Description

Technical Field

[0001] The present invention relates to the technical field of wastewater purification and treatment, and in particular to a highly efficient aquaculture wastewater treatment facility and method. Background Art

[0002] The nitrogen and phosphorus-rich wastewater generated during the aquaculture process is discharged into rivers, lakes and other water bodies, which can easily cause eutrophication of the water bodies. At the same time, inside the breeding pond, when the concentration of ammonia nitrogen, nitrite nitrogen and other substances that continue to accumulate in the breeding water is too high, it will have a strong toxic effect on fish and shrimp, and even cause death. Therefore, the purification and recycling of aquaculture wastewater has become an important part of reducing water pollution and saving water resources in the aquaculture process, and the treatment of aquaculture wastewater has become a hot topic in current water environment governance research.

[0003] The existing aquaculture ponds have a relatively simple structure. During the aquaculture process, the ponds need to be cleaned regularly, otherwise the water quality will deteriorate, causing pollution to the aquaculture itself, leading to illness or death of the aquaculture objects. At present, aquaculture ponds are basically unable to handle aquaculture waste, and basically all aquaculture is static water, and large-scale water changes are impossible. In the middle and late stages of aquaculture, feces, leftover bait and other excrement accumulate in large quantities, causing water quality to deteriorate and harmful microorganisms to breed in large numbers. Environmental stress seriously affects the growth and survival of aquaculture objects, resulting in a decrease in the success rate of aquaculture and a great impact on the quality and safety of aquatic products.

[0004] The Korean invention patent with application number KR1020180138276 discloses a double-tube assembled biofilter with the same inlet and outlet pipes. The biofilter is a bioreactor with an L-shaped pipeline, which is formed on the baffle of the inner bottom surface of the aeration tank so that the filter medium can pass and stir to form an L-shaped pipeline. It can quickly select the pipeline without using the inlet and outlet pipes without being limited by the space of the aeration reactor, and has the technical advantage of fast assembly speed. However, in the prior art, when the biofilter uses microorganisms to treat and degrade wastewater, the microorganisms may block the water outlet, resulting in a low drainage rate. Summary of the invention

[0005] The object of the present invention is to provide a highly efficient aquaculture wastewater treatment facility and method which is easy to assemble, has high degradation capacity and is not prone to clogging.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: The invention discloses a high-efficiency treatment facility for aquaculture wastewater, comprising: a container storing microbial filtration medium, the container being connected with an inlet pipe and an outlet pipe, a partition being arranged above the inner bottom surface of the container, the partition being evenly provided with through holes, the output end of the inlet pipe being located above the partition and being provided with a nozzle, and the nozzle being movably connected with a cover body.

[0007] Preferably, a columnar distribution chamber is provided at the bottom end of the partition, a funnel-shaped discharge chamber is formed between the partition and the distribution chamber, a flow guide hole connected to the discharge chamber is provided around the distribution chamber, and the distribution chamber is connected to the outlet pipe. A certain amount of microbial filtration medium is introduced into the container, and the aquaculture wastewater is connected to the inlet pipe. The aquaculture wastewater can be discharged from the nozzle at the end of the inlet pipe to the top of the partition, and is evenly distributed in the container filled with microbial filtration medium under the action of the cover body. The amount of ammonia nitrogen in the aquaculture wastewater is reduced by microorganisms to purify the aquaculture wastewater. The purified water body enters the funnel-shaped discharge chamber through the through hole on the partition, and then reaches the inside of the distribution chamber through the flow guide hole, and is finally discharged from the outlet pipe; The funnel-shaped discharge chamber guides the clean water passing through the through hole downward and inward, which helps to increase the clean water discharge rate.

