Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically an integrated dual-mode high-efficiency sewage treatment device. Background Technology

[0002] With increasingly stringent requirements for wastewater treatment and discharge, wastewater typically needs to be treated before being released. Water treatment is a process used to treat polluted water resources, thereby purifying wastewater and facilitating the removal of impurities from it.

[0003] The prior art provides a microbial wastewater treatment tank (publication number CN218146268U). This utility model includes a tank body, which includes a sedimentation zone, a purification zone, and an effluent zone. A water pump corresponding to the sedimentation zone and the purification zone is fixedly connected to the top of the tank body. A first motor is fixedly connected to the middle of the top of the purification zone. A stirring rod is fixedly connected to the output shaft of the first motor. A blower is fixedly connected to the top of the purification zone. An aeration pipe is fixedly connected to the end of the air outlet pipe away from the blower. A sludge pump corresponding to the purification zone and the effluent zone is fixedly connected to the top of the tank body. A second motor is fixedly connected to the middle of the top of the effluent zone. A second rotating shaft is fixedly connected to the output shaft of the second motor. A rotating cylinder is fixedly connected to the bottom of the second rotating shaft. A microfiltration membrane is fixedly connected to the inner wall of the rotating cylinder. Multiple through holes are opened on the side wall of the rotating cylinder. An effluent outlet is opened at the bottom of the effluent zone.

[0004] The aforementioned microbial wastewater treatment tank still has some problems in actual use. For example, when extracting wastewater from the sedimentation zone, the filter cover blocks and filters large particles of impurities in the wastewater. However, the large particles of impurities that are blocked are not cleaned, which will cause the large particles of impurities to clog the filter cover and affect the extraction of wastewater from the sedimentation zone. Therefore, we need to propose an integrated dual-mode high-efficiency wastewater treatment device. Utility Model Content

[0005] The purpose of this invention is to provide an integrated dual-mode high-efficiency sewage treatment device that can clean the filtered particulate impurities when extracting sewage from the sedimentation zone, thereby preventing excessive filtered particulate impurities from affecting the extraction of sewage from the sedimentation zone, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] An integrated dual-mode high-efficiency sewage treatment device includes a housing 1. The housing 1 has a sedimentation zone 2 inside. A mesh frame 11 is fixedly connected to the inner wall of the sedimentation zone 2. An installation plate 13 is installed inside the mesh frame 11. A filter box 18 is fixedly installed on the top of the installation plate 13. A flexible hose 17 is connected to the bottom of the filter box 18. A connecting pipe 23 is connected to the top of the filter box 18. A second drive motor 19 is fixedly installed on the top of the filter box 18. A connecting rod 20 is fixedly connected to the output shaft of the second drive motor 19 through a coupling. A scraper 21 is fixedly installed at the lower end of the connecting rod 20. A filter screen 22 is fixedly installed inside the filter box 18. The scraper 21 is in contact with the filter screen 22.

[0027] It should be noted that by setting the floating block 14 as a floating foam cement board, the floating foam cement board has the ability to float because its density is less than that of water and it contains a large number of air bubbles. The filter box 18 can float on the surface of the sewage through the floating block 14, so that the position of the connecting pipe 23 can be adjusted according to the water level, so that the connecting pipe 23 is always located close to the water surface, which can prevent the sediment from getting too close to the sediment inside the sedimentation zone.

[0028] In addition, in order to facilitate the cleaning of particulate impurities filtered out by the filter screen 22, a movable door 33 is provided on the filter box 18. By opening the movable door 33, the particulate impurities filtered out by the filter screen 22 can be cleaned.

[0029] In an optional embodiment: a water pump 15 is fixedly installed on the side of the housing 1. The inlet and outlet of the water pump 15 are both connected to a first extraction pipe 16. The first extraction pipe 16 at the inlet of the water pump 15 is connected to the sedimentation zone 2, and the first extraction pipe 16 at the inlet of the water pump 15 is connected to a hose 17.

[0030] In an optional embodiment: the interior of the housing 1 is provided with a purification zone 3 and a filtration zone 4, and the first extraction pipe 16 of the water pump 15 outlet is located in the purification zone 3.

[0031] In an optional embodiment: two sets of positioning rods 12 are fixedly installed on the top of the grid frame 11, the mounting plate 13 is slidably installed on the positioning rods 12, the bottom of the mounting plate 13 is fixedly installed with a floating block 14, the connecting pipe 23 is fixedly installed in the mounting plate 13 and the floating block 14, and the inner wall of the purification zone 3 is fixedly installed with a support block 24 for blocking the floating block 14.

