Description

Technical Field

[0001] This utility model relates to the field of wastewater technology, specifically a novel wastewater denitrification and phosphorus removal device. Background Technology

[0002] With urban development and population growth, industrial and domestic wastewater are increasing, making wastewater treatment a critical issue that needs immediate attention. Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives. There are many ways to treat wastewater, among which using microorganisms to remove nitrogen and phosphorus from wastewater is a very environmentally friendly method. Microbial denitrification is the process of converting various nitrogen-containing compounds in wastewater into molecular nitrogen through nitrification and denitrification. Microbial phosphorus removal is based on the principle that microorganisms release phosphorus under anaerobic conditions and absorb excess phosphorus under aerobic conditions, ultimately causing phosphorus to accumulate in the remaining sludge, thereby removing phosphorus from wastewater.

[0003] Through long-term observation, we have found that existing urban sewage denitrification and phosphorus removal equipment often suffers from slow phosphorus removal efficiency and incomplete phosphorus removal during the process of using microorganisms for denitrification and phosphorus removal. Moreover, urban sewage contains a large number of impurities before denitrification and phosphorus removal, and these impurities need to be filtered out before denitrification and phosphorus removal to avoid affecting subsequent steps.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figures 1 to 7 This utility model provides a technical solution: a novel wastewater denitrification and phosphorus removal device, including an anaerobic tank 4, an inlet pipe 1 is provided on the inner side of the upper right part of the anaerobic tank 4, a first switch 2 is installed on the outer side of the inlet pipe 1, an outlet pipe 9 is provided on the inner side of the lower left part of the anaerobic tank 4, and a second switch 8 is installed on the outer side of the outlet pipe 9.

[0029] An oxygen pipe 5 is installed on the inner side of the middle of the right wall of the anaerobic chamber 4. An oxygen tank 6 is installed on the outer side of the right end of the oxygen pipe 5. A fixed frame 18 is fixedly connected to the outer side of the left end of the oxygen pipe 5. Fixed plates 17 are connected to the upper and lower sides of the fixed frame 18 through sealed bearings 16. A stirring shaft 13 is fixedly connected to the inner side of the fixed plate 17. An exhaust pump 29 is installed on the upper right side of the anaerobic chamber 4. A fixed rod 15 is fixedly connected to the middle of the front and rear inner walls of the anaerobic chamber 4. A second motor 11 is installed at the other end of the fixed rod 15. The downward output shaft of the second motor 11 is connected to the stirring shaft 13 through a coupling. An air inlet 19 is opened on the upper outer wall of the stirring shaft 13 inside the fixed frame 18. The mixing shaft 13 has a first air passage 25 inside. A mixing rod 12 is fixedly connected to the lower outer side of the mixing shaft 13. A second air passage 28 is opened inside the mixing rod 12. A second air outlet 27 is opened on the outer wall of the mixing rod 12. A first air outlet 26 is opened on the lower outer wall of the mixing shaft 13 at the connection of the mixing rod 12. The oxygen pipe 5 is connected to the first air passage 25 through the air inlet 19. The first air passage 25 is connected to the second air passage 28 through the first air outlet 26. The second air passage 28 is connected to the second air outlet 27. By setting the second air outlet 27 and the mixing rod 12, the microorganisms in the anaerobic chamber 4 can react quickly with oxygen to release phosphine and achieve the purpose of rapid phosphorus removal.

[0030] In use, after the filter screen 14 has finished filtering the sewage, open the valve above the oxygen tank 6 to allow oxygen to enter the anaerobic chamber 4 through the oxygen pipe 5. Then, start the second motor 11 to drive the stirring shaft 13 to rotate, which in turn drives the stirring rod 12 to rotate. At this time, the stirring shaft 13 drives the fixed plate 17 to rotate, while the fixed frame 18 remains stationary under the action of the sealed bearing 16 and the oxygen pipe 5. Under the action of the sealed bearing 16, oxygen enters the first air passage 25 from the oxygen pipe 5 through the air inlet 19, then enters the second air passage 28 from the first air passage 25 through the first air outlet 26, and is then sprayed out from the second air outlet 27, causing the oxygen to dissolve. In the wastewater, the contact area between oxygen and wastewater is increased, allowing microorganisms in the wastewater to fully contact oxygen and release phosphine, thus achieving phosphorus removal. At this time, oxygen enters the anaerobic tank 4 to create an oxygen-rich environment. After the microorganisms in the wastewater in the anaerobic tank 4 have reacted with oxygen, the exhaust pump 29 is turned on to extract the gas inside the anaerobic tank 4. At this time, the valve above the oxygen tank 6 is closed to stop the oxygen supply and create an anaerobic environment. After the microorganisms in the wastewater live under anaerobic conditions for a period of time, they will produce a large amount of nitrogen. The exhaust pump 29 is then turned on to discharge the nitrogen from the inside of the anaerobic tank 4, thus achieving denitrification.

A filter screen 14 is fixedly connected to the lower end of the connecting rope 23. A fixed shaft 24 is movably connected to the inner side of the left frame of the filter screen 14. Both ends of the fixed shaft 24 are fixedly connected to the anaerobic chamber 4. The lower part of the frame of the filter screen 14 cooperates with the fixing rod 15. By setting the filter screen 14, impurities in the sewage can be filtered in advance to avoid affecting the denitrification and phosphorus removal of the sewage, thereby improving the sewage purification efficiency.

[0034] When in use, turn on the first switch 2, and the sewage enters the anaerobic tank 4 from the inlet pipe 1 and reaches the filter screen 14. Start the first motor 3, and the output shaft of the first motor 3 drives the cam 20 to rotate, which in turn drives the fixed nail 22 to rotate upward, and then causes the movable wheel 21 to rotate around the fixed nail 22. At this time, the connecting rope 23 with the remaining length will drive the filter screen 14 to rotate counterclockwise around the fixed axis 24, so that the debris in the sewage enters the pull plate 10 with the inclined slope of the filter screen 14. Then pull the pull plate 10 to remove the debris.
