It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0029] See also Figure 1-4 , the following describes an environmental pollutant wastewater treatment device according to some embodiments of the utility model.

[0030] The first aspect of the present invention provides an environmental pollutant wastewater treatment device. In some embodiments of the present invention, such as Figure 1-4 As shown, the wastewater treatment device comprises:

[0031] The wastewater tank 1 has a first inner cavity 101 formed therein, which is connected to the external wastewater transport network through a water inlet pipe; the wastewater tank 1 has a first port 102 and a second port 103 formed along the longitudinal direction, and the first port 102 and the second port 103 are respectively connected to the first inner cavity 101.

[0032] The drainage bin 2 has a second inner cavity 201 formed therein, and the second inner cavity 201 is connected to the external wastewater transport network through a water outlet pipe. The lower port and the first port 102 of the drainage bin 2 are equipped with a filter plate 3 fixed thereto. When the wastewater flows from the first inner cavity 101 to the second inner cavity 201 from bottom to top, the filter plate 3 is used to block pollutants in the wastewater and retain the pollutants in the first inner cavity 101.

[0033] The storage bin 4 is fixedly assembled with the drainage bin 2; the storage bin 4 includes a light-transmitting tube 401, which is used for external optical fiber to illuminate the interior for decomposition reaction and observation by inspection personnel, and a third inner cavity 402 is formed inside the light-transmitting tube 401; the second port 103 passes through the top of the storage bin 4 and extends to the third inner cavity 402, so that the pollutants are deposited in the third inner cavity 402 through the second port 103.

[0034] The floating rod 5 is located in the first inner cavity 101 and the second inner cavity 201; when the second inner cavity 201 is connected to the third inner cavity 402, the floating rod 5 floats inside the first inner cavity 101 and the second inner cavity 201 by the buoyancy of the wastewater; when the second inner cavity 201 is separated from the third inner cavity 402, the floating rod 5 blocks the second port 103 by the pressure of the wastewater.

[0035] The utility model provides a kind of environmental pollutant wastewater treatment device, the wastewater tank 1 is the main component of the device, and there is a space called the first inner cavity 101 inside, which is mainly used for preliminary receiving and storing wastewater transported from the outside. The first inner cavity 101 is the place for preliminary treatment and temporary storage of wastewater, and it is directly connected to the external wastewater transport network through the water inlet pipe. In this way, the continuous transportation and treatment of wastewater can be guaranteed. The water inlet pipe is a channel connecting the external wastewater transport network and the wastewater tank 1, so that wastewater can continuously flow into the wastewater tank 1 for treatment; the first port 102 and the second port 103 are arranged along the longitudinal direction of the wastewater tank 1, and are respectively connected to the first inner cavity 101, which can help the flow of wastewater in the tank and further treatment. The first port 102 is usually used for the inlet of wastewater, which may include filtering or preliminary treatment functions to help remove large particles entering the wastewater tank 1, and the second port 103 may be used as an outlet to allow the treated water to flow out for further purification steps or direct discharge.

[0036] The wastewater first enters the first inner chamber 101 through the water inlet pipe, where it may undergo preliminary physical filtration, such as using a screen to remove large solid impurities. After that, the water flows further through the first port 102, where there may be chemical or biological treatment steps, such as adding chemical reagents to reduce harmful substances or removing organic pollutants by using biological filters; the treated water finally leaves the wastewater tank 1 through the second port 103 and flows to the next treatment stage or discharge system. The water quality at this stage should have met certain discharge standards or be suitable for further use.

[0037] As a component of wastewater treatment, the drainage tank 2 is provided with a second inner cavity 201, which is the area where the wastewater is further filtered and cleaned after preliminary treatment. The second inner cavity 201 is connected to the external wastewater transportation network through an outlet pipe, allowing the treated wastewater to flow out of the device and enter the next step of treatment or discharge. The filter plate 3 is located between the bottom of the drainage tank 2 and the first port 102, and is used to intercept solid pollutants and larger suspended particles in the wastewater to prevent them from entering the second inner cavity 201, thereby improving the quality of the effluent; the filter plate 3 is fixed together with the first port 102 to ensure the stability and effectiveness of the filtration system and prevent the filter plate 3 from shifting during the treatment process.

