Description

Technical Field

[0001] This invention relates to the field of shrimp pond water treatment technology, and in particular to a greenhouse racetrack-type circulating water treatment device for shrimp ponds. Background Technology

[0002] Shrimp ponds in shrimp farming greenhouses are usually equipped with drainage ditches. However, traditional drainage ditches cannot treat the wastewater. The wastewater, which contains a large amount of suspended solids, particles, organic matter, nitrogen and phosphorus substances, and algae, is discharged directly, causing great pollution to the environment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a greenhouse racetrack-type shrimp pond circulating water treatment device that can effectively treat the tailwater of shrimp ponds.

[0004] To solve the above problems, the present invention proposes the following technical solution: a greenhouse racetrack-type shrimp pond circulating water treatment device, comprising a sedimentation tank, a filtration tank, a biological adsorption tank, and a biodegradation tank. A brush is suspended in the sedimentation tank, biological filter cotton is suspended in the filtration tank, adsorption particles and microbial agents are added to the biological adsorption tank, a water outlet is provided at one end of the biological adsorption tank, aquatic plants are planted in the biodegradation tank, and filter-feeding aquatic animals are cultured in the biodegradation tank. The sedimentation tank, filtration tank, and biological adsorption tank are all located at the top of the biodegradation tank.

[0005] As an improvement, the adsorbent particles include plastic particles and ceramic particles.

[0006] As an improvement, the microbial preparation is a Bacillus microbial preparation.

[0007] As an improvement, a water pump is provided in the biodegradation tank, and the water pump is connected to a water pipe inserted into the biodegradation tank.

[0008] As an improvement, the sedimentation tank, filtration tank, and biological adsorption tank are integrated into one unit.

[0009] The beneficial effects of this invention are as follows: This invention adopts scientific regional planning, upgrading traditional drainage ditches into internal circulation water treatment systems. It utilizes the technical characteristics of "three ponds and one wetland" to treat aquaculture wastewater in a contiguous area. Shrimp pond wastewater is introduced into sedimentation tanks by gravity, where it undergoes sedimentation treatment. Suspended solids in the wastewater are settled to the bottom of the tank using brushes. After sedimentation, the wastewater enters a filtration tank, where biological filter cotton removes water particles. After filtration, the wastewater enters a biological adsorption tank, where the addition of Bacillus microbial agents further accelerates the decomposition of organic matter in the water. Finally, it enters a biodegradation tank, where aquatic plants absorb and utilize nitrogen and phosphorus substances in the water, and filter-feeding aquatic animals remove algae. This model significantly reduces the nitrogen and phosphorus content in the wastewater, reduces agricultural non-point source pollution, effectively improves the aquaculture environment, and forces the transformation and upgrading of the fishery industry through water management. It aims to build a modern fishery industry system that is highly efficient, produces safe products, conserves resources, and is environmentally friendly, achieving comprehensive water management and building a beautiful fishery.

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0014] A greenhouse-style racetrack-type shrimp pond circulating water treatment device includes a sedimentation tank 1, a filtration tank 2, a biological adsorption tank 3, and a biodegradation tank 4. A brush is installed inside the sedimentation tank 1, biological filter cotton is installed inside the filtration tank 2, and adsorption particles and Bacillus microbial agents are added to the biological adsorption tank 3. The adsorption particles include plastic particles and ceramic particles. A water inlet 7 is provided at one end of the biological adsorption tank 3. Aquatic plants are planted in the biodegradation tank 4, and filter-feeding aquatic animals are cultured in the biodegradation tank 4. The sedimentation tank 1, filtration tank 2, and biological adsorption tank 3 are integrated into a single unit, all located at the top of the biodegradation tank 4. A water pump 6 is installed inside the biodegradation tank 4, and the water pump 6 is connected to a water pipe 5 inserted into the biodegradation tank 4.

[0015] Working principle:

[0016] This invention utilizes a "three-pond-one-wetland" technical approach to treat aquaculture wastewater in a contiguous manner. Wastewater from the shrimp ponds is introduced into sedimentation tank 1 by gravity, where it undergoes sedimentation. Hanging brushes provide surface area for microorganisms in the wastewater, causing them to form flocs that adhere to the brushes. The brushes then cause suspended solids in the wastewater to settle to the bottom of the tank. After sedimentation, the wastewater enters filtration tank 2, where biological filter cotton removes water particles. Following filtration, the wastewater enters biological adsorption tank 3, where adsorption particles adsorb organic matter from the wastewater. The addition of Bacillus microbial agents further accelerates the decomposition of organic matter in the water. The water finally enters the biodegradation tank 4, where aquatic plants absorb and utilize nitrogen and phosphorus from the water, and filter-feeding aquatic animals remove algae. Water pump 6 and water pipe 5 work together to pump water from the biodegradation tank 4 into the shrimp farming water, creating a pressure difference and promoting the circulation of the tailwater. This model greatly reduces the content of nitrogen and phosphorus in the tailwater, reduces agricultural non-point source pollution, and effectively improves the farming environment. By controlling water pollution, it forces the transformation and upgrading of the fishery industry, builds a modern fishery industry system that is highly efficient, safe in products, resource-saving, and environmentally friendly, achieves comprehensive water management, and builds a beautiful fishery.

[0017] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
