Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a sulfuric acid wastewater treatment device. Background Technology

[0002] In the process of urban wastewater treatment, testing is a core link to ensure treatment effectiveness, monitor pollutant removal rate and ensure discharge compliance. The testing content covers three major categories: water quality, sludge and process operation parameters. The indicators, methods and frequencies should be selected according to national standards, local regulations and actual needs.

[0003] Chinese Publication No. CN108328784A discloses a device and method for treating sodium sulfate-containing wastewater. The device includes a synthesis reaction tank, a synthesis settling tank, a refining reaction tank, a refining settling tank, a brine tank, a calcium sulfate filter press, a salt mud filter press, a calcium sulfate feed pump, and a salt mud pump. These components are sequentially connected. The refining settling tank is connected to the salt mud filter press via the salt mud pump. The filtrate outlet of the salt mud filter press is connected to the circulating liquid inlet of the refining reaction tank. The synthesis settling tank is connected to the calcium sulfate filter press via the calcium sulfate feed pump. The filtrate outlet of the calcium sulfate filter press is connected to the circulating filtrate inlet of the synthesis reaction tank. A stirring device is installed in both the synthesis settling tank and the refining settling tank. The invention also discloses a method for treating sodium sulfate-containing wastewater using the above-mentioned device. This invention has the advantages of simple structure, low cost, convenient operation, good treatment effect, and energy saving and environmental protection.

[0004] Although the above patent uses components such as stirring device, multiple tanks and salt mud filter press to treat wastewater, it is necessary to consider that when adding drugs during the treatment of sulfuric acid wastewater, a large amount of flocculent material will be generated.

[0039] like Figures 7-8 As shown, a transmission chamber 322 is rotatably connected to the bottom of the adjusting disc 32. The lower end of the telescopic rod 333 passes through the adjusting disc 32 and is fixedly connected to the transmission chamber 322. A partition 3221 is fixedly connected to the inner side of the transmission chamber 322. A disc motor 34 is fixedly connected to one side of the partition 3221. A first rotating wheel 341 is fixedly connected to the output end of the disc motor 34. A first gear 3411 is fixedly connected to the end of the first rotating wheel 341 away from the disc motor 34. One side of the first gear 3411 is meshed with... There is a second gear 35, and a second rotating wheel 351 is fixedly connected to one side of the second gear 35. A sliding strip 36 is provided between the first rotating wheel 341 and the second rotating wheel 351. The outer walls of both sides of the sliding strip 36 are in contact with the outer walls of the first rotating wheel 341 and the second rotating wheel 351. A sliding plate 361 is fixedly connected to the bottom of the sliding strip 36. The sliding plate 361 is located below the transmission chamber 322. Both ends of the sliding plate 361 are in contact with the inner wall of the separation chamber 1. Two openings are formed on the middle surface of the sliding plate 361. Sliding holes 3611 and 3611 are connected to sliders 37 and 39. A stirring rod 3612 is fixedly connected to the bottom center of the sliding plate 361. The length of the stirring rod 3612 matches the inlet of the flow pipe 151. Extension rods 371 are fixedly connected to both sides of slider 37. Sliding rods 372 are slidably connected to the outer wall of extension rods 371. A telescopic connecting rod 373 is rotatably connected to the top of slider 372. At the end furthest from the second slider 372, the extension rod 371 is rotatably connected above the second strip hole 3611 on the sliding plate 361. A horizontal column 374 is fixedly connected to the side of the extension rod 371 furthest from the sliding plate 361. A scraper 38 is fixedly connected to the end of the horizontal column 374 furthest from the extension rod 371. The scraper 38 is ring-shaped. Buoyancy balls 391 are fixedly connected to both sides of the third slider 39. A sliding block 392 is fixedly connected to the top of the third slider 39. The top of the sliding block 392 fits into the first slider 37.

