Description

Technical Field

[0001] The present invention relates to the technical field of wastewater purification and treatment, and particularly relates to an efficient treatment facility and method for aquaculture wastewater. Background Art

[0002] The nitrogen and phosphorus-rich wastewater generated during aquaculture is discharged into water bodies such as rivers and lakes, which is likely to cause eutrophication of the water bodies. At the same time, inside the aquaculture pond, when the concentrations of ammonia nitrogen, nitrite nitrogen, etc. continuously accumulated in the aquaculture water are too high, it will have a strong toxic effect on fish and shrimps, and even cause death. Therefore, the purification and recycling of aquaculture wastewater have 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] Existing aquaculture ponds have relatively simple structures. During the aquaculture process, the ponds need to be cleaned regularly. Otherwise, the water quality will deteriorate, causing self-pollution of the aquaculture, leading to diseases or death of the aquaculture objects. Currently, aquaculture ponds can basically not handle aquaculture wastes, and are basically static aquaculture, unable to conduct large-scale water replacement. During the middle and late stages of aquaculture, excreta such as feces and residual baits accumulate in large quantities, resulting in the deterioration of the water quality of the water body, the large growth of harmful microorganisms, and the environmental stress seriously affecting the growth and survival of the aquaculture objects, resulting in a decline in the aquaculture success rate and having a great impact on the quality and safety of aquatic products.

[0004] The Korean patent with the application number KR1020180138276 discloses a double-pipe assembled biological filter with a same-path inlet and outlet pipe. This biological filter is a biological reactor with an L-shaped pipeline formed on the partition on the inner bottom surface of the aeration tank to allow the filter medium to pass through and be stirred to form an L-shaped pipeline. It can quickly select the pipeline without using an inflow pipe and an outflow pipe without being restricted by the space of the aeration reactor, and has the technical advantage of fast assembly speed. However, in the prior art, when the biological filter uses microorganisms to treat and degrade wastewater, the microorganisms may block the water outlet, resulting in the problem of low drainage rate. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient treatment facility and method for aquaculture wastewater that is easy to assemble, has high degradation ability and is not easily blocked.

[0006] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] An efficient treatment facility for aquaculture wastewater, comprising: a container storing a microbial filter medium, the container is connected with an inflow pipe and an outflow pipe, a partition is arranged above the inner bottom surface of the container, the partition is evenly provided with through holes, the output end of the inflow pipe is located above the partition and is provided with a nozzle, and the nozzle is movably connected with a cover body.

[0008] Preferably, a columnar distribution chamber is provided at the bottom end of the partition plate. A funnel-shaped discharge chamber is formed between the partition plate and the distribution chamber. The distribution chamber is surrounded by diversion holes communicating with the discharge chamber, and the distribution chamber communicates with the outflow pipe. A certain amount of microbial filter medium is introduced into the container. The aquaculture wastewater is connected to the inflow pipe. The aquaculture wastewater can be discharged from the nozzle at the end of the inflow pipe above the partition plate and evenly distributed in the container filled with the microbial filter medium under the action of the cover body. The ammonia nitrogen content in the aquaculture wastewater is reduced by microorganisms to achieve the purification of the aquaculture wastewater. The purified water body successively enters the funnel-shaped discharge chamber through the through holes on the partition plate, then reaches the inside of the distribution chamber through the diversion holes, and finally is discharged from the outflow pipe;

[0009] The funnel-shaped discharge chamber forms a downward and inward diversion for the purified water passing through the through holes, which helps to improve the discharge rate of the purified water.

[0010] Preferably, the inflow pipe horizontally penetrates through the lower part of the distribution chamber and extends upward in the center of the distribution chamber. The outflow pipe is connected to the lower part of the distribution chamber, and the outflow pipe and the inflow pipe are arranged relatively. The part of the inflow pipe extending upward in the distribution chamber, in cooperation with the distribution chamber, forms an annular channel allowing the purified water to flow out, that is, the purified water flows entering the distribution chamber from different diversion holes can contact the outer pipe wall of the inflow pipe, reducing the possibility of water blockage caused by the impact of multiple water flows on each other. At the same time, when the purified water flow acts on the pipe wall of the inflow pipe, it can cause vibration, which helps to promote the shaking off of the pollutants attached to the inner pipe wall of the inflow pipe, reducing the risk of pipeline blockage to improve the water flow rate;

