Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and in particular to a device for purifying and repairing river and lake water. Background Art

[0002] The problem of lake water pollution is becoming increasingly serious, especially the difficulty in dealing with floating pollutants on the water surface (such as algae, oil films, plastic waste, etc.). It not only affects the beauty of the water area, but also affects the quality of the water area. In particular, it is more harmful to aquatic organisms. If not handled in time, it will affect the ecological balance.

[0003] Traditional purification devices mainly consider silt cleaning and algae cleaning. Their cleaning methods are relatively simple, and the purification effect is limited, making it difficult to achieve complete purification. The purified lake water cannot be recycled for further purification of the lake surface, but is directly discharged through the sluice gate, resulting in poor purification effect. Summary of the Invention

[0005] A river and lake water purification and restoration device comprises a gate, a primary purification unit arranged on the intercepting side of the gate, a secondary purification channel arranged beside the gate, a purification material room arranged on the gate body, and a terminal treatment system connecting the purification material room and the secondary purification channel. A hydraulically driven agitator is provided in the primary purification unit, whose water inlet corresponds to the lake surface, and whose water outlet is connected to the secondary purification channel. A filter body is provided in the secondary purification channel. A feeding device is provided in the purification material room. The water outlet end of the secondary purification channel enters the purification material room and is connected to the feeding device. The discharge port of the feeding device is connected to the primary purification unit and provides a purification material mixture to the hydraulically driven agitator. The terminal treatment system comprises a pipeline part, one end of the pipeline part is connected to the secondary purification channel and the feeding device, and the other end detours to the intercepting side of the gate and is equipped with a water outlet unit. The water outlet unit is located above the lake surface and forms a water curtain relative to the lake surface.

[0006] As a further preference, it also includes an intelligent control system, which includes a sensor detection array arranged on the lake surface. The sensor detection array is composed of a variety of water area detection sensors, which are installed on a connecting rod. One end of the connecting rod is hinged to the primary purification unit, and the other end floats the sensor on the lake surface. The intelligent control system also includes a control module for controlling the gate opening and a control module for controlling the release of the purification material mixture between materials.

[0007] As a further preference, the primary purification unit is a floating purification cylinder, and an interception net is installed at its water inlet, which controls the water level change through the gate opening, so that the primary purification unit automatically rises and falls with the water inlet on the interception side of the gate. Its top end is connected to the top of the gate body through a connecting rod structure, and its two sides are slidably connected to the interception side of the gate body.

[0008] As a further preference, one end of the water outlet of the primary purification unit is inclined downward toward the secondary purification channel, and an inclined seat is provided inside the primary purification unit, the inner end of the inclined seat is inclined toward the bottom direction of the hydraulically driven agitator and is provided with an inner inclined portion, and the outer end of the inclined seat is inclined toward the secondary purification channel and is provided with an outer inclined portion, and a triangular convection cavity is formed between the inner and outer inclined portions toward the bottom of the primary purification unit, and the inner inclined portion has an inner concave surface relative to the bottom side of the hydraulically driven agitator, and the inner concave surface is provided with a convection hole communicating with the convection cavity.

[0009] As a further preference, the secondary purification channel is vertically upward along the side of the gate, and is filled with at least two layers of filter bodies, the bottom layer is a quartz sand filter layer, the upper layer is an activated carbon adsorption layer, and a partition net is provided between the two. A vertical upward water storage channel is provided between the secondary purification channel and the side of the gate. The bottom end of the water storage channel is connected to the secondary purification channel, and the middle is connected to the water outlet of the primary purification unit. The thickness of the quartz sand filter layer is 0.5-1 meter, and there is a filter gap between each other. The thickness of the activated carbon adsorption layer is 0.3-0.8 meter. The middle activated carbon adsorption layer is divided into two layers on the left and right and distributed on both sides of the secondary purification channel, and a surging gap is formed between the two layers of activated carbon adsorption layers.

[0010] As a further preference, the top of the secondary purification channel is connected to a first release pipe, and the first release pipe is provided with at least three branches. The first branch enters the purification material room and is connected to the feeding device in the purification material room, the second branch directly detours to the interception side, the third branch enters the purification material room and is connected to the feeding device, and the other end is connected to the pipeline part of the terminal treatment system, and the third branch detours above the lake surface on the interception side of the gate.

