Embodiment 1

[0037] Such as figure 1 and figure 2 As shown, a water treatment device for a circulating aquaculture system is structured as a closed box, and the interior of the box is divided into two chambers, the ultraviolet radiation area and the biological filler reaction area, by a vertical partition, and the lower end of the partition is Fixed on the bottom plate, the distance between the top of the partition and the top of the box is 5-10cm. The ultraviolet radiation area and the biological filler reaction area are only communicated through the gap between the top of the partition and the top of the box.

[0038] The tubular static mixer 3 is arranged on the side away from the partition in the ultraviolet radiation area, the top is the water inlet 101 and the ozone air inlet 102, fixed on the top of the box, and the bottom is the outlet, leaving a distance from the bottom of the box. The distance between the outlet of the static mixer and the bottom of the box is 10% to 20% of th...

Abstract

The invention relates to a treatment process and device for aquaculture and disinfection and organic removal of circulating cultivation water. The device adopts a static mixer for mixing ozone and is mainly used for sterilization, and the loss of pressure head of the static mixer is less; after being treated in an ultraviolet radiation area, the cultivation water is sterilized and organics are removed, and then the cultivation water enters a biological stuffing reaction area for mainly removing organics. The device integrates ozone dissolution and reaction, has a simple structure, and can be used for sterilizing cultivation water bodies, degrading organics, removing ammonia nitrogen and water color, and increasing dissolved oxygen.

Description

technical field [0001] The invention relates to a treatment process and device for disinfection and removal of organic matter in aquaculture and aquaculture circulating water. Background technique [0002] Recirculating aquaculture is the development trend of aquaculture in the future. However, due to the high density and high load of aquaculture and the high recycling rate of water, it is more difficult to control the water environment; and because of the repeated use of water, if the aquaculture water is brought into If there is no pathogen, the cultured organisms will be in repeated contact with the pathogen for a long time, which will increase the risk of breeding. Therefore, water disinfection and organic matter removal in recirculating aquaculture systems are necessary treatment links. [0003] Ozone is a strong oxidant and disinfectant, which has been proven to quickly and effectively kill viruses, bacteria and protozoa in aquaculture water, and can also oxidize refr...
