Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to an open wastewater treatment system. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Existing wastewater treatment channel systems are mostly open-type structures, with the beam directly irradiating the water body. Although this approach results in low beam loss, the uniformity of irradiation cannot be guaranteed due to factors such as unstable water flow cross-sections and uncontrollable flow rates as the water passes through the irradiation area. Multiple irradiations or increased irradiation durations are required to ensure the treatment effect, leading to low wastewater treatment efficiency and unreliable treatment results. Furthermore, because the irradiation dose received by the wastewater body is inaccurate, the total dose received cannot be reasonably calculated and statistically analyzed. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an open sewage treatment system that controls the flow rate and velocity of sewage by improving the flow channel, thereby improving the sewage treatment effect and achieving accurate measurement of the amount of treated sewage.

[0005] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0006] An open-type wastewater treatment system includes a water tank, with an inlet and an outlet on both sides of the water tank; a designated area within the water tank is an irradiation zone, and an adjustment mechanism is provided between the inlet and the irradiation zone;

[0007] By adding an adjustment device in front of the irradiation area, the water flows through the gap between the adjustment mechanism and the bottom of the water tank into the irradiation area, which can effectively control the flow rate and thickness of the irradiated water, thus effectively improving the efficiency and effect of irradiation treatment.

[0008] In some embodiments, the adjustment mechanism includes an inclined portion and a horizontal portion arranged along the water flow direction, the angle between the inclined portion and the horizontal portion being an obtuse angle and pointing upwards; the side edge of the adjustment mechanism is sealed to the side wall of the water tank.

[0009] In some embodiments, the adjustment mechanism is provided with a lifting adjustment component connected to the horizontal part for adjusting the distance between the horizontal part and the bottom surface of the water tank, and the adjustment end of the lifting adjustment component is located outside the water tank.

[0010] By setting up a lifting and adjusting component, the gap between the horizontal part and the bottom of the water tank can be adjusted, which can adapt to different irradiation doses required for water bodies with different levels of pollution. If the pollution level is high, the gap can be appropriately reduced, and if the pollution level is low, the gap can be appropriately increased.

[0011] In some embodiments, a water throttling device is provided between the irradiation area and the outlet; the water throttling device includes multiple parallel throttling plates, each throttling plate having one side connected to a rod, each rod extending upward through the water tank and connected to a throttling adjustment mechanism, the adjustment end of the throttling adjustment mechanism being located outside the water tank for adjusting the rotation angle of the multiple rods; the bottom of each throttling plate is in contact with the bottom surface of the water tank.

[0012] A water throttling device is installed after the irradiation area to further ensure that the water flow cross section within the irradiation area is stable and the flow rate is controllable. Furthermore, by adjusting the distance between the horizontal plane of the adjustment mechanism and the bottom surface of the water tank, as well as the angle of multiple throttling plates, the thickness and flow velocity of the water body cross section within the irradiation area can be effectively controlled, so that the water body can meet the target requirements with only one irradiation.

[0013] In some embodiments, the throttling adjustment mechanism includes an operating platform disposed on the upper surface of the water tank and an operating plate disposed on the operating platform. One side of the operating plate is rotatably connected to one end of a plurality of connecting members via multiple connecting rods, and the other end of the plurality of connecting members is rotatably connected to a plurality of rods. The above-described throttling adjustment mechanism realizes a throttling plate angle adjustment method that is convenient for user operation.

[0014] In some embodiments, the throttling adjustment mechanism further includes a base plate and a pressure plate for clamping the operating plate. The base plate is fixed to the operating platform, and the pressure plate is provided with one or more adjustable fasteners for fixing the operating plate. Both ends of the base plate and the pressure plate are respectively fixedly connected to the operating platform. This structure provides a limiting function for the throttling adjustment mechanism, facilitating user operation and preventing water flow instability issues caused by excessively high water flow velocity leading to an increased switching angle.

[0015] In some embodiments, an entrance maze structure is provided between the water inlet and the adjustment mechanism. The entrance maze structure includes a first buffer structure and a second buffer structure. The first buffer structure has an inverted L-shaped cross-section, with one end connected to the bottom surface of the water tank and the other end facing the water inlet and higher than the inlet. The second buffer structure includes a horizontal plane and two vertical planes, surrounding the first buffer structure from above. The side edges of both the first and second buffer structures are sealed to the side walls of the water tank. By adding an entrance maze structure at the water inlet, effective buffering of the incoming water can be achieved, allowing wastewater to flow smoothly into the next area, ensuring a stable and controllable water flow throughout the water tank.

