Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and particularly to a device for recycling and treating sewage in an ecological sanitation system. Background Art

[0002] Currently, as an emerging sewage treatment technology, the ecological sanitation system utilizes ecological principles to achieve the natural purification and recycling of sewage by constructing an artificial ecological system. Among them, the plant-microbe symbiotic system is the core component of the ecological sanitation system. Through the root action of plants and the degradation of the microbial community attached to the roots, it can effectively remove pollutants such as organic matter, nitrogen, and phosphorus in sewage, while realizing the recycling of water resources.

[0003] In the prior art, the Chinese patent application with the publication number CN115521023A discloses a new type of ecological sewage treatment equipment and its treatment process. The process includes the preliminarily treated sewage entering the treatment box body, and the sewage will be absorbed by the green plant planting layer laid on the surface of the uppermost partition board. The sewage absorbed by the green plant planting layer will infiltrate downward after being purified by the green plant planting layer. The infiltrated sewage will successively pass through the surface soil alignment layer, the microbial filling layer, and the bottom filter soil layer. The sewage can be purified through the green plant planting layer, the surface soil alignment layer, the microbial filling layer, and the bottom filter soil layer; the purified sewage will fall on the surface of the diversion bottom plate and flow along the inclined diversion bottom plate to the water outlet at the end of the partition board, and be discharged outward through the water outlet penetrating the end of the partition board; then, through the above multi-layer structure, it is easy to cause soil erosion, making the purified sewage mixed with soil and water impurities, resulting in poor sewage purification effect. Summary of the Invention

[0004] In order to reduce the impact of soil erosion on sewage purification and maintain the sewage purification effect, this application provides a device for recycling and treating sewage in an ecological sanitation system.

[0005] A device for recycling and treating sewage in an ecological sanitation system provided by this application adopts the following technical solutions:

[0006] A device for recycling and treating sewage in an ecological sanitation system includes:

[0007] A water storage chamber, which forms a treatment cavity for storing sewage;

[0008] A treatment chamber, which is arranged on one side of the water storage chamber, is communicated with the water storage chamber, and a valve is arranged at the communication part;

[0009] A partition layer is provided in the treatment chamber, and a treatment area is formed, and plants are cultivated. The roots of the plants extend to the treatment area between the water storage chamber and the treatment chamber, and a microbial community for treating sewage is attached to the roots of the plants;

[0010] A clean water tank is provided on one side of the treatment chamber;

[0011] A connecting pipe has one end communicated with the side of the treatment chamber away from the water storage chamber and the other end communicated with the clean water tank, and a control valve is provided.

[0012] By adopting the above technical solutions, an ecological sanitation system is formed by the cooperation of the microbial community and plants. When treating sewage, sewage is supplied into the treatment chamber from the water storage chamber, and then the sewage is allowed to stand for a period of time during treatment. The microbial community on the roots of the plants in the partition layer decomposes or aggregates the impurities in the sewage. The treated sewage enters the clean water tank through the connecting pipe and the control valve; the device collects sewage through the water storage chamber, and the plants in the treatment chamber and the microbial community attached to their roots jointly act on the sewage to realize purification processes such as the degradation of organic matter and the removal of nitrogen and phosphorus; the setting of the partition layer makes the treatment area form a relatively closed environment, which is beneficial to the growth and reproduction of the microbial community. At the same time, the roots of the plants provide an attachment surface for the microorganisms, enhancing the biological treatment effect; the clean water tank, as the container for finally collecting the purified water, ensures that the treated water quality meets the standard for recycling; the device uses a plant-microbial symbiotic system to treat sewage without adding chemical agents, which is environmentally friendly; the selection and cultivation of plants not only beautify the environment, but also provide additional ecological services for the system through physiological activities such as photosynthesis.

[0013] Through the setting of the partition layer, the use of soil for fixing the roots of plants is reduced, the further pollution of sewage by the soil is reduced, the purified sewage can be kept clean, and the loss of water and soil can be reduced, so that the plants can maintain a good growth trend.

[0014] Optionally, a filter screen is provided on the water storage chamber, and the filter screen is located on the side of the water storage chamber close to the partition layer for filtering large impurities.