[0011] Since the inflow pipe has a vertically extending part, that is, the aquaculture wastewater is sprayed upward and outward from the nozzle, it can disturb the water body to form the suspension of microorganisms above the partition plate, which is beneficial to the degradation of aquaculture wastewater by microorganisms;

[0012] The interpenetrating setting of the inflow pipe and the distribution chamber can minimize the area of the pipelines exposed to the inside and outside of the container, optimize the space layout, so that the inflow path and the discharge path of the aquaculture wastewater do not pass through too many channels, greatly improving the efficiency of wastewater treatment.

[0013] Preferably, the cover body covers the outside of the nozzle. There is a gap between the cover body and the nozzle. The side walls of the lower part of the cover body are evenly distributed with flow grooves. The cover body can rotate relative to the nozzle, and the cover body is surrounded by blades. The aquaculture wastewater sprayed from the nozzle contacts the inner wall of the cover body through the gap space, forming a water flow diffusing to the bottom and the outside, increasing the diffusion range of the aquaculture wastewater above the partition plate, increasing the contact range between the water body and the microorganisms, and thus improving the purification efficiency.

[0014] Preferably, the blade includes an inner blade and an outer blade. The inner blade is fixed to the inner side of the cover body, and the outer blade is fixed to the outer side of the cover body. The aquaculture wastewater sprayed upward and outward by the nozzle is blocked by the cover body and acts on the inner blade of the cover body, thereby enabling the cover body to rotate. At the same time, the rotating cover body can stir the aquaculture wastewater and microorganisms above the partition through the outer blade on its outer side, preventing the microorganisms from depositing on the upper end face of the partition, promoting the homogenization of the microorganisms in the aquaculture wastewater, and improving the degradation rate of the aquaculture wastewater;

[0015] During the rotation of the cover body, the inner blade is carried to rotate outside the nozzle. The formed inner swirl cleans the nozzle, reducing the possibility of pollutants or particulate matter in the aquaculture wastewater clogging the nozzle and improving the efficiency of introducing and purifying the outflow of the aquaculture wastewater;

[0016] During the rotation of the cover body, the outer blade is carried to stir the aquaculture water and microorganisms and form a swirl. On the one hand, the swirl helps to clean the inner wall of the container above the partition, reducing the cleaning difficulty. On the other hand, the swirl is guided downward by the funnel-shaped discharge chamber after passing through the through-hole on the partition, forming a downward concentrated swirl, which helps to improve the sedimentation performance of the 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 body output by the outflow pipe does not contain large solid particles, improving the cleanliness of the wastewater treatment;

[0017] The swirl can guide the water body, prompting the microorganisms or particulate matter stuck in the through-hole to leave, further ensuring the output efficiency of the purified water body, and preventing the continuous increase of the water body above the partition and the difficulty of output, resulting in the overflow of the water body and environmental pollution.

[0018] Preferably, a ring body is fixed to the inner bottom of the cover body, and the ring body is sleeved on the part of the inflow pipe above the partition. The setting of the ring body can keep the layout of the cover body outside the nozzle, ensuring an interval distance between the nozzle and the cover body to ensure the normal output of the aquaculture wastewater, and at the same time ensuring that the cover body can rotate relative to the nozzle;

[0019] Preferably, the upper end of the nozzle and the top end of the cover body are both hemispherical, and the nozzle has injection holes diverging in multiple directions. The nozzle with injection holes reduces the installation quantity of the bubble disperser in the container and can fully realize the function of purifying the aquaculture wastewater by suspending and stirring the microbial filter medium, thereby reducing the energy consumption of the aeration device and saving costs.

[0020] Preferably, the through-hole is a slit hole in the form of an elongated hole with a predetermined length, and the slit holes are arranged radially at equal intervals along the edge of the partition. The slit-shaped through-hole can effectively block the microorganisms above the partition, ensuring the number of microorganisms above the partition and preventing the microorganisms from being discharged along with the purified water body, resulting in the reduction of the purification efficiency of the subsequent aquaculture wastewater.

