Description

Technical Field

[0001] This invention belongs to the field of energy dissipation dam technology, and specifically relates to an energy dissipation dam with pollutant removal capabilities and an energy dissipation and purification method. Background Technology

[0002] Currently, the traditional energy dissipation sedimentation basins commonly used at the inlet of artificial lakes employ a single method of energy dissipation: relying solely on head loss along the flow surface and retaining walls. During the overflow head descent, cavitation and erosion damage to the slab surface are easily caused, and significant pressure is exerted on the retaining walls. Stepped overflow energy dissipation dams are frequently used for bottom flow energy dissipation in large hydropower stations. They achieve energy dissipation through the lateral vortex formed by the water flow on the steps and the shear and momentum exchange between the water and the main flow. Furthermore, the aeration of the water flow on the dam surface enhances the energy dissipation effect while effectively preventing cavitation and erosion damage to the stepped surface and significantly increasing the dissolved oxygen (DO) concentration in the influent.

[0003] With rapid urbanization, large amounts of domestic and industrial wastewater containing high concentrations of recalcitrant organic pollutants from pharmaceuticals and personal care products are discharged into conventional wastewater treatment plants via municipal pipe networks, and then discharged into the aquatic environment after treatment. However, conventional wastewater treatment processes are inefficient at removing these pollutants, leading to a gradual increase in the types and concentrations of residual recalcitrant organic pollutants in aquatic environments (lakes, rivers, and reservoirs). These residual pollutants mainly include various antibiotics, environmental estrogens, and pesticide residues. These pollutants have long half-lives and slow biodegradation in aquatic environments, and at certain concentrations, they pose potential acute carcinogenic, teratogenic, and mutagenic hazards. Furthermore, after entering lakes, these pollutants gradually accumulate within the lake's food chain, severely impacting the lake's endogenous homeostasis.

[0004] Currently, conventional stepped overflow energy dissipation dams can only serve as drop-water energy dissipation devices, and their operation is dependent on the inflow rate at the inlet, making them unable to be autonomously controlled. Furthermore, they cannot effectively remove pollutants such as TP, TN, SS, and persistent organic pollutants from the inlet, significantly impacting aquatic plants and animals in downstream surface flow wetlands and other facilities. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, the purpose of this invention is to provide an energy dissipation dam with pollutant removal capabilities and an energy dissipation and purification method.

[0006] The technical solution adopted in this invention is as follows:

[0007] An energy-dissipating dam with pollutant removal capabilities includes a multi-stage energy-dissipating ladder. Each ladder has a box with an open top. A filtration energy-dissipating pool, inclined towards the upper energy-dissipating ladder, is connected within the box. The filtration energy-dissipating pool contains multiple segments of filter material with progressively smaller particle sizes, arranged from top to bottom. An ozone aeration unit is located at the lower end of the filtration energy-dissipating pool. The box also contains an inclined photocatalytic generator plate and a vacuum ultraviolet LED unit. The photocatalytic generator plate is located between the vacuum ultraviolet LED unit and the filtration energy-dissipating pool. The surface of the photocatalytic generator plate has photocatalytic material, and filter material is embedded within it. An outlet is located on the box, and a biological contactor is installed at the outlet. The biological contactor is connected to a blower aeration unit.

[0008] The present invention includes a filtration and energy dissipation tank connected to an inclined upper energy dissipation step within the tank. Water flowing down from the upper energy dissipation step enters the filtration and energy dissipation tank, passes through various sections of filter material, and then flows into a photocatalytic reaction plate. These multiple sections of filter material, with progressively decreasing particle sizes, filter the water sequentially. An ozone aeration unit at the lower end of the filtration and energy dissipation tank introduces ozone into the passing water for aeration. A vacuum ultraviolet LED unit is installed within the tank, and the surface of the photocatalytic reaction plate is covered with highly efficient photocatalytic material. TP, TN, and recalcitrant organic matter are removed from the water passing through the photocatalytic reaction plate. The water filtered by the photocatalytic reaction plate enters the lower part of the tank and then flows out through the outlet. A biological contactor removes organisms from the water, further improving water treatment capacity.

