Aquaculture and purification integrated equipment

Abstract

The invention discloses an integrated equipment for aquaculture and purification, which comprises a culture pond with a conical bottom; a biological bag with a closed cavity filled with biological filter material, an automatic air pressure regulating valve and a water inlet on the top, and a side wall or There is a water outlet pipe at the bottom; the air lift part includes an air supply end, aeration head I, aeration head II and a riser; the upper end of the riser extends into the water inlet of the biological bag, and the lower part is formed to be suitable for the aeration head Ⅰ and the shape of the aeration head Ⅱ placed inside; and the sedimentation part, including the drainage pipe and the slope variable diameter sedimentation pipe. This equipment achieves the required concentration of dissolved oxygen in the breeding pond, and does not require additional equipment and power to circulate the water body, and can collect residual bait feces and purify water quality. Because there is no direct aeration at the bottom of the breeding pond, the water flow is not disturbed. Residual bait feces and suspended solids are easily deposited to the bottom of the pool and discharged with the water flow, which is convenient for cleaning and shortens the time for water quality deterioration.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to integrated equipment for aquaculture and water purification. Background technique [0002] At present, in the traditional industrialized aquaculture production process, in order to supply the oxygen in the water body in the pond body, the method of oxygenation and aeration is mostly used, and the air pipe placed on the upper part of the aquaculture pond is divided into thin tubes to supply air to each pond body . The entire breeding water surface is aerated in many places, and the broken air bubbles on the water surface increase the air-water interface, resulting in high humidity in the breeding workshop. At the same time, this is also an important aspect that causes heat loss. In high-density breeding, pure oxygen aeration can improve the efficiency of oxygen supply, but the preparation, transportation and storage of liquid oxygen, liquid oxygen tanks, and decompression re...

Problems solved by technology

On the one hand, this large-scale circulation route requires electricity to provide circulation power, and on the other hand, it needs to consume more energy to maintain a constant water temperature

Project construction investment is high, and it is not conducive to energy saving