[0014] The beneficial effects of the present invention compared to the prior art are:

[0015] When the level of floating pollutants is high, the control gate opening is reduced, causing the water level to rise to the primary purification unit. Lake surface water, carrying floating pollutants, is then drawn into the primary purification unit through the outlet and discharged into the secondary purification channel. Before being discharged into the secondary purification channel, the polluted water passes through a hydraulically driven agitator, which uses the kinetic energy of the water to rotate within the primary purification unit. Simultaneously, a discharge device in the purification material room directs the hydraulic agitator toward the primary purification unit to release a purification material mixture. The purified material mixture is stirred and dissolved in the polluted water by the hydraulic agitator, completing the primary purification process before flowing into the secondary purification channel. After secondary purification through the filters in the secondary purification channel, a portion of the purified water is injected into the purification material room and fed into the discharge device to dissolve the purified material mixture before being released into the primary purification unit. The remaining portion of the purified water passes through the feeding device, transferring a portion of the purified material mixture to a pipeline. From there, it is delivered to the outlet unit, where it falls to the lake surface through the purified material mixture. As it falls, this portion of purified water comes into contact with air, mixing with the oxygen in the air before being discharged onto the lake surface. The hydraulically driven agitator is driven by water energy, which not only dissolves the input purification material mixture quickly, but also reuses the purified lake water to dissolve the purification material mixture in advance and purify the lake surface in advance.

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-Figure 7 As shown: This embodiment provides a river and lake water purification and repair device, including a gate 10, a primary purification unit 20 arranged on the intercepting side of the gate 10, a secondary purification channel 30 arranged beside the gate 10, a purification material room 40 arranged on the gate body, and a terminal treatment system 50 connecting the purification material room 40 and the secondary purification channel 30. A hydraulically driven agitator 210 is provided in the primary purification unit 20, whose water inlet corresponds to the lake surface, and whose water outlet is connected to the secondary purification channel 30. A filter body is provided in the secondary purification channel 30, and the purification material room 40 is connected to the secondary purification channel 30. A feeding device is provided in the material room 40. The water outlet end of the secondary purification channel 30 enters the purification material room 40 and is connected to the feeding device. The discharge port of the feeding device is connected to the primary purification unit 20 and provides the purified material mixture to the hydraulically driven agitator 210. The terminal treatment system 50 includes a pipeline part 510. One end of the pipeline part 510 is connected to the secondary purification channel 30 and the feeding device, and the other end detours to the intercepting side of the gate 10 and is installed with a water outlet unit 520. The water outlet unit 520 is located above the paste surface and forms a water curtain relative to the lake surface.

[0026] In this embodiment, when the floating pollutants on the lake (river) surface are serious, the opening of the control gate 10 becomes smaller, the water level on the interception side rises to the primary purification unit 20, and the lake surface water carrying the floating pollutants (collectively referred to as polluted water for ease of description) enters the primary purification unit 20 from the water inlet, and then is discharged into the secondary purification channel 30 from the water outlet. Before being discharged into the secondary purification channel 30, the polluted water passes through the hydraulically driven agitator 210, and the kinetic energy of the water is used to drive the hydraulically driven agitator 210 to rotate in the primary purification unit 20. At the same time, the discharge equipment in the purification material room 40 is aligned with the hydraulically driven agitator 210 to release the purification material mixture into the primary purification unit 20, and the purification material mixture is driven by the hydraulically driven agitator 210. The dynamic agitator 210 stirs and dissolves the contaminated water, so that the contaminated water completes the first-level purification and flows to the secondary purification channel 30. A part of the purified water obtained after the secondary purification by the filter body in the secondary purification channel 30 enters the purification material room 40 and is used to be injected into the discharge equipment to dissolve the purified material mixture in advance before it is added to the primary purification unit 20. The other part of the purified water is transported to the pipeline part 510 through the feeding equipment, and is sent to the water outlet unit 520 by the pipeline part 510. It falls to the lake surface through the purified material mixture. This part of the purified water will come into contact with the air when it falls, mix the oxygen in the air with the purified material mixture, and then be discharged to the lake surface.

[0027] In this embodiment, the hydraulically driven agitator 210 is driven by water energy, which not only allows the input purification material mixture to dissolve quickly, but also reuses the purified lake water to dissolve the purification material mixture in advance and purify the lake surface in advance.

