Description

Technical Field

The main equipment includes a front-end net-belt uniform water inlet pipe and a water guide pipe, a screening micro-nano bubble generator, an ion device, a bacteria-algae culture and reclamation tank, a multi-functional submersible pump, a small molecule cluster water generator, a magnetic device, and a porous drop water pipe for water outlet, etc.

[0002] The water body of the multi-functional submersible pump enters the small molecule cluster water generator and generates resonance with water by generating energy waves, turning the large molecule cluster water into small molecule cluster water. The water body enters the magnetic device and completes magnetic cutting in a small cross-sectional area region of strong magnetic cutting, magnetizing the water body into magnetized water. The solubility of water increases, and the permeability is further enhanced, enhancing the removal effect of pollutants in the water body. Background Art

[0003] With the acceleration of the industrialization process and the increase in population density, the problem of water pollution is becoming increasingly serious, and the requirements for water treatment technologies are also getting higher and higher. Especially after the introduction and implementation of the tail water discharge standards for the aquaculture industry, it has further attracted the attention and emphasis of the whole society. Traditional water treatment devices often have problems such as limited treatment effect, high energy consumption, and complex equipment. Therefore, it is particularly important to develop a high-efficiency, energy-saving, and multi-functional water treatment device. Summary of the Invention

[0004] The purpose of the present invention is to provide an aquaculture water quality recycling treatment system, which realizes the treatment and thorough purification of water bodies by integrating multiple treatment technologies, improves the water treatment efficiency, reduces energy consumption, and simplifies the operation process.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The water inlet pipe and the water guide pipe use double-wall corrugated pipes. Drill holes on the inner wall of the corrugated pipe. After drilling the small holes according to 3 times the cross-sectional area of the large pipe, cover the outer wall with a partition net. There is a distance of 15 mm between the outer wall and the inner wall. The outer wall can not only well support the partition net, but also the large area of the inner wall tunnel of the corrugated pipe allows water to pass through, reducing the flow rate outside the orifice, making the water inlet not easy to be blocked, and ensuring that the water can be smoothly sent from the water inlet section to the water outlet section;

[0007] The bacteria-algae culture and reclamation tank is used for on-site cultivation and reclamation of microbial strains and beneficial bacteria and algae. Cultivating and reclamation of microbial strains and beneficial bacteria and algae can not only improve the water quality, effectively prevent diseases, but also reduce the feed consumption by about 20%. Only by spending 10 yuan on cultivating and reclamation of microbial strains and beneficial bacteria and algae can save 180 yuan of feed money. Usually, chlorella is cultivated and reclaimed in summer, and diatoms are cultivated and reclaimed in winter;

[0008] The sieve nano bubble generator introduces air or oxygen into the micro-nano generator. The gas is adsorbed in the micropores through the molecular sieve, and the gas is separated and purified in the molecular sieve micropores. The gas molecules interact to form bubbles and are released from the molecular sieve to form nano bubble oxygenation.

[0009] The ion device is to bring ion gas generated from the ion device (ion concentration> 200 million / cm3) into the water, generate very dense and fine bubbles in the water, increase the viscosity of water and oxygen, and also increase the charge and polarity in the water, promote the precipitation of pollutants, and allow the charged ions in the water to adhere and precipitate. The polar molecules stimulate the reproduction of aquatic life and plants through ions, activate both microorganisms and water molecules, increase the biochemical rate by 20%-30%, quickly restore the food chain, and make the water clear to the bottom;

[0010] The magnetic device (8000=12000 Gauss) allows the water body to enter a high-strength magnetic cutting channel for magnetization, forming magnetic water that is then discharged through a multifunctional submersible aeration pump. The microbubbles with small molecular characteristics stay in the water body for 15 times longer and have strong penetrating power, which is conducive to penetrating the lower layer of sludge together with microorganisms and playing a role in digestion, allowing the sludge to be quickly reduced, directly replacing dredging, and more suitable for the reproduction and growth of fish;

[0011] The multifunctional submersible pump has a small head in its usage scenario, and can achieve a relatively large flow rate with low power. The multifunctional submersible pump uses a motor as a driving force and a pump body as a core part to achieve the pumping effect. After the submersible pump is installed with a water outlet pipe, it can be directly placed in the liquid and the liquid can be pumped to a designated location through the pump body, reducing the trouble of installation. Since the pump body adopts a closed structure, no noise and vibration will be generated during operation. On the basis of the Venturi principle after the horn pressurization port, it is improved to a more effective water-based negative pressure gas-liquid suction method, which is also convenient for daily input of medicines, microorganisms, bacteria and algae into the gas-liquid suction pipe.

