Description

The invention relates to an aquaculture system with the features in the preamble of the independent main device claims.

An aquaculture system and cultivation process for the rearing of aquatic organisms, in particular fish, is from the DE 20 2014 103 397 U1 known. The aquaculture system has a culture container with culture water for aquatic organisms, a container for rearing feed animals, in particular marine worms, a container for rearing plants, an algae reactor with algae, in particular an algae suspension, and a fluid connection with a circuit for the culture water that connects the containers on.

the WO 2019/106125 A1 shows a further aquaculture system together with a cultivation process with at least one additional storage container for the culture water. It enables a separate and independently scalable production of algae, of feed animals, in particular marine worms, and of plants, in particular in each case identical or different species.

Another aquaculture facility with vegetable fish feed and a wastewater treatment facility for fish manure is from the DE 10 2018 007 939 A1 known.

the WO 2016 161 503 A , US 1,181,391 B1 , U.S. 5,660,140 A and U.S. 5,121,708 A disclose aquaculture facilities with plants and possibly coal mine water.

the EP 1 580 168 A1 concerns the cleaning of aquariums with coal.

the JP 2017-158 435 A teaches coal-based herbivore growth promoters.

It is the object of the present invention to show a further improved aquaculture technique.

The invention solves this problem with the features in the independent main device claims.

The claimed aquaculture technology, i.e. the aquaculture system and the associated cultivation process, have several advantages in terms of function, efficiency, environmental compatibility, sustainability and economic viability.

The aquaculture system can comprise an aquaculture installation and further system components. The other system components increase the sustainability and environmental compatibility of aquaculture technology. The aquaculture technology, in particular the aquaculture system and the breeding process, can be natural, sustainable and residue-free. Other existing structures can be used for the aquaculture system. This can be, for example, the structures and components of an abandoned power plant, preferably a coal-fired power plant. This leads to high synergy effects and enables a new, efficient, environmentally friendly and sustainable raison d'être for coal-fired power plants that were previously emission-critical in the combustion of fossil fuels.

Particular advantages also result from the coupling of aquaculture technology with the recycling of waste, e.g. from agriculture, in particular from the breeding of land animals, and / or from plants and / or from sewage treatment plants.

In a first aspect of the invention, aquaculture technology, in particular the aquaculture system, comprises an aquaculture system for rearing aquatic organisms, in particular fish, and rearing plants with one or more corresponding containers and a fluid connection with a circuit for the culture water. The plants can be used to filter dissolved excretions of the cultivated aquatic organisms in the culture water. The dissolved excrement can contain nutrients for the plants.

In the aquaculture system, in particular in the container for growing plants or at another suitable location, a plant fertilizer is arranged which has coal and, in particular, bound, liquid manure contained therein. The manure can come from agricultural livestock, e.g. pigs and / or cattle. This plant fertilizer can be used for a sustainable and sufficient supply of nutrients to the plants.

The plant fertilizer has the advantage that valuable nitrogen compounds, e.g. nitrates, and other active fertilizers contained in the manure are only gradually released. They may have to be fetched from the plants. Impairment of the circulating culture water and the rearing of aquatic organisms can be avoided. On the other hand, the plant fertilizer is particularly effective and sustainable for the plants. The plant fertilizer may contain other additives, e.g. phosphorus compounds. The plant fertilizer is a system component.

The charcoal contained in the plant fertilizer serves as a humic binding agent. It can be of different origins. It can be, for example, fossil coal, in particular lignite. On the other hand, the coal can be designed as charcoal or as hydrothermal coal, which is obtained from sewage sludge or biomass, for example from plants. The last two types of coal mentioned have the advantage that they are CO2-neutral. For fossil coal, in particular lignite, there is the advantage that this type of coal, previously only used for combustion, can also be used for other environmentally friendly and sustainable purposes. The energy and environmental balance is positive. On the other hand, existing structures, in particular coal mines and coal-fired power stations, can continue to be used and other new and valuable uses can be made.

The aquaculture system can have a coal supply for fossil coal, in particular lignite, or for charcoal as a system component. The coal supply can be designed as a warehouse, a coal mine or in some other way. The aquaculture system can also contain a treatment plant for hydrothermal coal from sewage sludge or from biomass as a system component. The hydrothermal coal can be produced and used on site from sewage sludge or from other, e.g. vegetable, biomass. By-products such as phosphates in the liquid phase and the like can also arise and be used, possibly as further plant fertilizers. The hydrothermal coal can itself contain nutrients for plants and release them to the plants in an environmentally friendly manner and without adversely affecting the culture water cycle.