[0021] Preferably, the distribution chamber has a lower flange on the outside, the discharge chamber has an upper flange that fits tightly with the upper end of the lower flange, and a gasket is provided between the lower flange and the upper flange. The gasket is installed on the upper end face of the lower flange, and then the upper flange of the discharge chamber is installed above the gasket to form the installation connection between the discharge chamber and the distribution chamber. During use, the container is installed above the distribution chamber, and the gasket is continuously compressed by the weight of the container, ensuring watertightness without the need to assemble seals such as bolts, reducing manufacturing costs. After use, there is no need for cumbersome disassembly work. Only by draining all the water, reducing the overall weight of the container, and then lifting the container can the container be quickly separated from the distribution chamber, accelerating the installation and disassembly efficiency, and at the same time improving the disassembly, cleaning, and maintenance effects of the entire device.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The downward pressing assembly connection of the container, the distribution chamber, and the discharge chamber is convenient for disassembly and cleaning, reducing time costs; The annular channel formed by the distribution chamber and the inflow pipe can avoid water blockage, reduce the risk of pipeline blockage at the same time, and improve the water flow rate; The cover body rotates under the impact of water flow to form agitation of the water body, promoting water body homogenization and improving the purification rate of microorganisms for aquaculture wastewater; The rotating blades agitate the water body to form a swirl, which can cooperate with the distribution chamber to promote solid sedimentation, improve the water body cleanliness, and at the same time achieve centralized collection of solids for easy treatment; The rotating inner blades can self-clean the nozzles to avoid blockage of the holes by particulate matter.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] First, the concepts involved in the present application will be described in conjunction with the accompanying drawings. It should be noted here that the following descriptions of each concept are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application; at the same time, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] See the attached Figure 1 - attached Figure 3 , An efficient aquaculture wastewater treatment facility, including: a container 1 storing a microbial filtration medium, the container 1 is connected with an inflow pipe 10 and an outflow pipe 11, a partition plate 2 is arranged above the inner bottom surface of the container 1, the partition plate 2 is uniformly provided with through holes 20, the output end of the inflow pipe 10 is located above the partition plate 2 and is provided with a sprayer, and the sprayer is movably connected with a cover body 6.

[0034] A columnar distribution chamber is arranged at the bottom end of the partition plate 2, a funnel-shaped discharge chamber 4 is formed between the partition plate 2 and the distribution chamber, flow guiding holes communicating with the discharge chamber 4 are arranged around the distribution chamber, and the distribution chamber communicates with the outflow pipe 11.

[0035] It should be noted that the funnel-shaped discharge chamber 4 includes a conical sleeve with the small end downward, the top of the distribution chamber abuts against the center of the bottom end of the partition plate 2, the upper edge of the conical sleeve is located at the outer edge of the lower end of the partition plate 2, and the inner edge of the bottom of the conical sleeve cooperates with the outer wall of the distribution chamber.

[0036] A certain amount of microbial filtration medium is introduced into container 1. The aquaculture wastewater is connected to the influent pipe 10. The aquaculture wastewater can be discharged from the nozzle 5 at the end of the influent pipe 10 above the partition 2 and evenly distributed in the container 1 filled with the microbial filtration medium under the action of the cover 6. The ammonia nitrogen content in the aquaculture wastewater is reduced by the microorganisms to achieve the purification of the aquaculture wastewater. The purified water body successively enters the funnel-shaped discharge chamber 4 through the through holes 20 on the partition 2, then reaches the inside of the distribution chamber through the diversion holes 30, and finally is discharged from the effluent pipe 11;

[0037] The funnel-shaped discharge chamber 4 forms a downward and inward diversion for the purified water passing through the through holes 20, which helps to improve the discharge rate of the purified water.

