Description

TECHNICAL FIELD

[0001] The present application relates to the field of energy saving and environmental protection sewage treatment, and particularly relates to an in-situ purification and ecological restoration device for a river sewage outlet. BACKGROUND

[0002] With the continuous acceleration of urbanization process in China, the construction scale of urban drainage system is also increasing year by year. The urban drainage system is an important part of the urban lifeline, which undertakes the functions of collecting, transporting and discharging urban domestic sewage, industrial wastewater and rainwater runoff.

[0003] With the continuous acceleration of urbanization process in China, the construction scale of urban drainage system is also increasing year by year. The end of the urban drainage system is the river sewage outlet located along the river. The effluent pollution of these river sewage outlets is the total root cause of urban river water pollution and eutrophication, and even black odor. This is because the combined system drainage pipeline has accumulated a large amount of sludge due to small flow during "sunny days"; the rainwater pipeline of the separated system also has the problem of sludge accumulation due to the problem of sewage pipeline mixing. When "rainy days" come, the sludge accumulated in the pipeline is washed into the river sewage outlet and into the surface water, causing eutrophication and even black odor. Therefore, the surface water receiving the river sewage outlet usually presents the phenomenon of "clear on sunny days and black on rainy days", so it is urgent to implement timely and efficient purification for the rainy day pollution problem of the river sewage outlet.

[0004] In summary, the market urgently needs a new device that can solve the effluent pollution problem of the river sewage outlet at the end of the urban drainage system, the food chain construction and water ecological system restoration of the surface water receiving the river sewage outlet. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the defect of repeated pollution of the water body of the river sewage outlet in the prior art, and to provide an in-situ purification and ecological restoration device for the river sewage outlet.

[0006] The present application solves the above technical problems by the following technical solutions:

[0007] The device for in-situ purification and ecological restoration of sewage outlet into river comprises a purification assembly, a restoration assembly, a control assembly and a device body, the device is arranged at the sewage outlet to make the sewage flow into the device body; the purification assembly comprises a first conveying part in communication with the device body; the restoration assembly comprises a second conveying part in communication with the device body; when the control assembly monitors that the device is in a first mode, the control assembly controls the first conveying part to work to make the purification assembly in communication with the device body; when the control assembly monitors that the device is in a second mode, the control assembly controls the second conveying part to work to make the restoration assembly in communication with the device body.

[0008] In the scheme, the sewage at the sewage outlet flows into the device body, and the control assembly is the intelligent control center of the device. It can monitor the state of the device and decide which mode to take according to the monitoring result. In the first mode, the control assembly controls the first conveying part to work to make the purification assembly in communication with the device body, and the sewage in the device body is purified; in the second mode, the control assembly controls the second conveying part to work to make the restoration assembly in communication with the device body, and the sewage discharged into the device is restored. On the one hand, the purified water can be discharged into the surface water body, and on the other hand, the water after ecological restoration can be discharged into the surface water body. The device can efficiently purify, deodorize, disinfect and condition the water discharged from the sewage outlet into river, avoid the diffusion pollution of the sewage outlet into river to the surface water body, has the functions of water quality purification, ecological restoration, slag gathering and slag removing, and is beneficial to the construction of food chain and the recovery of ecological system of the surface water body.

[0009] Preferably, the restoration assembly further comprises filler blocks; the device body comprises a cylinder; the device further comprises at least two ultraviolet lamp tubes, a plurality of filler blocks are arranged on the inner side wall of the cylinder in a spaced manner, and a plurality of ultraviolet lamp tubes are arranged on the inner side wall of the cylinder in a spaced manner; the device further comprises a spray pipe, a first material conveying pipe and a second material conveying pipe, the inlet of the first material conveying pipe is in communication with the first conveying part, and the outlet of the first material conveying pipe is in communication with the spray pipe; the inlet of the second material conveying pipe is in communication with the second conveying part, and the outlet of the second material conveying pipe is in communication with the spray pipe; the spray pipe is arranged in a ring shape, and a plurality of outlets are arranged on the bottom wall of the spray pipe in a spaced manner; along the height direction of the device body, the spray pipe is located above the filler blocks.

