crushed, so that these impurities are broken into smaller particles. The crushed sewage and impurities are transferred to the rotating rod 307 under the action of the transmission pulley 306, and a guide box 308 is fixed inside the rotating rod 307. The outer wall of the guide box 308 is arranged inside the hopper 301. Through the precise guidance of the guide box 308, the crushed sewage can stably flow into the tank body 1. This structural design ensures the controllability of the sewage flow and the efficient treatment of large-particle impurities, effectively solves the problems of unstable equipment operation and increased load of the subsequent filter component 6 caused by impurity blockage in the traditional wastewater treatment process, and reduces the maintenance cost and operation complexity, providing a solid basic support for the efficient operation of the entire wastewater treatment system.

[0035] Please see attached Figure 5 - Attachment Figure 7The stirring assembly 4 includes a motor 2 401, a reducer 402 is fixed to the driving end of the motor 2 401, the lower surface of the reducer 402 is fixed to the upper surface of the top cover 2, a rotating rod 2 403 is fixed to the output end of the reducer 402, a plurality of stirring rods 404 are fixed to the outer wall of the rotating rod 2 403, a connecting rod 405 is fixed to the outer wall of the stirring rod 404, a connecting block 406 is fixed to the outer wall of the stirring rod 404 and the connecting rod 405, a scraper 407 is connected to the inside of the connecting block 406 by bolts, a feed pipe 7 is passed through the bottom end of the tank body 1, a storage box 8 is fixed to the top end of the feed pipe 7, a valve 9 is arranged inside the feed pipe 7, a sludge pump 10 is fixed to the outer wall of the tank body 1, an extraction pipe 11 is fixed to the input end of the sludge pump 10, the outer wall of the extraction pipe 11 passes through the interior of the tank body 1, and a discharge pipe 12 is fixed to the output end of the sludge pump 10.

[0036] Specifically, the stirring component 4 is driven by the motor 2 401, and a reducer 402 is connected and fixed to the driving end thereof. The reducer 402 adjusts the rotation speed to make the stirring process smoother and suitable for treating sewage of different concentrations and viscosities. The lower surface of the reducer 402 is firmly fixed to the upper surface of the top cover 2 to ensure the stability and operational reliability of the overall component. The output end of the reducer 402 is fixedly connected to the rotating rod 2 403, and a plurality of stirring rods 404 are evenly distributed on the outer wall of the rotating rod 2 403. The layout of these stirring rods 404 can achieve comprehensive stirring of the sewage inside the tank body 1, thereby avoiding the problem of sedimentation or decreased treatment effect caused by uneven stirring. A connecting rod 405 is also fixed to the outer wall of the stirring rod 404. The connecting rod 405 and the outer wall of the stirring rod 404 are respectively connected to the scraper 407 through the connecting block 406. This design allows the stirring rod 404 to stir the sewage while the scraper 407 can scrape off the sewage attached to the inner wall and bottom of the tank body 1. The sludge at the bottom is collected and concentrated to the position of the extraction pipe 11. The feeding pipe 7 at the bottom of the tank body 1 is connected to the storage box 8. The hydrochloric acid contained in the storage box 8 is injected into the tank body 1 through the feeding pipe 7. The flow rate is accurately controlled by the valve 9 arranged inside the feeding pipe 7, so as to realize the accurate adjustment of the pH value of the sewage. The sludge pump 10 fixed on the outer wall of the tank body 1 extracts the sludge at the bottom through the extraction pipe 11. The efficient operation of the sludge pump 10 can discharge the sludge from the outside of the tank body 1 through the discharge pipe 12 connected to its output end. Such a design not only avoids the decline in treatment efficiency caused by long-term accumulation of sludge in traditional equipment, but also effectively reduces the equipment maintenance frequency and manual cleaning cost. At the same time, through the linkage between the stirring component 4 and the sludge cleaning function, the cleanliness of the inside of the tank body 1 and the continuity of sewage treatment can be ensured, providing the system with a more efficient and stable operation effect, and overcoming the problem that traditional wastewater treatment equipment is easy to be blocked and unstable in operation under complex working conditions.

