Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and in particular to a digital aquaculture water nitrogen removal system. Background Art

[0002] Aquatic products are delicious, rich in protein, and have higher nutritional value than other meats. They are an indispensable ingredient in people's daily lives. In recent years, with the gradual improvement of environmental protection requirements, in order to avoid reservoir pollution and damage to the ecological balance of the water environment, traditional cage farming that relies on reservoirs, lakes, and rivers has been gradually banned, and aquaculture has gradually moved to land-based farming. Pond farming has problems such as water exchange, drainage, and sewage discharge, and is also restricted by geographical conditions, making it difficult to achieve large-scale farming. Therefore, the shift from aquaculture to land-based farming and factory farming has become a major trend in the aquaculture industry.

[0003] Ammonia nitrogen is produced in the aquaculture pond during the aquaculture process, and then converted into nitrite and nitrate under the action of microorganisms. It is necessary to remove ammonia nitrogen from the aquaculture water in time to greatly reduce the production of nitrite and nitrate. Therefore, it is necessary to supplement oxygen into the water at any time to enable it to survive and grow normally. At the same time, it is necessary to change the water on time or keep the water flowing, and continuously discharge the fish feces and food residues to reduce the ammonia content in the water. The existing nitrogen removal filtration system has a relatively complex structure, poor nitrogen removal effect on sewage, low nitrogen removal efficiency, and needs to be shut down for maintenance. The operation process is cumbersome, time-consuming and labor-intensive, which to a certain extent hinders the development of the aquaculture industry. Therefore, it is a technical problem that technicians in this field need to further consider and solve to establish a set of aquaculture water nitrogen removal filtration system with simple structure and excellent effect, so that it can achieve the purpose of reducing the nitrogen content in the water.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 As shown, a digital aquaculture water nitrogen removal system includes a regeneration liquid tank 1, an aquaculture tank 2, a first filtration system 3, a second filtration system 4, a clean water tank 5 and a sewage treatment tank 6. The first filtration system 3 and the second filtration system 4 are loaded with a special filter material for adsorbing ammonia nitrogen in the aquaculture water, so that ammonia nitrogen compounds, free ammonia (NH3) and ammonium ions (NH 4 + ) is converted into harmless gaseous nitrogen and discharged. When the specific filter material is saturated, it needs to be desorbed, i.e. regenerated. The regeneration liquid pool 1 is loaded with regeneration liquid, which is used to desorb ammonia nitrogen substances adsorbed on the specific filter material to restore the total nitrogen removal capacity.

[0019] The regeneration liquid pool 1 is connected to the first filter system 3 through a first inlet pipe 11 and a first outlet pipe 12. The first inlet pipe 11 is installed with a first inlet valve 111. The first inlet valve 111 controls the regeneration liquid in the regeneration liquid pool 1 to enter the first filter system 3. The first outlet pipe 12 is installed with a first outlet valve 121. The first outlet valve 121 controls the regeneration liquid in the first filter system 3 to flow back to the regeneration liquid pool 1 for recycling. The regeneration liquid pool 1 is connected to the second filter system 4 through a second inlet pipe 13 and a second outlet pipe 14. A second inlet valve 131 is installed on the inlet pipe 13, and the second inlet valve 131 controls the regeneration liquid in the regeneration liquid pool 1 to enter the second filter system 4. A second outlet valve 141 is installed on the second outlet pipe 14, and the second outlet valve 141 controls the regeneration liquid in the second filter system 4 to flow back to the regeneration liquid pool 1 for recycling. A total nitrogen online monitor 15 is provided in the regeneration liquid pool 1, and the total nitrogen online monitor 15 is used to monitor the total nitrogen content of the regeneration liquid in real time. When the total nitrogen content is too high, the total nitrogen online monitor 15 will issue an alarm to prompt the replenishment or replacement of the regeneration liquid.

[0020] The aquaculture pond 2 is connected to the first filtering system 3 through a first aquaculture water outlet pipe 21 and a first aquaculture water inlet pipe 22. The first aquaculture water outlet pipe 21 is connected to the water inlet end of the first filtering system 3. The first aquaculture water outlet pipe 21 is provided with a first aquaculture water outlet valve 211. The first aquaculture water outlet valve 211 is used to control the aquaculture water in the aquaculture pond 2 to enter the first filtering system 3 for purification; the first aquaculture water inlet pipe 22 is connected to the water outlet end of the first filtering system 3. The first aquaculture water inlet pipe 22 is provided with a first aquaculture water inlet valve 221. The first aquaculture water inlet valve 221 is used to control the water body purified by the first filtering system 3 to flow back to the aquaculture pond 2, thereby realizing the recycling of aquaculture water; The breeding pond 2 is connected to the second filtering system 4 through a second breeding water outlet pipe 23 and a second breeding water inlet pipe 24. The second breeding water outlet pipe 23 is connected to the water inlet end of the second filtering system 4. A second breeding water outlet valve 231 is provided on the second breeding water outlet pipe 23. The second breeding water outlet valve 231 is used to control the breeding water in the breeding pond 2 to enter the second filtering system 4 for purification; the second breeding water inlet pipe 24 is connected to the water outlet end of the second filtering system 4. A second breeding water inlet valve 241 is provided on the second breeding water inlet pipe 24. The second breeding water inlet valve 241 is used to control the water body purified by the second filtering system 4 to flow back into the breeding pond 2, thereby realizing the recycling of breeding water.

