Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides, for example Figure 1-5The diagram shows a corrosion-resistant wastewater pipeline treatment device, comprising a pipeline treatment tank 3 and a right end plate 1 located at the right end of the pipeline treatment tank 3. A left end plate 5 is located at the left end of the pipeline treatment tank 3. Sealing flanges are provided on the exterior of both the right and left ends of the pipeline treatment tank 3, and both the left end plate 5 and the right end plate 1 are fixedly connected to the two sealing flanges by multiple screws. A wastewater inlet 11 is located at the center of the left end of the left end plate 5, and a clean water outlet 8 is located at the center of the right end of the right end plate 1. Mounting brackets 2 are welded to the bottom of both the left and right sides of the center of the pipeline treatment tank 3. The support plates 2 are all installed vertically downwards, and mounting base plates 4 are welded to the bottom of each support plate 2. The interior of the pipeline treatment tank 3, from left to right, consists of a filtration chamber 13, a biological treatment chamber 14, a chemical treatment chamber 15, and a clean water disinfection chamber 16. These chambers are separated by metal partitions, and each partition has a wastewater conveying port at its top. Wastewater from these chambers is conveyed to the next stage through these wastewater conveying ports. The bottom of the pipeline treatment tank 3 is equipped with multiple drain ports 10 at equal intervals. These drain ports 10 are connected to the interior of the filtration chamber 13, biological treatment chamber 14, chemical treatment chamber 15, and clean water disinfection chamber 16, respectively. Each drain port 10 is equipped with a shut-off valve at its bottom via a flange and screws. During the treatment process, impurities and sludge accumulate in each treatment chamber. By opening the shut-off valve at the bottom of the drain port 10, these wastes can be periodically discharged, ensuring the cleanliness of the treatment chamber and maintaining the treatment effect. The right end plate 1, the pipeline treatment tank 3, the left end plate 5, and the multiple metal partitions are all made of stainless steel. Stainless steel itself has a certain degree of corrosion resistance, which can resist the erosion of wastewater and the surrounding environment to a certain extent. The outer walls of the right end plate 1, the pipeline treatment tank 3, the left end plate 5, and multiple metal partitions are all sprayed with epoxy resin corrosion-resistant coating. The epoxy resin coating has good adhesion and can adhere tightly to the equipment surface. At the same time, it has excellent chemical resistance and can effectively resist the corrosion of various acid, alkali, and salt solutions in wastewater. It also has good wear resistance and can prevent surface damage caused by friction during daily operation, thereby further improving the overall corrosion resistance of the equipment and extending its service life.
[0024] like Figure 1 , Figure 2 and Figure 3As shown, the top of the pipeline treatment tank 3 is equidistantly equipped with multiple feed ports 6. These feed ports 6 are connected to the interior of the filtration chamber 13, biological treatment chamber 14, chemical treatment chamber 15, and clean water disinfection chamber 16, respectively. Each feed port 6 has a sealed end cap 7 at its top opening. When treating different types of wastewater or according to treatment needs, appropriate agents, microbial culture agents, etc., can be added to the corresponding treatment chamber by opening the sealed end cap 7 at the top of the feed port 6 to optimize the treatment process and improve wastewater treatment efficiency and quality. The wastewater inlet 11 is connected to the interior of the filtration chamber 13, and the clean water outlet 8 is connected to the interior of the clean water disinfection chamber 16. Multiple filter grilles 12 are installed on the upper side of the center of the filtration chamber 13, and all filter grilles 12 are located above and to the right of the wastewater inlet 11. Wastewater flows into the filtration chamber 13 through the wastewater inlet 11 on the left end plate 5. The multiple filter grilles 12 located above and to the right of the wastewater inlet 11 first intercept large particulate impurities and suspended solids in the wastewater, performing preliminary purification. The filtered wastewater flows into the biological treatment chamber 14 through the sewage conveying hole at the top of the metal partition, reducing the load on subsequent treatment units. Inside the biological treatment chamber 14, the organic pollutants in the wastewater are decomposed and transformed into harmless substances through the metabolism of microorganisms, further removing pollutants from the wastewater. The biologically treated wastewater then enters the chemical treatment chamber 15 through the sewage conveying hole. Appropriate chemical agents can be added to the chemical treatment chamber 15 through the feed port 6 at the top of the pipeline treatment tank 3, which reacts chemically with specific pollutants in the wastewater to remove substances that are difficult to remove through biological treatment, such as heavy metal ions and specific organic matter, further purifying the water quality. The chemically treated wastewater flows into the clean water disinfection chamber 16. During this process, disinfectants may be added or other disinfection methods may be used to disinfect the wastewater, killing bacteria, viruses and other microorganisms in the water, ensuring that the treated water meets the corresponding water quality standards, and finally discharged through the clean water outlet 8 of the right end plate 1.