[0038] Specifically, the temperature control component 5 realizes dynamic adjustment of the sewage temperature inside the tank body 1 through the jacket 501. The jacket 501 is tightly fixed to the outer wall of the tank body 1 to ensure the high efficiency of heat transfer. The outer wall of the jacket 501 is connected to the water tank 502. The left-right symmetrical heating wires 503 installed inside the water tank 502 can evenly heat the water in the water tank 502. The heated hot water is pumped by the water pump 504 and transported to the drain pipe 506 through the pumping pipe 505, and then injected into the jacket 501 to form a circulation. At the same time, the reflux pipe 507 arranged inside the jacket 501 recirculates the hot water. The new water is guided back into the water tank 502 to form a continuous closed-loop circulation heating system. This design ensures that the sewage temperature is always maintained in an appropriate range during the treatment process, thereby improving the rate and uniformity of chemical reactions such as pH adjustment and avoiding the problem of decreased reaction efficiency due to temperature fluctuations. The sealing cover 508 slidingly arranged on the top of the water tank 502 not only has a sealing effect, but the filter screen 509 fixed at its bottom can also perform preliminary filtration on the water inside the water tank 502 to prevent the jacket 501 and the water pump 504 from affecting the heating efficiency or equipment life due to impurities deposition during the circulation process.

[0039] The filter assembly 6 is connected to the bottom of the tank body 1 through a connecting pipe 601 to achieve deep filtration of the sewage. After the sewage enters the filter box 602 through the connecting pipe 601, it first passes through the internal sliding filter screen 603 for physical filtration of solid particles. The filter screen 603 intercepts suspended matter and particulate matter in the sewage, and the activated carbon plate 604 further adsorbs organic matter, odor and soluble pollutants in the sewage. The sealing plate 605 fixed on the outer wall of the filter screen 603 and the activated carbon plate 604 ensures the airtightness of the filtration process. At the same time, the bottom of the filter box 602 discharges the treated clean water through the discharge pipe 606. The solenoid valve 607 set inside the connecting pipe 601 and the discharge pipe 606 can accurately control the inflow and outflow flow of sewage, thereby In order to ensure the stability of the filtration process, a motor 3 608 is fixed to the outer wall of the filter box 602. The motor 3 608 drives multiple cams 610 to rotate through a rotating rod 609 connected to its output end. The cam 610 forms a vibration cleaning mechanism with the filter screen 2 603 through periodic contact, which removes blockages on the filter screen and extends its service life, further improving the operating efficiency and stability of the filter component 6. The linkage design of the temperature control component 5 and the filter component 6 not only effectively improves the wastewater treatment capacity and deep purification effect, but also solves the problem of reduced treatment efficiency caused by temperature fluctuations and blockage of the filter component 6 in traditional systems, while greatly reducing the equipment maintenance frequency and operating costs, providing strong support for the continuity and reliability of wastewater treatment.

The sludge is then extracted by a sludge pump (10), and the cleaned sludge is discharged from the tank body (1) through a discharge pipe (12), thereby ensuring the cleanliness of the interior of the tank body (1) and the stable operation of the system. In order to improve the treatment efficiency, a temperature control component (5) is installed on the outer wall of the tank body (1). The temperature control component (5) includes a jacket (501) and a water tank (502). A heating wire (503) is installed inside the water tank (502). The water in the water tank (502) is heated by the heating wire (503). The heated hot water is pumped out by a water pump (504) through a water pump pipe (505) and injected into the jacket (501) through a drain pipe (506). The jacket (501) is connected to the water pump (504). The circulating hot water realizes dynamic temperature control of the sewage in the tank (1) to stabilize the rate and efficiency of the pH adjustment reaction. At the same time, the reflux pipe (507) in the jacket (501) circulates the hot water back to the water tank (502). The top of the water tank (502) is provided with a sealing cover (508). The bottom of the sealing cover (508) is installed with a filter screen (509). The filter screen (509) filters impurities in the circulating water to protect the operation of the jacket (501) and the water pump (504). After being temperature-controlled, the sewage flows into a filter assembly (6) disposed at the bottom of the tank (1). The filter assembly (6) comprises a connecting pipe (601) and a filter box (602). After the sewage enters the filter box (602), a filter screen (603) and an activated carbon plate (604) slidingly disposed inside the filter box (602) perform deep filtration on suspended solids, heavy metals and organic matter in the sewage. The filter screen (603) and the activated carbon plate (604) are fixed in the filter box (602) via a sealing plate (605). At the same time, the motor three (608) drives the plurality of cams (610) to rotate through the rotating rod (609). The movement of the cams (610) vibrates and cleans the filter screen two (603), thereby preventing the filter screen (603) from being blocked and extending the service life of the activated carbon plate (604). Finally, the filtered sewage is discharged from the discharge pipe (606) at the bottom of the filter box (602). The electromagnetic valve (607) installed inside the connecting pipe (601) and the discharge pipe (606) accurately controls the inflow and discharge process of the sewage.