[0015] By adopting the above technical solutions, the filter screen, as the first line of defense for sewage to enter the treatment system, can effectively intercept and remove large particle impurities in the sewage, such as suspended solids, garbage, hair, etc.; through pretreatment, the burden on subsequent treatment units (such as the plant-microbial symbiotic system in the treatment chamber) can be reduced, and the treatment efficiency and stability of the whole system can be improved.

[0016] The existence of large impurities may cause physical damage to the roots of the plants and the microbial community in the treatment chamber, and even block the pipeline, affecting the normal operation of the system; the setting of the filter screen effectively avoids this problem and protects the integrity and functionality of the treatment system.

[0017] Removing large impurities can reduce the wear and corrosion of internal components of the system (such as pipes, valves, etc.), thereby extending the service life of the entire system; at the same time, clean sewage also helps to maintain the healthy growth of plants and microorganisms, further improving the stability and durability of the system.

[0018] By removing large impurities, it is possible to reduce the attachment of large impurities to the roots of plants, reduce the impact on plant growth, and at the same time reduce the damage to the microbial community, creating a better growth environment.

[0019] Optionally, a biofilm is provided on one side of the treatment chamber close to the partition layer, and the biofilm is used for further treating the sewage.

[0020] By adopting the above technical solution, the biofilm, as an efficient biological treatment method in sewage treatment, can significantly improve the sewage treatment capacity. The biofilm is composed of an ecosystem highly dense with aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa, and algae, etc. These microorganisms attach, grow, and reproduce on the biofilm, forming a stable biological community. When the sewage flows through the biofilm, the microorganisms can absorb and decompose the organic matter in the water, purifying the sewage. This biological treatment method not only improves the treatment efficiency but also enhances the stability and reliability of the system.

[0021] The biofilm method further treats the sewage, which can further remove pollutants such as organic matter, nitrogen, and phosphorus in the sewage, improving the effluent quality. The microorganisms on the biofilm, through metabolic processes, convert the organic matter into inorganic substances such as carbon dioxide and water, and at the same time achieve the removal of nutrients such as nitrogen and phosphorus. This treatment method makes the effluent quality clearer and more transparent, meeting the standards for recycling.

[0022] The setting of the biofilm also helps to extend the service life of the sewage treatment system. On the one hand, the biofilm can protect the plant roots and microbial community in the treatment chamber from the impact and damage of large particulate impurities; on the other hand, the biofilm itself has a certain self-renewal and repair ability, which can maintain its treatment efficiency and stability. This self-repair mechanism reduces the maintenance and repair costs of the system and extends the service life of the system.

[0023] Compared with traditional sewage treatment methods, the biofilm method has the advantages of energy conservation and consumption reduction. The microorganisms on the biofilm can utilize the organic matter in the sewage as energy for growth and reproduction during the process of degrading organic matter, without additional energy consumption. At the same time, the biofilm method has a high treatment efficiency, reducing the treatment time and treatment cost.

[0024] The biofilm forms a partition from the filter screen, reducing the flow of the formed sediment, keeping the treated water clean, and reducing the mutual influence between the partition layers.

[0025] Optionally, a multi-layer grid is arranged in the partition layer, and the multi-layer grid is used to restrict the plant roots.

[0026] By adopting the above technical solution, the arrangement of the multi-layer grid can reasonably divide and restrict the growth space of plant roots. By adjusting the spacing and height between the grids, an appropriate root growth environment can be created according to the growth characteristics and requirements of plants. This restriction not only helps the healthy development of plant roots, but also can stratify the plant roots and reduce the mutual interference between the roots.

[0027] The root restriction technology can affect the absorption of water and nutrients by plants, thereby regulating the growth rate and metabolic activities of plants. In the process of sewage treatment, plant roots play an important role in biological purification by absorbing, transforming and releasing pollutants. The arrangement of the multi-layer grid makes the plant roots more concentrated in a limited growth space, enhancing the contact area and reaction time between the roots and the sewage, thus improving the sewage treatment efficiency.