[0028] In another embodiment, the present invention also includes an intelligent control system 60, which controls the feeding equipment and controls the third-party loading equipment to feed the feeding equipment. The intelligent control system 60 includes a sensor detection array arranged on the lake surface. The sensor detection array is composed of a variety of water area detection sensors 610, which are installed on a connecting rod 611. One end of the connecting rod 611 is hinged to the primary purification unit 20, and the other end floats the sensor 610 on the lake surface. The intelligent control system 60 also includes a control module for controlling the opening of the gate 10, and a control module for controlling the feeding of the purification material mixture between materials.

[0029] In this embodiment, a variety of water area detection sensors 610 are similar to suspended matter sensors, pollution concentration sensors, oil pollution sensors, and ammonia nitrogen and nitrate sensors used for aquaculture water area detection. A universal joint is set on the primary purification unit 20, and one end of the connecting rod 611 is hinged on the universal joint. These sensors are installed on the other end of these connecting rods 611 and float on the lake surface through a float to implement water quality detection. The detection signal is fed back to the matching detection module on the controller, which controls the gate 10 to automatically reduce the opening. As the water discharge from the gate decreases and the water level rises, the lake surface rises to the limit position with the primary purification unit 20, and the sewage on the lake surface automatically enters the primary purification unit 20. The water energy is used to drive the hydraulic drive agitator 210 to rotate automatically. At the same time, the controller in the intelligent control system 60 controls the feeding equipment to mix the materials and automatically discharge them to the primary purification unit 20 through the flexible discharge pipe. After a period of purification, when the water quality is detected to meet the standards by each sensor, the intelligent control system 60 controls the above-mentioned electrical components to cut off power to achieve automation.

[0030] In another embodiment, the primary purification unit 20 is a floating purification cylinder, and an interception net is installed at its water inlet, which controls the water level change through the opening of the gate 10, so that the primary purification unit 20 and the water inlet automatically rise and fall according to the water level change. Its top is connected to the top of the gate body through a connecting rod structure, and its two sides are slidably connected to the interception side of the gate body. The sliding method is a roller with a track, but a limit is provided above the sliding position. When the primary purification unit 20 rises to the limit due to the water level change, it stops rising, and the sewage enters the primary purification unit 20. According to the rise and fall of the primary purification unit 20, each sensor is driven to float on the lake surface to detect the water quality.

[0031] In another embodiment, one end of the water outlet of the primary purification unit 20 is inclined downward toward the secondary purification channel 30, and an inclined seat 220 is provided inside the primary purification unit 20. The inner end of the inclined seat 220 is inclined toward the bottom direction of the hydraulically driven agitator 210 and is provided with an inner inclined portion 2201. The outer end of the inclined seat 220 is inclined toward the secondary purification channel 30 and is provided with an outer inclined portion 2202. A triangular convection cavity 2203 is formed between the inner inclined portion 2201 and the outer inclined portion 2202 toward the bottom of the primary purification unit 20. The inner inclined portion 2201 has an inner concave surface 2204 relative to the bottom side of the hydraulically driven agitator 210, and the inner concave surface 2204 is provided with a convection hole 2205 communicating with the convection cavity 2203.

[0032] In this embodiment, before the sewage is discharged toward the water outlet along the inner cavity of the primary purification unit 20, it will be buffered and blocked by the inner oblique portion 2201. The sewage will be discharged at a reduced speed under the buffering and blocking of the inner oblique portion 2201. After the vortex action of the inner concave surface 2204, it will flow into the convection cavity 2203 through the convection hole 2205. After the vortex surges in the convection cavity 2203, it will be discharged in the opposite direction through the convection hole 2205. Finally, it will be discharged through the outer oblique portion 2202 and the water outlet. After the water flow is intervened by the speed-up method, the residence time of the floating objects near the hydraulically driven agitator 210 is prolonged, so that the time for the mixture to be stirred and dissolved by the hydraulically driven agitator 210 is prolonged, thereby improving the dissolution quality.

[0033] In another embodiment, the secondary purification channel 30 is vertically upward along the side of the gate 10, and is filled with at least two layers of filter bodies. The bottom layer is a quartz sand filter layer 310, and the upper layer is an activated carbon adsorption layer 320. A partition net is provided between the two. A vertically upward water storage channel 3010 is provided between the secondary purification channel 30 and the side of the gate 10. The bottom end of the water storage channel 3010 is connected to the secondary purification channel 30, and the middle is connected to the water outlet of the primary purification unit 20. The thickness of the quartz sand filter layer 310 is 0.5-1 meter, and a filter gap is left between each other. The thickness of the activated carbon adsorption layer 320 is 0.3-0.8 meter. The middle activated carbon adsorption layer 320 is divided into two layers on the left and right and distributed on both sides of the secondary purification channel 30, and a surging gap is formed between the two layers of activated carbon adsorption layers 320.

