Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and more specifically to a distributed microcirculation water system suitable for industrial aquaculture. Background Art

[0002] Factory aquaculture is a commonly used method in the aquaculture industry. It is highly controllable, capable of planned and stable production, and can be managed semi-automatically or fully automatically. It has many advantages, such as small footprint, high yield, little impact from the natural environment, continuous production throughout the year, high economic benefits, and automated operation and management. The closed circulating water system is not easy to pollute the marine environment. Since the water is constantly circulating, water consumption is also low. It is an environmentally friendly, green and efficient farming method.

[0003] At present, the mode commonly used in factory aquaculture in the prior art is mostly a centralized circulating water system. However, in this mode, a set of circulating water treatment equipment needs to treat all the aquaculture water in the factory, which brings the following problems:

[0004] First, the centralized circulating water system has limited water treatment capacity, which limits the size of the factory. Otherwise, when the circulating water system needs to be upgraded as a whole, the cost will increase dramatically. In addition, the centralized circulating water system does not have the ability to expand and cannot be expanded once deployed.

[0005] Second, the centralized circulating water system has the risk of single-point failure. Once the system fails and cannot be repaired in time, all the farmed animals in the factory will die, causing huge losses.

[0006] Therefore, how to solve the problem that the circulating water system used in factory aquaculture in the prior art does not have the expansion capability and has the risk of single point failure has become an important technical problem to be solved by technical personnel in this field. Summary of the invention

[0007] The purpose of the present invention is to provide a distributed micro-circulation water system suitable for factory aquaculture, which solves the problem of lack of expansion capability and single point failure risk compared with the circulating water system used in factory aquaculture in the prior art.

[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise specified, "multiple" means two or more than two; the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] The purpose of this specific embodiment is to provide a distributed micro-circulation water system suitable for factory aquaculture, which can solve the problem that the circulating water system used in factory aquaculture in the prior art has no expansion capability and has the risk of single point failure.

[0034] The following embodiments are described in detail with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention described in the claims. In addition, the entire content of the structure represented by the following embodiments is not limited to the solution required as the invention described in the claims.

[0035] Please refer to Figure 1-Figure 2 The present embodiment provides a distributed microcirculation water system suitable for factory aquaculture, including a breeding pond module and a water treatment module, wherein the water treatment module and the breeding pond module are circularly connected through a circulating water network, the circular connection means that the outlet water of the breeding pond module is connected with the inlet water of the water treatment module, and the outlet water of the water treatment module is connected with the inlet water of the breeding pond module. The breeding pond module includes a plurality of breeding ponds 1 connected in parallel, wherein the breeding pond 1 has a space for storing water for providing aquatic products, and the breeding pond 1 has a water inlet and a water outlet, and the water treatment module includes a plurality of microcirculation water treatment devices 2 connected in parallel, wherein the microcirculation water treatment device 2 can treat wastewater from the breeding pond 1, and the microcirculation water treatment device 2 has a water inlet and a water outlet. During operation, the wastewater in each breeding pool 1 in the breeding pool module is collected centrally, and then dispersed into each micro-circulation water treatment equipment 2 in the water treatment module. The treated water is collected centrally again, and then dispersed into each breeding pool 1 in the breeding pool module, and the cycle repeats. Since the breeding pool module and the water treatment module are two independent modules, in actual application, the breeding pool module and the water treatment module can be expanded as needed according to the actual production capacity and production plan, that is, the breeding pool 1 and the micro-circulation water treatment equipment 2 are increased accordingly. Moreover, even if a certain micro-circulation water treatment equipment 2 fails, the operation of the entire system can still be maintained without paralysis due to the existence of other micro-circulation water treatment equipment 2, thereby ensuring the survival of aquatic animals in the breeding pool 1 and greatly reducing the risk. This method of splitting a centralized large system into many controllable small systems solves the problem of the circulating water system for factory aquaculture applications in the prior art not having expansion capabilities and the risk of single point failure by means of divide and conquer.