[0028] The multi-layer grid not only restricts the growth space of plant roots, but also plays a role in supporting and fixing plants. In a sewage treatment system, the growth state of plants directly affects the stability and treatment effect of the system. Through the support of the grid, plants can better adapt to different growth conditions, and can reduce the swing of the roots during the water flow, reducing the detachment of the microbial community, so that the sewage decomposition effect can be maintained.

[0029] Reasonable root restriction is helpful for the healthy growth of plants. The arrangement of the multi-layer grid can avoid excessive entanglement and competition of roots, reduce the nutrient competition and growth pressure between plants. At the same time, the grid can also provide a certain support and fixing effect for plants, preventing plant lodging and root damage caused by natural factors such as wind and rain.

[0030] Optionally, the grid is made of an elastic material, and an elastic part with a wavy shape is formed on the side away from the bottom wall of the partition layer, and a bent part is formed on the side close to the bottom wall of the partition layer, and the rigidity of the bent part is greater than that of the elastic part;

[0031] A driving component is arranged on the treatment chamber, the driving component is connected to the bent part, drives the bent part to bend, and can be separated from the bent part, and the bent part drives the elastic part to shake by its own elastic force.

[0032] By adopting the above technical solution, after a period of sewage treatment, aerobic heterotrophic bacteria, such as Alcaligenes, Bacillus, Flavobacterium, Pseudomonas, Zoogloea, etc., aggregate small sewage particles to form precipitates. The driving component drives the bending part to move and makes the elastic part shake, causing the precipitates attached to the plant roots and the grid to fall, reducing the interference to the microbial community. At the same time, it can reduce the influence of the intricate roots on the fall of the precipitates, keeping the roots clean.

[0033] The grid is made of elastic material, which gives it certain flexibility and restorability, enabling it to adapt to different deformation requirements; the use of elastic material can also reduce stress concentration during the force-bearing process of the grid, improve the durability of the overall structure, and reduce excessive restraint on plant roots.

[0034] The wavy design increases the surface area of the grid, provides more opportunities for contact with plant roots, and helps to better restrict root growth; the wavy structure also has a certain elastic buffering effect, which can reduce the impact force of the roots on the grid; the bending part is more rigid than the elastic part, enabling the grid to maintain a certain shape stability when subjected to external forces; the connection design between the bending part and the driving component enables the grid to achieve active movement through external drive, increasing the flexibility of the structure; the driving component can drive the bending part to bend, thereby achieving active control of the grid; the detachable design of the driving component and the bending part enables the connection to be released when driving is not required, reducing energy consumption and wear.

[0035] Optionally, the driving component includes:

[0036] A rotating shaft, rotatably connected to the interlayer, with one end extending out of the interlayer;

[0037] An impeller, connected to the end of the rotating shaft outside the interlayer. The water outlet end of the communicating pipe corresponds to the blades of the impeller and pushes the impeller to rotate;

[0038] A lever, arranged on the rotating shaft, contacting one side of the bending part, and capable of elastically deforming and separating from the bending part as it rotates.

[0039] By adopting the above technical solution, the impeller is connected to the end of the rotating shaft outside the interlayer. When discharging the treated water into the clean water tank, the water flow impacts the impeller, causing the impeller to rotate. The impeller rotates and drives the rotating shaft to rotate, making full use of the water flow energy and achieving effective utilization of energy.

[0040] The lever is arranged on the rotating shaft and contacts one side of the bent part; as the rotating shaft rotates, the lever can push the bent part to bend and separate from the bent part at a specific position, so that the bent part drives the elastic part to shake by its own elastic force; the contact design between the lever and the bent part ensures that the driving force can be accurately and effectively transmitted to the bent part, while avoiding structural damage caused by over-driving.

[0041] Through the above settings, the shaking of the grid is carried out during drainage and has periodicity, so that the sediment quickly precipitates towards the lower end of the partition layer. Moreover, the setting of the lever slightly disturbs the water at the lower end inside the partition layer, causing the sediment to flow horizontally at the lower end of the partition layer, facilitating entry into the slag discharge hole.

