Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically, it relates to a wastewater hydrolysis acidification tank for wastewater treatment. Background Technology

[0002] Acidification tanks can be used to add appropriate amounts of acidic substances (such as hydrochloric acid, sulfuric acid, etc.) to lower the pH value of dichlorophenyl ether wastewater to the required range. In the organic chemical production of dichlorophenyl ether, a certain amount of sludge is generated after treatment in the wastewater acidification tank. This is because during the acidification process, acidic substances are added to the wastewater, reacting with organic matter, suspended solids, or other solid pollutants, causing them to aggregate and precipitate.

[0003] Publication (Announcement) No.: CN221971370U discloses a wastewater treatment hydrolysis acidification tank, including a tank body. An upper slide plate and a lower slide plate are slidably installed between the inner walls of both sides of the tank body. A sedimentation perforated plate is fixedly installed in the tank body near the bottom of the lower slide plate. Multiple first rotating rods are rotatably installed between the upper slide plate and the lower slide plate. Several stirring blades are evenly fixedly installed on the outer peripheral wall of the first rotating rods. Two sets of scraping brush assemblies are installed at the bottom of the lower slide plate. The scraping brush assemblies are used to scrape the sedimentation perforated plate in conjunction with the reciprocating motion of the lower slide plate in the tank body. This application uses the reciprocating motion of the lower slide plate in the tank body to drive multiple rotating and connected first brush plates to open and close at the top of the sedimentation perforated plate, thereby enabling the multiple first brush plates to drive the brushes at their bottoms to scrape the sludge settled on the sedimentation perforated plate, improving the sludge discharge efficiency at the bottom of the tank body.

[0004] Existing wastewater treatment methods are ineffective at breaking down impurities in wastewater, have limited options, and are not efficient in acidification.

[0005] To address the aforementioned issues, this application proposes a wastewater hydrolysis acidification tank for wastewater treatment. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a wastewater hydrolysis acidification tank for wastewater treatment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A wastewater hydrolysis acidification tank for wastewater treatment includes a treatment tank with four supporting legs at the bottom. A wastewater diversion mechanism is installed on the left side of the treatment tank. From left to right, a guide plate mechanism, a first intercepting triangular seat, and a second intercepting triangular seat are arranged inside the treatment tank. A discharge bend is provided on the right side of the treatment tank. A sewage discharge hole is opened at the bottom of the treatment tank, and a conical cylinder is installed inside the sewage discharge hole.

[0009] Preferably, the sewage diversion mechanism includes a diversion cylinder, which is fixedly installed on the left side of the treatment tank. A sewage inlet pipe is connected to the top side of the diversion cylinder, and a vertical pipe is connected to the bottom side of the diversion cylinder. The vertical pipe is located inside the treatment tank. A sealing plate is provided on the right side of the treatment tank. A motor is fixedly installed on the left side of the diversion cylinder. A rotating rod is installed on the output shaft of the motor. The rotating rod is rotatably installed inside the diversion cylinder through a bearing. A spiral blade is installed on the outside of the rotating rod. The spiral blade is located inside the diversion cylinder.

[0010] Wastewater enters the guide cylinder through the wastewater inlet pipe. The motor drives the rotating rod to rotate, which in turn drives the spiral blade to rotate. The spiral blade guides the wastewater, increasing the flow rate. The spiral blade also crushes large particles of impurities in the wastewater. The wastewater then flows into the treatment tank through the vertical pipe.

[0011] Preferably, the guide plate mechanism includes a base, which is installed on the bottom inner wall of the treatment tank. An arc-shaped hole is provided on the base, and a rotating column is rotatably installed in the arc-shaped hole. A guide plate is fixedly installed on the outer side of the rotating column, and the two sides of the guide plate are slidably and sealingly connected to the inner wall of the treatment tank.

[0012] By using a guide plate to block the sewage, impurities in the sewage slide down the side of the guide plate. The side of the guide plate near the drain hole can guide the impurities to the location of the drain hole.