[0036] Moreover, compared with the centralized circulating water system, the distributed micro-circulating water system suitable for factory-scale aquaculture does not have high requirements for the water treatment capacity of a single micro-circulating water treatment device 2, as long as the total treatment capacity of multiple micro-circulating water treatment devices 2 can meet the water treatment needs of all aquaculture ponds 1. Moreover, if the total wastewater treatment capacity of the water treatment module is insufficient, it is only necessary to simply increase the number of micro-circulating water treatment devices 2 to meet the demand.

[0037] As a specific implementation scheme, the total water storage capacity of the breeding pond module is M. Since the amount of water that the microcirculation water treatment equipment 2 can bear to treat is fixed, the amount of water treated by each microcirculation water treatment equipment 2 is N, and the water treatment module includes M / N microcirculation water treatment equipment 2; wherein M and N are both positive numbers, M is greater than or equal to N, and M is preferably set to an integer multiple of N. A single microcirculation water treatment equipment 2 can treat the wastewater volume of one or more breeding ponds 1.

[0038] As a preferred implementation scheme, the total water storage capacity of the breeding pond module is M. Since the amount of water that the microcirculation water treatment equipment 2 can bear is fixed, the amount of water processed by each microcirculation water treatment equipment 2 is N, and the water treatment module includes M / N+1 microcirculation water treatment equipment 2; wherein, M and N are both positive numbers, M is greater than or equal to N, and M is preferably set to an integer multiple of N. In this way, the extra microcirculation water treatment equipment 2 serves as redundancy for the entire system. When a microcirculation water treatment equipment 2 fails, it can intervene in time and assume the work of the failed equipment, so that the entire system can always be in a normal and ideal operating state, ensuring efficient production benefits.

[0039] A more specific implementation scheme is to set up a circulating water network including a wastewater network and a treated water network. The wastewater network includes a wastewater main pipe 3 and a wastewater branch pipe 4. The treated water network includes a treated water main pipe 5 and a treated water branch pipe 6. The outlet of the culture pond 1 and the water inlet of the microcirculation water treatment equipment 2 are both connected to the wastewater main pipe 3 through the wastewater branch pipe 4. The water inlet of the culture pond 1 and the water outlet of the microcirculation water treatment equipment 2 are both connected to the treated water main pipe 5 through the treated water branch pipe 6. That is, the wastewater in each culture pond 1 is discharged to the wastewater main pipe 3 through the wastewater branch pipe 4 and collected centrally. Then, the wastewater in the wastewater main pipe 3 passes through another wastewater branch pipe 4 again and enters each microcirculation water treatment equipment 2 in a dispersed manner. The treated water is discharged again and collected centrally into the treated water main pipe 5 through the treated water branch pipe 6. Then, the treated water enters each culture pond 1 in a dispersed manner through another treated water branch pipe 6.

[0040] In order to facilitate the adjustment of the number of microcirculation water treatment equipment 2 and breeding pond 1 involved in the operation according to actual conditions during operation, valves 7 are provided at the water inlet and outlet of the microcirculation water treatment equipment 2, and valves 7 are provided at the water inlet and outlet of the breeding pond 1.

[0041] In addition, please refer to Figure 3 The microcirculation water treatment equipment 2 is specifically configured to include a lifting pump 8, a purification device, a disinfection device, and a chassis. The chassis has a hollow structure. The lifting pump 8, the purification device, and the disinfection device are connected and are all arranged in the chassis. The lifting pump 8 is used to provide power for the flow of fluid. The purification device can remove impurities in the wastewater, and the disinfection device can disinfect and sterilize the wastewater. Since the resistance of the wastewater flowing in the purification device and the disinfection device is relatively large, it is preferred that the lifting pump 8 is arranged close to the water inlet so that the wastewater has sufficient pressure to enter the purification device and the disinfection device. The water inlet of the microcirculation water treatment equipment 2 is connected to the lifting pump 8, and the disinfection device is connected to the water outlet of the microcirculation water treatment equipment 2.

