Description

Technical Field

[0001] The invention relates to the technical field of water quality biological treatment, in particular to an oxygen-enriched multi-stage filtering biological floating island. Background Art

[0002] Ecological floating island, also known as artificial floating bed, ecological floating bed, etc. It is a kind of artificial floating island. It uses the principle of ecological engineering to degrade the COD, nitrogen and phosphorus content in the water for eutrophic water quality. It takes aquatic plants as the main body, applies the principle of soilless cultivation technology, uses polymer materials as carriers and matrices, applies the symbiotic relationship between species, and makes full use of the spatial niche and nutritional niche of the water body, so as to establish an efficient artificial ecosystem to reduce the pollution load in the water body. It can greatly improve the transparency of the water body, and at the same time, the water quality indicators are also effectively improved, especially it has a good inhibitory effect on algae. The most important effect of ecological floating island on water purification is to use the root system of plants to absorb eutrophic substances in the water, such as total phosphorus, ammonia nitrogen, organic matter, etc., so that the nutrients of the water body are transferred, and the water body odor and eutrophication caused by the closure or lack of self-circulation are reduced.

[0003] However, most biological floating islands now only filter water by planting green plants on the water. Although this can filter water, the filtration speed is slow, and sometimes the green plants on the water cannot grow well due to polluted water quality, resulting in a longer filtration time for the biological floating island and poor oxygen enrichment effect of the green plants on the water.

[0058] Among them, a water inlet 21 is arranged at the bottom end of the water guide frame 2, and the water inlet 21 is arranged at the water pumping port 013. A water baffle 23 is arranged at the top of the water guide frame 2. The water guide frame 2 is semi-cylindrical, and water retaining plates 22 are symmetrically arranged on both sides of the upper surface of the top of the water guide frame 2.

[0061] In addition, the spray rack 6 includes a placement seat 61, which is arranged on the upper surface of the floating island frame 01. A diverter plate 62 is arranged on the upper surface of the placement seat 61. Guide plates 63 are symmetrically connected on both sides of the diverter plate 62. The guide plates 63 are located above the second filter areas 012 on both sides.

The guide ports 621 facilitate the discharge of precipitation to both sides, and the guide plates 63 are inclined, which is more conducive to the flow of water.

[0062] In addition, an arc-shaped groove is provided on the upper surface of the guide plate 63, and drainage holes 631 are symmetrically opened on the groove wall of the arc-shaped groove of the guide plate 63. A drainage pipe 632 is provided on the bottom surface of the guide plate 63, and the drainage pipe 632 is connected to the drainage hole 631.

[0063] In addition, an opening 031 is opened on one side of the breeding net box 03, and a net wall on one side of the breeding net box 03 is set at the bottom end of the fixed rod 8. A partition door 82 is placed in the middle of the rod body of the fixed rod 8, and the partition door 82 is set at the opening 031. A positioning column 81 is set on the upper surface of the fixed rod 8. The partition door 82 can block the opening 031 to prevent fish from escaping.

[0064] In this embodiment, in the river management operation with poor water quality that needs to be filtered by oxygen enrichment, the biological floating island can be used to manage the water quality. First, the floating island frame 01 is set on the river that needs to be managed, and the position of the floating island frame 01 is fixed by towing ropes to keep it unchanged. The floating water tank 018 generates buoyancy, so that the floating island frame 01 is suspended on the water surface, and a plurality of filtering water-based green plants 02 are set in the first filtering area 011. The filtering water-based green plants 02 are selected from a type including but not limited to canna green plants, and these green plants are fixed with planting frames. These are all existing technologies and are well known to people in the field of biological floating islands. A small amount of filtering water-based green plants 02 are laid on the water surface of the second filtering area 012.

[0065] In addition, fish fry that purifies water quality, such as silver carp, which can purify water quality, are placed in the breeding net cage 03. In the early stage of the growth of the fish fry, the partition door 82 can be closed and the fish fry can be first kept in the breeding net cage 03.

[0066] When the biological floating island filters water, the driving mechanism 4 works, and the solar panel 42 is used to absorb solar energy and store electricity, and then power the motor 41 when it works. When the motor 41 is working, the output end of the motor 41 drives the second sprocket 52 assembled and connected thereto to rotate, so that the chain 51 mounted on the outside rotates synchronously, thereby driving the first sprocket 13 on the other side to rotate. When the first sprocket 13 is in a rotating state, the rotating shaft 11 set on the rotating frame 019 can rotate, thereby allowing the spiral disk 12 to rotate.

[0067] When the spiral disk 12 rotates, the spiral disk 12 cooperates with the water guide frame 2, and water is brought in by one end of the spiral disk 12, and the limiting plate 122 can play a certain limiting role, thereby ensuring that more water is scraped in during one rotation. As the spiral disk 12 rotates, the spiral disk 12 cooperates with the water guide frame 2 to carry the water upward, thereby transporting the water from the water pumping port 013 to the top of the water guide frame 2, and when the water passes through the top of the spiral disk 12, a part of the water will flow out through the through hole 121, and thus flow out from the first water outlet channel 24. Because the aperture of the through hole 121 is small, the flow rate is small, and only a small part of the water will flow out.