[0042] Optionally, a partition board is arranged on the partition layer, a slag inlet hole is opened on the partition board, the partition board divides one side of the treatment area close to the bottom wall of the treatment chamber into a sedimentation area, and a slag discharge hole is opened at the lower end of the partition layer;

[0043] A flow guide plate is arranged on the partition layer, and the flow guide plate corresponds to the slag discharge hole for discharging through the slag discharge hole;

[0044] A first sealing plate and a second sealing plate are slidably connected to the partition layer. The first sealing plate corresponds to the bottom wall of the partition layer, and a first blocking hole is opened on the first sealing plate. The first blocking hole corresponds to the slag discharge hole, and as the first sealing plate slides, the first blocking hole communicates with the slag discharge hole; the second sealing plate corresponds to the partition board, and a second blocking hole is opened on the second sealing plate. The second blocking hole corresponds to the slag inlet hole, and as the second sealing plate slides, the second blocking hole can communicate with or close the slag inlet hole, and the slag inlet hole and the slag discharge hole are alternately closed.

[0045] By adopting the above technical solution, the sediment converges above the partition board. When sediment discharge is required, slide the second sealing plate to make the slag inlet hole communicate with the second blocking hole, and the sediment enters between the partition board and the first sealing plate through the slag inlet hole. Then slide the second sealing plate to block the slag inlet hole on the partition board, and then slide the first sealing plate to make the slag discharge hole communicate with the first blocking hole. The sediment falls on the flow guide plate through the slag discharge hole and is diverted by the flow guide plate away from the partition layer; this helps to reduce the diffusion of sediment in the treatment area and improve the treatment efficiency. The settings of the slag inlet hole and the slag discharge hole enable the sediment to enter and exit the treatment area orderly, avoiding the accumulation and blockage of sediment; by sliding the first sealing plate and the second sealing plate, the timing of sediment entry and discharge can be precisely controlled to meet different treatment requirements.

[0046] Optionally, a resetting member is arranged on the treatment chamber, and the first sealing plate and the second sealing plate both correspond to the resetting member, and the resetting member is used to drive the first sealing plate and the second sealing plate to slide.

[0047] By adopting the above technical solution, through the arrangement of the reset member, the first plugging hole and the slag discharge hole are kept misaligned, and the second plugging hole and the slag inlet hole are kept misaligned, which can reduce the excessive discharge of sewage.

[0048] Optionally, a pushing assembly is arranged on the rotating shaft, and the pushing assembly includes:

[0049] A reciprocating screw rod coaxially connected to the rotating shaft;

[0050] A slider that slides on the partition layer and is threadedly connected to the reciprocating screw rod, can abut against the first sealing plate and the second sealing plate, and drives the first sealing plate and the second sealing plate to slide and squeeze the reset member.

[0051] By adopting the above technical solution, during the rotation of the rotating shaft, the reciprocating screw rod is driven to rotate, the reciprocating screw rod drives the slider to slide, and the slider pushes the first sealing plate and the second sealing plate to slide, so that the slag inlet hole and the slag discharge hole are alternately opened to complete the discharge of the sediment; through the above arrangement, the setting of additional power is reduced, and it helps to reduce the waiting time and energy consumption during the treatment process, improving the overall treatment efficiency; keeping the partition layer clean.

[0052] Optionally, the pushing assembly further includes:

[0053] A slip ring that slides on the rotating shaft along the length direction of the rotating shaft and rotates with the rotating shaft, and the slider can push the first sealing plate to slide through the slip ring;

[0054] A cam is arranged on the slip ring and abuts against one side of the first sealing plate close to the slip ring.

[0055] By adopting the above technical solution, during the sliding of the slider, the slip ring slides with the slider, the slider drives the cam to rotate, and the cam drives the first sealing plate to slide back and forth at intervals, so that the sediment shakes between the first sealing plate and the second sealing plate, facilitating the discharge of the sediment.

