Description

TECHNICAL FIELD

[0001] The utility model belongs to the aquaculture technical field, concretely relates to a water quality purification device suitable for the cabin culture mode of a culture workship. BACKGROUND

[0002] Deep sea areas have the advantages of rich fishery resources, high-quality water, suitable water temperature, and being far away from land-based pollution and diseases, and have excellent conditions for carrying out large-scale marine aquaculture and logistics processing and supply, and are a new space for developing modern aquaculture and marine economy.

[0003] A culture workship is one of the core equipment for developing deep-sea aquaculture engineering. The culture workship can reach deep-sea areas that ordinary culture net cages cannot reach, and has high economic value and social value. The culture workship is internally provided with a plurality of large culture cabins. The culture cabins are in the shape of a wide-mouthed bottle, and the cross section of the cabin is in an octagonal structure. The water in the cabin is exchanged with external seawater through a circulating water pump. The water depth in each culture cabin can reach 15 m, and the weight of the reared fish can reach more than 100 tons. The use of the culture workship for fish culture can greatly improve the yield of fish.

[0004] Under the cabin culture mode of the culture workship, the water exchange amount is greatly reduced compared with net cage culture. Therefore, suspended solids, bacteria, and the like in the cabin are not easily discharged outside the cabin through water exchange, greatly affecting the water environment in the culture cabin and endangering the health of the cultured fish.

[0005] Patent CN202221796681.3 discloses a culture workship circulating water treatment system, which comprises a grid, a sodium hypochlorite generator for generating a sodium hypochlorite solution, a seawater booster pump for boosting the seawater after disinfection, a cyclone sand remover, a sand filter, an automatic backwashing filter, an activated carbon filter, and an ultrafiltration membrane filter. The seawater passes through the grid to intercept large substances, the sodium hypochlorite generator is used to kill microorganisms, bacteria, viruses, and the like in the seawater, the cyclone sand remover removes fish, mud, and the like, the sand filter removes most of the suspended solids, the automatic backwashing filter removes the remaining suspended particles, the activated carbon filter intercepts macromolecular organic matter, colloids, residual chlorine, carbon dioxide, hydrogen sulfide, viruses, and heavy metal ions, and the ultrafiltration membrane filter further intercepts the remaining viruses, colloids, proteins, and large organic molecules in the seawater. After the above filtration process, high-quality seawater is provided for the culture cabin, which is beneficial to the growth of fish in the culture cabin. The patent can prevent harmful bacteria in natural seawater from entering the culture cabin and purify the circulating water inlet, thereby providing better water quality for the culture of fish in the workship. However, the overall equipment is expensive, is inconvenient to install and maintain in the culture workship, and cannot solve the problem of harmful substances such as suspended solids and bacteria breeding in the seawater in the culture cabin during the culture process.
