Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquaculture technology, and in particular relates to a factory-scale recirculating aquaculture system for shrimp farming. Background Technology
[0002] Currently, shrimp farming in aquaculture is carried out in large ponds. However, shrimp excrement contains ammonia nitrogen, which is converted into toxic substances such as nitrite nitrogen. Consuming shrimp containing nitrite nitrogen can lead to the formation of carcinogens in the human body, posing a threat to human health. Therefore, the water in the ponds needs to be changed frequently during shrimp farming, with 10-50% (or even more) of the water replaced each time. Assuming daily water changes, a pond diameter of 15 meters, and a water depth of 1 meter, each water change requires the removal of 18-88 cubic meters of water. Frequent water changes not only waste water resources but also impose significant economic burdens on farmers, greatly increasing production costs and ultimately leading to high shrimp selling prices. Summary of the Invention
[0003] The purpose of this invention is to provide a factory-scale recirculating aquaculture system for shrimp farming that reduces the farming costs of shrimp.
[0004] The purpose of this utility model is to solve the following problem:
[0005] A factory-scale recirculating aquaculture system for shrimp farming includes a culture pond, a treatment pond on one side of the culture pond, and the bottoms of the culture pond and the treatment pond are connected by a circulation pipe. The treatment pond contains a bacterial house occupying 30-70% of its volume. The inlet pipe of a water pump is connected to the upper part of the inner cavity of the treatment pond, and the outlet pipe is connected to the inner cavity of the culture pond. The bacterial house is provided with nitrifying bacteria and / or nitrite-oxidizing bacteria. A first drainage pipe extending outward from the outer side of the culture pond is provided on the inner bottom of the culture pond, and a first drainage valve is provided on the first drainage pipe.
[0006] As a further optimization of the above technical solution, the inner diameter of the aquaculture pond is 5-15 meters and the inner cavity height is 0.9-1.2 meters, and the inner diameter of the treatment pond is 5-15 meters and the inner cavity height is 0.9-1.2 meters.
[0007] As a further optimization of the above technical solution, the aquaculture pond and treatment pond are containers with an open top made of cement, metal or plastic materials.
[0008] As a further optimization of the above technical solution, the bacterial house is made of plastic, rubber or other polymer materials.
[0009] As a further optimization of the above technical solution, the inner bottom of the aquaculture pond has a conical surface, and the inlet of the first drainage pipe is located at the lowest point of the conical surface.
[0010] As a further optimization of the above technical solution, the bacterial house is a cuboid of 16cm×4cm×4cm or a cylinder with a height of 16cm and a diameter of 4cm, and the bacterial house is covered with micropores for bacterial reproduction and growth.
[0011] As a further optimization of the above technical solution, a second drainage pipe extending outward from the outer side of the treatment tank is connected to the inner bottom of the treatment tank, and a second drainage valve is installed on the second drainage pipe. A water valve is also connected to the circulation pipe.
[0012] As a further optimization of the above technical solution, a support is provided on the top of the treatment pool or aquaculture pool, and the water pump is installed on the support.
[0013] As a further optimization of the above technical solution, a filter screen is installed on the inlet of the circulation pipe located in the aquaculture pond.
[0014] As a further optimization of the above technical solution, the bottom of the treatment tank and / or aquaculture tank is provided with two or more aeration pipes, and the aeration pipes are connected to the air outlet of a blower or air pump installed outside the treatment tank and / or aquaculture tank through an air supply pipe.
[0015] The advantages of this invention compared to the prior art are:
[0016] 1. This utility model involves planting nitrifying bacteria and / or nitrite-oxidizing bacteria in a bacterial house within a treatment tank. As the nitrifying bacteria and / or nitrite-oxidizing bacteria multiply in large quantities, they react with ammonia nitrogen in the shrimp excrement in the aquaculture tank to form non-toxic substances such as nitrate nitrogen salts. The water containing these non-toxic substances can be pumped into the aquaculture tank to continue raising shrimp.
[0017] 2. When the pump is working, the water containing ammonia nitrogen in the aquaculture pond flows into the treatment pond through the water valve on the circulation pipe. In the treatment pond, the ammonia nitrogen reacts with nitrifying bacteria and / or nitrite bacteria to form non-toxic substances such as nitrate nitrogen salts. The water is then pumped from the top of the treatment pond into the aquaculture pond for continued artificial shrimp farming. This realizes the recycling of water between the aquaculture pond and the treatment pond, which not only saves water resources but also greatly reduces production costs, thereby further reducing the selling price and bringing good economic, social and ecological benefits.