[0013] Preferably, synchronous motors are fixedly installed on both sides of the treatment pool, and the output shafts of the two synchronous motors are rotatably installed with the treatment pool. The output shafts of the two synchronous motors are fixedly installed at both ends of the rotating column.

[0014] Two synchronous motors drive the rotating column to rotate, which rotates within the arc-shaped hole, allowing adjustment of the angle at which the guide plate blocks the sewage.

[0015] Preferably, a biofilm carrier is mounted on the inclined surface of the first intercepting triangular seat, and the surface of the biofilm carrier is loaded with polyvinyl alcohol and enriched with acid-producing bacteria.

[0016] Biofilm carriers are used for wastewater acidification treatment.

[0017] Preferably, the inclined surface of the second intercepting triangular seat is provided with three intercepting grooves at equal intervals, and the three intercepting grooves are sequentially provided with sludge intercepting nets, active microorganisms and sedimentation inert materials.

[0018] The three interception channels set on the inclined surface of the second interception triangular seat are used for sludge interception, microbial degradation, and stain sedimentation of sewage.

[0019] Preferably, the conical cylinder includes a drain pipe, which is fixedly installed with a drain hole. The bottom of the drain pipe is connected to a solenoid valve, which is equipped with a [missing information].

[0020] The sludge flows into the drain pipe through the impurity inlet. When the inlet is opened intermittently, the sludge can be discharged through the solenoid valve.

[0021] In summary, the technical effects and advantages of this utility model are as follows:

[0022] 1. Integrated crushing and flow guiding: The rotating design of the spiral blade assembly (motor + rotating rod + spiral blade) achieves dual functions: accelerating sewage flow: the spiral blades forcefully guide the flow, shortening the sewage retention time and preventing siltation; and pulverizing particulate matter: mechanically cutting large particles (such as fibers and suspended solids), reducing the load on subsequent treatments and preventing pipe blockage. The vertical layout of the vertical pipe and flow guide ensures that sewage enters the treatment tank in a fixed direction, avoiding turbulent water flow that could affect the efficiency of the hydrolysis and acidification reaction.

[0023] 2. Adjustable angle guide: A synchronous motor drives a rotating column to rotate within an arc-shaped hole. The tilt angle of the guide plate can be adjusted in real time to adapt to different wastewater flow rates and impurity concentrations.

[0024] Optimized impurity separation: When the side of the guide plate is aligned with the drain hole, the path for impurities to slide down is the shortest, thus improving sludge discharge efficiency.

[0025] Sealed sliding design: The sealing structure between the guide plate and the pool wall prevents sewage from flowing around and ensures that all sewage passes through the biofilm treatment zone.

[0026] The synchronous motors on both sides ensure the symmetry and stability of the guide vane adjustment, preventing wear and tear caused by unilateral force.

[0027] 3. The biofilm carrier of the first intercepting triangular seat uses polyvinyl alcohol (PVA) to immobilize acid-producing bacteria (such as propionic acid bacteria and acetic acid bacteria). Advantages include: High specific surface area: The rough and porous surface of the carrier increases the bacterial colony attachment density by 3-5 times. Doubled acidification efficiency: Direct addition of propionic acid and acetic acid shortens the acidification cycle, and the conversion rate of dissolved organic matter (SCOD) increases by 20%-30%.

[0028] 4. The three-stage interception tank of the second intercepting triangular seat achieves step-by-step purification: Sludge interception net: intercepts residual suspended solids and prevents sludge loss. Active microbial layer: replenishes facultative bacteria and degrades insoluble organic matter. Inert sedimentation zone: adsorbs heavy metal ions and colloidal particles, reducing effluent turbidity.

[0029] 5. The conical cylinder is linked to the sewage pipe via a solenoid valve, supporting timed or pressure-sensing sludge discharge: Anti-clogging design: The conical structure reduces dead corners for sludge accumulation, and the solenoid valve opens and closes quickly to avoid secondary sludge buildup. Intermittent sludge discharge reduces energy consumption, and the sludge moisture content can be controlled below 85%.

