Aquaculture system, in particular aquaculture system with solar energy circulation and filtration.

At present, sewage and excrement treatment in aquaculture systems is still mostly carried out by aquaculture operators using suction equipment for circulation filtration on a regular basis. This is prone to the aquatic animals in the aquaculture system not being able to circulate and filter in time due to unstable water quality, resulting in unnecessary losses for the aquaculture operators.

Preferably, the pump sequentially extracts sewage from the surface layer, the middle layer and the bottom layer when in use.

From the above description, it can be known that the solar energy circulation filtration aquaculture system provided by the present invention has the following effects:

1. The electric energy converted by the solar power supply module 41 is supplied to the solar water wheel 42 and the circulation filter unit 50, so that the solar circulation filtration aquaculture system can be energy self-sufficient, thereby achieving the effect of saving energy.

2. The circulation filter 53 is designed to process the sewage and the aquatic animal excrement respectively through the first filter valve 531 and the second filter valve 532, so as to simplify the circulation filtration process, reduce the placement space required for the circulation filter 53, and further reduce the energy consumption generated by the circulation filter 53.

3. When in use, the pump 511 sequentially extracts sewage from the surface layer 11, the middle layer 12 and the bottom layer 13 to avoid first extracting sewage from the middle layer 12 or the bottom layer 13, causing sewage from the upper layer to flow to the lower layer, thereby reducing the efficiency of the circulation filtration.

1 and 2, the present invention provides a solar energy circulation filtration aquaculture system, which includes a culture tank 10, a control center 20, a water quality monitoring unit 30, a solar unit 40 and a circulation filtration unit 50. The water quality monitoring unit 30 is disposed in the culture tank 10 to monitor the water quality in the culture tank 10 and transmit a water quality data to the control center 20 in real time; the control center 20 determines whether to activate the solar unit 40 and the circulation filtration unit 50 based on the water quality data evaluation; the circulation filtration unit 50 is provided with electric energy for its operation through the solar unit 40.

In this embodiment, the solar energy circulation filtration aquaculture system is cultivated in a fish-vegetable symbiotic manner, which is to combine aquaculture and hydroponic cultivation, use the excrement of aquatic animals to supply nutrients that can be absorbed by hydroponic vegetables (such as water spinach, lettuce, Chinese cabbage, chrysanthemum, etc.), and assist in partial water purification through the root system of the hydroponic vegetables.

The culture tank 10 includes a surface layer 11, a middle layer 12, a bottom layer 13 and a sedimentation layer 14 from the top to the bottom.

In other words, the solar energy power supply module 41 is electrically connected to the solar energy water wheel 42 and the circulation filter unit 50, respectively. Through the rotation of the solar water wheel 42, the contact area between the water in the surface layer 11 and the air and sunlight is increased, thereby increasing the dissolved oxygen content in the water in the surface layer 11 and reducing the total number of bacterial colonies.