[0010] In this scheme, the addition of the filler blocks can significantly improve the treatment effect of the device. The filler blocks provide a larger surface area, which can provide more growth areas for biodegradation during wastewater purification or remediation, promote microbial attachment and activity, and thus accelerate the decomposition of organic matter in wastewater, the removal of new pollutants, and the purification of other pollutants, especially new pollutants such as persistent organic pollutants, antibiotics, and endocrine disruptors. The device body is designed as a cylinder, which can provide appropriate space for each component so that they can be reasonably arranged within the device. The cylinder not only accommodates filler blocks, UV lamp tubes, and spray pipes, but also helps the flow and treatment of wastewater within the device. At least two UV lamp tubes are arranged along the circumference of the cylinder, which can sterilize microorganisms when wastewater flows through the device. The radiation of ultraviolet light can effectively destroy the nucleic acids of microorganisms, thereby eliminating bacteria, viruses, and other microorganisms and reducing the risk of pollution to surface water bodies. The first and second feed pipes are responsible for guiding the flow of the medicament. The annular design of the spray pipe and the multiple outlets at the bottom, as well as the location of the spray pipe above the filler blocks, can allow the medicament sprayed through the spray pipe to fall above the filler blocks, avoiding waste of the medicament and allowing it to contact the wastewater more fully, thereby increasing the purification and disinfection effect.

[0011] Preferably, when the control assembly detects that the device is in the first mode, the light wavelength of the UV lamp tube is set to 100-400 nm; when the control assembly detects that the device is in the second mode, the light wavelength of the UV lamp tube is set to 400-760 nm.

[0012] In this scheme, the light wavelength of the UV lamp tube changes in different treatment modes. When the device is in the first mode, the control assembly detects this state and adjusts the light wavelength of the UV lamp tube to 100-400 nm, which is in the shorter wavelength range of the ultraviolet spectrum, known as short-wave ultraviolet light (UV-C). This ultraviolet light has high energy at a shorter wavelength and can destroy the nucleic acids of microorganisms, thereby effectively killing bacteria, viruses, and other microorganisms and achieving disinfection. When the device is in the second mode, the control assembly detects this state and adjusts the light wavelength of the UV lamp tube to 400-760 nm, which is in the range between visible light and near-ultraviolet light, including visible light and part of the near-ultraviolet light spectrum. This wavelength range is suitable for photosynthesis and can promote the degradation and decomposition of biological substances in water, achieving remediation and purification. By using different ultraviolet wavelengths in different treatment modes, different treatment effects can be achieved. In the first mode, short-wave ultraviolet light can effectively disinfect and eliminate microorganisms; in the second mode, longer wavelengths can promote photosynthesis and biodegradation. This adjustment can provide the device with more precise and effective treatment methods according to different treatment needs, thereby achieving better wastewater purification and remediation effects.

The flow guide bottom plate guides the water flow and directs the sewage entering the device to the lower part, which helps the effective progress of each treatment stage; the workbench provides a support platform for other components, which helps the structural stability and assembly of the device. The inner diameter of the cylinder is greater than the diameter of the spray pipe, which facilitates the installation of the spray pipe inside the cylinder and prevents the medicine from being sprayed outside the cylinder, achieving effective spraying and mixing, thereby better mixing the medicine with the sewage and increasing the purification effect. The floating bodies are arranged in multiple and are arranged in a circumferential direction of the cylinder to provide buoyancy to the device. The introduction of the floating bodies helps the device to float on the water surface, allowing it to float freely in the water.

[0016] and / or,

[0017] The second conveying part comprises a second storage tank and a second metering pump, the second storage tank is used to store the repair medicine; the second storage tank is in communication with the inlet of the second conveying pipe, and the second metering pump is arranged between the second storage tank and the inlet of the second conveying pipe, so that when the second metering pump is operated, the purification medicine can enter the spray pipe from the second conveying pipe.

[0018] In this scheme, the first storage tank in the first conveying part stores the purification reagent, and the second storage tank in the second conveying part stores the repair reagent. By setting the metering pump, accurate metering and addition of the reagent can be realized, which improves the correct amount of reagent and thus improves the efficiency and accuracy of the treatment. Since the first conveying part and the second conveying part are used for purification reagent and repair reagent respectively, the device can introduce different types of reagents according to actual processing needs. Such design makes the device more flexible to achieve the purification and repair goals under different sewage conditions. By setting the metering pump, the reagent can be automatically added as needed without manual intervention. This automatic addition improves the stable input of the reagent, reduces the risk of human operation, and can achieve quantitative reagent input at different processing stages. By controlling the operation of the metering pump, the addition rate and addition time of the reagent can be accurately controlled. Accurate control helps to optimize the treatment process and improve the mixing of the reagent and sewage to achieve better purification and repair effect.

