Aeration equipment for prawn raising in rice field

Abstract

The invention discloses aeration equipment for prawn raising in a rice field. The aeration system comprises an aeration device, a solar panel, an aerobiont carrier, a floater, a composite vegetable bacterium control crocodile nozzle plate, an underwater creature carrier and multiple aeration pipes. The floater floats on the water surface, the solar panel, the aeration device and the aerobiont carrier are arranged on the upper surface of the floater, and the solar panel is connected with the aeration device; the underwater creature carrier is arranged below the floater, the aeration pipes are vertically distributed on the peripheries of the floater and the underwater creature carrier, the composite vegetable bacterium control crocodile nozzle plate is arranged between the floater and the underwater creature carrier, the upper portion of the composite vegetable bacterium control crocodile nozzle plate is provided with the aerobiont carrier, and the lower portion of the composite vegetable bacterium control crocodile nozzle plate is provided with the underwater creature carrier. The aeration equipment is simple in structure, low in operation cost and environmentally friendly, saves energy, improves the underwater water quality and has an obvious aeration effect. The aeration equipment carries out deep-layer underwater aeration on a macrobrachium rosenbergii breeding pond by applying solar energy and bioenergy and improves the water quality.

Description

technical field [0001] The invention relates to an aeration device for raising shrimps in paddy fields. Background technique [0002] Dissolved oxygen is one of the important conditions for maintaining the ecological balance of the water environment and the biochemical decomposition of organic matter, and is an important water quality indicator. Aeration and oxygenation technology combines the principle of aeration oxidation pond and oxidation canal, which can accelerate the reoxygenation process of water body in water environment treatment, so that the self-purification process of water body is always in an aerobic state, improve the vitality of aerobic microorganisms, and at the same time charge The dissolved oxygen can quickly oxidize organic matter and substances produced during anaerobic degradation, effectively improve the black and odorous state of the water body, and can enhance the turbulence of the river water body and slow down the release of phosphorus from the s...

AI Technical Summary

Problems solved by technology

[0003] At present, there are three types of aerators that are widely used in production practice: Blast aeration: its disadvantage is that it needs to build a blower room and aeration pipe network, which is costly, unsightly, and inconvenient to install and maintain

Mechanical aeration: its disadvantages are aeration on the water surface, poor oxygenation effect, small service area, and easy damage

Jet aeration: its disadvantages are low efficiency, easy to block, and inconvenient installation and maintenance

The water quality of Macrobrachium rosenbergii culture ponds is generally improved with aerators, but it is difficult for general aerators to treat the lower water quality