[0068] The water flowing out from the first water outlet channel 24 will flow to the water purification tank 7 below, and the first water outlet channel 24 is provided with an arc groove 241. The arc groove 241 makes it easier for the water to gather together and flow down. After the water flows out from the first water outlet channel 24, it flows into the water purification tank 7 below. The water purification tank 7 is a prior art, which contains activated carbon, filter cotton and other materials for filtering water quality. This water purification tank 7 is well known to people in the field of water purification. When the flowing water passes through the water purification tank 7, the water purification tank 7 can filter out some floating matter, thereby ensuring that the water dripping into the second filter area 012 has better quality, which is conducive to the better growth of the organisms in the second filter area 012.

[0069] The water discharged from the water purification tank 7 will drip onto the diverter plate 62. After the water flows onto the diverter protrusion 622, the diverter protrusion 622 can guide the water to the guide ports 621 on both sides more quickly due to its inclined surface. The guide ports 621 on both sides guide the water to the guide plate 63. Since the guide plate 63 is inclined, the water can flow downward quickly in the guide plate 63. During this process, the water will enter the drainage holes 631 on both sides and then be discharged from the drain pipe 632. The drain pipe 632 is detachable and can be cleaned regularly to prevent it from being blocked. Moreover, since the drain pipe 632 is forked, the water can still flow through the middle of the guide plate 63 even if it is partially blocked.

[0070] After the water is discharged from the drain pipe 632, it will drip onto the water surface of the second filter area 012. The two rows of guide plates 63 can continue to drip water. The continuous dripping increases the oxygen content in the second filter area 012, thereby making the water quality in the second filter area 012 more suitable for the growth of fry, playing the role of oxygen enrichment, purifying the water quality, and allowing the filtered water green plants 02 in the second filter area 012 and the first filter area 011 on one side to grow better.

[0071] When the water is transported to the top of the water guide frame 2 by the spiral disk 12, the water will be discharged from the second water outlet channel 25, and then the water will drip vertically onto the oxygen production unit 3 below, and the water will drip into the water storage box 321 below. The water in the water storage box 321 will slowly accumulate. When the water in the water storage box 321 accumulates to a certain amount, the water storage box 321 cooperates with the rotating disk 33 on the rotating support frame 31, so that when each water storage box 321 accumulates a certain amount of water, it will drive the rotating disk 33 to rotate on the rotating support frame 31, and cooperate with the water that continuously flows down from the water guide frame 2, so that the rotating disk 33 can rotate on the rotating support frame 31.

[0072] Whenever the water storage box 321 rotates, the water storage pipes 323 on both sides will be immersed in water when entering the drain port 014. After the water storage pipes 323 rotate out and come out of the drain port 014, the water storage pipes 323 are now full of water. Because the front tube body 3231 is facing upward at this time, the water is stored in the rear tube body 3232. Because the front tube body 3231 is facing upward, the water will not easily flow out of the water storage pipe 323. Once the water storage box 321 rotates to be located directly below the second water outlet channel 25, the front tube body 3231 is now facing downward, so that the water in the rear tube body 3232 can be discharged and drip onto the water surface. The water flow hitting the water surface has an oxygenation effect, because when the water flow hits the water surface, some water droplets will be knocked away or scattered, and when the water droplets are knocked away, they have full contact with the air, thereby increasing the oxygen content in the water. Moreover, the water flow hitting the water surface is continuous, so it will always have an oxygenation effect.

[0073] Because the water drops discharged from the second water outlet channel 25 originally drip onto the water surface continuously, the oxygen production effect produced by dripping onto the water surface is poor. After the water storage box 321 rotates, the water in the water storage pipe 323 can be discharged at one time, so that a large amount of water can be dropped at one time, which can increase the oxygen content of the water. In this way, the water in this area is better oxygen-enriched, which is more conducive to the growth of green plants 02 used for filtering water, so that the water quality can be effectively filtered, and the oxygen content in the water can be increased by the oxygen production unit 3, so that the water quality is better and fish organisms are better attracted, thereby achieving a good development of the ecological environment.

[0074] After the first step of filtration is performed by a large area of ​​filtering water green plants 02 in the first filtering area 011, combined with the filtering water green plants 02 in the second filtering area 012 and the fish fry in the breeding cage 03, this multi-stage filtration can make the filtration effect of the ecological floating island better.

[0075] In the present invention, multi-stage filtration is achieved by arranging a first filter area 011 and a second filter area 012 on the floating island frame 01, and water is transmitted to a high place by the transmission mechanism 1, and then discharged to the oxygen production unit 3, and the water accumulated in the water storage box 321 by dripping, and in conjunction with the rotating support frame 31, the dripping water can drive the rotating disk to rotate on the rotating support frame 31 so that the water storage pipe 323 can be filled with water, and at the same time, it can be discharged at a high place to form precipitation, so that a large number of water droplets can fall on the water surface at one time, thereby playing a role in increasing oxygen, so that the oxygen enrichment effect of the ecological floating island is better, and the water quality can be better filtered and purified.