[0038] Wastewater flows from bottom to top in the drainage bin 2. This design of water inlet at the bottom and water outlet at the top helps heavier pollutants to contact the filter plate 3 first during natural sedimentation, thereby improving filtration efficiency; when wastewater flows from the first inner cavity 101 into the second inner cavity 201 of the drainage bin 2, it must first pass through the filter plate 3. The structure and material selection of the filter plate 3 can effectively intercept solid pollutants, such as plastic fragments, organic residues, etc. The pollutants intercepted by the filter plate 3 will remain in the first inner cavity 101 or under the filter plate 3, thereby reducing the impact on subsequent treatment stages; the filter plate 3 needs to be cleaned or replaced regularly to maintain treatment efficiency. This is also part of the consideration in the facility design so that operators and maintenance personnel can easily access and handle the filter plate 3.

[0039] The storage bin 4 is fixed to the drainage bin 2 and is used to store and further process the wastewater treated by the drainage bin 2, making the wastewater treatment process more continuous and integrated; the light-transmitting tube 401 is a component installed in the storage bin 4, allowing light to penetrate into the interior. The light-transmitting tube 401 is designed mainly to support photosynthesis or photocatalysis processes and enable patrol personnel to observe the internal waste accumulation from the outside. These processes can promote chemical reactions through light energy to help decompose residual pollutants; the third inner cavity 402 is located inside the light-transmitting tube 401, and is used to centrally process pollutants introduced from the drainage bin 2 through the second port 103. The design of the third inner cavity 402 takes into account the maximum utilization of light to promote light-dependent biological or chemical treatment processes.

[0040] The pollutants in the wastewater enter the storage bin 4 through the second port 103 connected to the drainage bin 2. The second port 103 is designed to penetrate the top of the storage bin 4 and extend to the third inner cavity 402, ensuring that the pollutants can be directly transferred to the third inner cavity 402. In the third inner cavity 402, heavier pollutants can be deposited at the bottom, while lighter substances or substances that require light treatment can be further reacted and decomposed under light; the light-transmitting tube 401 allows natural light or artificial light to irradiate the third inner cavity 402, which is essential for promoting the activity of photosynthetic microorganisms or photochemical reactions. Light energy helps decompose certain difficult-to-degrade organic matter or transform certain inorganic pollutants, thereby purifying water quality; water treated by the third inner cavity 402 can be guided out of the warehouse and enter the final purification or discharge stage. This process ensures multi-stage treatment from physical, chemical to biological, and improves water treatment efficiency and water quality.

[0041] The floating rod 5 is a flexible device component, located between the first inner cavity 101 and the second inner cavity 201, and can move in the two inner cavities; when the second inner cavity 201 is connected to the third inner cavity 402, the floating rod 5 uses the buoyancy of the wastewater to float inside the first inner cavity 101 and the second inner cavity 201. This state allows the water flow to flow freely from the first inner cavity 101 to the second inner cavity 201, and continue to flow to the third inner cavity 402 for further treatment. When it is necessary to cut off the connection between the second inner cavity 201 and the third inner cavity 402, for example, when the treatment needs to limit the water flow or adjust the treatment steps, the pressure of the wastewater will push the floating rod 5 to sink, thereby blocking the second port 103. This blockage prevents the water flow from entering the third inner cavity 402, allowing more concentrated treatment in the first or second inner cavity 201; by controlling the position of the floating rod 5, the device can effectively manage the flow direction of the wastewater and the separation of the treatment area, optimize the treatment effect and prevent untreated or partially treated water from accidentally flowing into sensitive areas. Furthermore, the operation of the floating rod 5 reduces the reliance on electric or mechanical valves 7, reducing maintenance costs and potential failure points.