[0009] As a preferred embodiment of the present invention, the present invention further includes a control device, wherein the ozone aeration unit, the vacuum ultraviolet LED unit, and the blower aeration unit are electrically connected to the control device; the outlet is provided with a conductivity detector, a temperature sensor, a colorimetric detector, a pH value detector, and a dissolved oxygen detector, wherein the conductivity detector, the temperature sensor, the colorimetric detector, the pH value detector, and the dissolved oxygen detector are electrically connected to the control device.

[0010] Conductivity detectors, temperature sensors, color detectors, pH detectors, and dissolved oxygen detectors monitor the conductivity, temperature, color, pH, and dissolved oxygen at the outlet in real time and send the data to the control device. When the control device determines that the water quality is poor based on the conductivity, temperature, color, pH, and dissolved oxygen parameters, it increases the ozone aeration rate of the ozone aeration unit, increases the aeration rate of the blower aeration unit, and increases the intensity of the deep purple LED in the vacuum ultraviolet LED unit. When the control device determines that the water quality is good based on the conductivity, temperature, color, pH, and dissolved oxygen parameters, it decreases the ozone aeration rate of the ozone aeration unit, decreases the aeration rate of the blower aeration unit, and decreases the intensity of the deep purple LED in the vacuum ultraviolet LED unit.

[0011] In a preferred embodiment of the present invention, a vertical telescopic baffle is provided near the top of the upper step of the housing, and a horizontal telescopic baffle is provided at the top of the opening of the housing. The influent flow rate is monitored; when the influent flow rate is too high, the horizontal telescopic baffle retracts and the vertical telescopic baffle extends; when the influent flow rate is too low, the horizontal telescopic baffle extends and the vertical telescopic baffle retracts. Thus, the water flowing down from the upper energy dissipation steps is accurately guided to the upper end of the inclined filtration energy dissipation tank, ensuring that the water passes through each section of filter material sequentially.

[0012] In a preferred embodiment of the present invention, a tilting groove is hinged to the inner wall of the housing, and a slide rail is provided on the side wall of the filtration energy dissipation tank, the slide rail being fitted into the tilting groove; a telescopic rod is also installed on the housing, one end of the telescopic rod being connected to the filtration energy dissipation tank. The telescopic rod can push the filtration energy dissipation tank to tilt, thereby adjusting the tilt angle of the filtration energy dissipation tank and further controlling the water flow to accurately reach the uppermost part of the filtration energy dissipation tank. Since the slide rail on the filtration energy dissipation tank is fitted into the tilting groove hinged to the housing, no motion interference will occur when the telescopic rod pushes the filtration energy dissipation tank to tilt.

[0013] In a preferred embodiment of the present invention, the ozone aeration unit includes an oxidant mother liquor pressurizer disposed within a tank. The oxidant mother liquor pressurizer is connected to an ozone transport pipeline, and the other end of the ozone transport pipeline is connected to an ozone aeration rod, which is disposed at the lower end of the filtration and energy dissipation tank. The oxidant mother liquor pressurizer delivers ozone to the ozone aeration rod through the ozone transport pipeline, thereby providing stable ozone aeration to the water body.

[0014] As a preferred embodiment of the present invention, the aeration unit includes a blower disposed inside the housing, an air pipe connected to the air outlet of the blower, an aeration pipe connected to the other end of the air pipe, and the aeration pipe connected to the biological contactor.

[0015] As a preferred embodiment of the present invention, a sludge scraping mechanism is installed inside the box, the sludge scraping mechanism is disposed on the photocatalytic generator plate, and a sludge discharge port is provided on one side of the box.

[0016] In a preferred embodiment of the present invention, a guide groove is provided inside the housing, and the sludge scraping mechanism includes a moving device sleeved on the guide groove. The moving device has a built-in drive mechanism and a cleaning component connected to it. The cleaning component is disposed on the photocatalytic generator plate. The moving mechanism can drive the cleaning component to move on the surface of the photocatalytic generator plate, thereby scraping impurities on the surface of the photocatalytic generator plate towards the sludge discharge port, preventing clogging of the photocatalytic generator plate surface.

[0017] In a preferred embodiment of the present invention, a sludge discharge spiral is installed inside the housing, and the sludge discharge spiral is located at the bottom end of the photocatalytic generator plate. The sludge discharge spiral can assist in the discharge of impurities and prevent impurities from being unable to be scraped out of the sludge discharge port.