[0030] This invention utilizes an integrated process of flow guidance, crushing, acidification, interception, and sludge discharge, resulting in multi-stage wastewater treatment and superior treatment effectiveness. It achieves the following breakthroughs: Increased treatment efficiency: The combination of spiral blade crusher and biofilm carrier enables COD removal rates exceeding 60%. Reduced operation and maintenance costs: Dynamic flow guide plates and an intelligent sludge discharge system reduce the frequency of manual intervention, saving 15%-20% in energy consumption. Enhanced adaptability: The modular structure allows for expanded treatment capacity, adapting to the diverse needs of industrial and domestic wastewater. Attached Figure Description

[0044] Wastewater enters the guide tube 21 through the wastewater inlet pipe 22. The rotating rod 24 is driven to rotate by the motor 23, which in turn drives the spiral blade 25 to rotate. The spiral blade 25 guides the wastewater and increases the flow rate of the wastewater. The spiral blade 25 crushes large particles of impurities in the wastewater. The wastewater flows into the interior of the treatment tank 1 through the vertical pipe 26.

[0045] Reference Figure 5 In this embodiment, the guide plate mechanism 3 includes a base 34, which is installed on the bottom inner wall of the treatment tank 1. An arc-shaped hole 35 is provided on the base 34, and a rotating column 32 is rotatably installed in the arc-shaped hole 35.

Synchronous motors 33 are fixedly installed on both sides of the treatment tank 1. The output shafts of the two synchronous motors 33 are rotatably installed with the treatment tank 1. The output shafts of the two synchronous motors 33 are fixedly installed at both ends of the rotating column 32.

[0046] The guide plate 31 blocks the sewage, and the impurities in the sewage slide down along the side of the guide plate 31. The guide plate 31 is close to the side of the sewage discharge hole 12, which can guide the impurities to the position of the sewage discharge hole 12. The rotating column 32 is driven to rotate by two synchronous motors 33. The rotating column 32 rotates in the arc hole 35, which can adjust the angle of the guide plate 31 blocking the sewage.

[0053] Working principle: Wastewater enters the guide cylinder 21 through the wastewater inlet pipe 22. The motor 23 drives the rotating rod 24 to rotate, which in turn drives the spiral cutter 25 to rotate. The spiral cutter 25 guides the wastewater, increasing its flow rate. The spiral cutter 25 also crushes large particles of impurities in the wastewater. The wastewater flows into the treatment tank 1 through the vertical pipe 26. The guide plate 31 blocks the wastewater, causing impurities to slide down its sides. The guide plate 31, near the drain hole 12, guides the impurities into the drain hole 12, where they flow into the drain pipe 61. The drain pipe 63 opens intermittently, allowing sludge to be discharged through the solenoid valve 62. When the blocking angle of the guide plate 31 needs adjustment, it is driven by two synchronous motors 33. The rotating column 32 rotates within the arc-shaped hole 35, which can adjust the angle of the guide plate 31 blocking the sewage. The sewage flows into the space between the guide plate mechanism 3 and the first intercepting triangular seat 4. The surface of the biofilm carrier 41 is loaded with polyvinyl alcohol and enriched with acid-producing bacteria. The biofilm carrier 41 is used to acidify the sewage. During the acidification process, propionic acid and acetic acid are added in a ratio of 4:5. After acidification, the sewage enters the space between the first intercepting triangular seat 4 and the second intercepting triangular seat 5. The three intercepting tanks 51 are sequentially equipped with sludge interception nets, active microorganisms, and sedimentation inert materials. The three intercepting tanks 51 on the inclined surface of the second intercepting triangular seat 5 are used for sludge interception, microbial degradation, and stain sedimentation of the sewage. Finally, the sewage is discharged through the discharge bend 11.
