Description

Technical Field

[0001] The present invention relates to the technical field of hydrolysis acidification reaction, and particularly relates to a high-efficiency hydrolysis acidification reactor for sewage treatment. Background Art

[0002] The hydrolysis (acidification) treatment method is the preliminary stage of anaerobic treatment. Some scholars have found that according to the different growth conditions of methanogens and hydrolytic acid-producing bacteria, the anaerobic treatment is controlled under the condition of containing a large number of hydrolytic bacteria and acidifying bacteria. The process of using hydrolytic bacteria and acidifying bacteria to hydrolyze insoluble organic matter in water into soluble organic matter and convert macromolecular substances that are difficult to biodegradable into small molecular substances that are easy to biodegradable, thereby improving the biodegradability of wastewater and providing a good water quality environment for subsequent biochemical treatment.

[0003] Common high-efficiency hydrolysis acidification reactors for sewage treatment only include the function of hydrolysis acidification reaction, which can convert the organic matter that is difficult to biodegradable in sewage into organic matter that is easy to biodegradable, but lack the functions of quickly cleaning mud and controlling temperature. It is impossible to ensure that the laid mud can be quickly cleaned up and the hydrolysis acidification reaction can be maintained at the optimal temperature. It is easy to occur that the laid mud adheres to the bottom of the tank and is difficult to clean after encountering water, and it is also easy to occur that the temperature in the tank body cannot be controlled at the optimal state of microbial metabolism, affecting the mud cleaning effect and the hydrolysis acidification reaction efficiency.

[0004] Therefore, aiming at the lack of functions of quickly cleaning mud and controlling temperature in the above-mentioned high-efficiency hydrolysis acidification reactor for sewage treatment, a high-efficiency hydrolysis acidification reactor for sewage treatment can be designed. Open the sludge discharge door, and then start the electric telescopic rod. The electric telescopic rod drives the mud pushing plate that is initially in contact with the partition plate to move to the right. While the mud pushing plate moves to the right, it pushes the mud laid at the bottom inside the reaction tank body to move to the right until the mud is discharged outside the reaction tank body, ensuring that the mud can be quickly cleaned up. The temperature of the sewage in the reaction tank is detected by a water temperature sensor of model PT100, and the detected data is transmitted to the PLC controller. The PLC controller compares the detected data with the pre-set data. When the temperature is too high or too low, the PLC controller controls the electric heating plate to start and controls the output power of the electric heating plate, so as to control the temperature of the sewage in the reaction tank body and ensure that the hydrolysis acidification reaction is maintained at the optimal temperature. Summary of the Invention

To solve the problems of the common high - efficiency hydrolysis - acidification reactor for sewage treatment, which only includes the function of hydrolysis - acidification reaction, can convert the organic matter that is difficult to biodegrade in sewage into the organic matter that is easy to biodegrade, but lacks the functions of quickly cleaning the mud and controlling the temperature, and cannot ensure that the laid mud can be quickly cleaned up and the hydrolysis - acidification reaction is maintained at the optimal temperature. It is easy for the laid mud to stick to the bottom of the tank and be difficult to clean after encountering water, and it is also easy for the temperature in the tank body to be unable to be controlled at the optimal state of microbial metabolism, affecting the mud cleaning effect and the efficiency of the hydrolysis - acidification reaction.

[0018] 1. Open the sludge discharge door, and then start the electric telescopic rod. The electric telescopic rod drives the sludge pushing plate initially fitted with the partition plate to move to the right. While the sludge pushing plate moves to the right, it pushes the soil laid at the bottom end inside the reaction tank body to move to the right until the soil is discharged outside the reaction tank body, ensuring that the soil can be quickly cleaned up. This is to solve the problem that the common high-efficiency hydrolysis acidification reactor for sewage treatment only has the function of hydrolysis acidification reaction, which can convert the organic matter difficult to be biodegradable in sewage into the organic matter easy to be biodegradable, but lacks the function of quickly cleaning the soil, and it is impossible to ensure that the laid soil can be quickly cleaned up. It is easy to occur that the laid soil adheres to the bottom of the tank and is difficult to clean after being wetted by water, affecting the soil cleaning effect.

[0019] 2. The temperature of the sewage in the reaction tank is detected by a water temperature sensor of type PT100, and the detected data is transmitted to the PLC controller. The PLC controller compares the detected data with the pre-set data. When the temperature is too high or too low, the PLC controller controls the electric heating plate to start and controls the output power of the electric heating plate, so as to control the temperature of the sewage in the reaction tank and ensure that the hydrolysis acidification reaction is maintained at the optimal temperature. This is to solve the problem that the common high-efficiency hydrolysis acidification reactor for sewage treatment only contains the function of hydrolysis acidification reaction, which can convert the hardly biodegradable organic matter in sewage into easily biodegradable organic matter, but lacks the function of controlling temperature, cannot ensure that the hydrolysis acidification reaction is maintained at the optimal temperature, and is prone to the problem that the temperature in the tank cannot be controlled at the optimal state of microbial metabolism, affecting the hydrolysis acidification reaction efficiency.