[0012] The small molecular cluster water generator is connected to the outlet pipe of the multifunctional submersible pump. The inner wall of the outer pipe of the small molecular cluster water generator is covered with spiral energy tubes arranged side by side. The energy tubes are filled with energy materials such as graphene and rare earth. The far infrared rays generated by the energy tubes are superimposed by the spiral structure of the energy tubes, and resonate with the shock waves of the water flow. The high-frequency oscillation reaches more than 100 million times per second, which changes the structural state of the source water, shortens the water molecule chain, and changes the water molecule cluster water from large to small, promotes the comprehensive optimization of the physical and chemical properties of the source water, and converts it into small molecular cluster water. Both ends of the small molecular cluster water generator are provided with threads for easy connection. The outlet water of the multifunctional submersible pump is connected to the magnetic device through the conduit outlet of the small molecular generator, and finally discharged through the porous drop pipe.

[0013] For the described magnetic device, the effluent of the small molecule cluster water generator is connected to the magnetic device, allowing the water body to enter a narrow channel with a high-intensity magnetic field of 8000 - 12000 Gauss for magnetization to form magnetized water. The residence time of magnetic microbubbles in the water body increases by more than 15 times, and they have high solubility and strong penetration ability, which is conducive to penetrating deep into the sludge together with microorganisms to play a better digestion role, enabling the sludge to be rapidly reduced and directly replacing dredging. Small molecule cluster water and magnetized water are more suitable for the reproduction and growth of fish, making fish scales have stronger luster and shrimp shells harder. The physical and chemical properties of magnetized water have changed to a certain extent, which can more effectively provide the necessary nutrients and water for microorganisms, making the contact oxidation effect between microorganisms and fillers better. Magnetized water can affect the behavior of charged particles, microorganisms, and pollutants in sewage, causing physical or chemical changes, thereby achieving the purpose of purifying water quality. Specifically, magnetized water can change the charge state of pollutants, making them more easily adsorbed or precipitated. At the same time, it can also promote the metabolic activities of microorganisms, effectively remove pollutants, and accelerate the degradation process of organic matter;

[0015] Both ends of the small molecule cluster water generator are provided with screw threads for easy pipe connection. The effluent of the multi-functional submersible pump is connected to the described magnetic device through the conduit outlet of the small molecule generator and finally discharged through a porous drop pipe;

[0016] The specific steps are as follows:

[0017] S1: The sieve micro-nano bubble generator uses molecular sieve technology to introduce air or oxygen into the micro-nano generator. The gas is adsorbed in the micropores through the molecular sieve, and gas separation and purification are achieved within the micropores of the molecular sieve. Gas molecules interact with each other to form bubbles and are released from the molecular sieve, forming nano-bubble aeration. These microbubbles have a long residence time in water to achieve aeration. Compared with conventional nano-aeration equipment, the water and gas volume generated by the ultrasonic sieve nano-bubble generator under the same power exceed 10 times that of conventional nano-aeration equipment;

[0018] S2: The multi-functional submersible pump extracts water into the small molecule cluster water generator, where it undergoes superposition through the spiral structure of the energy tube and resonates with the shock wave of the water flow, shortening the water molecule chain and reducing the size of the water molecule cluster, promoting the overall optimization of the physical and chemical properties of the source water and transforming it into small molecule cluster water;

[0019] S3: The multi-functional submersible pump extracts a large flow of water into the magnetic device (8000 - 12000 Gauss), allowing the water to enter the high-strength magnetic cutting narrow channel for magnetization to form magnetized water;

[0020] S4: When discharging from the small molecule cluster water generator and the magnetic device, the water enters the porous pipe for dispersed dropwise discharge. The 300w large flow pump in the fish pond or water area extracts the bottom water upwards and also enters the porous pipe for dispersed dropwise discharge on the floating parts, causing the water body to produce surging and oxygenation and realizing the full replacement of the upper and lower layers of the water body;

[0021] Further, the pump body of the multi-functional submersible pump is 550mm long, 230mm in diameter, uses a 220V or 380V power supply, has a power of 0.5kw, and a flow rate of 100m3 / h, achieving a small power and a large flow rate.

[0022] Further, the external dimensions of the sieve nano-bubble generator are: 600mm long, 430mm wide, and 550mm high, causing the water to generate micro-nano bubbles.

[0023] Further, the external dimensions of the small molecule cluster generator are: 443mm long and 75 or 110mm in diameter. The effective length of the internal spiral energy tube of the small molecule cluster generator is 320mm, and the energy tube diameter is 12mm. The water flows through the specially designed device at a certain speed to generate energy waves and resonate with the molecular cluster water in the water, turning the large molecular cluster water into small molecular cluster water.

