Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater synchronous purification device manufacturing technology, and in particular to a high-fluoride and high-ammonia nitrogen wastewater synchronous purification device. Background Technology
[0002] The high-fluoride and high-ammonia nitrogen wastewater simultaneous purification device is an integrated water treatment system designed for typical difficult-to-treat complex pollutants generated by industries such as electronics, electroplating, photovoltaics, fluorochemicals, and rare earth smelting. Its core application scenarios are concentrated at the end of the production line or industrial park sewage treatment plants in the above-mentioned industries. It is specifically used to treat complex acidic or alkaline wastewater with high fluoride ion concentration (usually >100mg / L), high ammonia nitrogen content, and may be accompanied by other heavy metal ions, realizing the core link of controlling specific industrial pollution sources from the source. In existing purification devices, uneven mixing of chemical reagents and wastewater during the addition of reagents can easily occur, leading to a significant waste of chemical reagents and greatly increasing production costs. Furthermore, the traditional method of adding chemical reagents at a fixed rate means that different volumes of wastewater are purified with the same chemical reagents, which can result in either waste or poor purification effects, thus hindering the purification of wastewater. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by setting up a rotating tube for discharging chemical reagents, allows the chemical reagents to rotate during the discharge process, fully combining with the wastewater. Furthermore, under the action of the stirring plate, the chemical reagents come into more thorough contact with the wastewater, accelerating the chemical reaction between the two. 2.

Detailed Implementation
[0013] Reference Figures 1-4A simultaneous purification device for high-fluoride and high-ammonia-nitrogen wastewater includes a purification tank 1 and a purification assembly fixedly connected to the purification tank 1. The purification tank 1 has an inlet 8 on its upper side, through which wastewater enters. A ring screen 9 is fixedly connected to the lower side of the purification tank 1, and the purified wastewater is ultimately discharged through the ring screen 9. The purification assembly includes a filter chamber 20 fixedly connected to the lower side of the purification tank 1, with multiple filter plates 21 slidably connected within the filter chamber 20. These specialized filter plates 21 are mainly composed of a porous support substrate (such as PP / PE plastic or stainless steel) and a surface-loaded active adsorption / catalytic coating (such as hydroxyapatite, modified alumina, or lanthanide metal composite materials). When wastewater containing fluoride (F⁻) and ammonia nitrogen (NH₄⁺ / NH₃) flows through with chemical reagents, the coating specifically captures fluoride ions (generating fluorapatite, etc.) through chemical adsorption, ion exchange, or co-precipitation, and synergistically adsorbs / catalyzes the degradation of ammonia nitrogen and its reaction products (such as calcium and magnesium salt precipitates), achieving simultaneous interception and separation of pollutants. This is a novel approach in existing wastewater treatment systems. The technology is not described in detail. Each filter plate 21 has a handle 22 fixedly connected to one side, and a motor 2 is fixedly connected to one side of the purification tank 1. The motor 2 is mainly composed of an AC asynchronous motor body, a liquid level / flow sensor and a variable frequency speed controller. The sensor monitors the flow rate or liquid level of the wastewater entering the purification tank in real time and converts it into an electrical signal and sends it to the controller. The controller dynamically adjusts the power frequency output to the motor 2 according to the preset ratio, thereby precisely controlling the speed of the motor 2 and achieving automatic matching that the more wastewater enters, the faster the speed. This is existing technology and will not be described in detail. The output end of the motor 2 is fixedly connected to a first gear 3. A rotating tube 5 is rotatably passed through the purification tank 1. Multiple connecting holes 6 are opened on the rotating tube 5. Multiple stirring plates 7 are fixedly connected to the outside of the rotating tube 5. A second gear 4 is fixedly connected to one side of the rotating tube 5. The first gear 3 and the second gear 4 mesh with each other. A storage tank 13 is fixedly connected to one side of the purification tank 1. A connecting pipe 16 is fixedly connected to the upper side of the storage tank 13. The connecting pipe 16 and the rotating tube 5 are rotatably connected. A connecting plate 14 is fixedly connected to one side of the storage tank 13, and a filling port is fixedly connected to the other side of the storage tank 13. The chemical substances stored in the storage tank 13 are replenished through the filling port. The core components of the chemical substances are usually calcium salts (such as calcium chloride and lime), magnesium salts (such as magnesium chloride and magnesium sulfate), and phosphates (such as disodium hydrogen phosphate). In the wastewater, they react chemically to form calcium fluoride precipitate by combining with fluoride ions, and magnesium ammonium phosphate (struvite) precipitate by combining with ammonia nitrogen and phosphate ions, thereby achieving simultaneous removal. A sliding rod 15 is slidably connected to the storage tank 13, and a pressure plate 17 is fixedly connected to the lower side of the sliding rod 15. The sliding rod 15 and the connecting plate 14 are fixedly connected by a spring 18. A rotating shaft 11 is rotatably connected to the outer shell of the purification tank 1. A third gear 10 is fixedly connected to one side of the rotating shaft 11. The third gear 10 meshes with the second gear 4. Multiple protruding rods 12 are fixedly connected to one side of the rotating shaft 11, and a short rod 19 is fixedly connected to one side of the sliding rod 15. The protruding rods 12 and the short rods 19 are positioned opposite each other.
[0014] In this invention, when wastewater needs to be purified, the wastewater first enters the purification tank 1 through the inlet 8. The motor 2 is started, and the motor 2 drives the first gear 3 to rotate. The first gear 3 drives the second gear 4 to rotate, and the second gear 4 drives the rotating tube 5 to rotate. The rotating tube 5 drives the connecting hole 6 and the stirring plate 7 to rotate. The second gear 4 drives the third gear 10 to rotate, and the third gear 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives multiple protruding rods 12 to rotate. The protruding rods 12 continuously abut against the short rods 19. The short rods 19 drive the sliding rod 15 to move up and down under the action of the spring 18. The sliding rod 15 drives the pressure plate 17 to move up and down, continuously squeezing the chemical reagents in the storage tank 13. After being squeezed, the chemical reagents enter the rotating tube 5 through the connecting tube 16, and then enter the purification tank 1 through the connecting hole 6 on the rotating tube 5. After the wastewater and chemical reagents come into full contact, they are adsorbed and filtered through the filter plate 21, and finally flow out through the ring screen 9. The filter plate 21 can be periodically removed and replaced by the handle 22.
