With the development of metal mining industry, a large amount of heavy metals such as arsenic, lead, zinc, cadmium, copper and the like are discharged into seawater, once the heavy metals are absorbed into a food chain, the heavy metals are finally accumulated in organisms and are finally harmful to the health of human bodies, and the heavy metal pollution of the marine environment, particularly the offshore sea area, is a problem which people must face worldwide. In addition, the mariculture industry in China is developed vigorously, and the mariculture industry is gradually transited from the original scattered free-ranging to intensive cage culture. The change of the breeding mode plays a very positive role in the economic development of the breeding industry; meanwhile, the residual bait amount and the excretion amount of the cultivated animals are increased due to high cultivation density and large bait feeding amount, and the residual bait and the excretion of the cultivated animals become important pollution sources of seawater besides land source pollution. However, large-sized seaweeds (such as kelp, sargassum thunbergii and the like) which are common in coastal areas of China have the capability of adsorbing heavy metals such as arsenic, zinc, cadmium and the like due to the fact that the seaweeds are long and grow fast, meanwhile, rich nutrients such as ammonia nitrogen, nitrite nitrogen, phosphate and the like in seawater can be purified, and the sea water purification device is very suitable for purifying seawater. Therefore, the biological repair of the seawater can become one of effective ways for improving the seawater pollution by cultivating the large-scale kelp in a large scale.