[0032] It should be noted that the positioning rod 12 can be used to position the mounting plate 13 and the floating block 14, so that the floating block 14 can move stably when it moves due to the rise and fall of the sewage water level.

[0033] In addition, the support block 24 serves to block the mounting plate 13 and the floating block 14, preventing the connecting pipe 23 from being inserted into the sediment due to low water level.

[0034] In an optional embodiment: a first drive motor 5 is fixedly installed on the top of the housing 1, and the output shaft of the first drive motor 5 is fixedly connected to a stirring rod 6 via a coupling. The stirring rod 6 is located in the sedimentation zone 2.

[0035] In an optional embodiment: the bottom of the box 1 is fixedly connected to a discharge rack 7 that communicates with the sedimentation zone 2, the bottom of the discharge rack 7 is connected to a discharge pipe 8, and a discharge valve 9 is provided on the discharge pipe 8.

[0036] It should be noted that the discharge pipe 8 and the discharge valve 9 work together to discharge the sediment.

[0037] In an optional embodiment: a blower 26 is fixedly installed on the side of the housing 1, and the air outlet of the blower 26 is connected to an aeration pipe 27, which is located in the purification zone 3.

[0038] In an optional embodiment: a sealing plate 25 is fixedly installed on the inner wall of the purification zone 3, an exhaust pipe 28 is connected to the sealing plate 25, and a pressure valve 29 is provided on the exhaust pipe 28.

[0039] It should be noted that if the pressure inside purification zone 3 becomes too high, the pressure valve 29 will automatically open to release air, thus preventing excessive pressure within purification zone 3.

[0040] In an optional embodiment: a sludge pump 30 is fixedly installed on the top of the sealing plate 25. The inlet and outlet of the sludge pump 30 are both connected to a second extraction pipe 31. The second extraction pipe 31 at the inlet of the sludge pump 30 is located in the purification zone 3, and the second extraction pipe 31 at the outlet of the sludge pump 30 is located in the filtration zone 4.

[0041] In an optional embodiment: a support mesh 32 is fixedly installed on the inner wall of the filtration zone 4, and a microfiltration membrane 10 is disposed on the top of the support mesh 32.

[0042] In practical use, wastewater is transported to sedimentation zone 2. The precipitant is poured into sedimentation zone 2, and the first drive motor 5 is started. The output shaft of the first drive motor 5 rotates, which drives the stirring rod 6 to rotate. When the stirring rod 6 rotates, the precipitant and wastewater can be stirred, thereby fully mixing the precipitant and wastewater. The precipitate can accumulate in sedimentation zone 2.

[0043] The water pump 15 is started. The water pump 15 draws sewage through the first extraction pipe 16, hose 17, filter box 18 and connecting pipe 23. The screen frame 11 can block and filter large particles of impurities in the sewage, preventing large particles of impurities from being drawn into the filter box 18. The drawn sewage falls into the filter box 18 through the connecting pipe 23 and is filtered by the filter screen 22. The filtered sewage is then transported to the sedimentation zone 2 through the hose 17 and the first extraction pipe 16. While the filter screen 22 is filtering the sewage, the second drive motor 19 is started. The output shaft of the second drive motor 19 rotates and drives the connecting rod 20 to rotate. When the connecting rod 20 rotates, it drives the scraper 21 to rotate. When the scraper 21 rotates, it can scrape and clean the particulate impurities filtered on the top of the filter screen 22, preventing the particulate impurities from clogging the filter screen 22.

[0044] When wastewater is transported to purification zone 3, activated sludge is placed inside. Blower 26 is started, and blower 26 delivers air through aeration pipe 27 to purification zone 3 for continuous aeration. The oxygen in the air delivered to purification zone 3 comes into contact with the microorganisms in the activated sludge, providing them with sufficient oxygen. After treatment, sludge pump 30 is started. Sludge pump 30 pumps the wastewater mixed with activated sludge from purification zone 3 into filtration zone 4 through second extraction pipe 31. The wastewater mixed with activated sludge is filtered through microfiltration membrane 10. After being filtered through microfiltration membrane 10, the clean water falls to the bottom of filtration zone 4 and is discharged. Activated sludge is filtered and collected on microfiltration membrane 10. When a large amount of activated sludge has been collected, it can be cleaned and put back into purification zone 3 for reuse.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