[0008] Preferably, the inlet pipe passes through the lower part of the distribution chamber in the horizontal direction and extends upward in the center of the distribution chamber, the outlet pipe is connected to the lower part of the distribution chamber, and the outlet pipe and the inlet pipe are arranged relative to each other. The portion of the inlet pipe extending upward in the distribution chamber cooperates with the distribution chamber to form an annular channel allowing the clean water to flow out, that is, the clean water flow entering the distribution chamber from different diversion holes can contact the outer tube wall of the inlet pipe, reducing the possibility of water blockage caused by the impact of multiple water flows on each other. At the same time, the clean water flow can cause vibration when it acts on the tube wall of the inlet pipe, which helps to promote the shaking off of pollutants attached to the inner tube wall of the inlet pipe, reduce the risk of pipeline blockage and increase the water flow rate; Since the inlet pipe has a vertical extension part, that is, the aquaculture wastewater is sprayed upward and outward from the nozzle, the water body can be disturbed to form the suspension of microorganisms above the partition, which is conducive to the degradation of aquaculture wastewater by microorganisms; The interlaced arrangement of the inlet pipe and the distribution chamber can minimize the area of ​​the pipes exposed to the inside and outside of the container, optimize the spatial layout, and make the inflow and discharge paths of the aquaculture wastewater not pass through too many channels, greatly improving the efficiency of wastewater treatment.

[0009] Preferably, the cover body covers the outside of the nozzle, there is a gap between the cover body and the nozzle, the side wall of the lower part of the cover body is evenly provided with flow grooves, the cover body can rotate relative to the nozzle, and blades are arranged around the cover body. The aquaculture wastewater sprayed from the nozzle contacts the inner wall of the cover body through the gap space, forming a water flow that diffuses to the bottom and the outside, increasing the diffusion range of the aquaculture wastewater above the partition, and increasing the contact range between the water body and the microorganisms, thereby improving the purification efficiency.

[0010] Preferably, the blades include inner blades and outer blades, the inner blades are fixed on the inner side of the cover, and the outer blades are fixed on the outer side of the cover. The aquaculture wastewater sprayed upward and outward by the nozzle is blocked by the cover and acts on the inner blades of the cover, thereby causing the cover to rotate. At the same time, the rotating cover can stir the aquaculture wastewater and microorganisms above the partition through its outer blades, preventing the microorganisms from being deposited on the end surface of the partition, promoting the homogenization of the microorganisms in the aquaculture wastewater, and improving the degradation rate of the aquaculture wastewater; During the rotation of the cover, the inner blades are carried to rotate outside the nozzle, and the vortex formed inside cleans the nozzle, reducing the possibility of pollutants or particles in the aquaculture wastewater clogging the nozzle, and improving the efficiency of the introduction and purification of aquaculture wastewater. During the rotation of the cover, the outer blades are carried to stir the aquaculture water and microorganisms and form a vortex. On the one hand, the vortex helps to clean the inner wall of the container above the partition, reducing the difficulty of cleaning. On the other hand, the vortex is guided downward by the funnel-shaped discharge chamber after passing through the through holes on the partition, forming a vortex concentrated downward, which helps to improve the sedimentation performance of solid components in the purified water body, that is, the solid components can be effectively removed in the biological filter tank, so that the water output from the outlet pipe does not contain large solid particles, thereby improving the cleanliness of wastewater treatment; The vortex can guide the water, causing the microorganisms or particles stuck in the through holes to leave, further ensuring the output efficiency of the purified water, and avoiding the continuous increase of water above the partition and difficulty in output, resulting in water overflow and polluting the environment.

[0011] Preferably, a ring is fixed to the inner bottom of the cover, and the ring is sleeved on the portion of the inlet pipe located above the partition. The arrangement of the ring can keep the cover outside the nozzle, so that there is a distance between the nozzle and the cover to ensure the normal output of the aquaculture wastewater, and at the same time ensure that the cover can rotate relative to the nozzle; Preferably, the upper end of the nozzle and the top end of the cover are both hemispherical, and the nozzle has spray holes that diverge in multiple directions. The nozzle with spray holes reduces the number of bubble dispersers installed in the container, and can fully realize the function of purifying aquaculture wastewater by suspending and stirring the microbial filtration medium, thereby reducing the energy consumption of aeration devices and saving costs.

[0012] Preferably, the through holes are slit holes in the form of elongated holes with a predetermined length, and the slit holes are arranged at equal intervals along the radial direction of the edge of the partition. The slit-shaped through holes can effectively block the microorganisms above the partition, ensure the number of microorganisms above the partition, and prevent the microorganisms from being discharged along with the purified water, resulting in a reduction in the purification efficiency of subsequent aquaculture wastewater.