In addition, there is a favorable energy balance. The sewage sludge can be supplied from sewage treatment plants from the surrounding area in an energy-efficient and cost-effective manner. Others, e.g. vegetable, biomass can be obtained from composting plants etc. There are particular advantages when integrating the aquaculture system and the sewage treatment plants into an industrial and commercial environment.

The aquaculture system can contain a processing device as a system component for the production of said plant fertilizer from coal and liquid manure. This is particularly advantageous in connection with a likewise system-internal coal supply and / or a treatment plant for hydrothermal coal from sewage sludge or biomass. For hydrothermal coal in particular, it can be extracted and reused in the same aquaculture system.

On the other hand, it is possible to produce plant fertilizers from coal and liquid manure in excess and beyond the personal needs for the rearing of aquatic organisms and plants and to sell it to agriculture or other customers. The aquaculture technology claimed can be used beyond its actual purposes for structural improvement in the immediate and wider area.

The aquaculture system and the aquaculture installation according to the first aspect of the invention can contain further components. These can also be included in the culture water cycle. Such a component can, for example, be a container for rearing food animals, in particular marine worms. This container and the farmed food animals can be used as a filter for undissolved particles, e.g. solids, in the culture water, whereby these particles originate e.g. from excretions of the farmed aquatic organisms. Alternatively, instead of the feed animals and a feed animal filter formed therefrom, mechanical filtering or another filter technology can be used for the coarse particles.

The aquaculture system, in particular the aquaculture installation, can alternatively or additionally have an algae reactor with algae, in particular an algae suspension, as a component. The algae can be used to nourish the food animals and possibly also the aquatic organisms.

In a second aspect of the invention, aquaculture technology, in particular the aquaculture system, can have a culture container with culture water and a container for rearing feed animals, in particular marine worms, and a fluid connection with a circuit for the culture water for the rearing of aquatic organisms. The feed animals can be used to feed the aquatic organisms that have been farmed.

The aquaculture technology, in particular the aquaculture system, can have as a system component a memory with an air conditioning device, in which the eggs of feed animals can be stored and kept in a climate that is not suitable for hatching young animals. Thanks to the air conditioning, the eggs can be kept below the hatching temperature, especially when the temperature is low.

The storage facility with the air conditioning system has the advantage that feed animals can be reared or reared all year round and regardless of the season. The eggs produced by the feed animals can for the most part be removed from the said rearing container or from a breeding container and temporarily stored in the store with the air conditioning device. Young animals can then hatch and grow from the remaining eggs in the rearing container or breeding container. Subsequently, eggs can gradually and in batches be returned from the store to the rearing container or breeding container, where they can be hatched under suitable climatic conditions.

Thanks to the air conditioning, it is possible to temporarily store the living eggs over a longer period of time, so that young animals can hatch over the entire year or at least over a large part of the year. As soon as the young animals are sexually mature and fertilized, there are also new eggs in the container for rearing the food animals, so that the replenishment of young animals can be controlled and the removed food animals can replace those used for rearing the aquatic organisms or for another use, e.g. for Generation of hemoglobin or blood plasma.

A store, possibly with air conditioning, can also be provided for eggs from the aquatic creatures that have been bred and, if necessary, for their offspring.

The aquaculture system, in particular the aquaculture installation, according to the second aspect of the invention can contain one or more further components. These can also be included in the culture water cycle. Such a component can, for example, be a container for growing plants. This can be used as a plant filter of the aforementioned type. Furthermore, an algae reactor with algae, in particular an algae suspension, can be present. The growing container for plants or the plant filter and the algae reactor are advantageous, but not absolutely necessary. A filtering of dissolved excretions of the cultured aquatic organisms in the culture water can also be achieved with another filter technique. Instead of the algae, other biomass obtained from other sources can be used.

Particular advantages result from a combination of aquaculture technology, in particular aquaculture systems, according to the first and second aspect of the invention.

The aquaculture technology, in particular the aquaculture system, can have an additional utilization for feed animals and / or plants and / or algae. This results in an increased economic possibility of use and an improvement in sustainability and environmental support.

