Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a sewage treatment device for ecological environment governance. Background Art

[0002] With the development of society, the concept of environmental protection has taken root in people's hearts. Sewage treatment is usually included in the promotion services of environmental protection technologies. Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, and catering, and is also increasingly entering the daily lives of ordinary people. Among them, in the work of ecological environment governance, sewage needs to be pretreated before being discharged into the external water source to filter out impurities in the sewage to prevent them from entering the natural world and causing pollution. Existing methods for removing impurities from domestic sewage mostly involve setting a trash cover at the drainage outlet or sewage manhole, or setting a trash net at the connection position between the drainage passage and the water body. Through the trash cover or trash net, impurities and garbage in domestic sewage can be intercepted outside the water flow to prevent them from being discharged into the water body. Then, the staff can regularly go to the trash net to clean up the intercepted impurities uniformly, thus completing the impurity removal operation of sewage. However, domestic sewage converges from all corners of the city and contains a large amount of garbage. If these garbage are intercepted by the trash cover at the drainage outlet or sewage manhole, they will accumulate on the road surface or inside buildings, affecting the urban environment and the living comfort of residents. Moreover, the trash net can only physically filter larger garbage. The water body usually contains a large amount of inorganic substances, etc. Directly discharging it into rivers and lakes is likely to cause eutrophication of the water body, thus affecting the ecological environment and unable to treat and recycle sewage.

[0003] Therefore, the present invention provides a sewage treatment device for ecological environment governance. Summary of the Invention

[0015] Advantages of the present invention:

[0016] 1. Install a treatment tank in the sewage tank, set up a filtration chamber in the treatment tank, slidably install a water storage tank on the treatment tank, and install a sliding structure in the sewage tank. The sliding structure can drive the water storage tank to slide up and down, so that the filtration and purification process of the water body can be adjusted according to the content of impurities in the water body, and a suitable purification process can be selected according to actual needs, improving the efficiency of sewage treatment on the basis of ensuring the sewage treatment effect, and the water in the sewage tank can be sent into the filtration chamber for filtration treatment, so as to treat a large amount of algae, duckweed, etc. in the sewage tank.

[0017] 2. A filter shell is rotatably fitted in the filtration chamber, a water pumping structure is installed in the treatment tank, and a blocking structure is installed in the filtration chamber. The sewage can be filtered by the filter shell, and the filter shell can be rotated to treat the garbage filtered by the filter shell.

Oxygen can also be generated by the aquatic water purification plants for the aerobic microorganisms to work. And the jet structure injecting air can quickly make the aerobic microorganisms evenly cover the entire sewage tank, thus improving the sewage purification efficiency. At the same time, the relatively high content of oxygen, organic matter and inorganic matter will cause more algae and the like to grow naturally in the sewage tank, and the algae can be treated by sliding down the water storage tank.

[0019] 4. A buffer structure and an auxiliary filtration structure are installed in the auxiliary purification tank. The sewage can be assisted in purification and filtration by the auxiliary purification tank. For sewage with higher purification requirements, the sewage treatment effect can be further improved.

Detailed implementation mode

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0032] Please refer to Figures 1 to 10 , the present invention provides a technical solution: a sewage treatment device for ecological environment treatment, including a sewage tank 1, a plurality of auxiliary purification tanks 2 are fixed under the sewage tank 1, a collection box 4 is slidably matched under the sewage tank 1, a treatment tank 9 is installed in the sewage tank 1, a filtering cavity 13 is opened in the treatment tank 9, a water storage tank 10 is slidably matched on the treatment tank 9, a sliding structure is installed in the sewage tank 1, the sliding structure corresponds to the water storage tank 10, a jet structure is installed in the sewage tank 1, the jet structure corresponds to the sliding structure, a filtering shell 15 is rotatably matched in the filtering cavity 13, a pumping structure is installed in the treatment tank 9, a blocking structure is installed in the filtering cavity 13, the blocking structure corresponds to the filtering shell 15 and the pumping structure, the treatment tank 9 corresponds to the filtering cavity 13, a buffering structure and an auxiliary filtering structure are installed in the auxiliary purification tank 2, and the buffering structure corresponds to the auxiliary filtering structure.

[0033] In this embodiment, a support frame 5 is fixed on the sewage tank 1, a sewage discharge pipe 6 is fixed on the support frame 5, and the end of the sewage discharge pipe 6 is located above the water storage tank 10. The sliding structure includes a sliding frame 25 slidably matched in the sewage tank 1, and a sliding groove 24 is opened in the sewage tank 1, and the sliding groove 24 corresponds to the sliding frame 25.