[0056] In summary, the present application includes at least one of the following beneficial technical effects:

[0057] 1. The arrangement of the partition layer makes the treatment area form a relatively closed environment, which is conducive to the growth and reproduction of the microbial community. At the same time, the plant roots provide an attachment surface for the microorganisms, enhancing the biological treatment effect; through the arrangement of the partition layer, the use of soil for fixing the plant roots is reduced, the further pollution of the sewage by the soil is reduced, the purified sewage can be kept clean, and the soil and water loss can be reduced, enabling the plants to maintain a good growth trend;

[0058] 2. The shaking of the grid is carried out during drainage and is periodic, enabling the sediment to quickly settle towards the lower end of the interlayer. Moreover, the arrangement of the push rods causes slight disturbance to the water at the lower end inside the interlayer, making the sediment flow horizontally at the lower end of the interlayer, facilitating its entry into the slag discharge holes.

[0059] 3. It helps to reduce the spread of sediment in the treatment area and improve the treatment efficiency. The settings of the feed slag hole and the slag discharge hole enable the sediment to enter and exit the treatment area orderly, avoiding the accumulation and blockage of sediment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0066] The following is a Figures 1 to 5 further detailed description of the present application.

[0067] This embodiment discloses an ecological sanitation system sewage recycling and treatment device.

[0068] Referring to Figure 1 and Figure 2, An ecological sanitation system sewage recycling and treatment device, comprising: a water storage chamber 100 for storing sewage, a treatment chamber 200 disposed on one side of the water storage chamber 100 for sewage treatment, a plurality of compartments 300 disposed in the treatment chamber 200 for storing microbial communities, a water purification tank 400 disposed on one side of the treatment chamber 200 for recovering the treated sewage, and a connecting pipe 500 disposed between the treatment chamber 200 and the water purification tank 400. When sewage treatment is carried out, first, sewage is added from the water storage chamber 100 into the treatment chamber 200. The sewage is decomposed and aggregated by the microbial community in the treatment chamber 200, making the sewage clean, and then discharged into the water purification tank 400 through the connecting pipe 500.

[0069] The water storage chamber 100 is communicated with the treatment chamber 200 through a bent connecting pipe 110. The height of the lowest part of the water storage chamber 100 is higher than the height of the treatment chamber 200. The connecting position of the connecting pipe 110 and the treatment chamber 200 is located on the side close to the bottom of the treatment chamber 200, and a valve is provided on the connecting pipe 110. The connecting pipe 500 is connected to the side of the treatment chamber 200 close to the bottom and is far from the connecting pipe 110. A control valve is provided on the connecting pipe 500. The end of the connecting pipe 500 far from the treatment chamber 200 is bent and is located above the water purification tank 400. The water purification tank 400 is located on one side of the treatment chamber 200. A sedimentation tank 920 for collecting sediment impurities is provided directly below the treatment chamber 200. The compartment 300 is provided with a discharge port for discharging sediment, and the discharge port corresponds to the sedimentation tank 920.

[0070] Refer to Figure 3 , A treatment area is formed in the compartment 300, and one end protrudes from the treatment chamber 200. A bearing platform for carrying plants is formed at the end protruding from the treatment chamber 200. Plants are planted on the bearing platform, and the roots of the plants extend into the treatment area of the compartment 300. Microbial communities are attached to the roots of the plants. A filter screen 610 for filtering larger impurities is provided on the side of the compartment 300 close to the connecting pipe 110. A biological membrane 620 is fixedly connected to the side of the compartment 300 far from the filter screen 610. The biological membrane 620 is formed by microorganisms. After the sewage is treated by the microbial community, it is further treated by the biological membrane 620. The biological membrane 620 and the filter screen 610 isolate the area between the plant roots, reducing the rapid loss of the microbial community.

[0071] There are multiple layers of wire meshes 630 arranged within the partition layer 300. The multiple layers of wire meshes 630 stratify the plant roots, reduce the interlacing of roots between layers, and restrict the plant roots. The wire mesh 630 is made of an elastic material, and the side away from the bottom wall of the partition layer 300 is wavy, forming an elastic part 631. The elastic part 631 bends in the vertical direction to form waves, and the shape of the waves is bent multiple times along the water flow direction on the water inlet and drainage sides. The side close to the bottom wall of the partition layer 300 forms a bent part 632. The rigidity of the bent part 632 is greater than that of the elastic part 631. The elastic part 631 can shake under the flow of water, and the bent part 632 can only shake under the action of an external force. To facilitate the shaking of the bent part 632, a driving component 700 is provided on the treatment chamber 200. The driving component 700 is connected or separated from the bent part 632 and is used to drive the bent part 632 to shake periodically.