[0042] Furthermore, the purification device is provided, which specifically includes a microfilter 9, a suspended filler body 10, a brush filler body 11, a new filler body 12, and a protein separator 13. The wastewater passes through the microfilter 9, the suspended filler body 10, the brush filler body 11, the new filler body 12, and the protein separator 13 in sequence. Among them, the microfilter 9 is used to intercept solid particles in the wastewater, and is a preliminary purification device for achieving solid-liquid separation; the suspended filler body 10 is filled with a porous rotating spherical suspended filler, which is divided into an inner and outer double-layer sphere, the outer layer is a hollow fishnet sphere, and the inner layer is a rotating sphere, which mainly acts as a biofilm carrier and also has the function of intercepting suspended matter, and has the characteristics of strong biological adhesion, large specific surface area, high porosity, good chemical and biological stability, durability, no dissolution of harmful substances, no secondary pollution, easy replacement, acid and alkali resistance, anti-aging, not affected by water flow, and long service life; the brush filler body 11 is filled with a filter brush, and the use of the filter brush Long service life, good oxygenation performance, fast start-up and biofilm formation, easy biofilm removal and renewal, simple operation and management, corrosion resistance, no clogging, and no agglomeration; the new filler body 12 is filled with other fillers known in the art that are suitable for water filtration treatment in aquaculture, and any filler can be used; the protein separator 13, also known as the protein separator, uses the principle that the surface of bubbles in the water can absorb various granular dirt and soluble organic matter mixed in the water, and adopts oxygenation equipment or vortex pumps to generate a large number of bubbles. These bubbles are all concentrated on the water surface to form foam, and the foam that absorbs the dirt is collected in a container on the water surface, and it will turn into turbid liquid and then be discharged.

[0043] Furthermore, the disinfection device includes an ozone generator 14, an ozone adsorbent 15, and an ultraviolet germicidal lamp 16, wherein the ozone generated by the ozone generator 14 can oxidize viruses and pathogens in the wastewater, thereby sterilizing and disinfecting, and the ozone adsorbent 15 adsorbs the residual ozone to prevent it from entering the breeding pond 1, and finally the ultraviolet germicidal lamp 16 performs another thorough sterilization and disinfection treatment. The microcirculation water treatment equipment 2 is also provided with an equipment room 17 to monitor the operation of each structure.

[0044] It should be noted that the microcirculation water treatment device 2 has the same water treatment principle as the circulating water treatment device in the centralized circulating water system in the prior art, and their specific structures can also correspond one to one, so they will not be described in detail in this article.

[0045] As a preferred embodiment, the water treatment module includes A microcirculation water treatment devices 2 connected in parallel, and the aquaculture pool module includes X*A aquaculture pools 1 connected in parallel. All microcirculation water treatment devices 2 and all aquaculture pools 1 are arranged in a rectangular array; wherein A and X are both positive integers greater than or equal to 1. In this way, the array arrangement is large-scale, convenient for expansion around, and reasonable use of factory space. It is preferred to set X equal to 2, that is, each microcirculation water treatment device 2 is responsible for processing the wastewater volume of two aquaculture pools 1.

[0046] A microcirculation water treatment devices 2 are arranged in a row, and A breeding ponds 1 are arranged in a row, that is, all breeding ponds 1 are arranged in X rows, and each microcirculation water treatment device 2 is located in a column with the X breeding ponds 1. Such an arrangement facilitates the horizontal expansion of the breeding pond modules and the water treatment modules, and is highly feasible for expanding the scale of factory breeding.

[0047] In summary, a breeding pond module and a water treatment module can form a production workshop. In order to meet the needs of factory scale expansion, the above-mentioned production workshop can be modularly replicated. There are multiple independent production workshops, and each production workshop is a complete distributed micro-circulation water system, and there are no pipes connecting each other. A factory can be composed of countless workshops, each of which can guarantee sufficient water treatment capacity and is highly available. In this way, the scale of the entire factory can be large or small, the smallest can be a production workshop, and the largest can be infinitely replicated, so as to effectively control the cost of factory construction. It is also possible to accurately match and meet the water treatment needs of the breeding pond 1 by increasing or decreasing the number of micro-circulation water treatment equipment 2, and the factory can be flexibly deployed and flexibly produced.

[0048] It is understood that the same or similar parts in the above embodiments can refer to each other, and the content not described in detail in some embodiments can refer to the same or similar content in other embodiments. The multiple solutions provided by the present invention include the basic solution itself, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0049] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