Aquaculture technology, in particular the aquaculture system, enables scalable production of feed animals, plants and algae that goes beyond the internal requirements of aquaculture technology for the rearing of aquatic organisms. In particular, plants and algae can be produced in excess and marketed independently. The plant fertilizer based on coal and liquid manure is particularly advantageous for this. Plants and algae can be used as food, as raw materials for the production of cosmetics, medicines and for other purposes. Algae can also be used as fuel. The food animals, in particular the marine worms, can be used for the said production of hemoglobin or blood plasma, as food or as bait or the like.

The aquaculture system can have its own energy supply as a system component. This can, for example, have an energy generator operated with charcoal or hydrothermal coal. This results in a further and system-immanent possibility of using the coal. The CO2 neutrality is also an advantage here. The energy supply can be used to supply a climate hall, the storage facility's climate control system and other consumers within the aquaculture system with energy. Alternatively or additionally, other types of energy can be used, e.g. solar energy, biogas, wind power or the like. The energy supply can have corresponding additional or alternative designs.

Aquaculture technology, especially the aquaculture system, can have its own and new infrastructure. However, it can also be integrated into existing structures, e.g. in an abandoned power plant. A coal-fired power station has particular advantages. Some of the aforementioned system components are already present here. This concerns large containers and fluid connections that can be used for the said rearing of aquatic organisms, plants and feed animals as well as algae. An energy supply and an energy generator are also available. There are also spacious halls for accommodating the said system components. An abandoned power plant, in particular a coal-fired power plant, can thus be put to a new use and does not have to be demolished. An aquaculture system can advantageously be integrated into existing industrial environments and can advantageously use existing resources while maintaining sustainability and environmental compatibility.

The aquaculture installation used in an aquaculture system can be designed in different ways, for example according to FIG WO 2016/012489 A1 or the WO 2019/106125 A1 . The latter has particular advantages for the separate and independently scalable production of algae, feed animals and plants, in particular from the same or different species. One or more additional storage containers for the culture water and adapted fluid connections, in particular with sub-circuits, are advantageous for this.

Further advantageous embodiments of the invention are specified in the subclaims.

The outlay for feeding the reared aquatic organisms, in particular fish, can be significantly reduced by feeding by means of a feed production integrated into the aquaculture system and with the feed animals, in particular marine worms. The water consumption is also very low. A natural feeding cycle for aquatic organisms can be created. There is no need to use other organic feed, in particular fish meal, or antibiotics.

On the one hand, the feed animals absorb the particulate excretions of the aquatic organisms or other undissolved particles in the culture water and can thus fulfill a filter function as a feed animal filter. The feed animals can for their part be fed with these particles as well as with algae, in particular microalgae from an algae reactor. The aquaculture system also has a filter for the excretions of the aquatic organisms dissolved in the culture water. A plant filter is particularly suitable for this.

An additional storage container for the culture water is advantageously arranged in the culture water circuit. The arrangement of this additional storage container enables an optimization of the rearing of aquatic organisms, food animals, plants and algae. The amounts of culture water required for the respective rearing can be made available in sufficient size and separately from one another.

In addition, filter functions for the culture water or the filter circuit can be improved. Particulate excretions from aquatic organisms, in particular fish, can be eaten by the feed animals and can possibly be deposited in their containers. Dissolved excretions from aquatic organisms, especially fish, can be absorbed by the plants and can possibly be deposited in their containers. This multi-stage filter process and the filter circuit with a feed animal filter and a plant filter can be optimized. In particular, the multiple filter functions or filter stages can be controlled separately from one another and independently and as required.

The additional storage container can have a buffer function for the culture water. The supply of culture water to the various containers for said rearing can be controlled as required. The feed quantities to these containers and / or the cycles in the filter stages can be set independently of one another. The additional storage tank enables, in particular, the formation of sub-circuits for the culture water. These can each be independently connected to the additional storage tank for the culture water and can each be controlled independently. The culture water cycle can be subdivided or supplemented by one or more sub-cycles.

The additional storage container can be connected in the filter circuit between the animal feed filter and the plant filter. As a result, the two filters are not directly coupled to one another. The coupling takes place indirectly via the additional storage container. This is where the separately filtered subsets of the culture water come together and mix. The additional storage container can also be connected in parallel in the filter circuit.

The container for growing plants can be independently connected to said storage container with a fluid connection. As a result, an independent sub-cycle can be formed for filtering the dissolved excretions in the culture water.

The container for rearing feed animals can also be independently connected to said storage container with a fluid connection. As a result, an independent sub-cycle can be formed for the supply of the feed animals.