Open the sludge discharge door 7, and then start the electric telescopic rod 5. The electric telescopic rod 5 drives the sludge pushing plate 6 that is initially in contact with the partition plate 2 to move to the right. While the sludge pushing plate 6 moves to the right, it pushes the soil laid at the bottom end inside the reaction tank body 1 to move to the right until the soil is discharged outside the reaction tank body 1, ensuring that the soil can be quickly cleaned up.

The PLC controller 11 compares the detected data with the pre-set data. When the temperature is too high or too low, the PLC controller 11 controls the electric heating plate 8 to start and controls the output power of the electric heating plate 8, so as to control the temperature of the sewage in the reaction tank body 1 and ensure that the hydrolysis acidification reaction is maintained at the optimal temperature. To solve the problem of the common high-efficiency hydrolysis acidification reactor for sewage treatment, which only includes the function of hydrolysis acidification reaction and can convert the organic matter that is difficult to biodegrade in sewage into the organic matter that is easy to biodegrade, but lacks the functions of quickly cleaning soil and controlling temperature, and cannot ensure that the laid soil can be quickly cleaned up and the hydrolysis acidification reaction is maintained at the optimal temperature. It is easy to occur that the laid soil adheres to the bottom of the tank and is difficult to clean after contacting water, and it is easy to occur that the temperature in the tank cannot be controlled at the optimal state of microbial metabolism, affecting the soil cleaning effect and the hydrolysis acidification reaction efficiency.

[0029] Please refer to Figures 2-6, in this embodiment, a sealing top plate 10 is provided at the top of the reaction tank body 1. A PLC controller 11 is provided in the middle of the front side of the top of the sealing top plate 10. The PLC controller 11 is electrically connected to the electric heating plate 8 and the water temperature sensor 9. A stepped plate 12 is provided at the top of the support plate 3. A first filter frame 13 is arranged at equal intervals on the top of the stepped plate 12. A first filter screen 14 is arranged inside the first filter frame 13. The left end of the front side of the reaction tank body 1 is movably connected with a sealing door 15 through a hinge. An external water inlet pipe 17 is arranged at the middle position corresponding to the stepped plate 12 at the left top end of the reaction tank body 1. An internal water inlet pipe 16 is arranged at the middle position corresponding to the stepped plate 12 under the right side of the partition plate 2. A drain pipe 20 is arranged at the middle position of the right top end of the reaction tank body 1. When it is necessary to clean the laid soil, the sludge discharge door 7 is opened, and then the electric telescopic rod 5 is started. The electric telescopic rod 5 drives the mud pushing plate 6 initially attached to the partition plate 2 to move to the right. While the mud pushing plate 6 moves to the right, it pushes the soil laid at the bottom end inside the reaction tank body 1 to move to the right until the soil is discharged outside the reaction tank body 1, ensuring that the soil can be quickly cleaned, realizing the function of quickly cleaning the soil, and preventing the problem that the laid soil adheres to the bottom of the tank and is difficult to clean after contacting water, which affects the soil cleaning effect.

[0030] Please refer to Figures 1-6, in this embodiment, a second filter frame 18 is provided in the middle on the right side of the partition plate 2 corresponding to the positions of the water temperature sensor 9 and the inner water inlet pipe 16. A second filter screen 19 is provided inside the second filter frame 18. A water delivery pipe 21 is provided in the middle on the right side of the bottom of the sealing top plate 10 corresponding to the position of the second filter screen 19. The top end of the water delivery pipe 21 penetrates through the sealing top plate 10 and is located on its top. A water distribution pipe 22 is provided at the bottom end of the water delivery pipe 21. A number of water distribution pipes 23 are symmetrically arranged at equal intervals on the front and rear sides of the whole body of the water distribution pipe 22. A nozzle 24 is provided in the middle below the whole body of the water distribution pipe 23. The water delivery pipe 21, the water distribution pipe 22 and the water distribution pipes 23 are integrally formed by welding. Four support legs 25 are provided at the four corners of the bottom of the reaction tank body 1. Self-locking universal wheels 26 are provided at the bottom ends of the four support legs 25. Open the sludge discharge door 7, lay the soil at the bottom end inside the reaction tank body 1, and add hydrolytic acidification bacteria to the soil. Then close the sludge discharge door 7. Then connect the connecting pipe of the external sewage conveying device to the outer water inlet pipe 17 and the water delivery pipe 21. Then, through the external sewage conveying device, add sewage into the reaction tank body 1 through the outer water inlet pipe 17. After the sewage enters the reaction tank body 1, it flows towards the partition plate 2 via the stepped plate 12. While the sewage is flowing on the stepped plate 12, large-sized impurities in it are filtered by the three-layer first filter screen 14. After the sewage is filtered, it continues to flow to the right side inside the reaction tank body 1 through the inner water inlet pipe 16. At the same time, the external sewage conveying device conveys the sewage into the water distribution pipe 22 through the water delivery pipe 21, and then conveys the sewage into several water distribution pipes 23 respectively through the water distribution pipe 22, and finally sprays out through the nozzles 24. The sewage sprayed out through the nozzles 24 drives the sewage inside the reaction tank body 1 to flow, so that the sludge and the hydrolytic acidification bacteria are in full contact, thereby completing the hydrolytic acidification reaction. The clear water after the sewage reaction is discharged from the drain pipe 20. While the hydrolytic acidification reaction is carried out, the temperature of the sewage in the reaction tank body 1 is detected by the water temperature sensor 9 of model PT100, and the detected data is transmitted to the PLC controller 11. The PLC controller 11 compares the detected data with the pre-set data. When the temperature is too high or too low, the PLC controller 11 controls the electric heating plate 8 to start and controls the output power of the electric heating plate 8, so as to control the temperature of the sewage in the reaction tank body 1, ensure that the hydrolytic acidification reaction is maintained at the optimal temperature, realize the function of controlling the temperature, and prevent the problem that the temperature in the tank cannot be controlled at the optimal state of microbial metabolism, affecting the efficiency of the hydrolytic acidification reaction.