[0018] An energy dissipation and purification method includes the following steps:

[0019] S1: Monitor the conductivity, temperature, color, pH value, and dissolved oxygen at the outlet in real time, and send the data to the control device.

[0020] S2: When the control device determines that the water quality is poor based on the parameters in step S1, it increases the ozone aeration volume of the ozone aeration unit, increases the aeration volume of the blower aeration unit, and increases the deep purple LED intensity of the vacuum ultraviolet LED unit; when the control device determines that the water quality is good based on the parameters in step S1, it decreases the ozone aeration volume of the ozone aeration unit, decreases the aeration volume of the blower aeration unit, and decreases the deep purple LED intensity of the vacuum ultraviolet LED unit.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. In this invention, filter materials with progressively smaller particle sizes in each section of the filtration and energy dissipation tank sequentially filter water. An ozone aeration unit at the bottom of the filtration and energy dissipation tank introduces ozone into the passing water for aeration. A vacuum ultraviolet LED unit is installed inside the tank, and the surface of the photocatalytic generator plate has a highly efficient photocatalytic material, removing TP, TN, and recalcitrant organic matter from the water passing through the photocatalytic generator plate. A biological contactor removes organisms from the water, further improving water treatment capacity. Therefore, this invention can perform primary filtration, remove SS and homogeneous particle size pollutants, and remove TP, TN, and recalcitrant organic matter from the water.

[0023] 2. The present invention can adjust the horizontal and vertical telescopic baffles according to the inlet water flow, so that the water flowing down from the upper energy dissipation steps is accurately guided to the upper end of the inclined filtration energy dissipation tank, ensuring that the water can pass through each section of filter material in sequence.

[0024] 3. This invention can monitor the conductivity, temperature, color, pH value, and dissolved oxygen of each stage of the water outlet in real time, and can adjust the ozone aeration rate, aeration volume, and deep purple LED intensity according to the water quality.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the invention can be combined with each other.

[0036] like Figures 1 to 8As shown, the energy-dissipating dam with pollutant removal capability in this embodiment includes a multi-stage energy-dissipating ladder 1. A box 2 with an upper opening is provided on the energy-dissipating ladder 1. A filter energy-dissipating pool 3 inclined towards the upper energy-dissipating ladder 1 is connected inside the box 2. Multiple filter materials with progressively smaller particle sizes are arranged in the filter energy-dissipating pool 3 from top to bottom. An ozone aeration unit 4 is provided at the lower end of the filter energy-dissipating pool 3. An inclined photocatalytic generator plate 5 and a vacuum ultraviolet LED unit 6 are also provided inside the box 2. The photocatalytic generator plate 5 is located between the vacuum ultraviolet LED unit 6 and the filter energy-dissipating pool 3. The surface of the photocatalytic generator plate has photocatalytic material. The filter material is built into the photocatalytic generator plate 5. An outlet 71 is provided on the box 2. A biological contactor 72 is provided at the outlet 71. The biological contactor 72 is connected to a blower aeration unit 8.

[0037] The housing 2 of this invention is connected to a filtration and energy dissipation tank 3 inclined towards the upper energy dissipation step 1. Water flowing down from the upper energy dissipation step 1 flows into the filtration and energy dissipation tank 3, passes through various sections of filter material, and then flows into the photocatalytic reaction plate. The multi-section filter material with progressively decreasing particle size filters the water sequentially. An ozone aeration unit 4 at the lower end of the filtration and energy dissipation tank 3 introduces ozone into the passing water for aeration. A vacuum ultraviolet LED unit 6 is installed inside the housing 2. The surface of the photocatalytic generation plate 5 has a high-efficiency photocatalytic material, removing TP, TN, and recalcitrant organic matter from the water passing through the photocatalytic generation plate 5. The water filtered by the photocatalytic generation plate 5 enters the lower part of the housing 2 and then flows out from the outlet 71. A biological contactor 72 removes organisms from the water, further improving water treatment capacity.

[0038] The present invention also includes a control device, wherein the ozone aeration unit 4, the vacuum ultraviolet LED unit 6, and the blower aeration unit 8 are electrically connected to the control device; the outlet 71 is provided with a conductivity detector, a temperature sensor, a colorimetric detector, a pH value detector, and a dissolved oxygen detector, which are electrically connected to the control device.

