Description

Oxygenation, flow, and filtration circulating water system for aquaculture ponds

The present invention relates to a system for aeration, flow generation and filtration of circulating water in aquaculture ponds, mainly referring to a system that can provide aeration, flow generation and filtration in aquaculture ponds.

Natural aquatic resources are becoming increasingly scarce due to overfishing, so the aquaculture industry can supplement people's demand for aquatic products, and because aquatic organisms are quite sensitive to the living environment, the water quality, pH, dissolved oxygen, and temperature of the aquaculture pond can affect the growth of aquatic organisms. and survival.

For example, the excrement or residual bait of aquatic products will produce harmful substances such as ammonia, NH3, etc., which will affect the water quality and endanger the survival of aquatic organisms. In addition, because the breeding pond is generally a closed water body without water flow and its oxygen content is low, a waterwheel is generally installed above the breeding pond. And through the blades of the waterwheel, the air is injected into the water body to increase the oxygen content of the water body.

However, the waterwheel blades can only pump oxygen into the surface of the water body, and the amount of dissolved oxygen below the water body is still insufficient, which is not conducive to the survival of benthic organisms.

The purpose of the present invention is to provide a circulation system that can provide oxygenation, flow making and filtration in aquaculture ponds.

The circulating water system of the present invention includes an introduction unit, a filter unit, an outlet unit, and a pump. The introduction unit has an introduction pipe and a partition net.

In one embodiment of the present invention, the filter unit is arranged outside the culture tank; and the filter tank of the filter unit can accommodate physical filter materials, chemical filter materials, and biological filter materials.

The present invention enables the water in the culture pond to enter the filter tank of the filter unit during the pumping action, and the screen at the inlet end of the introduction pipe can prevent the cultured organisms in the culture tank from being sucked into the introduction pipe, and the water entering the filter tank can be physically The biological filter material and the chemical filter material filter impurities in the water, and the biological filter material decomposes harmful substances such as ammonia and nitrogen, and then is exported to the breeding pond through the outlet pipe to generate water flow at the same time, and the high flow pressure of the venturi section of the outlet pipe can make the intake pipe Introducing the outside air to mix with the filtered water to generate tiny air bubbles and then enter the aquaculture pond, which can increase the dissolved oxygen in the aquaculture pond and improve the effect of a better living environment for aquatic organisms in the aquaculture pond.
