Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water pollution treatment, in particular to a water pollution treatment device for blue-green algae. BACKGROUND

[0002] In some nutrient-rich water, some blue-green algae often breed in large quantities in summer, and form a layer of blue-green and smelly scum on the water surface, which is called "water bloom". Large-scale blue-green algae outbreak is called "green tide" (corresponding to the red tide in the ocean). Green tide causes water quality deterioration, and in severe cases, it can exhaust the oxygen in the water and cause the death of fish.

[0003] Currently, there are various methods for treating blue-green algae, among which direct physical algae removal mainly refers to mechanical removal. Mechanical algae removal is a mechanical method of removing algae from a lake. It is generally applied in blue-green algae enrichment areas (blue-green algae are concentrated in a certain area by wind direction and wind power, etc.), and fixed algae removal facilities and algae removal ships are used to circulate the water in the area to effectively remove the floating algae layer and create conditions for the implementation of chemical or biological algae removal measures. It can be used as an auxiliary measure. Currently, the algae removal ship generally uses a filter screen to fish the algae in the water body during travel, which has low processing efficiency and unsatisfactory water treatment effect.

One end of the hull 1 is provided with an installation groove 5, in which the cyanobacteria harvesting device 2 is installed and connected. The cyanobacteria harvesting device 2 is used to clean and harvest cyanobacteria from lakes or rivers. The cyanobacteria harvesting device 2 is connected to the flocculation machine 3 through an algae-water pipeline system. The flocculation machine 3 is used to add flocculants and other agents to the pumped cyanobacteria-laden water, while simultaneously mixing the agents evenly into the cyanobacteria-laden water. The flocculation machine 3 can be purchased commercially; specific finished models include JDWSDJ-90 and ECO-5. The flocculation machine 3 is fixedly connected to the hull 1. The algae-water separation device 4 is also fixedly connected to the hull 1. The algae-water separation device 4 is used to separate the flocculent cyanobacteria mixture in the water and temporarily store the cyanobacteria sludge. The flocculation machine 3 is connected to the algae-water separation device 4 through a delivery pipeline system.

[0027] In one embodiment of the present invention, during specific operation, the hull 1 is first controlled to slowly travel in the polluted water area. During the travel of the hull 1, the cyanobacteria in the water area are collected and pumped by the cyanobacteria harvesting device 2, and the cyanobacteria in the water area are transported to the flocculation machine device 3 through the algae water pipeline system. The flocculation machine device 3 mixes the cyanobacteria in the water and performs pre-sedimentation of the cyanobacteria in the water. Then, the cyanobacteria in the flocculation machine device 3 is transported to the algae water separation device 4 through the conveying pipeline system. The algae in the algae water separation device 4 is filtered and separated by the algae. After treatment, the resulting cyanobacteria mud temporary kitchen is placed in the algae water separation device 4, and the treated water is discharged back into the water area.

[0028] In one embodiment, the cyanobacteria harvesting device 2 includes a collection end 101, an adjusting plate 102, a rotating plate 103, an internal suction pipe 104, an external suction pipe 105, a water pump 106, and an adjusting hydraulic cylinder 107. One end of the adjusting plate 102 is fixedly connected to the collection end 101. A collection port 108 is provided on one side of the upper end of the collection end 101. A grid plate 109 is fixedly connected inside the collection port 108. The grid plate 109 can intercept larger debris on the water surface, such as branches, wood blocks, and plastic bottles. To prevent pipe blockage and malfunction of the water pump 106, rotating plates 103 are fixedly connected to both sides of the other end of the adjusting plate 102. A rotating shaft is fixedly connected to one side of the outer end of each rotating plate 103, and the rotating shaft is rotatably connected to one side of the edge within the mounting groove 5.

Several water pumps 106 are fixedly connected to the bottom. The output end of the water pump 106 is connected to the algae water pipeline system, and the input end of the water pump 106 is fixedly connected to an external suction pipe 105. The other end of the external suction pipe 105 is connected to a collection end 101. Several internal suction pipes 104 are installed inside the collection end 101. One end of each internal suction pipe 104 is connected to the external suction pipe 105. In specific operation, the adjusting rod 110 is first pushed to rotate around the rotating shaft by adjusting the hydraulic cylinder 107, thereby... The rotating plate 103 drives the adjusting plate 102 to rotate, and the adjusting plate 102 drives the collecting end 101 to move up and down, so that the collecting port 108 on one side of the collecting end 101 is on the water surface. The specific adjustment details include that the collecting port 108 is partially submerged below the water surface, so that the water containing algae enters the collecting end 101. Then, the water pump 106 is started, and the blue-green algae water in the collecting end 101 is first drawn into the external suction pipe 105 by the built-in suction pipe 104, and then sent into the algae water pipeline system after passing through the suction pump.

[0029] In one embodiment of the present invention, four water pumps 106 are provided, two of which are standby water pumps. When the active water pump fails, the standby water pumps can be activated to ensure the normal treatment of water pollution.