[0039] A conductivity detector, temperature sensor, color detector, pH detector, and dissolved oxygen detector monitor the conductivity, temperature, color, pH, and dissolved oxygen of the outlet 71 in real time and send the data to the control device. When the control device determines that the water quality is poor based on the conductivity, temperature, color, pH, and dissolved oxygen parameters, it increases the ozone aeration rate of ozone aeration unit 4, increases the aeration rate of blower aeration unit 8, and increases the intensity of the deep purple LED in vacuum ultraviolet LED unit 6. When the control device determines that the water quality is good based on the conductivity, temperature, color, pH, and dissolved oxygen parameters, it decreases the ozone aeration rate of ozone aeration unit 4, decreases the aeration rate of blower aeration unit 8, and decreases the intensity of the deep purple LED in vacuum ultraviolet LED unit 6.

[0040] The interior of the filtration and energy dissipation tank 3 is filled with filter materials from top to bottom, including 5-8cm pebbles (10cm thick), 3-5cm pebbles (10cm thick), and 1-3cm volcanic rock (5cm thick). Adjacent sections of filter materials are separated by filter media baffles 32, which are permeable baffles with evenly distributed pores (1cm) on their surface. An outlet 33 is located at the lower end of the filtration and energy dissipation tank 3, through which water enters the photocatalytic generator plate 5. The filtration and energy dissipation tank 3 is inclined at 10°–20°, and the filtered water flows into the photocatalytic generator plate 5 through the outlet 33.

[0041] To adjust the direction and position of the water flow, a vertical telescopic baffle 21 is installed near the top of the upper step in the housing 2, and a horizontal telescopic baffle 22 is installed at the top of the opening in the housing 2. The inflow rate is monitored; when the inflow rate is too high, the horizontal telescopic baffle 22 retracts and the vertical telescopic baffle 21 extends; when the inflow rate is too low, the horizontal telescopic baffle 22 extends and the vertical telescopic baffle 21 retracts. Thus, the water flowing down from the upper energy dissipation step 1 is accurately guided to the upper end of the inclined filtration energy dissipation tank 3, ensuring that the water passes through each section of filter material sequentially. The vertical telescopic baffle 21 and the horizontal telescopic baffle 22 can be controlled by a cylinder.

[0042] To facilitate adjustment of the angle of the energy-dissipating filter 3, a tilting groove is hinged to the inner wall of the housing 2, and a slide rail 31 is provided on the side wall of the energy-dissipating filter 3, which is fitted into the tilting groove. A telescopic rod 23 is also installed on the housing 2, with one end connected to the energy-dissipating filter 3. The telescopic rod 23 can push the energy-dissipating filter 3 to tilt, thereby adjusting the tilt angle of the energy-dissipating filter 3 and further controlling the water flow to accurately reach the top of the energy-dissipating filter 3. Since the slide rail 31 on the energy-dissipating filter 3 is fitted into the tilting groove hinged to the housing 2, there will be no movement interference when the telescopic rod 23 pushes the energy-dissipating filter 3 to tilt. The telescopic rod 23 can be a cylinder. One end of the telescopic rod 23 is fixed to the housing 2, and the other end is fixed to the energy-dissipating filter 3, allowing adjustment of the tilt angle of the energy-dissipating filter 3. The initial angle is 10°, and it can be extended to 20° to adjust the filtration flow rate.

[0043] The vacuum ultraviolet LED unit 6 includes an arc-shaped reflective mirror 61 facing the photocatalytic generator plate 5. A support frame 62 is connected inside the reflective mirror 61, and an LED lamp post 63 is connected to the support frame 62. Several vacuum ultraviolet LED sheets 64 are mounted on the LED lamp post 63. A transparent cover for covering the LED lamp post 63 can be connected to the support frame 62 to protect the vacuum ultraviolet LED sheets 64.

