[0023] 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.
[0024] This utility model provides, for example Figure 1-6 The emulsion wastewater treatment equipment shown includes a treatment tank 4 and a tank end cover 6 installed at the top of the treatment tank 4. The treatment tank 4 and the tank end cover 6 are fixedly connected by welding. Inside the treatment tank 4, from left to right, there are a filtration and conditioning chamber 10, a demulsification and oil removal chamber 11, an anaerobic treatment chamber 12, an aerobic treatment chamber 13, a sedimentation chamber 14, and a disinfection chamber 15. The filtration and conditioning chamber 10, the demulsification and oil removal chamber 11, the anaerobic treatment chamber 12, the aerobic treatment chamber 13, the sedimentation chamber 14, and the disinfection chamber 15 are separated from each other by partitions. The filtration and conditioning chamber 10 is equipped with multiple filter grids 16, which are arranged equidistantly from left to right. The diameter of the filter holes inside the multiple filter grids 16 is... From left to right, the wastewater inlet 9 is located on the upper side of the center of the left end of the treatment tank 4. The wastewater inlet 9 is connected to the interior of the filter regulating chamber 10. The emulsified wastewater enters the filter regulating chamber 10 from the wastewater inlet 9 at the left end of the treatment tank 4. Multiple filter grids 16 arranged equidistantly from left to right with decreasing filter hole diameters perform preliminary filtration of the wastewater. Large particles are first intercepted by the filter grid 16 with larger filter holes at the far left. As the wastewater flows to the right, smaller particles are blocked by the subsequent filter grids 16 with smaller filter holes. This initially removes suspended solids of different particle sizes from the wastewater, reducing the burden on subsequent treatments. At the same time, it regulates the water quality and quantity of the wastewater, making it more stable for entry into the next treatment stage.
[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple material windows 7 are equidistantly arranged at the top of the tank end cover 6. These material windows 7 are located directly above the filtration and conditioning chamber 10, the demulsification and oil removal chamber 11, the anaerobic treatment chamber 12, the aerobic treatment chamber 13, the sedimentation chamber 14, and the disinfection chamber 15, respectively. Each opening at the top of the material windows 7 is fitted with a sealing end cover 8. Multiple drain ports 1 are sequentially arranged at the front bottom of the treatment tank 4. These drain ports 1 are connected to the interiors of the filtration and conditioning chamber 10, the demulsification and oil removal chamber 11, the anaerobic treatment chamber 12, the aerobic treatment chamber 13, the sedimentation chamber 14, and the disinfection chamber 15, respectively. Multiple drain ports 1 are located at the front bottom of the filtration and conditioning chamber 10, between adjacent filter grids 16. Impurities and sludge generated during the treatment process are discharged through these drain ports 1 at the front bottom of the treatment tank 4. The multiple drain ports 1 at the bottom of the filtration and conditioning chamber 10, located between adjacent filter grids 16, can promptly discharge impurities generated during filtration, ensuring the smooth operation of each treatment process. During normal operation of the treatment chamber, the material window 7 on the top of the tank end cover 6 is used to add chemicals, and the sealing end cover 8 that is fitted to the top opening can prevent foreign matter from entering the treatment equipment, ensuring stable operation and treatment effect. Multiple grease discharge ports 3 are also provided on the upper side of the center of the front end of the treatment tank 4, and the multiple grease discharge ports 3 are located on the upper side of the center of the front of the demulsification and oil removal chamber 11. Demulsifiers can be added to the sewage inside the demulsification and oil removal chamber 11 through the material window 7. The demulsifiers can destroy the stability of the emulsion and cause the oil droplets to aggregate and float. The floating oil droplets can be discharged through the multiple grease discharge ports 3. The filtered and regulated wastewater enters the demulsification and oil removal chamber 11, and demulsifiers are added to the sewage inside the chamber through the material window 7 on the top of the tank end cover 6. The demulsifiers destroy the stability of the emulsion and cause the oil droplets to aggregate and float. The oil droplets rise to the water surface under the action of buoyancy and are discharged through the multiple grease discharge ports 3 on the upper side of the center of the front end of the treatment tank 4, realizing oil-water separation and reducing the oil content in the wastewater.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, frame plates are fixed to the lower side of the center of the rear inner wall of the demulsification and oil removal chamber 11, anaerobic treatment chamber 12, aerobic treatment chamber 13, and sedimentation chamber 14. Multiple transfer pumps 17 are fixed to these frame plates. Wastewater inside the demulsification and oil removal chamber 11, anaerobic treatment chamber 12, aerobic treatment chamber 13, and sedimentation chamber 14 is transported by the transfer pumps 17. A settling hopper 18 is installed on the lower side of the center inside the sedimentation chamber 14. The settling hopper 18 is located below the transfer pumps 17, and the opening area at the top of the settling hopper 18 is larger than that at the bottom. The treatment tank 4 has a clean water outlet 5 located on the lower right side of its center. The clean water outlet 5 is connected to the interior of the disinfection chamber 15. Wastewater after demulsification and oil removal is pumped by a transfer pump 17 on the frame plate to the anaerobic treatment chamber 12. In the anaerobic environment, anaerobic bacteria utilize the organic matter in the wastewater as a nutrient source for metabolic activities, decomposing complex organic matter into simple organic matter, carbon dioxide, and methane, effectively reducing the chemical oxygen demand (COD) of the wastewater and alleviating the pressure on subsequent treatment. The anaerobic treated wastewater is then... The wastewater enters the aerobic treatment chamber 13 via the transfer pump 17. Under aerobic conditions, aerobic bacteria use dissolved oxygen to further decompose the remaining organic matter in the wastewater into carbon dioxide and water, while converting ammonia nitrogen into nitrate nitrogen, etc. This process further removes pollutants from the wastewater and improves its biodegradability. The aerobically treated wastewater flows into the sedimentation chamber 14. A settling hopper 18 is set at the lower center of the sedimentation chamber 14. The unique structure of the settling hopper 18 (the top opening area is larger than the bottom opening area) facilitates the sedimentation process. Suspended particles and microbial flocs in the wastewater gradually sink to the bottom of the settling hopper 18 under the action of gravity, while the clear water flows upward, achieving solid-liquid separation and further purifying the wastewater. The settled wastewater is then transported to the disinfection chamber 15 by the transfer pump 17. In the disinfection chamber 15, the wastewater is disinfected by adding disinfectants to kill bacteria, viruses and other pathogens, ensuring that the water quality discharged from the clean water outlet 5 at the lower center of the right end of the treatment tank 4 meets the corresponding standards and can be safely discharged or reused.