[0042] In summary, by setting up multiple cavities (the first cavity 101, the second cavity 201 and the third cavity 402), the continuous flow and graded treatment of wastewater are realized, and the removal efficiency of pollutants is effectively improved. Secondly, the filter plate 3 arranged between the first cavity 101 and the second cavity 201 can prevent large particles of pollutants from entering the second cavity 201, reducing the burden of downstream treatment equipment and reducing the maintenance cost of frequent replacement of filter materials. The design of the light-transmitting tube 401 introduces external illumination to promote the chemical reaction of photocatalytic decomposition of pollutants, while facilitating the inspection personnel to observe the internal situation, thereby improving the maintainability and monitoring efficiency of the system. In addition, the floating rod 5 dynamically adjusts the connection state between the second cavity 201 and the third cavity 402 by changing its position, thereby enhancing the flexibility and reliability of the treatment process. These designs not only improve the efficiency of wastewater treatment and reduce operating costs, but also improve environmental friendliness by reducing the use of chemical additives. Overall, the device provides an efficient, economical and environmentally friendly solution for wastewater treatment, significantly enhancing the performance and reliability of the system.

[0043] In any of the above embodiments, the floating rod 5 includes a central rod body 501, the central rod body 501 passes through the top of the drainage tank 2, and the filter plate 3 is arranged in an arc shape, and the filter plate 3 is arranged laterally between the central rod body 501 and the first port 102.

[0044] In this embodiment, the central rod 501 is the main part of the floating rod 5, which passes through the top of the drainage chamber 2. The design of the central rod 501 allows it to move freely in the drainage chamber 2; the filter plate 3 is designed to be arc-shaped and is arranged laterally between the central rod 501 and the first port 102. This arc-shaped design increases the filtering area, improves the ability to intercept pollutants, and helps to evenly disperse the flowing water, reducing the decrease in filtering efficiency caused by excessive local flow rate.

[0045] When the second inner cavity 201 is connected to the third inner cavity 402, the floating rod 5 floats in the drainage chamber 2 by the buoyancy of the wastewater. In this state, waste can freely pass through the space below the central rod body 501, allowing water to flow from the first inner cavity 101 to the second inner cavity 201. When it is necessary to cut off the connection between the second inner cavity 201 and the third inner cavity 402, the floating rod 5 sinks, and the central rod body 501 blocks the second port 103 by physical blocking to prevent water from entering the third inner cavity 402. The design of the arc filter plate 3 makes the filtration process more efficient, because the arc structure helps to evenly withstand the water pressure from all directions, reducing the deformation or damage of the filter plate 3 due to uneven pressure. The position and shape design of the filter plate 3 also help to capture more pollutants, especially when the water flows from bottom to top, more effectively intercepting heavy particles and other suspended matter.

[0046] Specifically, the light-transmitting tube 401 is made of acrylic material.

[0047] In any of the above embodiments, the floating rod 5 further includes a float 502 and a pressure plate 503 . The float 502 is fixedly mounted on the lower surface of the central rod body 501 , and the pressure plate 503 is fixedly mounted on the upper surface of the central rod body 501 .

[0048] The pressure plate 503 is located outside the first inner cavity 101 so that the inspection personnel can place heavy objects such as stones on the upper surface of the pressure plate 503 from the outside to drive the central rod 501 to move.

[0049] In this embodiment, the float 502 is fixedly mounted on the lower surface of the central rod body 501. The main function of the float 502 is to provide sufficient buoyancy so that the floating rod 5 can rise or remain in a floating state in the wastewater. The pressing plate 503 is fixedly mounted on the upper surface of the central rod body 501 and is located outside the first inner cavity 101. The pressing plate 503 is designed to be easily accessible and operated from the outside, allowing the inspection personnel or operators to adjust the position of the floating rod 5 by adding weight (such as placing heavy objects such as stones) on the pressing plate 503.