[0019] Preferably, the control assembly comprises a monitoring member and an electric control box, the electric control box is arranged on the surface of the workbench of the device body, the monitoring member is arranged in the cavity of the cylinder, and the ultraviolet lamp tube, the first metering pump and the second metering pump are electrically connected with the electric control box; the monitoring member is arranged at the center of the cylinder.

[0020] In this scheme, the control assembly plays a role in intelligent control and monitoring in the device. The monitoring member is responsible for monitoring the corresponding parameters, and the electric control box is responsible for real-time control of the operation of the device according to the monitoring results. This design enables the device to automatically operate according to actual conditions, improving the processing efficiency and effect. The electric control box is arranged on the surface of the workbench of the device body. This position selection makes the electric control box easily electrically connected with other components and located in a place easy for the operator to operate, facilitating maintenance and adjustment. The monitoring member is arranged in the cavity of the cylinder and at the center of the cylinder. This position setting enables the monitoring member to more accurately perceive the state inside the device, thus realizing more accurate control and monitoring. The ultraviolet lamp tube, the first metering pump and the second metering pump are electrically connected with the electric control box, so that these key components can communicate information and execute instructions with the electric control box, ensuring that all parts of the device can work in coordination to achieve the expected treatment effect, thus realizing more efficient and stable sewage purification and repair effect.

[0021] Preferably, the device further comprises a push flow assembly; the push flow assembly comprises a rotating motor, a speed regulating hand wheel, a connecting rod and a push flow impeller, the speed regulating hand wheel is connected with the rotating motor, and the rotating motor is connected with an electric control box; the rotating motor is arranged on the surface of the workbench, one end of the connecting rod above the workbench is connected with the outlet end of the rotating motor, and the other end of the connecting rod in the chamber of the cylinder is connected and fixed with the push flow impeller; the connecting rod can be elongated and compressed along the axial direction thereof; and along the height direction of the cylinder, the bottom of the push flow impeller is higher than the top of the ultraviolet lamp tube.

[0022] In the scheme, the push flow assembly is used to promote the movement and mixing of water flow during sewage treatment, so as to achieve more uniform mixing, purification and repair effects of the medicament; the rotating motor drives the movement of the push flow assembly; the speed regulating hand wheel is connected with the rotating motor, so that the rotating speed of the motor can be adjusted to control the movement speed of the push flow impeller, so that the water flow can be moderately stirred to achieve an optimized mixing effect; and the design of the connecting rod allows it to be elongated and compressed along the axial direction. This design allows the connecting rod to be adjusted as needed to adapt to different water level changes, so that the push flow impeller is always located at the appropriate position; the push flow impeller is located in the chamber of the cylinder, and the bottom thereof is higher than the top of the ultraviolet lamp tube. Such a design allows the push flow impeller to produce stirring effect in the water flow in the device without interfering with the normal operation of the ultraviolet lamp tube, thereby improving the purification and repair effects of the sewage and helping to achieve optimized circulation of the water flow in the device to ensure uniform distribution and action of the medicament and achieve better treatment effects.

[0023] Preferably, the device further comprises a filter screen; along the height direction of the device body, the two ends of the filter screen are respectively abutted with the top wall of the cylinder and the lower surface of the workbench to filter the water flow entering the chamber of the cylinder from between the workbench and the cylinder; a plurality of through holes penetrating the workbench are arranged at intervals along the circumferential direction of the workbench, and each through hole is arranged between two adjacent floating bodies.

[0024] In the scheme, the filter screen is used to filter the water flow entering the chamber of the cylinder from between the workbench and the cylinder, which can effectively prevent impurities, solid particles and the like from entering the interior of the cylinder to protect the components inside the device from being blocked and damaged, thereby prolonging the service life of the device. The through holes are arranged on the workbench and located between two adjacent floating bodies, which can have an avoidance effect when the through holes are in the working state, and the plurality of through holes arranged at intervals along the circumferential direction of the workbench allow the operator to clean the filter screen through the through holes without disassembling the filter screen, thereby saving time and effort.

[0025] Preferably, the device further comprises at least two adjusting rods; a plurality of adjusting rods are arranged at intervals along the circumferential direction of the workbench; and each adjusting rod is slidably connected with the workbench, the cylinder and the flow guide bottom plate in sequence.

