Aquaculture water circulation purification method and device

Abstract

The invention discloses an aquaculture water circulation purification method. The method comprises the following steps: by utilizing a circulating water pump, pumping aquaculture water in an aquaculture pond into a protein separator to carry out protein separation, wherein the ozone accounting for 20% to 30% of the total required ozone quantity is added when the water is pumped into the protein separator; enabling the aquaculture water treated by the protein separator to overflow into a biological mechanical filter to carry out mechanical filtration and biological decomposition; enabling the aquaculture water filtered by the biological mechanical filter to overflow into a disinfection treater to carry out secondary ozone treatment, wherein the ozone accounting for 70% to 80% of the total required ozone quantity is added when the water overflows into the disinfection treater; enabling the aquaculture water treated by the disinfection treater to overflow into an aeration tank to remove the ozone and other harmful gas; and enabling the aquaculture water treated by the aeration tank to overflow into the aquaculture pond. The method disclosed by the invention has the advantages of being less in land occupation, small in civil engineering quantity, low in cost and energy-saving as well as environment-friendly. Therefore, the method is suitable for the aquaculture.

Description

technical field [0001] The invention relates to aquaculture technology, more specifically, it relates to a method for circulating and purifying aquaculture water, and the invention also relates to a device for realizing the method. Background technique [0002] The traditional aquatic farming method is an extensive farming method, mainly relying on large-scale aquaculture ponds, which consume a lot of water and waste water, not only consumes a lot of water resources, but also produces a lot of excrement and residual bait during the breeding process. Accumulation in the aquaculture pond will lead to the deterioration of the water quality in the aquaculture pond and seriously reduce the quality and output of aquaculture products. [0003] In order to save water resources and control water quality, recirculating aquaculture is mainly used to replace traditional extensive aquaculture at present, see Figure 6 As shown, it is a schematic diagram of the standard configuration of t...

AI Technical Summary

Problems solved by technology

Although the circulating aquaculture method has the advantages of water saving, environmental protection, controllable water quality, and production not affected by climate conditions, etc., the amount of underground civil engineering is large, the diameter of the water pipeline is large, the cost is high, and it occupies a lot of land and the construction period is long. Long, high cost, many pumping times, no energy saving