[0050] Under normal operating conditions, the buoyancy provided by the float 502 is sufficient to support the floating rod 5 to float in the water, allowing the water flow to freely pass through the space below the floating rod 5. When it is necessary to change the direction of the water flow or stop the water flow, the operator can increase the sinking force of the floating rod 5 by adding weight to the pressure plate 503. This weight-adding operation will cause the floating rod 5 to sink, and the central rod body 501 will move downward accordingly, thereby blocking the corresponding water flow channel; by adjusting the weight on the pressure plate 503, the operator can accurately control the position of the floating rod 5.

[0051] Specifically, the upper and lower end faces of the float 502 are conical surfaces, and a sealing rubber strip 507 is circumferentially installed on the conical surface at the lower end that is in contact with the inner wall of the first inner cavity 101 .

[0052] In any of the above embodiments, the floating rod 5 also includes a first sealing ring 504 and a second sealing ring 505. The first sealing ring 504 is fixedly mounted on the side wall of the central rod body 501, and the second sealing ring 505 is slidably mounted on the side wall of the central rod body 501 through the inner wall.

[0053] When the float 502 floats due to the buoyancy of the wastewater, the first sealing ring 504 blocks the connection gap between the central rod body 501 and the first port 102 inside the first inner cavity 101 .

[0054] When the float 502 blocks the second port 103 by the pressure of the waste water, the second sealing ring 505 blocks the connection gap between the central rod body 501 and the first port 102 outside the first inner cavity 101 .

[0055] In this embodiment, the first sealing ring 504 is fixedly installed on the side wall of the central rod body 501 to create a static seal. It is fixedly connected to the central rod body 501 and forms a close contact with the corresponding interface to prevent water flow and pollutants from leaking through any unpredicted gaps; the second sealing ring 505 is slidably installed on the side wall of the central rod body 501 through the inner wall, allowing the second sealing ring 505 to freely adjust its position as the central rod body 501 moves to adapt to dynamic sealing requirements and maintain a continuous and effective sealing effect.

[0056] The first sealing ring 504 provides the basic sealing function and is fixed in a specific position to prevent any leakage at the interface. It ensures the stability and reliability of the seal under normal operation or specific conditions (such as when the pressure increases). The second sealing ring 505 adapts to the up and down movement of the central rod 501 and automatically adjusts with the change of the rod position to ensure the integrity and no leakage of the sealing interface under various operating conditions. Its sliding characteristics enable the overall sealing system to maintain the sealing effect when the rod moves; when the water level or water pressure changes and causes the position of the central rod 501 to be adjusted, the second sealing ring 505 can slide to adapt to the new position to ensure that there is no gap due to the movement of the rod, thereby avoiding potential leakage problems. This sliding sealing design is very suitable for coping with the pressure and water level fluctuations commonly seen in the wastewater treatment process, providing additional protection measures to ensure the continuity of the treatment process and environmental safety; the materials of the first sealing ring 504 and the second sealing ring 505 are usually selected to be corrosion-resistant, wear-resistant and long-life materials.

[0057] When the float 502 rises due to the buoyancy of the wastewater, the first sealing ring 504 passively moves to a suitable position on the central rod 501 to block the connection gap between the central rod 501 and the first port 102. This design prevents wastewater from leaking through the gap, ensuring that all water flows through a predetermined path, thereby improving treatment efficiency and water quality safety; when the float 502 presses down to seal the second port 103 due to the pressure of the wastewater, the second sealing ring 505 also moves to a suitable position to block the connection gap between the central rod 501 and the first port 102 outside the first inner cavity 101. This blocking action prevents water from flowing to areas where it should not flow, such as directly entering the storage bin 4 or being discharged.

[0058] Specifically, the float is a hollow shell made of plastic material.

[0059] In any of the above embodiments, the pressure plate 503 and the second sealing ring 505 are connected via a spring 506 .

[0060] When the float 502 blocks the second port 103 , the spring 506 is in a compressed state and applies a force in the longitudinal downward direction to the second sealing ring 505 .