[0038] The influent pipe 10 horizontally penetrates the lower part of the distribution chamber and extends upward in the center of the distribution chamber. The effluent pipe 11 is connected to the lower part of the distribution chamber, and the effluent pipe 11 is arranged opposite to the position of the influent pipe 10. The part of the influent pipe 10 extending upward in the distribution chamber, in cooperation with the distribution chamber, forms an annular channel allowing the purified water to flow out, that is, the purified water flows entering the distribution chamber from different diversion holes 30 can contact the outer pipe wall of the influent pipe 10, reducing the possibility of water blockage caused by the impact of multiple water flows on each other. At the same time, when the purified water flow acts on the pipe wall of the influent pipe 10, it can cause vibration, which helps to promote the shaking off of the pollutants attached to the inner pipe wall of the influent pipe 10, reducing the risk of pipeline blockage to improve the water circulation rate;

[0039] Since the influent pipe 10 has a vertically extending part, that is, the aquaculture wastewater is ejected upward and outward from the nozzle 5, it can disturb the water body to form the suspension of microorganisms above the partition 2, which is beneficial to the degradation of the aquaculture wastewater by the microorganisms;

[0040] The interpenetrating setting of the influent pipe 10 and the distribution chamber can minimize the area of the pipelines exposed to the inside and outside of the container 1, optimize the space layout, so that the inflow path and the discharge path of the aquaculture wastewater do not pass through too many channels, greatly improving the efficiency of wastewater treatment.

[0041] See Appendix Figure 4 - Appendix Figure 5 As shown in the attached figure, the cover 6 covers the outside of the nozzle 5. There is a gap between the cover 6 and the nozzle 5. The side walls at the lower part of the cover 6 are evenly distributed with flow grooves 60. The cover 6 can rotate relative to the nozzle 5, and the cover 6 is surrounded by blades 7.

[0042] The blade 7 includes an inner blade 70 and an outer blade 71. The inner blade 70 is fixed to the inner side of the cover 6, and the outer blade 71 is fixed to the outer side of the cover 6. The aquaculture wastewater sprayed upward and outward by the nozzle 5 is blocked by the cover 6 and acts on the inner blade 70 of the cover 6, thereby enabling the cover 6 to rotate. At the same time, the rotating cover 6 can stir the aquaculture wastewater and microorganisms above the partition plate 2 through the outer blade 71 on its outer side, avoiding the deposition of microorganisms on the upper end surface of the partition plate 2, promoting the homogenization of microorganisms in the aquaculture wastewater, and increasing the degradation rate of the aquaculture wastewater;

[0043] During the rotation of the cover 6, the inner blade 70 is carried to rotate outside the nozzle 5, and the formed inner swirl cleans the nozzle 5, reducing the possibility of pollutants or particulate matter in the aquaculture wastewater clogging the nozzle 5 and increasing the efficiency of the introduction and purification of the aquaculture wastewater;

[0044] During the rotation of the cover 6, the outer blade 71 is carried to stir the aquaculture water and microorganisms and form a swirl. On the one hand, the swirl helps to clean the inner wall of the container 1 above the partition plate 2, reducing the cleaning difficulty. On the other hand, after passing through the through hole 20 on the partition plate 2, the swirl is guided downward by the funnel-shaped discharge chamber 4 to form a downward concentrated swirl, which helps to improve the sedimentation performance of the 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 body output by the outflow pipe 11 does not contain large solid particles, improving the cleanliness of the wastewater treatment;

[0045] The swirl can guide the water body, prompting the microorganisms or particulate matter clamped in the through hole 20 to leave, further ensuring the output efficiency of the purified water body, and avoiding the continuous increase of the water body above the partition plate 2, which is difficult to output and causes the water body to overflow and pollute the environment.

[0046] A ring body 8 is fixed to the inner bottom of the cover 6, and the ring body 8 is sleeved on the part of the inflow pipe 10 above the partition plate 2. The setting of the ring body 8 can keep the cover 6 arranged outside the nozzle 5, so that there is a spacing distance between the nozzle 5 and the cover 6 to ensure the normal output of the aquaculture wastewater, and at the same time ensure that the cover 6 can rotate relative to the nozzle 5;

[0047] The annular body 8 is made of foam material and has buoyancy. The annular body 8 can rotate and slide on the outside of the part of the influent pipe 10 located on the partition plate 2. When the influent pipe 10 inputs aquaculture wastewater into the container 1, the inner wall of the cover body 6 receives the impact of the water body at the top. At this time, the cover body 6 floats up and down relative to the spray head 5 under the influence of the buoyancy of the bottom annular body 8. On the one hand, the cover body 6 longitudinally slides and drives the outer blades 71 to rotate, promoting water body disturbance, stirring the water bodies at different height layers above the partition plate 2, promoting the exchange of the upper water body and the lower water body, improving the homogenization of the wastewater and microorganisms, and stabilizing the purification degree of the output water body. On the other hand, the annular body 8 that slides up and down can scrape off the pollutants, microorganisms and sediment attached to the outside of the spray head 5, ensure that the water body output by the spray head 5 is unobstructed, reduce the maintenance frequency, and improve the stability of water body treatment.