[0030] In one embodiment, the algae water pipeline system includes a branch water pipeline 6 and a water supply pipeline 7. The output end of the water pump 106 is connected to the branch water pipeline 6, and a water stop valve is fixedly connected to the pipeline between the branch water pipeline 6 and the water pump 106. The water supply pipeline 7 is fixedly connected to the middle of the branch water pipeline 6, and the other end of the water supply pipeline 7 is connected to the flocculant equipment 3.

[0031] In one embodiment, the conveying pipeline system includes a first water guide pipeline 8, a conveying water pump 9, and a second water guide pipeline 10. One end of the flocculation machine 3 is fixedly connected to the first water guide pipeline 8, the other end of the first water guide pipeline 8 is fixedly connected to the conveying water pump 9, one end of the conveying water pump 9 is fixedly connected to the second water guide pipeline 10, and the other end of the second water guide pipeline 10 is connected to the algae-water separation device 4.

[0032] In one embodiment, the algae-water separation device 4 includes an algae-water separation tank 201, a water guiding device 202, a filter conveyor belt 203, a drive roller 204, a filter disc 205, an internal plate 206, and an algae sludge shaking device 207. A drain pipe 208 is fixedly connected to the outer wall of the lower side of the algae-water separation tank 201, and a valve is fixedly connected to the drain pipe 208. Four sets of rectangularly distributed drive rollers 204 are rotatably connected inside the algae-water separation tank 201. The filter conveyor belt 203 surrounds the outside of the four sets of drive rollers 204, and the filter conveyor belt 203 is connected to the drive rollers 204. Water-blocking rubber strips 209 are fixedly connected to the outer edges of the filter conveyor belt 203. A water guiding device 202 is fixedly connected inside the algae-water separation box 201 on one side of the upper end of the filter conveyor belt 203. One end of the second water guiding pipe 10 enters and exits the algae-water separation box 201 and is connected to the water guiding device 202. An internal plate 206 is fixedly connected inside the algae-water separation box 201 between the drive rollers 204. Several support blocks 210 are fixedly connected to the upper end of the internal plate 206. A filter tray 205 is fixedly connected to the upper end of the support blocks 210. The filter tray 205 is arranged opposite to the filter conveyor belt 203 of the upper drive. The bottom cross-section of the filter tray 205 is V-shaped. The structure includes a drain pipe 211 fixedly connected to the center of the bottom of the filter tray 205. The other end of the drain pipe 211 passes through the inner plate 206 and exits through the outer wall of one side of the algae-water separation box 201. One end of the inner plate 206 is equipped with an algae sludge shaking device 207, which is in contact with the filter conveyor belt 203 on the opposite side. In use, the cyanobacteria-laden water is first transported to the water guiding device 202 through the conveying pipeline system. Then, the water guiding device 202 evenly spreads the cyanobacteria-laden water onto the upper-driven filter conveyor belt 203, where the water is filtered, trapping the cyanobacteria within the filter conveyor belt. The filtered water drips into the filter tray 205 and is discharged from the algae-water separation box 201 through the drain pipe 211 at the bottom of the filter tray 205. The filter conveyor belt 203 moves slowly under the drive of the transmission roller 204. The blue-green algae mud is moved to the side position along with the filter conveyor belt 203. The filter conveyor belt 203 is in a vertical state here. Under its own gravity, some of the blue-green algae mud is peeled off and falls to the bottom of the algae-water separation box 201 for storage. The blue-green algae mud remaining on the side filter conveyor belt 203 is shaken off by the algae mud shaking device 207.

[0033] In a further improvement of the present invention, a non-contact liquid level sensor is fixedly connected to the outer side wall of the algae-water separation tank 201 for detecting the amount of blue-green sludge stored inside the algae-water separation tank 201. When a certain amount of blue-green sludge is collected, the hull 1 returns to the dock and discharges the blue-green sludge through the sewage pipe 208, which facilitates the transfer and treatment of the blue-green sludge.

[0034] In one embodiment, a drive motor 301 is fixedly connected to one side of the upper end of the algae-water separation box 201. One end of one set of transmission rollers 204 at the upper end is connected to the drive motor 301. The other ends of the two sets of transmission rollers 204 at the upper end pass through the algae-water separation box 201 and are fixedly connected to a linkage sprocket 302. The two sets of linkage sprockets 302 are connected by chain transmission. In use, the drive motor 301 drives the opposite transmission rollers 204 to rotate. The other end of the transmission rollers 204 drives the other set of transmission rollers 204 to rotate through the linkage sprocket 302 and the chain. The transmission force of the two sets of transmission rollers 204 drives the filter conveyor belt 203 to drive relative to each other.

[0035] In one embodiment, the water guiding device 202 includes a water guiding tank 303, a buffer plate 304, and a water guiding pipe 305. One end of the water guiding tank 303 is fixedly connected to the second water guiding pipe 10. The buffer plate 304 is fixedly connected inside the water guiding tank 303. An overflow port 306 is provided at the upper end of the buffer plate 304. An inclined water guiding pipe 305 is fixedly connected to one side of the lower end of the water guiding tank 303. The other end of the water guiding pipe 305 is located above the upper transmission filter conveyor belt 203. In use, the second water guiding pipe 10 transports the blue-green algae water to the water guiding tank 303. Then, the buffer plate 304 intercepts and buffers the incoming water. As the water level rises, the blue-green algae water overflows to the other side of the buffer plate 304 through the overflow port 306. Then, the blue-green algae water is guided to the filter conveyor belt 203 through the water guiding pipe 305.

