摘要:
Using electric power obtained by marine wind force and a tide, sea water is electrolyzed to produce fresh water, sodium, magnesium, calcium, potassium, caustic soda, chlorine, hydrochloric acid, sulfuric acid, hydrogen, oxygen or the like, at the same time, unloaded malts, saw dust and the like are fermented to brew ethanol, carbon dioxide generated here is used for photosynthesis to culture vegetables and oxygen generated here is supplied to a fish preserve and an under reef where fish live to culture fishes and also returned to sea water dropped in the concentration of oxygen to suppress the generation of a red tide.

The present invention relates to an aquaponics system and method. There is provided an aquaponics system including a tank (10) for housing at least one aquatic animal species; a plant growing apparatus (18) for housing one or more plant species growing in an aqueous environment; and a biofilter module including a solids removal means (12) and a biological waste digestion unit (14) including a biological species for digesting solids to produce plant nutrients. Plant nutrients are transferred to the plant growing apparatus (18) and at least a portion of the water is returned to the tank (10).
摘要:
A sheet for forming a series of twisted surfaces and a method for producing such a sheet, wherein a large number of curved surfaces are formed such that when sewing threads are pulled so that the sheet material in said region is opened at an incision, said curved surfaces are raised, and inclined in the longitudinal direction of the sewing threads by providing a line or a plurality of lines of wavy seams or network seams by means of the sewing threads and forming the incision in every region of the sheet surrounded by the seams, and provides a member which can be favorably used as a water contacting material in biological water treatment, a material for protecting a slope in civil engineering works, etc.

摘要:
The aim of the present invention is to propose an offshore aquaculture installation in a healthy environment for fish, having the smallest possible impact on the environment in terms of pollution, with a combination of technical means ensuring the stability of the structure and the safety of humans, with all the equipment necessary for easy offshore operation. This aim is achieved by an offshore aquaculture installation comprising one or a plurality of cages (1) for breeding fish and a floating structure (2) that is ballasted and submersible. The installation is characterised in that it comprises a main anchoring device having an anchor line (3) linked on one side (6) of the structure (2) and capable of being anchored on the other side to a single anchoring point (4) in the installation environment, the structure comprising at least two parallel casings (5) containing adjustable ballasts, said casings (5) being installed at the bottom of each of the lateral faces (7) of the structure (2), in that the cage or cages (1) is/are square or rectangular, and in that the upper portion of the installation constitutes a handling bridge providing access to the cages.