[0026] In this scheme, the design of the adjusting rod allows the height between the workbench, the cylinder and the flow guide bottom plate to be adjusted. By adjusting the length of the adjusting rod, the relative positions of the various parts of the device can be changed, such as adjusting the height difference between the cylinder and the workbench, and the height difference between the flow guide bottom plate and the cylinder. This height adjustment design can adapt to different water level conditions, ensuring that the device can always operate normally and is not affected by the water level. The sliding connection of the adjusting rod allows the workbench, the cylinder and the flow guide bottom plate to be stably connected together. This design ensures that the various components of the device can be tightly matched and will not loosen or fall off, improving the stability and reliability of the device and making it easier to adjust the height of the device. Maintenance personnel can adjust the height of the device by adjusting the length of the adjusting rod, without the need for complex operation steps, saving operation time and effort.

[0027] Preferably, the device further comprises inner and outer flow uniformizing plates; a plurality of outer flow uniformizing plates are arranged along the outer sidewall of the cylinder, and a plurality of inner flow uniformizing plates are arranged along the inner sidewall of the cylinder; the filler blocks and the ultraviolet lamp tubes are arranged between the inner flow uniformizing plates; and the control assembly further comprises a liquid level monitor for monitoring the amount of medicament in the first and second storage tanks, and the liquid level monitor is electrically connected to the electric control box.

[0028] In this scheme, the inner and outer flow uniformizing plates are arranged on the inner and outer sidewalls of the cylinder, respectively, which helps to optimize the distribution and flow of water. The presence of the inner flow uniformizing plates allows the water flow to be further uniformly distributed inside the cylinder, while the outer flow uniformizing plates help to guide the water flow outside the cylinder, allowing the water flow to flow more uniformly in the inner and outer regions. This design improves the uniformity of the flow inside and outside the device, thereby enhancing the mixing and effect of the medicament and sewage. The filler blocks and ultraviolet lamp tubes are arranged between the inner flow uniformizing plates, which increases the contact opportunities between the medicament and the water flow during their interaction. The filler blocks provide more surface area, allowing the medicament to contact the water flow more fully, while the arrangement of the ultraviolet lamp tubes allows the water flow to be treated at a specific wavelength, helping to kill bacteria and microorganisms, thereby improving the purification effect of the sewage. The introduction of the liquid level monitor allows the device to monitor the amount of medicament in the first and second storage tanks in real time. This design can avoid the occurrence of medicament depletion or excess, thereby ensuring stable supply of medicament and ensuring continuous and efficient operation of the device. The liquid level monitor is electrically connected to the electric control box, allowing the liquid level monitor to transmit the status information of the medicament to the electric control box. Such real-time monitoring and control helps to maintain the normal operation of the device and the management of the medicament, improving the treatment effect. Therefore, not only is the uniformity of the water flow and the contact effect of the medicament enhanced, but also the management of the medicament and the stable operation of the device are optimized, further improving the sewage purification and repair effect of the device.

[0072] Please refer to Figures 1 to 6 , the in-situ purification and ecological restoration device 1000 of the sewage outlet into the river, the device 1000 includes a purification assembly, a repair assembly, a control assembly and a device body, the device 1000 is arranged at the sewage outlet 100 to make the sewage flow into the device body; the purification assembly includes a first conveying part, the first conveying part is in communication with the device body; the repair assembly includes a second conveying part, the second conveying part is in communication with the device body; when the control assembly monitors that the device 1000 is in the first mode, the control assembly controls the first conveying part to work to make the purification assembly in communication with the device body; when the control assembly monitors that the device 1000 is in the second mode, the control assembly controls the second conveying part to work to make the repair assembly in communication with the device body.

[0073] In the present embodiment, as Figure 6As shown, the device 1000 is arranged at the sewage outlet 100 so that sewage flows into the device body, and the control assembly is the intelligent control center of the device 1000. The state of the device 1000 and the sewage can be monitored through the control assembly, and the mode to be adopted is determined according to the monitoring result. For example, in the first mode, the control assembly controls the first conveying part to work, so that the purification assembly is in communication with the device body, and the sewage in the device body is purified. In the second mode, the control assembly controls the second conveying part to work, so that the repair assembly is in communication with the device body, and the sewage discharged into the device is repaired. On the one hand, the purified water can be discharged into the surface water body, and on the other hand, the water after the ecological repair work can be discharged into the surface water body. The device can efficiently purify, deodorize, disinfect and condition the water discharged from the sewage outlet into the river, avoid the diffusion pollution of the sewage outlet into the river to the surface water body, and has the functions of water quality purification, ecological restoration, slag gathering and slag removing, which is beneficial to the construction of food chain and the recovery of ecological system of the surface water body.