[0040] Therefore, when sulfuric acid wastewater needs to be treated, such as... Figures 3-6 As shown, after the staff connects the inlet 141 to the external sewage discharge equipment, the work begins. At this time, the wastewater enters the inlet chamber 2 from the inlet 141 and gradually flows towards the inlet pipe 31 in the center. At this time, the detection piece 332 at the inlet of the inlet pipe 31 performs preliminary detection. When the wastewater reaches the limiting plate 331 at the middle of the sliding rod 33, as the wastewater increases, the water pressure gradually increases, which will squeeze the middle limiting plate 331 to move downward and gradually slide downward to the position of the limiting ring 312 and fix it. At this time, the wastewater will gradually flow out from the first arched hole 311 into the separation chamber 21 and stay briefly on the regulating plate 32. At this time, the regulating plate 32 is used to add the required pH value of the drug to the wastewater from the first drug inlet 11 to adjust the pH value of the wastewater flowing to this point to the range of 8.5-9.5. Then, it flows from the second arched hole 321 on the outside of the regulating plate 32 into the mixing chamber 22.

[0041] When the wastewater flows into the mixing chamber 22, the servo motor 142 is started. Driven by the servo motor 142, the sliding rod 33 and the telescopic rod 333 together drive the transmission chamber 322 to rotate. The transmission chamber 322 will drive the sliding plate 361 at its bottom to rotate. At this time, the sliding plate 361 drives the stirring rod 3612 to rotate, which fully stirs the wastewater that has flowed into the mixing chamber 22 and the medicine added in the second medicine inlet 12, and makes the wastewater form flocculent matter in the mixing chamber 22. The stirring rod 3612 cleans the position of the flow pipe 151, causing the flocculent matter to flow around the isolation plate 15. After a certain period of sedimentation, the wastewater will first flow out from the position of the surrounding filter screen 152, while the flocculent matter will be blocked by the filter screen 152 and remain in the filter screen 152.

[0042] It should be noted that polyferric sulfate can be added as a flocculant to the No. 2 inlet 12 to aggregate the particles in the wastewater into large flocs, thereby further removing residual sulfate ions.

[0043] Driven by the disc motor 34, the first rotating wheel 341 rotates, which in turn drives the first gear 3411 to rotate. The first gear 3411 then drives the second gear 35 and the second rotating wheel 351 on one side to rotate. During the rotation of the first rotating wheel 341 and the second rotating wheel 351, the sliding strip 36 and the sliding plate 361 between them move upward a short distance. At this time, as the sliding plate 361 moves upward, the stirring rod 3612 moves upward a short distance. During the upward movement and rotation of the stirring rod 3612 and the sliding plate 361, the flocculent material settled at the bottom is stirred by the stirring rod 3612 and moved to the periphery. At this time, the wastewater flows from the flow pipe 151 into the discharge chamber 23. As mentioned above, the flocculent material will eventually remain in the filter screen 152. This achieves the separation of wastewater and flocculent material after drug treatment.

[0044] It should be noted that during the up-and-down movement of the sliding plate 361, the stirring rod 3612 driven by it also moves up and down to fully stir and mix the wastewater and medicine to different degrees. As the sliding plate 361 moves up and down, the upper and lower limits of the distance that the scraper 38 can move up and down will also change.

[0045] In addition, when the flow rate is large or small, the sliding rod 33 terminal limiting plate 331 is pushed down by different water pressures, and at the same time the telescopic rod 333 is contracted to form the size of the opening of the first arched hole 311. This can be coordinated with the subsequent separation of flocculents and wastewater at the bottom of the separation chamber 1 by the rise of the partition 3221 to make the wastewater feed and discharge uniform.

[0046] In addition, as the water level changes, the buoyancy ball 391 will move up and down together. At this time, the up and down movement of the buoyancy ball 391 will also drive the third slider 39 and the sliding block 392 to move up and down together. At this time, the sliding block 392 will also drive the first slider 37 to move up and down. At this time, the first slider 37 and the scraper 38 move up and down together to clean the attached flocculent matter and debris on the inner wall of the separation chamber 1. The telescopic connecting rod 373 is a component that limits the upper and lower limits of the movement of the scraper 38.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
