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] Please see Figure 1-6 This utility model provides a technical solution: a coking wastewater treatment device based on MABR and MBR processes, comprising: a sewage pump 1, a water pipe 2 installed at one end of the sewage pump 1, a biological reactor 3 installed at the other end of the water pipe 2, an MABR component 4 installed on the inner wall of the biological reactor 3, an air supply component 5 installed on the surface of the biological reactor 3, a water pipe 6 installed on the other side of the biological reactor 3, an aerobic MBR tank 7 installed at the other end of the water pipe 6, an MBR component 8 installed inside the aerobic MBR tank 7, and a drainage component 9 installed on the other side of the aerobic MBR tank 7.
[0024] Specifically: When the device is started, wastewater is pumped into the biological reactor 3 through water pipe 2 by starting wastewater pump 1. The MABR module 4 installed inside the biological reactor 3 aerates the wastewater under the action of the MABR process. At the same time, the air supply component 5 installed on the surface of the biological reactor 3 supplies air to the MABR module 4 installed inside the biological reactor 3. The first intermediate water after treatment by the MABR module 4 enters the aerobic MBR tank 7 through water pipe 6. The aeration system inside the aerobic MBR tank 7 removes pollutants. Then, the second intermediate water is filtered by the MBR module 8 installed inside the aerobic MBR tank 7 to obtain clean water. Then, it is discharged through the drainage component 9 installed on the other side of the aerobic MBR tank 7. Thus, the device improves the denitrification effect and reduces the COD emission value by using a combination of MABR and MBR processes to form a biological treatment section, making the device more complete.
[0025] In one embodiment, a water tank 10 is installed at the other end of the sewage pump 1, an mounting plate 11 is installed on the top of the water tank 10, a filter plate 12 is installed at the bottom of the mounting plate 11, a rubber scraper 13 is installed on the surface of the filter plate 12, and the surface of the rubber scraper 13 is in contact with the inner wall of the water tank 10.
[0026] Specifically: When the device is first put into use, wastewater is added to one half of the space of the pool 10. It is then filtered through the filter plate 12 installed at the bottom of the mounting plate 11 and enters the other half of the space of the pool 10. Then, the sewage pump 1 is started to transport the pre-filtered wastewater to the biological reaction tank 3, making the device more complete.
[0027] In one embodiment, T-shaped grooves 14 are provided on both sides of the top of the water tank 10, and T-shaped blocks 15 are movably installed on the inner wall of the T-shaped grooves 14. The top of the T-shaped blocks 15 is installed at the bottom of one end of the mounting plate 11.
[0028] Specifically: The T-shaped block 15 installed at the bottom of the end of the mounting plate 11 is movably mounted on the inner wall of the T-shaped groove 14 opened on both sides of the top of the water tank 10. By pushing the mounting plate 11, the filter plate 12 moves on the inner wall of the water tank 10. The rubber scraper 13 installed on the surface of the filter plate 12 scrapes the sludge on both sides and bottom of the inner wall of the water tank 10, thereby cleaning the inner wall of the water tank 10 and making the device more perfect.
[0029] In one embodiment, bolts 16 are threaded into both ends of the mounting plate 11, and the surface threads of bolts 16 are embedded in the inner wall of the T-block 15.
[0030] Specifically: Bolts 16 are threaded at both ends of the mounting plate 11. The threads of the bolts 16 are embedded in the inner wall of the T-block 15. By unscrewing the bolts 16, the mounting plate 11 and the T-block 15 are released from fixation, and the filter plate 12 installed at the bottom of the mounting plate 11 can be removed from the inner wall of the water tank 10 for easy cleaning, making the device more complete.
[0031] In one embodiment, a drain outlet 1001 is provided at the bottom of the other side of the pool 10. An embedded block 18 is embedded in the inner wall of the drain outlet 1001. A sealing plate 17 is installed on one side of the embedded block 18. Bolts 19 are threadedly embedded at the four corners of the sealing plate 17. The surface threads of the bolts 19 are embedded in the interior of the pool 10. A sealing sheet 20 is installed on one side of the sealing plate 17.
[0032] Specifically: by unscrewing bolt 19, the sealing plate 17 is removed, and the embedded block 18 is taken out from the inner wall of the outlet 1001. By pushing the mounting plate 11, the sludge scraped off by the rubber scraper 13 will fall to the bottom of the inner wall of the pool 10 under the action of gravity. By continuing to push the mounting plate 11, the sludge is discharged through the outlet 1001, so that the sludge on both sides and the bottom of the inner wall of the pool 10 is treated, making the device more complete.
[0033] Working Principle: When the device is started, wastewater is pumped into the biological reactor 3 through water pipe 2 by starting wastewater pump 1. The MABR module 4 installed inside the biological reactor 3 aerates the wastewater under the MABR process. Simultaneously, air is supplied to the MABR module 4 by activating the air supply component 5 installed on the surface of the biological reactor 3. The first intermediate water after treatment by the MABR module 4 enters the aerobic MBR tank 7 through water pipe 6. Pollutants are removed by the aeration system inside the aerobic MBR tank 7. Then, the second intermediate water is filtered by the MBR module 8 installed inside the aerobic MBR tank 7 to obtain purified water, which is then discharged through the drainage component 9 installed on the other side of the aerobic MBR tank 7. Thus, the device uses a combined MABR and MBR process to form a biological treatment section, improving denitrification and reducing COD emissions, making the device more complete. When the device is started, wastewater is added to half of the space in the water tank 10, through the bottom of the mounting plate 11. The installed filter plate 12 performs preliminary filtration before the wastewater enters the other half of the water tank 10. Then, the sewage pump 1 is started to transport the pre-filtered wastewater into the biological reactor 3. After the device is in use, the T-shaped block 15 installed at the bottom of the end of the installation plate 11 is movable and installed on the inner wall of the T-shaped groove 14 opened on both sides of the top of the water tank 10. By pushing the installation plate 11, the filter plate 12 moves on the inner wall of the water tank 10. The rubber scraper 13 installed on the surface of the filter plate 12 removes the sewage from the sides and bottom of the inner wall of the water tank 10. The sludge is scraped off and flows to the bottom of the pool under gravity, and then discharged through the outlet 1001, so that the sludge on both sides and bottom of the inner wall of the pool 10 is treated. Bolts 16 are threaded at both ends of the mounting plate 11, and the threads of the bolts 16 are embedded in the inner wall of the T-block 15. By unscrewing the bolts 16, the mounting plate 11 and the T-block 15 are released from fixation, so that the filter plate 12 installed at the bottom of the mounting plate 11 can be removed from the inner wall of the pool 10 for easy cleaning, making the device more complete.