[0074] As shown in the first mode, Figures 2 to 4 As shown, the repair assembly further comprises a filler block 203, the device body comprises a cylinder 2, the device 1000 further comprises at least two ultraviolet lamp tubes 6, a plurality of filler blocks 203 are arranged on the inner side wall of the cylinder 2 in a circumferential direction of the cylinder 2, and a plurality of ultraviolet lamp tubes 6 are arranged on the inner side wall of the cylinder 2 in a circumferential direction of the cylinder 2; the device 1000 further comprises a spray pipe 8, a first feeding pipe 301 and a second feeding pipe 201, the inlet of the first feeding pipe 301 is in communication with the first conveying part, and the outlet of the first feeding pipe 301 is in communication with the spray pipe 8; the inlet of the second feeding pipe 201 is in communication with the second conveying part, and the outlet of the second feeding pipe 201 is in communication with the spray pipe 8; the spray pipe 8 is arranged in a ring shape, and a plurality of outlets are arranged on the bottom wall of the spray pipe 8 in a spaced manner. The spray pipe 8 is located above the filler block 203 in the height direction of the device body.

[0075] In this embodiment, the spray pipe 8 above the filler block 203 is arranged as a ring-shaped spray pipe 8, so that it can better work with the filler blocks 203 arranged along the inner wall of the cylinder 2. When the ring-shaped spray pipe 8 sprays, the medicament sprayed from the through hole 14 below it just falls on the surface of the filler block 203 below the spray pipe 8, avoiding waste of the medicament and enabling it to be more fully in contact with the sewage, thereby increasing the purification and disinfection effect; the multiple outlets of the spray pipe 8 can increase the amount of medicament delivered per unit time and improve the efficiency of purifying sewage and restoring water quality. The addition of these filler blocks 203 can significantly improve the treatment effect of the device. The filler blocks 203 provide more surface area, which can provide more growth area for the biodegradation process during sewage purification or restoration, promote microbial attachment and activity, and thus accelerate the decomposition of organic matter in the sewage, the removal of new pollutants and the purification of other pollutants, especially persistent organic pollutants, antibiotics, endocrine disruptors and other new pollutants. In this embodiment, the filler block 203 is made of a porous corrosion-resistant material to further improve the service life of the filler block 203. The device body is designed as a cylinder 2, which can provide appropriate space for each component so that they can be reasonably arranged in the device. The cylinder 2 not only accommodates the filler block 203, the ultraviolet lamp tube 6, the spray pipe 8, etc., but also helps the flow and treatment of the sewage in the device. At least two ultraviolet lamp tubes 6 are arranged along the circumference of the cylinder 2, which can sterilize microorganisms when the sewage flows through the device. The radiation of ultraviolet light can effectively destroy the nucleic acid of microorganisms, thereby eliminating bacteria, viruses and other microorganisms and reducing the risk of pollution to surface water bodies. The first and second feed pipes 301 and 201 are responsible for guiding the flow of medicament.

[0076] In this embodiment, the ultraviolet lamp 6 is arranged in the chamber of the barrel 2 through the lamp tube mounting seat 61. When the control assembly monitors that the device 1000 is in the first mode, the illumination wavelength of the ultraviolet lamp 6 is set to 100-400 nm; when the control assembly monitors that the device 1000 is in the second mode, the illumination wavelength of the ultraviolet lamp 6 is set to 400-760 nm. In different processing modes, the illumination wavelength of the ultraviolet lamp 6 changes, thereby producing different technical effects. When the device 1000 is in the first mode, the control assembly monitors this state and adjusts the illumination wavelength of the ultraviolet lamp 6 to 100-400 nm. This wavelength range is in the shorter waveband of the ultraviolet spectrum, called shortwave ultraviolet (UV-C). This ultraviolet light has very high energy at a shorter wavelength and can destroy the nucleic acids of microorganisms, thereby effectively killing bacteria, viruses and other microorganisms and achieving a disinfection effect. When the device 1000 is in the second mode, the control assembly monitors this state and adjusts the illumination wavelength of the ultraviolet lamp 6 to 400-760 nm. This wavelength range is between the visible spectrum and near ultraviolet and includes part of the visible and near ultraviolet spectrum. This wavelength range is suitable for photosynthesis and can promote the degradation and decomposition of biological substances in water, thereby achieving repair and purification effects. By using different ultraviolet wavelengths in different processing modes, different processing effects can be achieved. In the first mode, shortwave ultraviolet light can effectively disinfect and eliminate microorganisms; in the second mode, longer wavelengths are helpful for photosynthesis and biological degradation. This adjustment can provide the device 1000 with more accurate and effective processing means according to different processing requirements, thereby achieving better sewage purification and repair effects.

