Integrated processes for seawater treatment and reuse in marine crops, including filtration, photocatalytic oxidation and biofiltration

摘要

Sea water treatment to increase biomass and survival of marine crop species, including the following stages:a. For crops with planting density of more than 250 people per cubic meter, the individual adapts to the salinity of 5-25 actual salinity units (UPS);b. Through a series of three filters with different particle diameters ranging from 1 to 20 mm, the water of (a) level culture is filtered;c. Photocatalytic water oxidation from grade (b) by using a tube concentric reaction system supporting an ultraviolet lamp;d. An active catalyst is added under the ultraviolet light to support in the ultraviolet concentric nuclear reactor;e. The photocatalytic oxidation of water obtained by (d) stage uses a plate reactor system composed of sulfur and oxygen as a kind of cloth supporting catalyst with bright power; andf. Pass the water obtained in level (E) through the biofilter system.