[0072] Referring to Figure 3 、 Figure 4 and Figure 5 , a plurality of mounting seats 660 are provided on the bottom wall of the treatment chamber 200. The mounting seats 660 correspond to the partition layer 300, and slots are formed on the mounting seats 660. The partition layer 300 is inserted into the slots to form a detachable connection structure; a receiving cavity 661 is formed on the side of the mounting seat 660 close to the bottom wall of the treatment chamber 200; the driving component 700 includes a rotating shaft 710 rotatably connected to the side wall of the treatment chamber 200. One end of the rotating shaft 710 extends into the treatment area and is close to the bent part 632, and the other end is located outside the treatment chamber 200 and corresponds to the water outlet end of the connecting pipe 500. The connecting pipe 500 is arranged obliquely downward and faces the end of the rotating shaft 710. An impeller 720 is fixedly connected to the end of the rotating shaft 710. The impact surface of the impeller 720 is bowl-shaped. The water ejected from the connecting pipe 500 impacts on the bowl-shaped impact surface, driving the impeller 720 to rotate; a lever 730 is fixedly connected to the end located in the treatment area. The lever 730 has elasticity. The lever 730 abuts against one side of the bent part 632. As the rotating shaft 710 rotates, the lever 730 drives the bent part 632 to be bent under force. After bending to a certain extent, the lever 730 deforms, and the lever 730 separates from the bent part 632. The bent part 632 returns to its original position and drives the elastic part 631 to vibrate; and the rotating shaft 710 is in the receiving cavity 661, and the lever 730 slightly disturbs the water flow, reducing excessive sedimentation at the bottom.

[0073] A clamping groove is formed on the bottom wall of the processing chamber 200. The mounting seat 660 is clamped in the clamping groove and extends to the outside of the processing chamber 200. A communication hole is formed at one end of the mounting seat 660 close to the interlayer 300. A partition plate 640 is fixedly connected to one side of the communication hole close to the interlayer 300. The partition plate 640 blocks the communication between the inside of the processing chamber 200 and the accommodating cavity 661. The partition plate 640 and the accommodating cavity 661 cooperate to form a precipitation area. A slag inlet hole 641 is formed on the partition plate 640. The slag inlet hole 641 communicates the processing area with the accommodating cavity 661. A slag discharge hole 662 is formed on the bottom wall of the mounting seat 660. The slag discharge hole 662 communicates the accommodating cavity 661 with the outside of the processing chamber 200. A second sealing plate 680 is slidably connected to the partition plate 640. A second blocking hole 681 is formed on the second sealing plate 680. The second blocking hole 681 corresponds to the slag inlet hole 641 and can be communicated with the slag inlet hole 641 as it slides. A first sealing plate 670 is slidably connected to the bottom wall of the mounting seat 660. A first blocking hole 671 is formed on the first sealing plate 670. The first blocking hole 671 corresponds to the slag discharge hole 662 and can be communicated with the slag discharge hole 662 as it slides. The slag inlet hole 641 and the slag discharge hole 662 are alternately opened. A deflector plate 650 is fixedly connected to the mounting seat 660. The deflector plate 650 extends towards the sewage pool and is used to guide the outflowing precipitate.

[0074] Sliding rods are fixedly connected to both the first sealing plate 670 and the second sealing plate 680. The sliding rods extend out of the mounting seat 660 and are fixedly connected to a limiting plate 750. A resetting member 740 is arranged on the limiting plate 750. The resetting member 740 can be a spring. The resetting member 740 is connected to the outer side wall of the mounting seat 660 and drives the sliding rod 690 to slide away from the mounting seat 660. A pushing assembly 800 is arranged on the processing chamber 200. The pushing assembly 800 can be connected to the limiting plate 750 and drives the limiting plate 750 to slide.