[0016] In some embodiments, a housing is provided below the water tank, and the housing is divided into an adjacent first water tank and a second water tank. The first water tank is connected to the inlet via a pipe, and the second water tank is connected to the outlet. Arranging the water tank for wastewater treatment and the water tanks containing wastewater before and after treatment vertically effectively saves space.

[0017] In some embodiments, a flow meter is installed on the pipeline to measure the flow rate of sewage.

[0018] In some embodiments, the pipeline includes an inlet pipe extending into the first water tank and an outlet pipe extending into the water tank via an inlet. The outlet pipe includes at least two branch pipes, each of which is equipped with a flow meter. By providing multiple outlet pipes, the uniformity of wastewater inflow is ensured.

[0019] In some embodiments, the system further includes a control device connected to both the irradiation equipment and the flow meter, for controlling the irradiation equipment and receiving data from the flow meter. This enables accurate measurement of the wastewater treatment volume. Attached Figure Description

Detailed Implementation

[0029] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0032] This embodiment discloses an open-type wastewater treatment system, such as Figure 1 As shown, it includes a housing 1, a pipe 2, a water tank 3, and a water outlet throttling device 5.

[0033] The container 1 is divided into an adjacent first water tank and a second water tank, which are used to hold sewage and irradiated water, respectively.

[0034] The water tank 3, used for wastewater treatment, is located above the tank body 1. A designated area within the water tank 3 is an irradiation zone for treating the wastewater. By arranging the tanks containing wastewater and the treated water adjacent to each other, and placing the wastewater treatment device above the water tank, space can be utilized more effectively.

[0035] like Figure 2 As shown, the pipeline 2 is used to transport sewage from the first water tank to the water tank 3, including an inlet pipe 2-1 extending into the first water tank and an outlet pipe 2-2 extending into the water tank 3. A water pump 7 is provided in the first water tank, and solenoid valves are provided on both the inlet pipe 2-1 and the outlet pipe 2-2.

[0036] Flow meters 2-3 are installed on the pipeline. In some embodiments, in order to make the sewage inflow more uniform and improve the accuracy of sewage flow statistics, the outlet pipeline includes at least two branch pipelines, and each branch pipeline is equipped with a flow meter 2-3 for measuring the flow of sewage flowing through the branch pipeline, thereby facilitating the calculation of the total treatment capacity of the sewage treatment device.

[0037] To ensure the stability of the water flow cross-section when wastewater passes through the irradiation area, in some embodiments of the present invention, an entrance labyrinth structure 8 is provided inside the water tank 3 between the pipe 2 and the irradiation area to control the direction and flow rate of the wastewater, thereby improving the stability of the water flow cross-section when the wastewater passes through the irradiation area. For example... Figure 3 As shown, the entrance maze structure 8 includes a first buffer structure 8-1 and a second buffer structure 8-2. The first buffer structure has an inverted L-shaped cross-section, with one end connected to the bottom surface of the water tank and the other end facing the water inlet and higher than the inlet. The second buffer structure includes a horizontal plane and two vertical planes, surrounding the first buffer structure from above. The side edges of both the first and second buffer structures are sealed to the side walls of the water tank.

[0038] With the above configuration, flow channels are formed between the first buffer structure 8-1 and the inner wall of the top surface of the water tank, as well as between the first buffer structure 8-1 and the second buffer structure 8-2. When sewage from the pipeline flows into the water tank, the first buffer structure 8-1 blocks the sewage. As the amount of sewage entering increases, the water surface successively overflows the first buffer structure 8-1 and the second buffer structure 8-2, flowing into the water tank from the two flow channels. That is, the sewage is diverted while the direction of water flow is changed, thereby buffering the water flowing out of the pipeline, allowing the sewage to overflow the opening and flow smoothly into the next area, making the water flow in the entire water tank stable and controllable.

