Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment equipment technology, specifically a wastewater treatment mixing tank based on microbial treatment. Background Technology
[0002] Wastewater treatment refers to the process of treating wastewater using physical, chemical, and biological methods to meet discharge or reuse standards. Microorganisms can decompose and transform pollutants such as organic matter, nitrogen, and phosphorus in wastewater, thus purifying the wastewater and resulting in better effluent quality that meets higher discharge standards.
[0003] Existing microbial treatment methods require injecting a substrate containing a large number of microorganisms into the wastewater during the treatment process. During injection, a stirring device is needed to mix the substrate to ensure it can be easily and evenly spread, thereby increasing the purification effect. In existing injection schemes, the injection and mixing operations are usually separated, which is relatively unchanging. Therefore, a wastewater treatment mixing tank based on microbial treatment is proposed to solve the above-mentioned problems. Utility Model Content

[0025] 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.
[0026] In the embodiments, by Figure 1-4 The present invention discloses a wastewater treatment mixing tank based on microbial treatment. The present invention includes a tank body 1. A release shaft 2 is rotatably connected inside the tank body 1, with both ends extending to the two sides of the tank body 1 respectively. A three-way valve 3 is rotatably connected to one end of the release shaft 2. The inlet end of the three-way valve 3 is connected to a microbial feed pipe 4, and the other outlet end of the three-way valve 3 is connected to a circulation pipe 5. A circulation tank 6 connected to the circulation pipe 5 is provided outside the tank body 1. The other end of the microbial feed pipe 4 is connected to a substrate source circulation pump 7. A rotation drive 8 for driving the microbial feed pipe 4 to rotate is fixedly installed on the outside of the tank body 1.
[0027] Furthermore, the three-way valve 3 is a solenoid valve, and a hydraulic sensor is installed at the end of the three-way valve 3 that is connected to the circulating pump 7.
[0028] Specifically, the three-way valve is controlled by a controller, which can control its inlet end to connect to either of the other two outlet ends, and can control the three-way valve to switch to a fully closed state. When the three-way valve is fully closed, the circulation pump is activated by a hydraulic sensor.
[0029] Furthermore, the release shaft 2 has a single row of equally spaced release holes located inside the pool body 1, and a disturbance plate is fixedly installed on the outside of the release shaft 2, which is opposite to the position of the release holes.
[0030] When the release shaft 2 rotates, it can drive the disturbance plate to rotate, thereby causing the external sewage to flow, which facilitates the mixing of microorganisms. Under normal circumstances, the substrate inside the release shaft 2 can be discharged through the release hole, thus facilitating the purification of the water.
[0031] Furthermore, the end of the release shaft 2 is sealed, and the outside of the release shaft 2 is provided with multiple elastic sealing members 9 that correspond one-to-one with the release holes and block them.
[0032] Furthermore, the elastic sealing member 9 includes a release frame 91 fixed to the outside of the release shaft 2, an elastic member 92 fixedly installed on the inner side of the release frame 91, and a rubber sealing block 93 for blocking the release hole is fixedly connected to the other end of the elastic member 92.
[0033] By setting the elastic sealing element 9, when there is no pressure inside the release shaft 2, the release hole can be sealed by the elastic element 92 in conjunction with the rubber sealing block 93 to prevent sewage from entering. When there is hydraulic pressure inside the release shaft 2, the rubber sealing block 93 can be directly pushed open to form a matrix injection, and under the maintenance of hydraulic pressure, sewage can be prevented from entering.
[0034] Furthermore, the rotation drive component 8 includes a drive motor 81 fixed to the outside of the pool body 1. A transmission sprocket 82 is fixedly provided on the outer side of the output shaft of the drive motor 81 and the outer side of the release shaft 2. The two transmission sprockets 82 are connected by a chain 83.
[0035] When the drive component 8 needs to drive the release shaft 2 to rotate, it can directly drive the release shaft 2 to rotate through the transmission sprocket 82 and chain 83.
[0036] Working principle:
[0037] In use, the rotation drive 8 is activated first to drive the release shaft 2 to start rotating. Then, the three-way valve 3 can be controlled so that the circulation pump 7 can pump the substrate containing microorganisms into the release shaft 2 through the microorganism feed pipe 4 and the three-way valve 3. Then, the substrate containing microorganisms can be released through the release shaft 2.
[0038] After feeding is completed, the three-way valve 3 switches to connect the microbial feed pipe 4 with the circulation pipe 5, so that the substrate can flush the inner wall of the pipe to prevent sewage backflow from causing microbial contamination. After flushing is completed, the three-way valve 3 can be switched to a fully closed state to standby, waiting for the next feeding. The flushing substrate in the circulation tank 6 is treated according to whether it is contaminated and the degree of contamination.
