With the development of the domestic economic level, the demand of seafood consumption is increased explosively. In the seafood consumption market, the price of live seafood is far higher than that of frozen products. After the live seafood is caught and fished, temporary culture is needed during waiting for sale. However, the cultivation density of the seafood which is artificially cultivated or harvested from the sea is very high in the transportation and temporary cultivation processes. In this case, a large amount of the excrement of the living seafood, including some soluble excrement such as ammonia, nitrite and the like, can be rapidly accumulated. These substances can reduce the oxygen absorption capacity of live seafood, which can lead to live seafood poisoning. In addition, due to the excessive density of temporary culture, the dissolved oxygen in water can be rapidly consumed, and the living seafood can die in a short time due to oxygen deficiency. In addition, in the process of fishing and transferring the live seafood, the condition of injuries such as scale falling, leg breakage and the like is difficult to avoid, the resistance of the live seafood is reduced in a high-density water body environment, and the wounds are easily infected by pathogenic microorganisms such as bacteria, viruses and the like in water to cause death. Therefore, the circulating water treatment equipment is required to be used for continuously treating the water body in the temporary culture process, so that organic matters in the water body are separated from the water as soon as possible, pathogenic microorganisms in the water body are killed, soluble toxic substances are removed, and the water is kept to have enough dissolved oxygen degree, thereby achieving the purpose of effectively improving the long-term survival rate of the live seafood.
The existing temporary seafood breeding system usually adopts some simple materials such as filter cotton, coral sand and active carbon to simply filter and adsorb temporary breeding water. The method has low cost, but because the breeding density of temporary seafood breeding is high, the materials are easily blocked by organic matters in a short time, the effect of water treatment is greatly reduced, and even the effects of filtering and culturing biological bacteria cannot be achieved. For example, activated carbon can be supersaturated soon and no longer has adsorption capacity, and frequent replacement of the filter adsorbent material can result in a substantial increase in cost, especially when the system is required to operate for a long period of time.

Ozone dissolved in water can react with some soluble toxic substances, part of ammonia is contained in the excrement of the seafood, and part of organic excrement can be decomposed into nitrite, and the substances can generate fatal toxicity to the living seafood. The ozone can oxidize the harmful substances to generate substances, such as nitrate, which are non-toxic to the live seafood, and can effectively reduce the risk of poisoning and death of the live seafood due to the accumulation of the harmful substances. Chemical Oxygen Demand (COD) refers to the amount of oxygen consumed by the chemical oxidation of the oxidizable substances in the water. Ozone reduces COD in water and reduces the probability of seafood oxygen deficiency death caused by overhigh COD. Meanwhile, the water quality of the temporary seafood culture can be clear, and the appearance of customers in the process of selecting the seafood is facilitated. The residual ozone can be rapidly decomposed in water, and the only product after decomposition is pure oxygen, so that the dissolved oxygen degree in water can be further increased.