[0075] The pushing assembly 800 includes a reciprocating screw rod 810 coaxially and fixedly connected to a rotating shaft 710. A slider 820 is threadedly connected to the reciprocating screw rod 810. The slider 820 slides on the processing chamber 200 and approaches or moves away from the mounting seat 660. The slider 820 can abut against the limiting plate 750 corresponding to the second sealing plate 680 and drive the limiting plate 750 to slide. A sliding ring 830 is coaxially and slidably connected to the rotating shaft 710. A cam 840 is coaxially and fixedly connected to the sliding ring 830. The cam 840 can abut against the limiting plate 750 corresponding to the first sealing plate 670. During the sliding process of the slider 820, it can abut against the sliding ring 830 and drive the sliding ring 830 to slide. As the cam 840 rotates, it separates from the limiting plate 750 connected to the first sealing plate 670, so that the resetting member 740 drives the first sealing plate 670 to block the slag discharge hole 662.

[0076] To facilitate the drainage of water in the treatment chamber 200, a pressure pump may be provided on the connecting pipe 500 for pumping the water in the treatment chamber 200; to facilitate the protection of the reciprocating screw 810, a protective cover 910 may be provided to cover and protect the reciprocating screw 810, the slider 820, the slip ring 830, the limiting plate 750, and the sliding rod 690.

[0077] The implementation principle of the embodiment of the present application is as follows: all parts of the device are in the initial position, and the reset member 740 (such as a spring) makes the first sealing plate 670 and the second sealing plate 680 both in the initial sealing position; the storage chamber 100 has stored the sewage to be treated, and all valves are in the closed state; the valve on the connecting pipe 110 between the storage chamber 100 and the treatment chamber 200 is opened, and the sewage flows from the storage chamber 100 into the treatment chamber 200 through the bent connecting pipe 110 due to gravity. Since the connection position of the connecting pipe 110 and the treatment chamber 200 is on one side close to the bottom of the treatment chamber 200, the sewage first enters the bottom of the treatment chamber 200.

[0078] The sewage in the treatment chamber 200 is treated by the microbial community, the filter screen 610, and the biofilm 620 in the partition layer 300. The microbial community adheres to the plant roots to decompose and purify the sewage, and the sewage stays in the treatment chamber 200 for treatment; the filter screen 610 filters out larger impurities, and the biofilm 620 further treats the sewage to improve the water quality.

[0079] When the treated sewage is discharged into the clean water tank 400 through the connecting pipe 500, since the connecting pipe 500 is arranged obliquely downward and towards the end of the rotating shaft 710, the force of the water jet impacts on the bowl-shaped impact surface of the impeller 720, driving the impeller 720 and the rotating shaft 710 to rotate; the rotating shaft 710 drives the lever 730 to rotate, and the lever 730 abuts against the bent portion 632 and causes it to be bent under force. After the lever 730 is bent to a certain extent, it deforms and separates from the bent portion 632. The bent portion 632 returns to its original position and drives the elastic portion 631 to vibrate, which helps to evenly distribute the microbial community and prevent rapid loss, and can shake off the formed precipitate and deposit it in the accommodating cavity 661; the precipitate generated during the treatment process accumulates at the bottom of the treatment chamber 200. As the rotating shaft 710 rotates, the pushing assembly 800 starts to work; the slider 820 on the reciprocating screw 810 slides under the drive of the rotating shaft 710. First, it abuts against the limiting plate 750 corresponding to the second sealing plate 680 and pushes it to slide, opening the communication between the second blocking hole 681 and the slag inlet hole 641, allowing the precipitate to enter the accommodating cavity 661; subsequently, during the sliding process, the slider 820 abuts against the slip ring 830 and drives it to slide, and the cam 840 abuts against the limiting plate 750 corresponding to the first sealing plate 670, pushing the first sealing plate 670 to slide, opening the communication between the first blocking hole 671 and the slag discharge hole 662, allowing the precipitate in the accommodating cavity 661 to be discharged to the sewage discharge pool outside the treatment chamber 200; the slag inlet hole 641 and the slag discharge hole 662 are alternately opened and closed under the action of the pushing assembly 800, realizing the continuous treatment and discharge of the precipitate.

[0080] The treated clean water falls into the clean water tank 400 after contacting the impeller 720 for subsequent use or recycling.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