[0039] Specifically, the first buffer structure 8-1 includes a first horizontal surface 8-2-1 and a first vertical surface 8-2-2 connected to each other. The first vertical surface 8-2-2 is connected to the lower surface of the water tank. The first horizontal surface 8-2-1 is parallel to the top surface of the water tank, and its end away from the first vertical surface 8-2-2 faces the direction of sewage inlet. The end of the outlet pipe of the pipeline 2 is located below the first horizontal surface 8-2-1 and is spaced a certain distance from the first vertical surface 8-2-2. The second buffer structure 8-2 includes a second horizontal plane 8-1-1 and two vertical planes, denoted as the second vertical plane 8-1-2 and the third vertical plane 8-1-3. The second horizontal plane 8-1-1 is located to the side of the first horizontal plane 8-2-1 and is parallel to the top surface of the water tank 3, and is spaced a certain distance from the inner wall of the top surface. The second vertical plane 8-1-2 and the third vertical plane 8-1-3 are connected to both ends of the second horizontal plane 8-1-1 and extend downwards, respectively located on both sides of the first buffer structure 8-1. The second vertical plane 8-1-2, facing the direction of sewage inlet, is spaced a certain distance from the side wall of the water tank, and its lower end is slightly higher than the plane where the first horizontal plane 8-2-1 is located; the third vertical plane 8-1-3 is spaced a certain distance from the first vertical plane 8-2-2.

[0040] If wastewater flows freely after entering the tank, the uniformity of its thickness cannot be guaranteed, thus affecting the wastewater treatment effect. Therefore, in some embodiments of the present invention, an adjustment mechanism 4 is provided between the entrance labyrinth structure 8 and the irradiation area. The distance between the adjustment mechanism and the bottom surface of the tank is adjustable, allowing water to flow under the adjustment mechanism to control the uniformity of the water thickness. Specifically, as... Figure 4As shown, the adjustment mechanism 4 includes an inclined portion 4-1 and a horizontal portion 4-2 arranged along the water flow direction. The angle between the inclined portion 4-1 and the horizontal portion 4-2 is an obtuse angle, and the angle points upwards. Both sides of the inclined portion 4-1 and the horizontal portion 4-2 are connected to the inner wall of the water tank 3, preventing water from overflowing from both sides. The inclined portion 4-1 is used to block and guide the water flow, causing it to flow slowly through the channel between the horizontal portion 4-2 and the bottom surface of the water tank, thereby controlling the thickness of the water flowing towards the irradiation area. The top of the inclined portion 4-1 may or may not be connected to the top of the water tank 3, as long as it can guide the sewage flowing from the front to below the horizontal portion 4-2.

[0041] In some embodiments, to make the water thickness adjustable, the adjustment mechanism 4 is further provided with a lifting adjustment component 4-4, which is connected to the horizontal part 4-2 and used to adjust the distance between the horizontal part 4-2 and the bottom surface of the water tank 3. The adjustment end of the lifting adjustment component is located outside the water tank. Those skilled in the art will understand that a certain gap needs to be left between the top of the inclined part 4-1 and the top of the water tank 3, and both sides of the inclined part and the horizontal part are in contact with the inner wall of the water tank 3, allowing it to move up and down along the inner wall of the water tank 3 without water overflowing. As a specific implementation, the lifting adjustment component adopts a nut-screw mechanism, including a screw and an adjusting nut. One end of the screw is connected to the horizontal part, and the other end extends upward through the upper surface of the water tank and is connected to the adjusting nut. In some embodiments, the adjustable range of the water thickness is 0.5mm-50mm.

[0042] In one specific implementation, the inclined and horizontal portions of the adjustment mechanism 4 are integrally formed, for example, using a single piece of stainless steel plate, which is bent to form the inclined and horizontal portions. The top of the inclined portion is positioned between the two inner sidewalls of the water tank via a fixing member 4-3. By operating the lifting adjustment assembly 4-4, the included angle between the horizontal portion 4-2 and the inclined portion 4-1 can be finely adjusted.

[0043] By setting adjustment mechanism 4, the water flow speed can be further controlled, making the water flow of sewage entering the irradiation area more stable, and the water height and flow rate controllable.

[0044] A certain range along the water outlet direction of the adjustment mechanism 4 is an irradiation area. Above the water tank, at a position corresponding to the irradiation area, an irradiation device is provided for irradiating the wastewater that has passed through the adjustment mechanism.