[0021] The first filter system 3 and the second filter system 4 are two sets of devices with the same structure. The first filter system 3 and the second filter system 4 work independently. The structure of the first filter system 3 is described below by taking the first filter system 3 as an example. The first filter system 3 includes a filter 32 and a booster pump 31. The filter 32 is connected to the booster pump 31 through a pipeline. The booster pump 31 is connected to the outlet pipe of the aquaculture water and the regeneration liquid. A specific filter material is placed in the filter, and the specific filter material can effectively adsorb ammonia nitrogen. A total nitrogen online monitor is also provided in the filter 32 (as shown in the figure). The total nitrogen online monitor is used to monitor the total nitrogen content in the filter 32 to determine whether the specific filter material needs to be desorbed by the regeneration liquid.

[0022] The clean water tank 5 is connected to the first filter system 3 through a first clean water pipe 51, and the clean water tank 5 is connected to the second filter system 4 through a second clean water pipe 52. The clean water tank 5 is loaded with clean water for flushing the first filter system 3 and the second filter system 4. When there are too many impurities in the filter system, its pressure will rise and the working flow will decrease. It is necessary to clean it to remove impurities. Cleaning the impurities in the filter system with clean water can effectively remove impurities to restore the working flow; the sewage treatment tank 6 is connected to the first filter system 3 and the second filter system 4 respectively, and the sewage that has been cleaned by the first filter system 3 and the second filter system 4 flows into the sewage treatment tank 6 for collection; the clean water tank 5 also includes a return pipe 53, which is connected to the first outlet pipe 12 and the second outlet pipe 14 respectively, and a valve is provided at the connection position. The return pipe 53 allows the clean water tank 5 to maintain a loop with the first filter system 3 and the second filter system 4 to realize clean water circulation. If the first filter system 3 or the second filter system 4 is not in operation for a long time, odor will be generated, so it is necessary to maintain the clean water circulation operation state.

[0023] The working principle of the utility model is as follows:

[0024] 1. Under normal circumstances, one of the first filter system 3 and the second filter system 4 is in use, and the other is in standby. For example, when the first filter system 3 is working, the second filter system 4 is in a clean water circulation operation state. At this time, the valves on the first aquaculture water outlet pipe 21 and the first aquaculture water inlet pipe 22 are opened respectively, and the booster pump 31 in the first filter system 3 draws the water in the aquaculture pool 2 into the filter 32 through the first aquaculture water outlet pipe 21 for filtration, and returns the water to the aquaculture pool 2 through the first aquaculture water inlet pipe 22; at the same time, the valve on the return pipe 53 is opened, and the return pipe 53 allows the clean water pool 5 and the second filter system 4 to maintain a loop to realize clean water circulation;

[0025] 2. When there are too many impurities in the first filter system 3, close the valves on the first aquaculture water outlet pipe 21 and the first aquaculture water inlet pipe 22, and the first filter system 3 stops working. At the same time, open the valves on the second aquaculture water outlet pipe 23 and the second aquaculture water inlet pipe 24, and the second filter system 4 starts working;

[0026] 3. Open the valve on the first clean water pipe 51, and the booster pump 31 pumps the clean water in the clean water tank 5 into the filter 32 to clean the filter 32, and the cleaned sewage enters the sewage treatment tank 6;

[0027] 4. When the total nitrogen online monitor of the filter 32 in the first filtration system 3 detects that the total nitrogen content in the filter 32 is too high, the valves on the first aquaculture water outlet pipe 21 and the first aquaculture water inlet pipe 22 are closed, the first filtration system 3 stops working, and the valves on the first inlet pipe 11 and the first outlet pipe 12 are opened at the same time, and the booster pump 31 pumps the regeneration liquid in the regeneration liquid pool 1 into the filter 32 to desorb the specialized filter material in the filter to restore its total nitrogen removal capacity;

[0028] 5. The total nitrogen online monitor 15 in the regeneration liquid pool 1 monitors the total nitrogen content of the regeneration liquid in real time. When the total nitrogen content of the regeneration liquid in the regeneration liquid pool 1 is too high, the total nitrogen online monitor 15 will issue an alarm to prompt the regeneration liquid to be supplemented or replaced;

[0029] 6. The first filter system 3 and the second filter system 4 are used alternately without affecting each other. The two filter systems work in turns to ensure that the aquaculture water is continuously purified. When one filter system is in use, the other filter system maintains a clean water circulation state.

[0030] The utility model arranges two independent filtering systems, and the filtering system transfers nitrogen in the water to a specific filter material by a physical adsorption reaction method, thereby achieving the purpose of reducing the nitrogen content in the aquaculture water body. The two filtering systems are used separately in turn, and can continuously purify the aquaculture water without stopping. The system has a simple structure, is easy to operate, and has a long service life. It can achieve matching water quality regulation and optimize the water quality treatment process through digital monitoring and regulation, thereby reducing energy consumption and improving efficiency.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