[0048] When the output rate of the influent pipe 10 is low, the storage volume of the aquaculture wastewater above the partition plate 2 is also low. At this time, the buoyancy received by the annular body 8 is low, and the overall height of the cover body 6 moves down, resulting in the top of the inner wall of the cover body 6 blocking above the spray head 5. That is, the water body ejected from the spray holes 50 acts more on the inner side wall of the cover body 6, and the friction between the top of the cover body 6 and the spray head 5 reduces the rotation speed of the cover body 6, forming a low-speed rotation and stirring; when the output rate of the influent pipe 10 is high, the storage volume of the aquaculture wastewater above the partition plate 2 is also high. At this time, the buoyancy received by the annular body 8 is high, and the overall height of the cover body 6 moves up, resulting in a sufficient interval space between the top of the inner wall of the cover body 6 and the spray head 5 and being filled with water. At this time, the top of the cover body 6 no longer forms friction with the spray head 5, but rotates normally, forming a high-speed rotation and stirring. Through the floating of the annular body 8, the cover body 6 can adaptively adjust the stirring effect on the water body according to the water body flow rate. When the flow rate is large, the stirring is fast; when the flow rate is slow, the stirring is slow, ensuring the stability of the output rate of the outlet pipe 11 and also stabilizing the purification degree of the water body output by the outlet pipe 11.

[0049] The upper end of the spray head 5 and the top end of the cover body 6 are both hemispherical, and the spray head 5 has spray holes 50 that diverge in multiple directions. The spray head 5 with the spray holes 50 reduces the installation quantity of the bubble dispersers 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 devices and saving costs.

[0050] The through holes 20 are slit holes in the form of slender holes with a predetermined length, and the slit holes are arranged radially at equal intervals along the edge of the partition plate 2. The slit-shaped through holes 20 can effectively block the microorganisms above the partition plate 2, ensure the number of microorganisms above the partition plate 2, and avoid the microorganisms being discharged along with the purified water body, resulting in the reduction of the purification efficiency of the subsequent aquaculture wastewater.

[0051] See the appendix Figure 6, the distribution chamber 3 has a lower flange 31 on the outside, the discharge chamber 4 has an upper flange 40 that closely fits with the upper end of the lower flange 31, and a gasket 12 is provided between the lower flange 31 and the upper flange 40.

[0052] The gasket 12 is installed on the upper end face of the lower flange 31, and then by installing the upper flange 40 of the discharge chamber 4 above the gasket 12, the installation connection between the discharge chamber 4 and the distribution chamber 3 is formed. During use, the container 1 is installed above the distribution chamber 3, and the gasket 12 is continuously pressed by the weight of the container 1, ensuring watertightness without the need to assemble seals such as bolts, reducing manufacturing costs. And after use, there is no need for cumbersome disassembly work. Only by discharging all the water body, reducing the overall weight of the container 1, and then lifting the container 1 can the quick separation of the container 1 and the distribution chamber 3 be completed, accelerating the installation and disassembly efficiency, and at the same time improving the effect of disassembling, cleaning and maintaining the entire equipment.

[0053] An efficient treatment facility for aquaculture wastewater, and the specific treatment method is as follows:

[0054] Step 1, the aquaculture wastewater enters the container 1 through the influent pipe 10;

[0055] Step 2, the aquaculture wastewater is degraded by microorganisms in the container 1 to form filtration. During the degradation process, the cover 6 stirs the water body to accelerate the degradation reaction;

[0056] Step 3, the treated aquaculture wastewater passes through the partition 2, the discharge chamber 4, and the distribution chamber 3 in sequence, and finally is discharged from the effluent pipe 11.

Any person skilled in the art, without departing from the scope of the technical means disclosed in the content of the present invention, may make some changes or modifications to other equivalent embodiments, but should still be regarded as the same technology or embodiment as the present invention in essence.