[0045] The water outlet throttling device 5 is used to divert the irradiated water and transfer it to the second water tank. For example... Figure 5 and Figure 6As shown, the water outlet throttling device 5 includes multiple parallel throttling plates 5-4. The bottom of each throttling plate 5-4 is in contact with the bottom surface of the water tank 3. One side of each throttling plate 5-4 is connected to a rod 5-9. Each rod 5-9 extends upward through the water tank and is connected to a throttling adjustment mechanism. The throttling adjustment mechanism drives the multiple rods 5-9 to rotate, thereby causing the multiple throttling plates 5-4 to rotate synchronously, forming multiple wedge-shaped channels. By controlling the size of the channels, the height and velocity of the water flow through the irradiation area can be controlled. Figure 7 The left and right sides show the initial state and a rotating state of the throttle plate 5-4, respectively.

[0046] In one specific implementation, the throttling adjustment mechanism includes an operating platform 5-1 mounted on the upper surface of the water tank and an operating plate 5-2 mounted on the operating platform 5-1. One side of the operating plate 5-2 is rotatably connected to one end of a plurality of connecting members 5-3 via multiple connecting rods 5-8, and the other end of the plurality of connecting members 5-3 is rotatably connected to a plurality of rods 5-9. By pushing the operating plate 5-2 on the operating platform 5-1, the plurality of throttling plates 5-4 can be rotated synchronously.

[0047] For ease of operation, the edge of the operating plate 5-2 away from the connecting rod is bendable for easy gripping. In some embodiments, the throttling adjustment mechanism further includes a limiting mechanism, comprising a base plate 5-5 and a pressure plate 5-6 for clamping the operating plate 5-2. The base plate 5-5 is fixed to the operating platform 5-1, and the pressure plate 5-6 is provided with one or more fasteners 5-7, such as fastening nuts, adjustable valves, etc., for fixing the operating plate 5-2 after it is pushed. The two ends of the base plate 5-5 and the pressure plate 5-6 are respectively fixedly connected to the operating platform 5-1, and the distance between the two fixed positions is the movable area of ​​the operating plate 5-3. Those skilled in the art will understand that the maximum movable stroke of the operating plate 5-3 is related to the width of the water tank, the size and number of throttling plates, and can be designed specifically according to the specific situation.

[0048] By adjusting the tilt angle of the throttling plate, the size of the water outlet channel can be adjusted, thereby controlling the thickness of the water in the tank and ensuring that the thickness of the water in the channel is consistent.

[0049] Through the entrance maze structure 8, the adjustment mechanism 4, and the outlet throttling device 5, the flow rate and height of sewage inside the tank can be precisely controlled, thereby achieving accurate measurement of the flow rate of sewage receiving irradiation.

[0050] The bottom of the water tank is located downstream of the water outlet throttling device 5 and has an opening to allow the irradiated water to flow into the second water tank.

[0051] In addition, a support frame 6 is provided below the sewage treatment device to provide support for the sewage treatment device.

[0052] In order to statistically analyze the wastewater treatment volume and the received irradiation dose, the system also includes a control device connected to the irradiation equipment and the flow meter, respectively, for controlling the irradiation equipment and receiving data from the flow meter.

[0053] By adjusting the distance between the horizontal plane of the adjustment mechanism and the bottom surface of the water tank, as well as the angle of multiple throttling plates, the thickness and flow velocity of the water body section within the irradiation area can be effectively controlled, so that the water body can meet the target requirements with only one irradiation.

[0054] In the above embodiments, the system first transmits sewage to the water tank through multiple branch pipelines, ensuring the uniformity of the water entering the inlet. The buffering effect of the inlet labyrinth structure further enhances the stability of the water entering the tank. On this basis, the thickness of the water flowing into the irradiation area is controlled within a certain range by the adjustment mechanism. At the same time, the outlet throttling device controls the water flow channel of the water passing through the irradiation area, ensuring that the water flow cross section in the irradiation area is stable and the flow rate is controllable. The sewage can be treated in one irradiation, which improves the efficiency and effect of irradiation treatment, makes the irradiation dose controllable, and thus achieves accurate measurement of sewage treatment volume and received irradiation volume.

[0055] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