[0077] As Figure 2 to as Figure 4As shown, the device body includes a workbench 1 and a flow guide bottom plate 9; along the height direction of the device body, the flow guide bottom plate 9, the cylinder 2 and the workbench 1 are sequentially arranged, and a spacing distance is arranged between the cylinder 2 and the workbench 1 and the flow guide bottom plate 9 to allow water flow to pass through; the inner diameter of the cylinder 2 is greater than the diameter of the spray pipe 8; the device body further includes a plurality of floating bodies 12, which are arranged in the circumferential direction of the cylinder 2 and are arranged at intervals to provide buoyancy for the device 1000. The workbench 1 and the flow guide bottom plate 9 are respectively arranged at the upper and lower parts of the device, forming a vertical structure. The flow guide bottom plate 9 guides the water flow and guides the sewage entering the device to the lower part, which helps the effective progress of each treatment stage; the workbench 1 provides a support platform for other components, which helps the structural stability and assembly of the device. The inner diameter of the cylinder 2 is greater than the diameter of the spray pipe 8, which facilitates the installation of the spray pipe 8 in the interior of the cylinder 2 and prevents the reagent from being sprayed outside the cylinder 2, thereby achieving effective spraying and mixing, and better mixing of the reagent and sewage, thereby increasing the purification effect. In this embodiment, the top and bottom of the cylinder 2 are open, the side wall is sealed, the flow guide bottom plate 9 has a conical shape; the workbench 1 is made of transparent rigid material; and the service life of the device 1000 is further prolonged.

[0078] The floating bodies 12 are arranged at intervals in the circumferential direction of the cylinder 2 through the floating body mounting seat 11 to provide buoyancy for the device 1000. The introduction of the floating bodies 12 helps the device to float on the water surface, allowing it to float freely in the water. This makes the device easier to install and maintain, and also allows adjustment according to changes in water level. In this embodiment, the several floating bodies 12 have the same specifications and a density much lower than water, and can carry the in-situ purification and ecological restoration device for river sewage discharge outlets to float on the water surface. Each two adjacent floating bodies 12 have a gap of 0.2 m or more.

[0079] In this embodiment, the first conveying part includes a first storage tank 302 and a first metering pump 303, the first storage tank 302 is used to store purification reagents; the first storage tank 302 is in communication with the inlet of the first conveying pipe 301, and the first metering pump 303 is arranged between the first storage tank 302 and the inlet of the first conveying pipe 301, so that when the first metering pump 303 is operated, the purification reagents can enter the spray pipe 8 from the conveying pipe; the second conveying part includes a second storage tank 202 and a second metering pump 204, the second storage tank 202 is used to store restoration reagents; the second storage tank 202 is in communication with the inlet of the second conveying pipe 201, and the second metering pump 204 is arranged between the second storage tank 202 and the inlet of the second conveying pipe 201, so that when the second metering pump 204 is operated, the purification reagents can enter the spray pipe 8 from the second conveying pipe 201.

[0080] The first storage tank 302 in the first conveying part stores the purification agent, and the second storage tank 202 in the second conveying part stores the repair agent. By setting the metering pump, accurate metering and addition of the agent can be realized, which improves the correct amount of agent and thus improves the efficiency and accuracy of the treatment. Since the first conveying part and the second conveying part are used for purification agent and repair agent respectively, the device can introduce different types of agents according to actual processing needs. Such design makes the device more flexible to achieve the goal of purification and repair under different sewage conditions. By setting the metering pump, the agent can be automatically added as needed without manual intervention. This automatic addition improves the stable input of the agent, reduces the risk of human operation, and can achieve quantitative agent input at different processing stages. By controlling the operation of the metering pump, the addition rate and addition time of the agent can be accurately controlled. Precise control helps to optimize the treatment process and improve the mixing of the agent and sewage to achieve better purification and repair effect.