[0034] In this embodiment, after the sewage is purified at the first level by the primary purification unit 20, it first enters the water storage channel 3010. The water storage channel 3010 provides a buffer space for the water after the first level of purification. Then, through the connection relationship, it enters the secondary purification channel 30 from the bottom of the secondary purification channel 30. After the secondary filtration by the quartz sand filter layer 310 at the bottom of the secondary purification channel 30, it rises to the activated carbon adsorption layer 320, continues to rise along the surging gap, and during the rising process, it is purified at the third level by the left and right layers of activated carbon adsorption layers 320 to remove odor.

[0035] In another embodiment, the top of the secondary purification channel 30 is connected to a first release pipe 330, and the first release pipe 330 is provided with at least three branches. The first branch 340 enters the purification material room 40 and is connected to the feeding device in the purification material room 40. The second branch 350 is connected to the pipeline part 510 of the terminal processing system 50. The third branch 360 is bent in a circuitous manner on the lake surface on the interception side of the gate 10.

[0036] In this embodiment, the water obtained after the third stage of purification enters the first release pipe 330, a small part of which enters the feeding device through the first branch 340 to dissolve the purified material mixture in the cabin in advance, and most of it is directly discharged back to the lake surface through the second branch 350 to neutralize the sewage, while also accelerating the release speed of the secondary purification channel 30, providing a buffer space for the purified water to continue to rise. Another small part passes through the third branch 360, and after the circuitous effect of the third branch 360, it entrains part of the purified material mixture and oxygen in the air and falls to the lake surface on the intercepting side of the gate 10, so that the lake surface is purified in advance, thereby improving the purification efficiency.

[0037] In another embodiment, the water outlet unit 520 is a complete spray body with a shield, connected to a large number of atomizing nozzles via thin tubes. The pipeline portion 510 of the terminal treatment system 50 is also equipped with a high-pressure atomizing pump. The high-pressure atomizing pump pressurizes the purified water, which is then sprayed onto the lake surface in an atomized form by the water outlet unit 520. When this purified water is reused, it is sprayed onto the lake surface in an atomized form, reducing the spraying speed. This allows this purified water to have a longer contact time with oxygen in the air, allowing a larger portion of the oxygen to fall onto the lake surface, further improving the quality of the lake surface's pre-cleaning.

[0038] In another embodiment, a second release pipe 3011 is connected to the water storage channel 3010, with the outlet of the second release pipe 3011 routing back to the interception side of the gate 10. When the primary purified water in the water storage channel 3010 is discharged into the secondary purification channel 30, the flow rate is affected by the presence of a purifier within the secondary purification channel 30. Therefore, the water storage channel 301 is relatively high, providing a larger buffer space. Even if it cannot fully accommodate the primary purified water, excess water can be discharged back to the interception side through the second release pipe 3011, thereby preemptively purifying and neutralizing the sewage surface on the interception side.

[0039] It should be further explained that the feeding equipment mentioned in the present invention, such as a feeding machine or feeding pump, has a feed port connected to a feeding device in the prior art, and a discharge port equipped with a solenoid valve. A controller automatically starts the feeding equipment, feeds, and mixes the materials. After a timer is set, the solenoid valve automatically opens for discharge. The discharge port is connected to a pipeline portion 510 and a flexible discharge pipe through two discharge channels, respectively. A portion of the purified material mixture is fed into the pipeline portion 510 to pre-purify the lake surface, and another portion of the purified material mixture is fed into the primary purification unit 20 through a flexible discharge pipe (e.g., a flexible discharge pipe) for primary sewage purification. The purified material mixture is composed of a flocculant (polyaluminum chloride (PAC), polyacrylamide (PAM), an algaecide (sodium percarbonate), and a modified bentonite; an oil degrader (bioenzyme preparation), a pH adjuster (sodium bicarbonate), and an oxidant (hydrogen peroxide slow-release granules), all mixed in proportion before feeding the material to the feeding equipment.