[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, each of the multiple filter grilles 16 is equipped with a grille anti-clogging device 2 on its left end. The grille anti-clogging device 2 includes anti-clogging cleaning brush bristles 19, strip cleaning blocks 20, U-shaped lifting connecting rods 22, and lifting guide sleeves 25. The lifting guide sleeves 25 are inserted and fixed inside the tank end cover 6, and are located above the front side of the center of the filter adjustment chamber 10. The U-shaped lifting connecting rods 22 are inserted into the lifting guide sleeves 25, with the U-shaped opening of the U-shaped lifting connecting rods 22 facing downwards, and the front end of the U-shaped lifting connecting rods 22 is located on the front side of the outer wall of the front end of the treatment tank 4. The bottom of the rear end of the U-shaped lifting connecting rods 22 is welded with strip cleaning blocks 20, which are arranged longitudinally inside the filter adjustment chamber 10. Multiple anti-clogging cleaning brushes are evenly distributed on the outer wall of the right end of the strip cleaning blocks 20. The brush bristles 19 are tightly fitted to the filter grid 16 at the right end. The grid anti-clogging device 2 also includes a push-pull handle 21, an anti-rotation limiting plate 23, and an anti-rotation limiting hole 24. The anti-rotation limiting plate 23 is welded to the front end of the tank end cover 6. Multiple anti-rotation limiting holes 24 are provided inside the anti-rotation limiting plate 23. The anti-rotation limiting holes 24 are sleeved on the outside of the front end of the U-shaped lifting connecting rod 22. The push-pull handle 21 is connected to the bottom of the front end of the U-shaped lifting connecting rod 22. The push-pull handle 21 can drive the U-shaped lifting connecting rod 22 to move up and down. The front and rear ends of the U-shaped lifting connecting rod 22 can move up and down in the anti-rotation limiting hole 24 and the lifting guide sleeve 25, respectively. The lifting guide sleeve 25 and the anti-rotation limiting hole 24 are symmetrically matched to prevent the U-shaped lifting connecting rod 22 from rotating.
[0028] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the height of the U-shaped lifting connecting rod 22 is greater than the depth of the filter regulating chamber 10. When the filter screen 16 filters emulsified wastewater for a long time, impurities will continuously adhere to the screen, which may cause blockage. At this time, the anti-blockage cleaning work can be started by operating the push-pull handle 21. The push-pull handle 21 is connected to the bottom of the front end of the U-shaped lifting connecting rod 22. When the push-pull handle 21 is pulled or pushed, the U-shaped lifting connecting rod 22 will move up and down. The front and rear ends of the U-shaped lifting connecting rod 22 slide up and down in the anti-rotation limiting hole 24 and the lifting guide sleeve 25, respectively. The anti-rotation limiting plate 23 is welded to the front end of the tank end cover 6, and the anti-rotation limiting hole 24 inside it is sleeved on the outside of the front end of the U-shaped lifting connecting rod 22. The lifting guide sleeve 25 is inserted and fixed inside the tank end cover 6 and is located above the front side of the center of the filter regulating chamber 10. The two are symmetrically matched and can effectively prevent the U-shaped lifting connecting rod 22 from moving up and down. The movement generates rotation during operation, ensuring the stability and accuracy of the motion. Because a strip-shaped cleaning block 20 is welded to the bottom rear end of the U-shaped lifting connecting rod 22, and this strip-shaped cleaning block 20 is longitudinally arranged within the filter regulating chamber 10, with multiple anti-clogging cleaning bristles 19 evenly spaced and closely attached to the filter grid 16 on its right outer wall, as the U-shaped lifting connecting rod 22 moves up and down, the strip-shaped cleaning block 20 and the anti-clogging cleaning bristles 19 also reciprocate up and down along the filter grid 16. The anti-clogging cleaning bristles 19 can promptly brush off impurities adhering to the filter grid 16, keeping the filter grid 16 always transparent and maintaining good filtration performance. This ensures stable filtration of emulsified wastewater by the filter regulating chamber 10, thereby guaranteeing the efficient operation of the entire wastewater treatment equipment. Furthermore, the height of the U-shaped lifting connecting rod 22 is greater than the depth of the filter regulating chamber 10, allowing the cleaning work to cover the entire height range of the filter grid 16, achieving comprehensive and effective cleaning.
[0029] 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.