[0024] Further, the external dimensions of the magnetic device are: 620mm long, and the water passing shape is 150×150mm. The water body enters the high-strength magnetic cutting narrow channel through the magnetic device for magnetization to form magnetized water, increasing the solubility and improving the penetration power, which is beneficial to penetrate the sludge layer together with microorganisms and play a digestion role, enabling the sludge to be quickly reduced and directly replacing dredging.

[0025] The beneficial effects of the present invention:

[0026] (1) The present invention realizes a small power and a large flow rate by pumping water with a multi-functional submersible pump with a small lift. It uses the pore size of the micro-nano molecular sieve to selectively separate micro-bubbles from the gas phase, and these micro-bubbles stay in the water for a long time to achieve oxygenation. Compared with the conventional nano-aeration equipment, the water and gas volume generated by the ultrasonic sieve nano-bubble generator under the same power exceed 10 times that of the conventional nano-aeration equipment, achieving effective energy conservation and consumption reduction;

[0027] (2) The advantageous functions of the equipment of the present invention are manifested. The small-molecule cluster water generator makes the water body into small-molecule cluster water, and the magnetic equipment makes the water into magnetized water, increasing the solubility and permeability of the water body. At the same time, it can also promote the metabolic activities of microorganisms, remove pollutants, effectively remove sludge and replace dredging, realizing the efficient purification of the water body and significantly improving the water quality treatment effect;

[0028] (3) The magnetized water and charged ion bubbles generated by the magnetic equipment of the present invention can increase the residence time of microbubbles in the water body by more than 15 times, and have strong solubility and penetration ability, which is beneficial to penetrate deep into the sludge together with microorganisms and play a digestion role, enabling the sludge to be quickly reduced and directly replacing dredging. The magnetized water activates the enzymes, bacteria and microorganisms in the filler, showing a stronger role in promoting survival and reproduction, effectively improving the biochemical rate. The magnetized water treated by a strong magnetic field can more effectively provide the nutrients and water required by microorganisms, making the contact oxidation effect of microorganisms better. The magnetized water can affect the behavior of charged particles, microorganisms and pollutants in sewage, causing physical or chemical changes, changing the charge state of pollutants, making them more easily adsorbed or precipitated. At the same time, it can also promote the metabolic activities of microorganisms, effectively remove pollutants. The inclined tube sedimentation tank effectively separates the water body from dirt. Multiple treatment technologies realize the efficient purification of the water body and significantly improve the water quality treatment effect;

[0029] (4) Effectively remove pollutants at low cost, use the most energy-saving and cost-saving biological treatment method.

[0042] Example:

[0043] The multifunctional water treatment device includes a multifunctional submersible pump, a small molecular water generator, a magnetic device, an upper layer of nano bubble stones, a lower layer of suspended ball fillers and a filter material box, an inclined tube sedimentation tank and a rear end outlet pipe;

[0044] The invention is to use the aperture of micro-nano molecular sieve to selectively separate microbubbles from the gas phase. These microbubbles stay in the water for a long time to achieve oxygenation. Compared with conventional nano aeration equipment, the amount of water and gas produced by the ultrasonic sieving nano bubble generator under the same power is more than 10 times that of conventional nano aeration equipment.

[0045] The multifunctional submersible pump has a small head, so it has low power and large flow. The multifunctional submersible pump uses a motor as a driving force and a pump body as a core part to achieve the pumping effect. After the submersible pump is installed with a water outlet pipe, it can be directly placed in the liquid to pump the liquid to a designated location through the pump body, reducing the trouble of installation. Since the pump body adopts a closed structure, no noise and vibration will be generated during operation.

[0046] The small molecular cluster water generator is connected to the outlet pipe of the multifunctional submersible pump. The inner wall of the outer pipe of the small molecular cluster water generator is covered with spiral energy tubes arranged side by side. The energy tubes are filled with graphene and rare earth energy materials. The far infrared rays generated by the generator pass through the superposition of the spiral structure of the energy tubes and generate resonance waves with the shock waves of the water flow. The high-frequency oscillation reaches more than 100 million times per second, which changes the structural state of the source water, shortens the water molecule chain and changes the water molecule cluster water from large to small, promotes the comprehensive optimization of the physical and chemical properties of the source water, and converts it into small molecular cluster water. Both ends of the small molecular cluster water generator are provided with threads for easy connection. The outlet water of the multifunctional submersible pump is connected to the magnetic device through the conduit outlet of the small molecular generator.