[0036] In one embodiment, the algae sludge shaking device 207 includes a top rod 401, a connecting plate 402, a guide rod 403, a sliding sleeve frame 404, a right-angle plate 405, a chute rail 406, a sliding block 407, a rotating shaft 408, a rotating disk 409, an operating motor 410, a T-shaped bracket 411, a blower 412, an air supply pipe 413, and a branch air pipe 414. A T-shaped bracket 411 is fixedly connected to the lower end of the built-in plate 206. An operating motor 410 is fixedly connected to one side of the upper end of the T-shaped bracket 411. A rotating disk 409 is fixedly connected to the rotating shaft of the operating motor 410. A rotating shaft 408 is fixedly connected to one edge of the upper end of the rotating disk 409. The rotating shaft 408 is rotatably connected to the lower end of the sliding block 407. The sliding block 407 is slidably connected within the chute rail 406. The chute rail 406 is fixedly connected to the right-angle plate 405. Several relatively parallel guide rods 403 are fixedly connected to one end of the right-angle plate 405. Several sliding sleeve frames 404 are respectively slidably connected to the guide rod 403. The sliding sleeve frames 404 are all fixedly connected to the lower end of the built-in plate 206. The other end of the guide rod 403 is fixedly connected to one side of the connecting plate 402. The other side of the connecting plate 402 is fixedly connected to the top rod 401. The top rod 401 is in contact with the filter conveyor belt 203 on the opposite side. When in use, the motor 410 is first operated to drive the rotating disk 409 to rotate. The rotating disk 409 drives the rotating shaft 408 to make a circular motion. At this time, the rotating shaft 408 drives the sliding block 407 to make a reciprocating linear motion along the slide rail 406. At the same time, the slide rail 406 drives the right angle plate 405 to make a reciprocating linear motion. The right angle plate 405 drives the connecting plate 402 and the top rod 401 to make a reciprocating linear motion through the guide rod 403. Thus, the top rod 401 repeatedly hits and strikes the filter conveyor belt 203 on the side, causing the residual blue-green sludge on the filter conveyor belt 203 to peel off.

[0037] An air chamber 415 is provided inside the top rod 401. An air blowing hole 416 communicating with the air chamber 415 is provided on the outer wall of one side of the top rod 401. The edges of the air blowing hole 416 are all chamfered. The air blowing hole 416 is positioned opposite the filter conveyor belt 203 on the opposite side. Several air guide grooves 417 communicating with the air chamber 415 are provided inside the connecting plate 402. The air guide grooves 417 have a fan-shaped structure. Several air guide pipes 418 are fixedly connected to the upper end of the connecting plate 402. One end of each air guide pipe 418 is connected to the air guide groove 417, and the other end of each air guide pipe 418 is connected to the air support. Pipe 414 is fixedly connected, and air supply pipe 413 is fixedly connected in the middle of air branch pipe 414. The other end of air supply pipe 413 is connected to blower 412. Blower 412 is fixedly connected to the other side of T-shaped bracket 411. When in use, blower 412 blows air into air supply pipe 413. Air supply pipe 413 sends air into air guide groove 417 through air branch pipe 414. Air is evenly distributed to air chamber 415 through air guide groove 417. Finally, air is blown into filter conveyor belt 203 through air blowing hole 416 to further remove residual blue-green sludge on filter conveyor belt 203.

[0038] In the specific operation of this invention, the frequency of the algae mud shaking device 207 hitting the filter conveyor belt 203 is 10-20 times / second, and the amplitude of each vibration of the filter conveyor belt 203 is 0.5-1.5cm.

[0039] In one embodiment, pressure rollers 419 are rotatably connected to both sides of the upper end of the filter tray 205. The upper ends of the pressure rollers 419 are in contact with the filter conveyor belt 203. Counterpressure rollers 420 are rotatably connected to both sides of the upper end of the pressure rollers 419. The counterpressure rollers 420 are rotatably connected inside the algae-water separation box 201, and the lower ends of the counterpressure rollers 420 are in contact with the filter conveyor belts 203 on both sides of the pressure rollers 419. The filter conveyor belts 203 are squeezed and connected between the pressure rollers 419 and the counterpressure rollers 420. In this invention, the pressure rollers 419 on both sides are... The pressure roller 420, in conjunction with the pressure roller 19, forms two symmetrical protrusions on the upper filter conveyor belt 203. The two sets of protrusions, together with the water-blocking rubber strip 209, form a water trough, which can prevent the blue-green algae water from flowing to the outside from one side of the filter conveyor belt 203, thereby improving the filtration effect on the blue-green algae water and reducing the water content of the filtered blue-green algae sludge.