[0013] Preferably, the distribution chamber has a lower flange on the outside, the discharge chamber has an upper flange that is tightly matched with the upper end of the lower flange, and a sealing gasket is provided between the lower flange and the upper flange. The sealing gasket is installed on the upper end surface of the lower flange, and then the upper flange of the discharge chamber is installed above the sealing gasket to form an installation connection between the discharge chamber and the distribution chamber. During use, the container is installed above the distribution chamber, and the sealing gasket is continuously compressed by the weight of the container, which ensures water tightness without the need to assemble sealing parts such as bolts, thereby reducing the manufacturing cost. After use, there is no need for tedious disassembly work, and only the water body needs to be completely discharged to reduce the overall weight of the container, and then the container is lifted to complete the rapid separation of the container and the distribution chamber, which speeds up the efficiency of installation and disassembly, and also improves the effect of disassembly, cleaning and maintenance of the entire equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the downward pressure assembly connection between the container, the distribution chamber and the discharge chamber is convenient for disassembly and cleaning, reducing the time cost; the annular channel formed by the distribution chamber and the inlet pipe can avoid water blockage, while reducing the risk of pipeline blockage and increasing the water flow rate; the cover body rotates under the impact of the water flow, forming the stirring of the water body, promoting the homogenization of the water body, and increasing the purification rate of aquaculture wastewater by microorganisms; the rotating blades stir the water body to form a vortex, and cooperate with the distribution chamber to promote solid sedimentation, improve the cleanliness of the water body, and realize the centralized collection of solids for easy treatment; the rotating inner leaves can form self-cleaning for the nozzle to avoid the clogging of the holes by particulate matter.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0019] See attached Figure 1 -Attached Figure 3 , a high-efficiency treatment facility for aquaculture wastewater, including: a container 1 storing a microbial filtration medium, the container 1 is connected to an inlet pipe 10 and an outlet pipe 11, a partition 2 is arranged above the inner bottom surface of the container 1, the partition 2 is evenly provided with through holes 20, the output end of the inlet pipe 10 is located above the partition 2 and is provided with a nozzle, and the nozzle is movably connected to a cover body 6.

[0020] A columnar distribution chamber is provided at the bottom end of the partition 2 , a funnel-shaped discharge chamber 4 is formed between the partition 2 and the distribution chamber, a flow guide hole connected to the discharge chamber 4 is arranged around the distribution chamber, and the distribution chamber is connected to the outlet pipe 11 .

[0021] It should be noted that the funnel-shaped discharge chamber 4 includes a conical sleeve with its small end facing downward, the top of the distribution chamber abuts against the bottom center of the partition 2, the upper edge of the conical sleeve is located at the outer edge of the lower end of the partition 2, and the bottom inner edge of the conical sleeve cooperates with the outer wall of the distribution chamber.

[0022] A certain amount of microbial filtration medium is introduced into the container 1, and the aquaculture wastewater is connected to the inlet pipe 10. The aquaculture wastewater can be discharged from the nozzle 5 at the end of the inlet pipe 10 to the top of the partition 2, and is evenly distributed in the container 1 filled with the microbial filtration medium under the action of the cover body 6. The amount of ammonia nitrogen in the aquaculture wastewater is reduced by microorganisms to purify the aquaculture wastewater. The purified water body successively enters the funnel-shaped discharge chamber 4 through the through hole 20 on the partition 2, and then reaches the inside of the distribution chamber through the guide hole 30, and finally is discharged from the outlet pipe 11; The funnel-shaped discharge chamber 4 guides the clean water passing through the through hole 20 downward and inward, which helps to increase the clean water discharge rate.

