Container module ecological recycling aquaculture system

The container module eco-circulating aquaculture system is an aquaculture equipment, in particular, the advantage of the narrow length and height of the container itself is realized, and a water-conducting flow is formed by using only the physical characteristics of the water itself without using a water pump operation. Container module ecological cycle aquaculture system with high and low flow, fast flow rate and low energy consumption.

Traditional aquaculture is generally in the soil ponds, but there are many problems, such as sediment pollution at the bottom of the pond, large land occupation, low breeding density, and natural environment.

At present, the more advanced farming methods are fish ponds made of concrete, brick or glass reinforced plastic. Compared with traditional soil pond culture, they not only occupy less land, but also are not affected by the natural environment, and have better control over the breeding environment and water quality. Therefore, the breeding density can be increased.

However, these farming systems generally use multiple pumps to control the flow of water, which requires a certain amount of energy; in addition, the bottom of the fish pond is generally inclined downward toward the central portion, and the sewage outlet is located at the center of the bottom of the pool, tangentially entering the water along the periphery of the pool. The pool water is tangentially flowed and rotated, so that the aquatic excrement and residual bait are discharged from the central sewage outlet; if the water flow in the fish pond is accelerated, the physical reaction of the gravity suction forms a vortex, which is not only unfavorable for swimming of aquatic products. And the sewage is not thorough enough. The bottom of the pool often accumulates dirt and affects water quality.

In addition, general factory farming requires a large investment in plant and civil construction, resulting in high cost and low efficiency, and finally it is difficult to achieve industrialization.

Operation mode of container module ecological recycling aquaculture system

1. The water and aquatic products are first placed in the culture unit. Since the water level of the physical filter unit that communicates with the culture unit through the bottom of the first straight water pipe is lower than the water level of the culture unit, according to the principle of leveling the liquid level in the communicating device at the bottom. In the inner wall of the culture unit, the water absorption micropores form a suction force due to the negative pressure physical law, and the water in the culture unit is sucked into the drainage unit of the culture unit together with the aquatic excrement and residual bait, and passes through the first straight direction. The water pipe is automatically diverted to the physical filter unit; the sewage flows through the multi-layer filter layer, and the filtered dirt is deposited in the sedimentation tank and discharged through the physical filter unit drain pipe at the bottom of the sedimentation tank; the water filtered by the physical filtration unit is in the physical The upper part of the filter unit is diverted to the biological filtration unit via the second straight water pipe.

Benefits of container module ecological recycling aquaculture system

1. The aquaculture system utilizes the weight of the water body and its own physical characteristics to divert the water without the need to install a water pump, so it has the advantage of low energy consumption; the whole system focuses on water flow design, with few mechanical parts and low maintenance cost.

2. The water flow in the culture unit of the aquaculture system rotates up and down for a long time to form a torrent, and the vortex does not occur when the water flow is accelerated. It is not only suitable for long water production, but also makes the distribution of the bait more even, avoiding aquatic excrement and residue. The bait is left at the bottom of the tank. Since the flow rate is doubled compared with the general circulation system, it can ensure complete sewage discharge and improve the water quality in the culture unit. The aeration pipe in the culture unit can also control the oxygen to the water body to maintain sufficient water in the culture unit. The dissolved oxygen level can achieve high density and low energy consumption in aquaculture.

3. The aquaculture system is modified by the conditions of the container itself, which is convenient to assemble, convenient to transport, and internationally versatile. It can expand the module and increase the breeding unit. Both the physical filter unit and the biofilter unit are rectangular boxes for full space. Saves 23% of application space compared to round water.
