Description

Technical Field

[0001] This invention relates to the field of fish breeding station technology, specifically to a controllable ecological aquaculture system and method for a racetrack-type breeding station. Background Technology

[0002] Traditional fish farming often faces problems such as low density, water waste, and environmental pollution. While ecological aquaculture offers a solution, existing systems still need improvement in space utilization, water treatment, and recycling, affecting farming efficiency and environmental friendliness. Chinese patent CN108244020A proposes a support-supported racetrack-style aquaculture pond and a land-based controlled recirculating aquaculture system, using steel pipe supports and PVC mesh fabric to construct the aquaculture chamber, with baffles to optimize water flow. However, this system still suffers from problems such as complex and inefficient water treatment, water waste, environmental pollution, insufficient intelligence, unreal-time water quality monitoring and adjustment, unstable farming environment, and low area utilization efficiency due to planar farming, resulting in low yield per unit area. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a controllable ecological aquaculture system and method for racetrack-type aquaculture stations.

[0004] The technical solution adopted in this invention is as follows:

[0005] A controllable ecological aquaculture system for a racetrack-type aquaculture station includes a three-dimensional vertically arranged ecological aquaculture system. The ecological aquaculture system includes a racetrack aquaculture pond at the bottom, a high-level aquaculture pond at the top, a wastewater treatment pond on the side, and a high-level water quality control pond bridging the high-level aquaculture pond and the wastewater treatment pond. Wherein:

[0006] The raceway aquaculture pond is arranged in a ring shape, including a ring-shaped circulating baffle pool and several aquaculture units located within the circulating baffle pool. All aquaculture units are connected to the circulating baffle pool.

[0007] The high-level breeding pond is arranged in a matrix, including the breeding unit at the highest point and the transition units arranged in a matrix below the breeding unit; one end of the transition unit is connected to the breeding unit, and the other end of the transition unit is connected to the aquaculture unit.

[0008] The high-level water quality control tank is arched and includes a control tank and a water pool regulating tank. One side of the control tank is connected to the sewage treatment tank through an inlet pipe and an outlet pipe, and the other side of the control tank is connected to the high-level aquaculture tank through the water pool regulating tank.

[0009] The wastewater treatment ponds are arranged in a staggered manner, including a central water storage pond, multi-stage biological ponds extending outwards from both sides of the water storage pond, and microfilters located at the edges of the multi-stage biological ponds; the water storage pond contains clean water and is connected to the inlet pipe of the control tank; the multi-stage biological ponds contain wastewater and are connected to the outlet pipe of the control tank.

[0010] This technical solution achieves a three-dimensional vertical layout of the aquaculture space, including raceway aquaculture ponds, elevated propagation ponds, wastewater treatment ponds, and elevated water quality control ponds, to improve aquaculture efficiency and water quality management. Specifically, the three-dimensional layout maximizes the use of aquaculture space and increases aquaculture efficiency per unit area; the layout of the bottom raceway aquaculture ponds, top elevated propagation ponds, side wastewater treatment ponds, and elevated water quality control ponds considers both aquaculture needs and the convenience of water treatment and recycling; the annular circulating baffle pool allows water to circulate between aquaculture units, which is conducive to the even distribution of nutrients and oxygen, while reducing dead zones and improving aquaculture efficiency; the transition units are arranged in a matrix to achieve zoned aquaculture of fish at different growth stages, facilitating management and monitoring; the circulating baffle pool provides a continuous and stable water flow to the aquaculture units through its internal circulation, contributing to the even distribution of fish growth; precise water quality control is achieved through control tanks and water conditioning ponds; the control tanks, as the central hub for water quality regulation, are connected to the water supply system via inlet and outlet pipes. The wastewater treatment ponds are interconnected to treat wastewater and replenish clean water. The equalization pond adjusts water quality parameters, such as pH and dissolved oxygen, based on water quality monitoring results to meet the needs of fish at different growth stages. The multi-stage biological pond utilizes a biofilm to remove pollutants such as organic matter, nitrogen, and phosphorus from the wastewater through microbial degradation. The microfiltration unit removes suspended solids and impurities, improving the quality of the effluent. The breeding units, transition units, and raceway breeding units in the high-level breeding pond provide management for different stages of fish growth. This phased breeding model helps optimize resource allocation and improve breeding efficiency. The clean water treated by the multi-stage biological ponds and microfiltration unit is reinjected into the storage tank for replenishment or circulation in the raceway breeding pond and high-level breeding pond. This recycling model saves water resources and reduces environmental pollution.

[0011] In addition, the controllable ecological aquaculture system for racetrack-type propagation stations proposed according to the present invention also has the following additional technical features:

[0014] According to one embodiment of the present invention, the circulating baffle tank is connected to the outlet pipe of the control tank via a sewage pump.

[0015] This technical solution connects a circulating baffle tank with a sewage pump to achieve the effective collection and transportation of aquaculture wastewater to a water quality control system, providing conditions for subsequent wastewater treatment.

[0016] According to one embodiment of the present invention, the circulating baffle pools surround the perimeter of the aquaculture pool and the central channel; the central channel is provided with a propagation unit and a transition unit.

[0023] This technical solution connects a PLC controller with sensors and a dosing tank to achieve real-time monitoring and intelligent adjustment of aquaculture water quality information, thereby improving the accuracy and automation level of water quality management.

[0024] According to one embodiment of the present invention, the multi-stage biological tank is staggered with high sides and low middle; the sewage flowing into the circulating baffle tank is first pumped to the microfilter for impurity filtration through the outlet pipe, then filtered through the biofilm in the multi-stage biological tank, and finally flows to the low-lying water storage tank.

[0025] This technical solution achieves effective biological treatment and purification of aquaculture wastewater through the staggered arrangement of multi-stage biological tanks and the design of the wastewater treatment process, thus ensuring the sustainable operation of the aquaculture system.

[0026] According to one embodiment of the present invention, the microfilter is located on both sides of the sewage treatment tank, and the bottom of the microfilter is conveyed to the transport vehicle via a track.