[0034] Specifically, the sewage discharge pipe 6 can directly discharge sewage into the water storage tank 10 until the water level of the sewage in the water storage tank 10 rises above the water inlet 11. At this time, the sewage can flow into the filtering cavity 13 through the water inlet 11 for filtration. The water storage tank 10 can be driven up and down by the sliding frame 25. When the water storage tank 10 slides to the lower side of the water level and the upper side of the water inlet 11, the water in the sewage tank 1 can flow into the water storage tank 10 and then into the filtering cavity 13 for filtration, so that algae and the like in the sewage tank 1 can be treated; when the sliding frame 25 drives the water storage tank 10 to slide to the lower side of the water inlet 11, the sewage flowing into the water storage tank 10 can directly flow into the sewage tank 1, so as to purify the sewage; the device can select the position of the water storage tank 10 according to whether there are solid impurities in the sewage and whether there are many algae and the like in the sewage tank 1, so that the device is more flexible to use and can filter the sewage repeatedly to ensure the sewage treatment effect.

[0035] A plurality of telescopic rods 26 are fixed on the sewage tank 1. The end of the telescopic rod 26 is fixedly connected to the sliding frame 25. The telescopic rod 26 includes a first rod body 32 and a second rod body 33. A chute 35 is formed in the first rod body 32. A piston 34 is slidably fitted in the chute 35. The piston 34 is fixedly connected to the second rod body 33.

[0036] Specifically, air can be inflated or extracted from the chute 35. When air is inflated into the chute 35, the air pressure in the chute 35 can be increased, thereby pushing the piston 34 to move downward, causing the piston 34 to drive the second rod body 33 to move downward, thereby driving the sliding frame 25 to move downward, and causing the sliding frame 25 to drive the water storage tank 10 to move downward, so as to control the water in the water storage tank 10 to flow into the water inlet 11 or the sewage tank 1, thereby selecting a suitable purification process; when air is extracted from the chute 35, the air pressure in the chute 35 is reduced, so that the piston 34 moves upward, the piston 34 drives the second rod body 33 to move upward, thereby driving the sliding frame 25 to move upward, and causing the sliding frame 25 to drive the water storage tank 10 to move upward, so that the water level in the water storage tank 10 is higher than the water inlet 11, so that the water in the water storage tank 10 can flow into the filtration chamber 13 for filtration, so as to treat the garbage in the sewage and facilitate the collection and cleaning of the garbage, without manually cleaning the filtered garbage.

[0037] The jet structure includes a first air pipe 27 fixed in the sewage tank 1. A plurality of second air pipes 28 are fixed on the first air pipe 27. A plurality of air outlets 36 are formed in the second air pipe 28. One-way valves are installed in the air outlets 36. A third air pipe 29 is fixed on the telescopic rod 26. The third air pipe 29 is communicated with the chute 35. A plurality of fourth air pipes 30 are installed between the third air pipe 29 and the first air pipe 27. A first valve 45 is installed on the fourth air pipe 30. A fourth valve is installed on the first air pipe 27. An air inlet pipe 31 is fixed on one side of the sewage tank 1. The air inlet pipe 31 is communicated with the first air pipe 27.

[0038] Specifically, when jetting air into the sewage tank 1, the fourth valve can be opened and the first valve 45 can be closed. At this time, air is introduced into the first air pipe 27 through the air inlet pipe 31, so that oxygen is ejected from the air outlet 36, so as to supply oxygen to the aerobic microorganisms in the sewage tank 1, ensure the survival rate of the aerobic microorganisms, and at the same time enable the aerobic microorganisms to purify the water body. The water in the sewage tank 1 will flow relatively under the action of the gas, so that the aerobic microorganisms in the sewage tank 1 can be more evenly distributed in the sewage tank 1. If a purification agent is added to the sewage tank 1, it can also be quickly mixed with the water body under the action of the gas, improving the purification effect on the sewage; when the fourth valve is closed and the first valve 45 is opened, air is inflated or extracted through the air inlet pipe 31, so as to inflate or extract air from the chute 35, thereby driving the sliding frame 25 to slide up and down, and driving the water storage tank 10 to slide up and down, so as to adjust the water purification process.

[0039] The top of the filtering chamber 13 is provided with a water inlet 11, and the bottom of the filtering chamber 13 is provided with a blanking port 37. The blanking port 37 is located above the collection box 4. A motor 12 is fixed in the processing box 9, and the output end of the motor 12 is fixedly connected to the filtering shell 15. The filtering shell 15 is of a hemispherical shell structure, and a plurality of through holes 14 are provided on the peripheral side of the filtering shell 15. The pumping structure includes a plurality of water pumps 20 fixed in the processing box 9. The water inlet end of the water pump 20 is fixed with a water inlet pipe 21, and the water outlet end of the water pump 20 is fixed with a water outlet pipe 22. The water outlet pipe 22 is communicated with the sewage pool 1. A plurality of communication ports 23 are provided on the peripheral side of the filtering chamber 13, and the communication ports 23 correspond to the water inlet pipes 21.