[0025] like Figure 1 , Figure 4 and Figure 5As shown, an auxiliary purification device 9 is installed at the right end of the purified water outlet 8. The auxiliary purification device 9 includes an inlet water connection pipe 17, a cuboid treatment box 18, a sealing end plate 20, and a final water outlet 21. The inlet water connection pipe 17 is located at the center of the left end of the cuboid treatment box 18. Both the left end of the inlet water connection pipe 17 and the right end of the purified water outlet 8 are equipped with connecting flanges, and the two connecting flanges are fixedly connected by multiple screws. The inlet water connection pipe 17 communicates with the inside of the cuboid treatment box 18, and the right end of the cuboid treatment box 18 is open. A sealing end plate 20 is provided at the right end of the cuboid treatment box 18. A sealing gasket is also provided between the sealing end plate 20 and the cuboid treatment box 18. The sealing end plate 20 is fixedly connected to the cuboid treatment box 18 by multiple screws. A final water outlet 21 is provided at the center of the right end of the sealing end plate 20. The purified water after being treated by the pipeline treatment tank 3 flows out from the purified water outlet 8 and enters the auxiliary purification device 9 through the water inlet connector 17. The connecting flanges at both ends of the water inlet connector 17 are tightly fixedly connected by multiple screws to ensure the sealing of the connection. To prevent water leakage, purified water flows smoothly into the cuboid treatment box 18 through the inlet connector 17, providing a stable water flow for subsequent purification steps. The auxiliary purification device 9 also includes a lamp holder 19, an activated carbon filter 22, and ultraviolet lamps 23. The lamp holder 19 is fixed to the top of the cuboid treatment box 18, and multiple ultraviolet lamps 23 are equidistantly arranged at the bottom of the lamp holder 19. All the ultraviolet lamps 23 are inserted into the cuboid treatment box 18, and the multiple ultraviolet lamps 23 are arranged equidistantly from left to right inside the cuboid treatment box 18. An activated carbon filter 22 is also fixed to the left end of the end cap 20. The activated carbon filter 22 plays an important role after the purified water enters the cubic treatment box 18. Activated carbon has a rich microporous structure and a huge specific surface area. It can effectively adsorb residual small particulate impurities, dissolved organic matter, odor substances and some heavy metal ions in the water through physical adsorption. These pollutants are trapped in the pores of the activated carbon filter 22, thereby reducing the content of impurities in the water and improving the sensory properties of the water, such as making the water clearer, colorless and odorless.
[0026] like Figure 1 , Figure 4 and Figure 5As shown, after the sealing end plate 20 is fixed to the right end of the cuboid treatment box 18, the activated carbon filter 22 is inserted into the opening at the right end of the cuboid treatment box 18, and the final outlet 21 passes through the activated carbon filter 22 and communicates with the inside of the cuboid treatment box 18. The bottom ends of multiple ultraviolet lamps 23 are close to the inner wall of the bottom end of the cuboid treatment box 18, but do not contact the inner wall of the bottom end of the cuboid treatment box 18. The lamp holder 19 fixed at the top of the cuboid treatment box 18 provides support and power connection for the ultraviolet lamps 23. Multiple ultraviolet lamps 23 are arranged equidistantly from left to right at the bottom end of the lamp holder 19, and the bottom ends of the ultraviolet lamps 23 are close to but do not contact the inner wall of the bottom end of the cuboid treatment box 18. When the ultraviolet lamps 23 are turned on, they will emit ultraviolet rays of a specific wavelength. The ultraviolet rays can penetrate the cell walls and cell membranes of bacteria, viruses and other microorganisms, destroying their internal... The activated carbon filter 22 adsorbs the microorganisms in the water, rendering them inactive and unable to metabolize and reproduce normally, thus achieving sterilization and disinfection. As the water flows through the cubic treatment box 18, the ultraviolet light emitted by the ultraviolet lamp 23 provides comprehensive and uniform irradiation to the water, ensuring a significant reduction in the content of microorganisms in the water and further improving the sanitary quality of the water. The purified water, after being adsorbed by the activated carbon filter 22 and sterilized by the ultraviolet lamp 23, is discharged from the auxiliary purification device 9 through the final outlet 21. The final outlet 21 is connected to the inside of the cubic treatment box 18 through the activated carbon filter 22, ensuring that the purified water can flow out smoothly, while preventing particulate matter from the activated carbon filter 22 from flowing out with the water. After this series of treatments, the water quality is significantly improved, meeting stricter usage standards or discharge requirements.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