[0047] The described magnetic device has the effluent of the small-molecule cluster water generator connected to it. The water body enters a high-intensity magnetic cutting channel for magnetization to form magnetized water. The residence time of the magnetic microbubbles in the water body increases by more than 15 times, and they have high solubility and strong penetration ability, which is conducive to penetrating deep into the sludge together with microorganisms and playing a digestion role, enabling the sludge to be rapidly reduced, directly replacing dredging. The small-molecule cluster water and magnetized water are more suitable for the reproduction and growth of fish, making the fish scales more lustrous and the shrimp shells harder. The physical and chemical properties of the magnetized water have changed to a certain extent, and it can more effectively provide the nutrients and water required by microorganisms, making the contact oxidation effect between microorganisms and the filler better. The magnetized water can affect the behavior of charged particles, microorganisms, and pollutants in the sewage, causing physical or chemical changes, thereby achieving the purpose of purifying water quality. Specifically, the magnetized water can change the charge state of pollutants, making them more easily adsorbed or precipitated. At the same time, it can also promote the metabolic activities of microorganisms, effectively remove pollutants, and accelerate the degradation process of organic matter;

[0048] The nano-bubble stone on the surface layer of the described suspended ball packing box generates oxygen for aeration in visible light. The suspended ball packing box plays the role of filtration and contact oxidation reaction. The selected packing and filter material have a large specific surface area and the characteristics of being loose and porous, which are easily utilized by microorganisms, can provide the necessary trace elements for the growth and reproduction of microorganisms, improve the biochemical rate, and effectively realize biodiversity at its activation sites;

[0049] The described inclined plate sedimentation tank utilizes the "shallow sedimentation" principle. The water flow and the inclined tubes allow the water to pass through in the direction of the designed angle, striving to shorten the particle sedimentation distance and increase the sedimentation area of the sedimentation tank, thereby shortening the sedimentation time and improving the treatment efficiency. The water to be treated and the sedimented sludge move and separate from each other in the shallow sedimentation layer. According to the water flow direction of their mutual movement, it can be divided into three different separation methods: co-current flow, counter-current flow, and lateral flow. After the substances sedimented by the inclined plates accumulate at the bottom of the tank, the clear water is pumped out from the upper part or side of the sedimentation tank for the continuity of the subsequent treatment process or the discharge of the clear water.

[0050] The specific steps are as follows:

[0051] S1: The screening nano-bubble generator selectively separates microbubbles from the gas phase using the pore size of the micro-nano molecular sieve. These microbubbles have a long residence time in water to achieve aeration. Compared with conventional nano-aeration equipment, under the same power, the amount of water and gas generated by the ultrasonic screening nano-bubble generator exceeds 10 times that of conventional nano-aeration equipment.

[0052] S2: The multifunctional submersible pump extracts water into the small-molecule cluster water generator, where it undergoes superposition through the spiral structure of the energy tube and generates resonance waves with the shock waves of the water flow, shortening the water molecule chains and reducing the size of the water molecule clusters, promoting the overall optimization of the physical and chemical properties of the source water and transforming it into small-molecule cluster water.

[0053] S3: The multifunctional submersible pump extracts a large flow of water into the magnetic device, allowing the water to enter the high-strength magnetic cutting channel for magnetization to form magnetized water.

[0054] S4: When discharging from the small-molecule cluster water generator and the magnetic device, the water enters the upper-layer nano-bubble stone for oxygenation, then reaches the lower-layer suspended ball fillers and filter materials for biological contact oxidation, and finally enters the outlet pipe after sedimentation in the inclined tube sedimentation tank to remove sludge.

[0055] Further, the pump body of the multifunctional submersible pump is 550 mm long, 230 mm in diameter, uses a 220V or 380V power supply, has a power of 0.5 kw, and a flow rate of 100 m3 / h, achieving a small power and a large flow rate.

[0056] Further, the external dimensions of the sieve nano-bubble generator are: 600 mm long, 430 mm wide, and 550 mm high, which can generate micro-ultrasonic cavitation micro-nano bubbles in water.

[0057] Further, the external dimensions of the small-molecule cluster generator are: 443 mm long, 75 mm in diameter, the effective length of the internal spiral energy tube is 300 mm, and the diameter of the energy tube is 12 mm. It allows water to flow through a specially designed device at a certain speed to generate energy waves and resonate with the water molecule clusters in the water, turning large-molecule cluster water into small-molecule cluster water.

[0058] Further, the external dimensions of the magnetic device are: 620 mm long, and the water-passing external shape is 150×150 mm. Through the magnetic device, the water enters the high-strength magnetic cutting channel for magnetization to form magnetized water, increasing the solubility and penetration power, which is beneficial to penetrate the lower layer of sludge together with microorganisms and play a digestion role, enabling the sludge to be quickly reduced, directly replacing dredging.

[0059] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