[0040] Specifically, when sewage flows into the water inlet 11, at this time, after the sewage is filtered by the filtering shell 15, it flows between the filtering shell 15 and the plug 16. Then, the water pump 20 is started, and the water pump 20 can be used to pump water, so as to send the water pump 20 into the sewage pool 1; the motor 12 is started, so that the motor 12 drives the filtering shell 15 to rotate, and the filtering shell 15 can be turned over. Thus, the impurities filtered in the filtering shell 15 will naturally fall. At this time, the impurities filtered by the filtering shell 15 will naturally fall into the collection box 4, so that there is no need to manually clean the filtered impurities, reducing the working intensity. At this time, the falling water will impact the filtering shell 15, thereby flushing the filtering shell 15 and washing all the impurities adhered to the filtering shell 15, preventing the filtering shell 15 from being blocked.

[0041] The blocking structure includes a plug 16 slidably fitted in the filtering chamber 13. An upper limit plate 17 and a lower limit plate 18 are fixed in the filtering chamber 13. The upper limit plate 17 and the lower limit plate 18 are respectively located on the upper and lower sides of the communication port 23. The plug 16 is located between the upper limit plate 17 and the lower limit plate 18. A spring 19 is fixed between the plug 16 and the lower limit plate 18, and the plug 16 is in contact with the filtering shell 15.

[0042] Specifically, when the filtering shell 15 is turned over, at this time, the filtering shell 15 no longer limits the plug 16. At this time, the spring 19 rebounds and pushes the plug 16 to move upward until the plug 16 contacts the upper limit plate 17, so that the plug 16 blocks the communication port 23; when the filtering shell 15 rotates upward, at this time, the filtering shell 15 presses the plug 16 downward, so that the plug 16 slides downward and the spring 19 is compressed. At this time, the plug 16 seals the lower side of the filtering shell 15, and the communication port 23 is opened. Thus, the sewage filtered by the filtering shell 15 will be retained above the plug 16, which is convenient for the water pump 20 to pump water, so as to send the sewage to the sewage pool 1 for purification.

[0043] A first drain pipe 7 is fixed on one side of the sewage tank 1, a second valve 46 is installed on the first drain pipe 7, the first drain pipe 7 is communicated with the sewage tank 1, a second drain pipe 8 is fixed on one side of the auxiliary purification tank 2, and the second drain pipe 8 is communicated with the auxiliary purification tank 2.

[0044] Specifically, for sewage with a relatively low purification requirement, the sewage can be directly discharged through the first drain pipe 7. For sewage with a relatively high purification requirement, it can be further purified by the auxiliary purification tank 2 and then discharged through the second drain pipe 8. The water level in the sewage tank 1 can also be adjusted through the first drain pipe 7. When the water level in the sewage tank 1 is relatively low, the second valve 46 on the first drain pipe 7 is closed at this time, and the sewage tank 1 can store water.

[0045] The sewage tank 1 is fixedly connected to the auxiliary purification tank 2. An electric slide rail 3 is installed between the two auxiliary purification tanks 2. The electric slide rail 3 corresponds to the collection box 4. A partition 38 is fixed in the sewage tank 1. The partition 38 is located above the air jet structure, and aquatic purification plants are planted on the partition 38.

[0046] Specifically, the sewage can be further purified by the auxiliary purification tank 2, and the auxiliary purification tank 2 can also be used to raise the sewage tank 1, so that a sliding space for the collection box 4 is generated below the sewage tank 1. Thus, the collection box 4 can be slid out through the electric slide rail 3, facilitating the cleaning of the impurities filtered in the collection box 4.

[0047] A water outlet 39 is provided between the sewage tank 1 and the auxiliary purification tank 2. A third valve is installed in the water outlet 39. The buffer structure includes a first filter plate 40 and a second filter plate 41 fixed in the auxiliary purification tank 2. A plurality of filter holes 42 are provided in both the first filter plate 40 and the second filter plate 41. The filter holes 42 in the first filter plate 40 are staggered with the filter holes 42 in the second filter plate 41, and both the first filter plate 40 and the second filter plate 41 are located above the auxiliary filtration structure. The auxiliary filtration structure includes a packing filtration structure 44. A third filter plate 43 is fixed in the auxiliary purification tank 2, and the packing filtration structure 44 is fixed above the third filter plate 43. The packing filtration structure 44 includes an activated carbon layer, a soil layer, a gravel layer, etc.