[0023] The inlet pipe 10 passes through the lower part of the distribution chamber in the horizontal direction and extends upward in the center of the distribution chamber. The outlet pipe 11 is connected to the lower part of the distribution chamber, and the outlet pipe 11 is arranged opposite to the inlet pipe 10. The portion of the inlet pipe 10 extending upward in the distribution chamber cooperates with the distribution chamber to form an annular channel allowing the clean water to flow out, that is, the clean water flow entering the distribution chamber from different guide holes 30 can contact the outer tube wall of the inlet pipe 10, reducing the possibility of water blockage caused by the impact of multiple water flows on each other. At the same time, the clean water flow can cause vibration when it acts on the tube wall of the inlet pipe 10, which helps to promote the shaking off of pollutants attached to the inner tube wall of the inlet pipe 10, reduce the risk of pipeline blockage and increase the water flow rate; Since the inlet pipe 10 has a vertically extending portion, that is, the aquaculture wastewater is sprayed upward and outward from the nozzle 5, the water body can be disturbed to form a suspension of microorganisms above the partition 2, which is conducive to the degradation of the aquaculture wastewater by microorganisms; The interlaced arrangement of the inlet pipe 10 and the distribution chamber can minimize the area of ​​the pipeline exposed to the inside and outside of the container 1, optimize the spatial layout, and make the inflow and discharge paths of the aquaculture wastewater not pass through too many channels, thereby greatly improving the efficiency of wastewater treatment.

[0024] See attached Figure 4 -Attached Figure 5 The cover body 6 covers the outside of the nozzle 5. There is a gap between the cover body 6 and the nozzle 5. The side wall at the lower part of the cover body 6 is evenly distributed with flow grooves 60. The cover body 6 can rotate relative to the nozzle 5. The cover body 6 is surrounded by blades 7.

[0025] The blades 7 include inner blades 70 and outer blades 71. The inner blades 70 are fixed on the inner side of the cover body 6, and the outer blades 71 are fixed on the outer side of the cover body 6. The aquaculture wastewater sprayed upward and outwardly by the nozzle 5 is blocked by the cover body 6 and acts on the inner blades 70 of the cover body 6, thereby causing the cover body 6 to rotate. At the same time, the rotating cover body 6 can stir the aquaculture wastewater and microorganisms above the partition 2 through the outer blades 71 on the outer side thereof, thereby preventing the microorganisms from being deposited on the upper end surface of the partition 2, promoting the homogenization of the microorganisms in the aquaculture wastewater, and improving the degradation rate of the aquaculture wastewater. During the rotation of the cover body 6, the inner blades 70 are carried to rotate outside the nozzle 5, and the vortex formed inside cleans the nozzle 5, reducing the possibility of pollutants or particles in the aquaculture wastewater clogging the nozzle 5, and improving the efficiency of the introduction and purification of the aquaculture wastewater. During the rotation of the cover body 6, the outer blades 71 are carried to stir the aquaculture water and microorganisms and form a vortex. On the one hand, the vortex helps to clean the inner wall of the container 1 above the partition 2, reducing the difficulty of cleaning. On the other hand, the vortex is guided downward by the funnel-shaped discharge chamber 4 after passing through the through hole 20 on the partition 2, forming a vortex concentrated downward, which helps to improve the sedimentation performance of solid components in the purified water body, that is, the solid components can be effectively removed in the biological filter, so that the water body output by the outlet pipe 11 does not contain large solid particles, thereby improving the cleanliness of wastewater treatment; The vortex can guide the water, causing the microorganisms or particles stuck in the through hole 20 to leave, further ensuring the output efficiency of the purified water, and avoiding the continuous increase of water above the partition 2 and difficulty in output, resulting in water overflow and polluting the environment.

[0026] A ring body 8 is fixed to the inner bottom of the cover body 6, and the ring body 8 is sleeved on the portion of the inlet pipe 10 located above the partition 2. The arrangement of the ring body 8 can keep the cover body 6 arranged outside the nozzle 5, so that there is a distance between the nozzle 5 and the cover body 6 to ensure the normal output of the aquaculture wastewater, and at the same time ensure that the cover body 6 can rotate relative to the nozzle 5; The ring body 8 is made of foam material and has buoyancy. The ring body 8 can rotate and slide on the outside of the part of the inlet pipe 10 located on the partition 2. When the inlet pipe 10 inputs aquaculture wastewater into the container 1, the inner wall of the cover body 6 receives the impact of the water at the top. At this time, the cover body 6 floats up and down relative to the nozzle 5 under the influence of the buoyancy of the bottom ring body 8. On the one hand, the cover body 6 slides longitudinally and carries the outer blades 71 to rotate, which promotes water disturbance, stirs the water at different height layers above the partition 2, promotes the exchange of the upper water body and the lower water body, improves the homogenization of the wastewater and microorganisms, and stabilizes the purification degree of the output water body. On the other hand, the ring body 8 that slides up and down can scrape off the pollutants, microorganisms and sediment attached to the outside of the nozzle 5, ensuring that the output of water from the nozzle 5 is not hindered, reducing the maintenance frequency and improving the stability of water treatment.