[0044] The ozone aeration unit 4 includes an oxidant mother liquor pressurizer 41 installed inside the housing 2. The oxidant mother liquor pressurizer 41 is connected to an ozone transport pipe 42, and the other end of the ozone transport pipe 42 is connected to an ozone aeration rod 43, which is located at the lower end of the filtration and energy dissipation tank 3. The oxidant mother liquor pressurizer 41 delivers ozone to the ozone aeration rod 43 through the ozone transport pipe 42, thereby providing stable ozone aeration to the water body. The oxidant mother liquor in the oxidant mother liquor pressurizer 41 can be replaced with H2O2, PS, PMS, PI, KMnO4, etc.

[0045] The blower aeration unit 8 includes a blower 81 installed in the housing 2. The air outlet of the blower 81 is connected to an air pipe 82, and the other end of the air pipe 82 is connected to a blower aeration pipe 83. The blower aeration pipe 83 is connected to the biological contactor 72.

[0046] To ensure timely removal of impurities, a sludge scraping mechanism 9 is installed inside the housing 2, mounted on the photocatalytic generator plate 5. A sludge discharge port 24 is located on one side of the housing 2. A guide groove 26 is provided inside the housing 2. The sludge scraping mechanism 9 includes a moving device 91, which is fitted onto the guide groove 26. A drive mechanism is built into the moving device 91 to move it within the guide groove 26. A cleaning component 92 is connected to the moving device 91 and is mounted on the photocatalytic generator plate 5. The cleaning component 92 has extremely fine brush material on the side closest to the photocatalytic generator plate 5. One form of the drive mechanism involves a motor mounted on the moving device 91, with the motor's output connected to a reducer, and the reducer's output connected to a gear. A rack is installed within the guide groove 26, meshing with the gear. The photocatalytic generator plate 5 contains modified ceramic filter media (alumina ball filter media, silica filter media, etc.), with a surface covered with highly efficient photocatalytic material.

[0047] The moving mechanism drives the cleaning component 92 to move on the surface of the photocatalytic generator plate 5, thereby scraping impurities on the surface of the photocatalytic generator plate 5 towards the sludge discharge port 24, preventing clogging of the surface of the photocatalytic generator plate 5. A sludge discharge spiral 93 is installed inside the housing 2, located at the bottom end of the photocatalytic generator plate 5. The sludge discharge spiral 93 assists in the discharge of impurities, preventing impurities from being unable to be scraped out of the sludge discharge port 24. A U-shaped groove 94 is fitted around the sludge discharge spiral 93, with the U-shaped groove opening towards the side facing the photocatalytic generator plate 5. One end of the sludge discharge spiral 93 is connected to the sludge discharge drive mechanism.

[0048] An opening is provided at the lower end near the side of the lower energy dissipation step 1. An outflow tank 7 is installed inside the opening. A biological contactor 72 (with built-in biological contact filter media) is connected to a multi-stage dry aeration pipe 83 and installed at the bottom of the outflow tank 7. An outflow port 71 is located on the side of the outflow tank 7. A conductivity detector, temperature sensor, color detector, pH detector, and dissolved oxygen detector are built into the side of the outflow tank 7. All data are displayed in real time on the display screen of the control device, and adjustments are made in real time based on this data and the internal system.

[0049] The energy dissipation and purification method of this embodiment includes the following steps:

[0050] The conductivity, temperature, color, pH value, and dissolved oxygen of the outlet 71 are monitored in real time, and the data are sent to the control device. When the control device determines that the water quality is poor according to the parameters in step S1, it increases the ozone aeration rate of the ozone aeration unit 4, increases the aeration rate of the blower aeration unit 8, and increases the intensity of the deep purple LED of the vacuum ultraviolet LED unit 6. When the control device determines that the water quality is good according to the parameters in step S1, it decreases the ozone aeration rate of the ozone aeration unit 4, decreases the aeration rate of the blower aeration unit 8, and decreases the intensity of the deep purple LED of the vacuum ultraviolet LED unit 6.

[0051] The influent flow rate is monitored. When the influent flow rate is too high, the horizontal telescopic baffle 22 retracts and the vertical telescopic baffle 21 extends; when the influent flow rate is too low, the horizontal telescopic baffle 22 extends and the vertical telescopic baffle 21 retracts. Thus, the water flowing down from the upper energy dissipation step 1 is accurately guided to the upper end of the inclined filtration energy dissipation tank 3, ensuring that the water can pass through each section of filter material in sequence.

[0052] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