[0081] The control assembly includes a monitoring member 401 and an electric control box 3. The electric control box 3 is arranged on the surface of the workbench 1 of the device body, and a solar photovoltaic panel 4 is installed on the top of the electric control box 3. The solar photovoltaic panel 4 can provide power for the device such as the electric control box 3, which is more environmentally friendly. The monitoring member 401 is arranged inside the cavity of the cylinder 2, and the ultraviolet lamp tube 6, the first metering pump 303 and the second metering pump 204 are electrically connected with the electric control box 3. The monitoring member 401 is arranged at the center of the cylinder 2. The control assembly plays a role of intelligent control and monitoring in the device 1000. The monitoring member 401 is responsible for monitoring the corresponding parameters, and the electric control box 3 is responsible for real-time control of the operation of the device according to the monitoring results. This design enables the device to automatically operate according to the actual situation, improving the processing efficiency and effect. The electric control box 3 is arranged on the surface of the workbench 1 of the device body. This position selection makes the electric control box 3 easily electrically connected with other components and easily accessed by the operator, facilitating maintenance and adjustment. The monitoring member 401 is arranged inside the cavity of the cylinder 2 and at the center of the cylinder 2. This position setting enables the monitoring member 401 to more accurately perceive the state inside the device, thereby realizing more accurate control and monitoring. The ultraviolet lamp tube 6, the first metering pump 303 and the second metering pump 204 are electrically connected with the electric control box 3 and the solar photovoltaic panel 4, so that these key components can transmit information and execute instructions with the electric control box 3, ensuring that all parts of the device can work in coordination to achieve the expected treatment effect, thereby realizing more efficient and stable sewage purification and repair effect.

[0082] As Figure 4As shown, the device 1000 also includes a push flow assembly 10 made of corrosion-resistant steel material; in other alternative embodiments, the push flow assembly 10 can also be made of other beneficial materials. The push flow assembly 10 includes a rotating motor 102, a speed regulating hand wheel 103, a connecting rod 101, and a push flow impeller 104. The speed regulating hand wheel 103 is connected to the rotating motor 102, and the rotating motor 102 is connected to the electric control box 3. The rotating motor 102 is arranged on the surface of the workbench 1. One end of the connecting rod 101 above the workbench 1 is connected to the outlet end of the rotating motor 102, and the other end of the connecting rod 101 inside the chamber of the cylinder 2 is connected and fixed to the push flow impeller 104. The connecting rod 101 can be elongated and compressed along its axis. Along the height direction of the cylinder 2, the bottom of the push flow impeller 104 is higher than the top of the ultraviolet lamp 6. The push flow assembly 10 is designed to promote the movement and mixing of water flow during the sewage treatment process, thereby achieving more uniform mixing, purification, and restoration effects of the reagents. The direction and speed of the rotating motor 102 can be adjusted. The rotating motor 102 drives the movement of the push flow assembly 10. The speed regulating hand wheel 103 is connected to the rotating motor 102, which can adjust the speed of the motor, thereby controlling the speed of the push flow impeller 104, allowing the water flow to be moderately stirred to achieve optimal mixing effect. The design of the connecting rod 101 allows it to be elongated and compressed along the axis. This design allows the connecting rod 101 to be adjusted as needed to adapt to different water level changes, thereby keeping the push flow impeller 104 always in the right position. The push flow impeller 104 is located inside the chamber of the cylinder 2, and its bottom is higher than the top of the ultraviolet lamp 6. This design allows the push flow impeller 104 to produce stirring effect in the water flow inside the device without interfering with the normal operation of the ultraviolet lamp 6, thereby improving the purification and restoration effect of the sewage, helping to achieve optimal circulation of the water flow in the device, ensuring that the reagents can be evenly distributed and acted upon to achieve better treatment effect.

[0083] The device 1000 also includes a filter screen 13. Along the height direction of the device body, the two ends of the filter screen 13 are respectively in abutment with the top wall of the cylinder 2 and the lower surface of the workbench 1, for filtering the water flow entering the chamber of the cylinder 2 from between the workbench 1 and the cylinder 2. A plurality of through holes 14 are arranged on the workbench 1 in a circumferential direction, and each through hole 14 is arranged between two adjacent floating bodies 12.

[0084] The filter screen 13 is used to filter the water flow entering the chamber of the barrel 2 from the workbench 1 and the barrel 2, which can effectively prevent impurities, solid particles and the like from entering the inside of the barrel 2, thereby protecting the components inside the device from being blocked and damaged, and prolonging the service life of the device. The through hole 14 is arranged on the workbench 1 and located between two adjacent floating bodies 12, which can play a bypassing effect when the through hole 14 is in a working state. When the monitoring member 401 monitors that the water flow of the water body in the barrel 2 is low, it indicates that a large amount of floating sludge is intercepted outside the filter screen 13. At this time, the electric control box 3 sends a sludge salvage prompt to the maintenance personnel, and the maintenance personnel should timely salvage the floating sludge through the salvage hole. Without disassembling the filter screen 13, time and effort are saved.