[0027] When the output rate of the inlet pipe 10 is low, the storage amount of aquaculture wastewater above the partition 2 is also low. At this time, the buoyancy of the ring body 8 is low, and the overall height of the cover body 6 moves down, causing the top of the inner wall of the cover body 6 to be blocked above the nozzle 5, that is, the water sprayed from the injection hole 50 acts more on the inner wall of the cover body 6, and the top of the inner wall of the cover body 6 is lifted to form friction with the nozzle 5. The friction reduces the rotation rate of the cover body 6, forming low-speed rotating stirring; when the output rate of the inlet pipe 10 is high, the storage amount of aquaculture wastewater above the partition 2 is also high. At this time, the buoyancy of the ring body 8 is high, and the overall height of the cover body 6 moves up, causing the top of the inner wall of the cover body 6 to have enough space between the nozzle 5 and the nozzle 5 and be filled with water. At this time, the top of the inner wall of the cover body 6 no longer forms friction with the nozzle 5, but rotates normally, forming high-speed rotating stirring. The cover body 6 can adaptively adjust the stirring effect on the water body according to the flow rate of the water body through the floating of the ring body 8. When the flow rate is large, the stirring is fast, and when the flow rate is slow, the stirring is slow, thereby ensuring the stability of the output rate of the outlet pipe 11 and stabilizing the purification degree of the water body output by the outlet pipe 11.

[0028] The upper end of the nozzle 5 and the top end of the cover body 6 are both hemispherical, and the nozzle 5 has a spray hole 50 that diverges in multiple directions. The nozzle 5 with the spray hole 50 reduces the number of bubble dispersers installed in the container 1, and can fully realize the function of purifying aquaculture wastewater by suspending and stirring the microbial filter medium, thereby reducing the energy consumption of the aeration device and saving costs.

[0029] The through holes 20 are slit holes in the form of elongated holes with a predetermined length, and the slit holes are arranged at equal intervals along the radial direction of the edge of the partition 2. The slit-shaped through holes 20 can effectively block the microorganisms above the partition 2, ensure the number of microorganisms above the partition 2, and prevent the microorganisms from being discharged along with the purified water, resulting in a reduction in the purification efficiency of subsequent aquaculture wastewater.

[0030] See attached Figure 6 The distribution chamber 3 has a lower flange 31 on the outside, and the discharge chamber 4 has an upper flange 40 that is tightly matched with the upper end of the lower flange 31 , and a sealing gasket 12 is provided between the lower flange 31 and the upper flange 40 .

[0031] The sealing gasket 12 is installed on the upper end surface of the lower flange 31, and the upper flange 40 of the discharge chamber 4 is installed above the sealing gasket 12 to form an installation connection between the discharge chamber 4 and the distribution chamber 3. During use, the container 1 is installed above the distribution chamber 3, and the sealing gasket 12 is continuously compressed by the weight of the container 1. Watertightness is ensured without the need to assemble sealing parts such as bolts, thereby reducing manufacturing costs. After use, no tedious disassembly work is required. It is only necessary to drain all the water to reduce the overall weight of the container 1, and then lift the container 1 to complete the rapid separation of the container 1 and the distribution chamber 3, thereby accelerating the efficiency of installation and disassembly, and also improving the effect of disassembly, cleaning and maintenance of the entire equipment.

[0032] The efficient treatment facilities for aquaculture wastewater include: Step 1: aquaculture wastewater enters container 1 through inlet pipe 10; Step 2: The aquaculture wastewater is degraded by the microorganisms in the container 1 to form a filter. During the degradation process, the cover 6 stirs the water to accelerate the degradation reaction; Step three, the treated aquaculture wastewater passes through the partition 2, the discharge chamber 4, and the distribution chamber 3 in sequence, and is finally discharged from the outlet pipe 11.