[0061] In this embodiment, the pressure plate 503 is located on the upper surface of the floating rod 5, fixed on the central rod body 501, and can accept weighting operations from the outside; the second sealing ring 505 is installed on the side wall of the central rod body 501, and can slide along the central rod body 501 to adjust the position and maintain the seal; the spring 506 connects the pressure plate 503 and the second sealing ring 505, and is designed to transmit force and provide necessary elastic support, so as to maintain good sealing and flexibility under different conditions.

[0062] When the pressure plate 503 is pressurized by an external weight (such as a stone), the gravity is transmitted to the spring 506 through the pressure plate 503. The spring 506 is compressed and exerts a longitudinal downward force on the second sealing ring 505. The transmission of this force causes the second sealing ring 505 to move downward along the central rod 501 to adapt to the changing water level or pressure and maintain or enhance the sealing effect; when the float 502 moves downward due to the pressure of the wastewater and blocks the second port 103, the compressed state of the spring 506 helps the second sealing ring 505 to fit closely and seal the connection gap between the central rod 501 and the first port 102. This prevents water from continuing to flow through the port, thereby controlling the flow and treatment of wastewater. The presence of spring 506 provides the necessary elasticity and force adjustment, allowing the second sealing ring 505 to move freely as needed to adapt to changes in water pressure and other operating conditions; spring 506 ensures that even under dynamic conditions (such as water pressure changes, device movement, etc.), the sealing ring can respond quickly and effectively to maintain its sealing performance, providing a mechanical feedback mechanism that naturally adjusts the sealing pressure through the elastic element, reducing the risk of sealing failure.

[0063] In any of the above embodiments, the storage bin 4 further includes a first flange 403 mounted on the upper end of the light-transmitting tube 401 and a second flange 405 mounted on the lower end of the light-transmitting tube 401 .

[0064] The first flange 403 and the second flange 405 are fixedly assembled by a connecting rod 406 , and the connecting rod 406 is arranged outside the light-transmitting tube 401 along the circumference of the light-transmitting tube 401 .

[0065] In this embodiment, the first flange 403 is installed at the upper end of the light-transmitting tube 401, and is used to connect and fix the interface between the light-transmitting tube 401 and the storage bin 4 or other equipment. The second flange 405 is installed at the lower end of the light-transmitting tube 401, and is also used to connect and fix the interface between the light-transmitting tube 401 and the structure below. The connecting rod 406 is fixedly assembled between the first flange 403 and the second flange 405, and is arranged along the circumference of the light-transmitting tube 401. The setting of the connecting rod 406 not only enhances the structural stability of the entire light-transmitting tube 401, but also protects the light-transmitting tube 401 from external impact and pressure.

[0066] The connecting rod 406 ensures the physical stability and alignment of the light-transmitting tube 401 during operation by providing a solid connection between the first flange 403 and the second flange 405. This is essential to maintain the integrity and functionality of the light-transmitting tube 401, especially in the treatment of high-pressure or high-flow wastewater, helping the light-transmitting tube 401 to resist the mechanical stress and vibration that may be encountered during operation, and reducing the maintenance requirements caused by structural deformation or damage; the arrangement of the connecting rod 406 on the outside of the light-transmitting tube 401 provides an additional layer of protection for the light-transmitting tube 401 to prevent direct impact or accidental damage. When the light-transmitting tube 401 performs a photocatalytic or photochemical reaction, the presence of the connecting rod 406 ensures that the light-transmitting tube 401 can stably carry out the reaction process without external interference; through the combination of the flange and the connecting rod 406, the disassembly and maintenance of the light-transmitting tube 401 becomes more convenient and quick. The operator can easily access the interior of the light-transmitting tube 401 for cleaning or replacement without disassembling the entire storage bin 4 structure. The flange provides a reliable sealing and connection method, ensuring that the light-transmitting tube 401 can be quickly replaced or repaired when necessary without affecting the operation of the entire system.

[0067] In any of the above embodiments, the first flange 403 is fixedly assembled with the outer wall of the wastewater bin 1 , and the lower surface of the first flange 403 , the outer wall of the wastewater bin 1 forming the second port 103 and the inner wall of the light-transmitting tube 401 together form an annular groove.

