Problems solved by technology

[0003] The technical problem that the present invention actually needs to solve is: aquaculture pond, especially the aquaculture pond based on greenhouse cultivation condition, the temperature difference inside and outside the shed is big, can't change water in a large amount according to conventional cultivation method, and pond water has no self-purification ability, meanwhile, plastic film The thermal insulation greenhouse blocks the direct sunlight and the natural exchange of air, weakens the oxidation ability of the pond water body and the decomposition ability of organic matter, which can easily cause the accumulation and concentration of three-state nitrogen to soar, and eventually lead to the deterioration of the aquaculture water body and the loss of production

Embodiment Construction

[0038] The present invention will be further described below in conjunction with specific examples.

[0039] as attached Figure 9-10 As shown, a large-span flexible plastic film insulation greenhouse is installed on the ridge of the pond. Such as Figure 2-3 As shown, an air compressor 1 is set on the pond ridge of the pond, and the exhaust port of the compressor is communicated with the air pipe 2, and the air pipe 2 extends to the bottom of the pond, and the air pipe 2 at the bottom of the pond is equidistantly arranged The air outlet terminal of the outlet pipe 2 is provided with a microporous aeration plate 3 on the air outlet terminal on the fork road of part of the air outlet pipe 2, and high-pressure air is sprayed into the water from the small holes of the microporous aeration plate 3 to increase oxygen in the pond water.

[0040] Set the air intake hoses for the rest of the air outlet terminals, the other end of the air intake hoses is connected to the aeration san...

Abstract

The invention relates to an aquaculture pond water circulating treatment system under heat-preserving greenhouse conditions and a construction method thereof, belonging to the technical field of aquaculture. The aquaculture pond water circulating treatment system under heat-preserving greenhouse conditions is characterized in that the system comprises floating-type bio-filters which float on the surface of water, each floating-type bio-filter comprises a water lifting pipe which is vertically arranged in the center, the water lifting pipe penetrates through a biological felt chamber, a first water overflow fence is circumferentially arranged at the lower part of the biological felt chamber, a biological filtering material chamber is additionally arranged on the external side of the biological felt chamber, a second water overflow fence is circumferentially arranged at the upper part of the biological filtering material chamber, and the floating-type bio-filters are transversely fixed and can move vertically along with water level; partial or all air outlet terminals are connected with the lower ends of air inlet pipes, the upper ends of the air inlet pipes are communicated with the water lifting pipes, and aeration sandstones are additionally arranged in the water lifting pipes; and water enters the floating-type bio-filters from the water lifting pipes, the filtered water overflows from the second water overflow fences which are circumferentially arranged at the upper parts of the biological filtering material chambers and finally the water enters an aquaculture pond.

Description

technical field [0001] The invention relates to an aquaculture pond water circulation treatment system and a construction method thereof under the condition of a thermal insulation greenhouse, and belongs to the technical field of aquaculture. Background technique [0002] At present, in pond aquaculture production, especially in shrimp aquaculture production, in order to prolong the production season and change one crop into two crops to increase aquaculture production, the technology of covering aquaculture ponds with large-span flexible plastic film insulation greenhouses is widely used. Although the simple use of heat preservation greenhouses achieves the effect of heat preservation and temperature rise and prolongs the production season, there are many problems that follow. At the same time, the plastic film insulation greenhouse blocks the direct sunlight and the natural exchange of air, which weakens the oxidation ability of the pond water and the decomposition abilit...