[0048] Specifically, when auxiliary purification of the auxiliary purification tank 2 is required, the third valve is opened at this time, so that the sewage in the sewage tank 1 can flow from the water outlet 39 to the auxiliary purification tank 2. At this time, it can be filtered through the filter holes 42 of the first filter plate 40 and the second filter plate 41. The staggered structure can achieve better filtration and prevent the sewage from directly impacting the packing filtration structure 44, thus achieving a certain buffering effect. Then, further filtration is carried out through the activated carbon layer, the soil layer and the gravel layer. Microbial treatment can be carried out through the microorganisms in the soil layer and the gravel layer, thereby ensuring the sewage purification effect.

[0049] Workflow: The sewage can be directly discharged into the water storage tank 10 through the sewage pipe 6. When there are no solid impurities in the sewage, close the fourth valve at this time, open the first valve 45, and inflate through the air inlet pipe 31, then the chute 35 can be inflated. The air pressure in the chute 35 increases, thereby pushing the piston 34 to move downward, causing the piston 34 to drive the second rod 33 to move downward, and then driving the sliding frame 25 to move downward, so that the sliding frame 25 drives the water storage tank 10 to move downward, and the water in the water storage tank 10 can be controlled to flow into the sewage pool 1, and then the sewage can be directly purified by the microorganisms and aquatic purification plants in the sewage pool 1. When the purification requirement is low, after the purification is completed, open the second valve 46, and the sewage can be directly discharged from the first drain pipe 7.

[0050] When the sewage contains solid impurities, air is pumped through the intake pipe 31 at this time, and the air in the chute 35 can be pumped out. The air pressure in the chute 35 decreases, so that the piston 34 moves upward, causing the piston 34 to drive the second rod 33 upward, thereby driving the sliding frame 25 upward, making the sliding frame 25 drive the water storage tank 10 upward, so that the water level in the water storage tank 10 is higher than the water inlet 11, so that the water in the water storage tank 10 can flow into the filtration chamber 13 for filtration. After the sewage flows into the water inlet 11, the sewage flows through the filtration of the filter shell 15 and then flows between the filter shell 15 and the plug 16. Then the water pump 20 is started, and the water can be pumped through the water pump 20, so that the water pump 20 is sent into the sewage pool 1. Then the motor 12 is started, so that the motor 12 drives the filter shell 15 to rotate, and the filter shell 15 can be turned over. The filter shell 15 no longer limits the plug 16. At this time, the spring 19 rebounds and pushes the plug 16 upward until the plug 16 contacts the upper limit plate 17, so that the plug 16 blocks the communication port 23. The impurities filtered out by the filter shell 15 naturally fall. At this time, the impurities filtered out by the filter shell 15 will naturally fall into the collection box 4. After the falling is completed, the motor 12 is started, so that the motor 12 drives the filter shell 15 to reset. At this time, the filter shell 15 presses the plug 16 downward, so that the plug 16 slides downward and the spring 19 is compressed. At this time, the plug 16 seals the lower side of the filter shell 15, and the communication port 23 is opened. Therefore, the sewage filtered by the filter shell 15 will be retained above the plug 16, which is convenient for the water pump 20 to pump water, so that the sewage can be sent to the sewage pool 1 for purification. The fourth valve is opened and the first valve 45 is closed. At this time, air is introduced into the first air pipe 27 through the intake pipe 31, so that oxygen is ejected from the air outlet 36, and the aerobic microorganisms in the sewage pool 1 can be supplied with oxygen to ensure the survival rate of the aerobic microorganisms. At the same time, the aerobic microorganisms can purify the water body, and the water in the sewage pool 1 will flow relatively under the action of the gas, so that the aerobic microorganisms in the sewage pool 1 can be more evenly distributed in the sewage pool 1. If a purification agent is added to the sewage pool 1, it can also be quickly mixed with the water body under the action of the gas to improve the purification effect of the sewage; then the third valve is opened, so that the sewage in the sewage pool 1 can flow from the water outlet 39 to the auxiliary purification tank 2. At this time, it can be filtered through the filter holes 42 of the first filter plate 40 and the second filter plate 41. The staggered structure can filter well and prevent the sewage from directly impacting the filler filtration structure 44, so that a certain buffering effect can be achieved. Then it is further filtered through the activated carbon layer, the soil layer and the gravel layer, and then the further purified sewage can be discharged from the second drain pipe 8; when there are more impurities in the collection box 4, the electric slide rail 3 is started at this time, so that the electric slide rail 3 drives the collection box 4 to slide outwards, so that the collection box 4 can be slid out, and the impurities in the collection box 4 can be cleaned. Since the plug 16 can block the filter shell 15 to prevent water from flowing out at this time, the impurities in the collection box 4 can be cleaned while filtering and purifying.

[0051] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution.