[0085] As Figure 4 The device 1000 also includes at least two adjusting rods 15, which are arranged at intervals along the circumferential direction of the workbench 1, and each adjusting rod 15 is slidably connected to the workbench 1, the barrel 2 and the flow guide bottom plate 9 in turn. The design of the adjusting rod 15 allows the height between the workbench 1, the barrel 2 and the flow guide bottom plate 9 to be adjusted. By adjusting the length of the adjusting rod 15, the relative positions of the various parts of the device can be changed, such as adjusting the height difference between the barrel 2 and the workbench 1, and the height difference between the flow guide bottom plate 9 and the barrel 2. This height adjustment design can adapt to different water level conditions and ensure that the device can always operate normally and is not affected by the water level. The sliding connection mode of the adjusting rod 15 allows the workbench 1, the barrel 2 and the flow guide bottom plate 9 to be stably connected together. This design ensures that the various components of the device can be tightly matched and will not loosen or fall off, improving the stability and reliability of the device and making it easier to adjust the height of the device. Maintenance personnel can adjust the height of the device by adjusting the length of the adjusting rod 15, without the need for complex operation steps, saving operation time and effort.

[0086] In this example, the device 1000 also includes inner flow uniformity plates 22 and outer flow uniformity plates 21; a plurality of outer flow uniformity plates 21 are arranged along the outer sidewall of the cylinder 2, and a plurality of inner flow uniformity plates 22 are arranged along the inner sidewall of the cylinder 2; the filler blocks 203 and the ultraviolet lamp tubes 6 are arranged between the inner flow uniformity plates 22; the control assembly further includes a liquid level monitor for monitoring the amount of medicament in the first storage tank 302 and the second storage tank 202, and the liquid level monitor is electrically connected to the electric control box 3. The arrangement of the inner flow uniformity plates 22 and the outer flow uniformity plates 21 on the inner sidewall and the outer sidewall of the cylinder 2, respectively, helps to optimize the distribution and flow of water. The presence of the inner flow uniformity plates 22 allows the water flow to be further uniformly distributed inside the cylinder 2, while the outer flow uniformity plates 21 help to guide the water flow outside the cylinder 2, allowing the water flow to flow more uniformly in the inner and outer areas. This design improves the uniformity of the flow inside and outside the device, thereby enhancing the mixing and effect of the medicament with the sewage. The filler blocks 203 and the ultraviolet lamp tubes 6 are arranged between the inner flow uniformity plates 22, which increases the contact opportunities between the medicament and the water flow during the interaction between the medicament and the water flow. The filler blocks 203 can provide more surface area for the medicament to contact the water flow more fully, while the arrangement of the ultraviolet lamp tubes 6 can process the water flow at a specific wavelength, which helps to kill bacteria and microorganisms, thereby improving the purification effect of the sewage. The introduction of the liquid level monitor allows the device to monitor the amount of medicament in the first storage tank 302 and the second storage tank 202 in real time. This design can avoid the situation of running out of medicament or overuse, thereby ensuring the stable supply of medicament and ensuring the continuous and efficient operation of the device. In some embodiments, the depth adjustment rod 15, the cylinder 2, the flow guide bottom plate 9, the outer flow uniformity plates 21, the inner flow uniformity plates 22, and the lamp tube mounting seat 61 are made of corrosion-resistant rigid materials.

[0087] At the same time, the liquid level monitor is electrically connected to the electric control box 3, so that the liquid level monitor can transmit the status information of the medicament to the electric control box 3. Such real-time monitoring and control helps to maintain the normal operation of the device and the management of the medicament, and improves the treatment effect. Therefore, not only the uniformity of the water flow and the contact effect of the medicament are enhanced, but also the management of the medicament and the stable operation of the device are optimized, further improving the sewage purification and repair effect of the device. In this embodiment, the first storage tank 302 and the second storage tank 202 are used to store hydrogen peroxide, chlorine dioxide solution, ozone, probiotic liquid, and beneficial algal liquid; and the first storage tank 302 and the second storage tank 202 are provided with liquid level detectors electrically connected to the electric control box 3. When the actual liquid level is lower than 20% of the full tank liquid level, the electric control box 3 will send a liquid supplement prompt to the maintenance personnel.