[0018] 3. This utility model has a simple structure, significant water-saving effect, low production cost, and is easy to promote and apply. Attached Figure Description
[0019] Figure 1 This is a cross-sectional schematic diagram of the present invention. Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 :
[0021] A factory-scale recirculating aquaculture system for shrimp farming includes a culture pond 10, a treatment pond 20 on one side of the culture pond 10, and the bottoms of the culture pond 10 and the treatment pond 20 connected by a circulation pipe 30. The treatment pond 20 contains a bacterial house 22 occupying 30-70% of its volume. A water pump 34 has an inlet pipe 33 connected to the upper part of the inner cavity of the treatment pond 20 and an outlet pipe 35 connected to the inner cavity of the culture pond 10 (the arrows in the figure represent the water flow direction when the water pump 34 is working). The bacterial house 22 is provided with nitrifying bacteria and / or nitrite-oxidizing bacteria. A first drainage pipe 14 extending outward from the outer side of the culture pond 10 is provided on the inner bottom of the culture pond 10, and a first drainage valve 13 is provided on the first drainage pipe 14.
[0022] As a further optimization of the above technical solution, the inner diameter of the aquaculture pond 10 is 5-15 meters and the inner cavity height is 0.9-1.2 meters, and the inner diameter of the treatment pond 20 is 5-15 meters and the inner cavity height is 0.9-1.2 meters.
[0023] As a further optimization of the above technical solution, the aquaculture pond 10 and the treatment pond 20 are containers with open tops made of cement, metal or plastic materials.
[0024] As a further optimization of the above technical solution, the bacterial house 22 is made of plastic, rubber or other polymer materials.
[0025] As a further optimization of the above technical solution, the inner bottom of the aquaculture pond 10 has a conical surface 12, and the inlet of the first drainage pipe 14 is located at the lowest point of the conical surface 12, so as to facilitate the smooth discharge of all solids and water in the aquaculture pond 10.
[0026] As a further optimization of the above technical solution, the bacterial house 22 is a cuboid with a height of 16cm×4cm×4cm or a cylinder with a height of 16cm and a diameter of 4cm, and the bacterial house 22 is covered with micropores for bacterial reproduction and growth.
[0027] As a further optimization of the above technical solution, a second drainage pipe 24 extending outward from the outer side of the treatment pool 20 is connected to the inner bottom of the treatment pool 20, and a second drainage valve 23 is provided on the second drainage pipe 24.
[0028] The breeding pond 10 and the treatment pond 20 are both installed on the base, which facilitates the installation and control of the second drainage pipe 24 and the second drainage valve 23, the first drainage pipe 14 and the first drainage valve 13; a water valve 31 is connected to the circulation pipe 30.
[0029] As a further optimization of the above technical solution, a support 32 is provided on the top of the treatment pool 20 or the aquaculture pool 10, and the water pump 34 is installed on the support 32.
[0030] As a further optimization of the above technical solution, a filter screen 40 is installed on the inlet of the circulation pipe 30 located in the aquaculture pond. The filter screen 40 can prevent the farmed shrimp from entering the treatment pond 20 from the aquaculture pond 10 through the circulation pipe 30.
[0031] As a further optimization of the above technical solution, the bottom of the treatment tank 20 and / or the aquaculture tank 10 is provided with two or more aeration pipes 51. The aeration pipes 51 are connected to the air outlet of a blower or air pump installed outside the treatment tank 20 and / or the aquaculture tank 10 through an air supply pipe 52. Providing oxygen from the air through the aeration pipes 51 can increase the reproduction rate of bacteria and the oxygen content in the aquaculture tank 10, thereby promoting the healthy growth of shrimp.
[0032] Use of this utility model:
[0033] 1. Close the first drain valve 13 on the aquaculture pond 10 and the second drain valve 23 on the treatment pond 20, open the water valve 31 on the circulation pipe 30, fill the aquaculture pond and treatment pond (the treatment pond contains a bacterial house planted with nitrifying bacteria and / or nitrite-oxidizing bacteria) with water, and put shrimp larvae and shrimp feed into the aquaculture pond to carry out normal aquaculture.
[0034] 2. The water pump is started every 1-24 hours, and each pumping lasts for 1-2 hours. When the pump is working, the water containing ammonia nitrogen in the aquaculture pond flows into the treatment pond through the water valve 31 on the circulation pipe 30 under the action of water level difference. The ammonia nitrogen in the treatment pond reacts with nitrifying bacteria and / or nitrite bacteria in the bacterial house to form non-toxic substances such as nitrate nitrogen salts. The water containing non-toxic substances is pumped into the aquaculture pond for continued artificial shrimp farming, realizing the recycling of water in the aquaculture pond and the treatment pond.
[0035] 3. After a batch of shrimp has grown to adulthood, the breeding pond and treatment pond are cleaned once. The water and solids in the breeding pond and treatment pond are discharged through the first drain valve 13 on the breeding pond 10 and the second drain valve 23 on the treatment pond 20.
[0036] 4. Repeat the above steps to form continuous aquaculture. Since the nitrifying bacteria and / or nitrite bacteria in the bacterial house can be used for a long time by being introduced in sequence, only the electricity cost of the water pump is consumed. Compared with the frequent water changes of the existing technology, the production cost of this utility model is relatively small, and the economic, social and ecological benefits are better.