[0031] When working, open the sludge discharge door 7, lay the soil at the bottom inside the reaction tank body 1, add hydrolytic acidification bacteria to the soil, then close the sludge discharge door 7, and then connect the connecting pipe of the external sewage conveying equipment to the external water inlet pipe 17 and the water conveying pipe 21. Then, through the external sewage conveying equipment, add sewage into the reaction tank body 1 through the external water inlet pipe 17. After the sewage enters the reaction tank body 1, it flows towards the partition plate 2 via the step plate 12. While the sewage flows on the step plate 12, the large-size sundries in it are filtered through the three-layer first filter screen 14. After the sewage is filtered, it continues to flow to the right side inside the reaction tank body 1 through the internal water inlet pipe 16. At the same time, the external sewage conveying equipment conveys the sewage into the internal water distribution pipe 22 through the water conveying pipe 21, and then conveys the sewage into several water distribution pipes 23 through the water distribution pipe 22, and finally sprays out through the nozzles 24. The sewage sprayed out through the nozzles 24 drives the sewage inside the reaction tank body 1 to flow, so that the sludge and the hydrolytic acidification bacteria are fully contacted, thus completing the hydrolytic acidification reaction. The clear water after the sewage reaction is discharged from the drain pipe 20. While the hydrolytic acidification reaction is carried out, the temperature of the sewage in the reaction tank body 1 is detected by the water temperature sensor 9 of model PT100, and the detected data is transmitted to the PLC controller 11. The PLC controller 11 compares the detected data with the pre-set data. When the temperature is too high or too low, the PLC controller 11 controls the electric heating plate 8 to start and controls the output power of the electric heating plate 8, so as to control the temperature of the sewage in the reaction tank body 1 and ensure that the hydrolytic acidification reaction is maintained at the optimal temperature. When it is necessary to clean the laid soil, open the sludge discharge door 7, and then start the electric telescopic rod 5. The electric telescopic rod 5 drives the mud pushing plate 6 initially fitted with the partition plate 2 to move to the right. While the mud pushing plate 6 moves to the right, it pushes the soil laid at the bottom inside the reaction tank body 1 to move to the right until the soil is discharged outside the reaction tank body 1, ensuring that the soil can be quickly cleaned up, realizing the functions of quickly cleaning the soil and controlling the temperature.

[0032] Through the above steps, the sludge discharge door 7 is opened, and then the electric telescopic rod 5 is started. The electric telescopic rod 5 drives the mud pushing plate 6 that is initially in contact with the partition plate 2 to move to the right. While the mud pushing plate 6 moves to the right, it pushes the mud laid at the bottom inside the reaction tank body 1 to move to the right until the mud is discharged outside the reaction tank body 1, ensuring that the mud can be quickly cleaned up. The temperature of the sewage in the reaction tank body 1 is detected by a water temperature sensor 9 of model PT100, and the detected data is transmitted to the PLC controller 11. The PLC controller 11 compares the detected data with the pre-set data. When the temperature is too high or too low, the PLC controller 11 controls the electric heating plate 8 to start and controls the output power of the electric heating plate 8, thereby controlling the temperature of the sewage in the reaction tank body 1 and ensuring that the hydrolysis acidification reaction remains at the optimal temperature. This is to solve the problem of a common high-efficiency hydrolysis acidification reactor for sewage treatment, which only has the function of hydrolysis acidification reaction and can convert the organic matter that is difficult to biodegradable in sewage into easily biodegradable organic matter, but lacks the functions of quickly cleaning mud and controlling temperature, and cannot ensure that the laid mud can be quickly cleaned up and the hydrolysis acidification reaction remains at the optimal temperature. It is easy to occur that the laid mud adheres to the bottom of the tank and is difficult to clean after contacting water, and it is also easy to occur that the temperature in the tank cannot be controlled at the optimal state of microbial metabolism, affecting the mud cleaning effect and the hydrolysis acidification reaction efficiency.