[0068] The annular groove is connected to the third inner cavity 402 to reduce the waste in the third inner cavity 402 from entering the second inner cavity 201 again.

[0069] In this embodiment, the annular groove is formed by the lower surface of the first flange 403, the outer wall of the wastewater tank 1 forming the second port 103, and the inner wall of the light-transmitting tube 401. This structural design plays a key role in isolation and guidance in the wastewater treatment device.

[0070] The annular groove is designed to capture and isolate waste that may escape from the third inner cavity 402, and prevent such waste from flowing back into the second inner cavity 201. Through this physical barrier, the repeated inflow of treated waste can be effectively reduced. The annular groove acts as a buffer or sump to collect overflow or leakage in the third inner cavity 402, and by controlling the flow direction of these substances, ensure that they do not return to the core treatment area; by preventing pollutants from re-entering the treatment process, the effluent quality can be better controlled to ensure that environmental protection standards and requirements are met.

[0071] In any of the above embodiments, the storage bin 4 further includes an inverted cone-shaped cylinder 404 , which is fixedly assembled with the second flange 405 , and the interior of the inverted cone-shaped cylinder 404 is communicated with the third inner cavity 402 .

[0072] In this embodiment, the design of the inverted cone cylinder 404 utilizes the guiding effect of gravity and the cone structure to cause the treated pollutants to concentrate on the tip of the cylinder, thereby reducing the dispersion of pollutants in the storage bin 4, improving the collection efficiency, and reducing the residual pollutants; through the concentration and guidance of the inverted cone cylinder 404, more solids and heavier pollutants can be effectively separated, thereby further removing impurities before the water enters the next treatment stage.

[0073] In any of the above embodiments, the side wall of the connecting rod 406 is equipped with a slide plate 6 for longitudinal sliding, and a valve 7 is fixedly installed on the upper surface of the slide plate 6. The valve 7 is connected to the third inner cavity 402 through a hose. The valve 7 is used to drain water from the outside of the valve 7 box when the inspection personnel need to remove the storage bin 4, and before that, the float 502 is pressed to the bottom of the second inner cavity 201 by a heavy object to form a partition. By draining water, the wastewater on the top of the float 502 can form pressure on it, and after being separated from the wastewater bin 1, the waste inside the storage bin 4 can be cleaned.

[0074] In this embodiment, when the storage bin 4 needs to be removed for maintenance or cleaning, the float 502 is pressed to the bottom of the second inner cavity 201 by placing a heavy object on the valve 7. This operation forms a partition to prevent wastewater from mixing into or contaminating the cleaned area. Subsequently, water can be released from the storage bin 4 by operating the valve 7. The water release operation allows the float 502 to remain fixed during the cleaning process to prevent it from moving or floating. The operator can more safely separate the wastewater bin 1 and the storage bin 4, and perform internal cleaning and maintenance. During the cleaning process, dirt, sediment and other waste inside the storage bin 4 can be effectively removed to ensure the cleanliness and efficient operation of the equipment.

[0075] The valve 7 on the slide 6 is used to control the discharge of waste water, and the water is discharged through a hose. At the same time, a partition is formed by the cooperation of a weight and a float 502 to control the internal water pressure and water flow, so that the operator can dismantle and clean the storage bin 4 in a controlled environment.

[0076] In any of the above embodiments, the filter plate 3 is provided with a water hole 301 in the longitudinal direction, which communicates the first inner cavity 101 and the second inner cavity 201 .

[0077] In this embodiment, when wastewater flows from the first inner cavity 101 into the second inner cavity 201 through the water holes 301 of the filter plate 3, the suspended solids and larger particles in the water are physically intercepted, and only smaller particles and water molecules are allowed to pass through. This not only reduces the burden on subsequent treatment equipment, but also improves the overall treatment efficiency. The filtration process is carried out continuously, ensuring that the water flow from the first inner cavity 101 to the second inner cavity 201 is preliminarily treated, thereby providing a cleaner water source for the next step of deeper treatment.