The container for rearing feed animals can be connected on the outlet side via a fluid connection to a fluid inlet of the storage container for the culture water. On the inlet side, the animal feed container can be connected to the culture container and the additional storage container for the culture water. The fluid outlets of the culture container and said storage container can be connected. In this way, a sub-circuit for filtering the particulate excretions can be formed.

In a further aspect of the invention, the algae reactor can be independently connected to the animal feed container with a further sub-circuit. The feed animals can be fed with algae, in particular an algae suspension, from the algae reactor. An additional storage tank for the culture water arranged in the culture water circuit is advantageous, but not absolutely necessary.

In addition to the algae, the feed animals can also be fed nutrients contained in the culture water. An independent feeding circuit is created for the feed animals. This sub-circuit for feeding can, if necessary, be separated from the aforementioned sub-circuit for filtering the particulate excretions. For this purpose, it is also advantageous if at least two groups of each one or more animal feed containers are available.

The culture water can be processed in a suitable and gentle manner. It can be made from fresh water that comes from a well or a water pipe or the like. Preferably only inorganic nutrients, in particular nutrient salts, electrolytes or the like, are added to the fresh water. This allows a pure nutrient solution to be formed. The fresh water can also be subjected to particularly intensive filtering, in particular reverse osmosis and / or ultra-filtration. The storage tank for the culture water can be preceded by one or more additional storage tanks with which the culture water is produced and processed. The water can be fresh water or salt water.

According to a further aspect of the invention, there is a storage container for an optionally saline nutrient solution. An additional storage tank for the culture water arranged in the culture water circuit is advantageous, but not absolutely necessary.

The storage tank for the nutrient solution is e.g. upstream of the storage tank for the culture water. The nutrient solution consisting of fresh water is not yet contaminated with excretions from aquatic organisms. The storage container for the nutrient solution can be independently connected to the plant container via a fluid connection. As a result, another sub-cycle and an independently inventive nutrient cycle can be formed for the plants.

The claimed aquaculture technology enables multiple benefits. In a further aspect of the invention, the rearing of aquatic organisms, feed animals, plants and algae can be quantitatively decoupled from one another and are independently scalable.

The aquaculture system and the method can be provided and designed or used for the separate and independently scalable production of algae, feed animals, in particular marine worms and plants, in particular in each case identical or different species. An additional storage tank for the culture water arranged in the culture water circuit is advantageous, but not absolutely necessary.

In addition to feeding aquatic organisms and filtering particulate excretions, the feed animals can also be used for other purposes. The production quantities or breeding quantities can be selected correspondingly large. The near-natural conditions in the aquaculture facility and the preferred avoidance of the addition of antibiotics and / or organic nutrients, e.g. fish meal, for feeding the farmed aquatic organisms are particularly advantageous for this.

With the aforementioned aquaculture system and the cultivation method, marine worms, in particular lugworms, can be produced naturally and without contamination with antibiotics or other pollutants. The marine worms, especially lugworms, are natural and are particularly suitable as healthy, natural and pure starting material for the production of hemoglobin or blood plasma. The worm production is scalable with the claimed aquaculture technology. It can also be done independently.

In addition to filtering dissolved excretions, the plants can also be produced or bred for consumption or other purposes. The independent sub-cycle and the nutrient cycle with connection to a storage container for a nutrient solution are particularly advantageous for scaling up plant production.

The aquaculture technology can be used for the rearing or fattening of aquatic organisms and feed animals as well as plants and algae. After the harvest, the stock can be renewed by using new aquatic organisms, food animals, algae and plants. One concept of the invention provides for the breeding of aquatic organisms and / or feed animals, in particular marine worms, which can be integrated into the aquaculture system and the cultivation process. A corresponding breeding facility can be available for this. The system component of a store and an air conditioning device for the eggs can be present independently or be assigned to a breeding device.

The breeding facility can be integrated into the cycle of the culture water and / or the nutrient solution. With the breeding device, environmental conditions favorable to reproduction can be created for parent animals of the aquatic creatures and / or forage animals. For this purpose, in particular the climatic conditions, the lighting and the like can be influenced. In particular, natural phenomena, such as a full moon or the like, can be simulated in order to stimulate multiplication or reproduction.

The aquaculture technology can be made independent and largely independent of a permanent external replenishment of young animals through the breeding and the plant's own propagation and reproduction of the aquatic organisms and / or feed animals. At most is the introduction of new parent animals or eggs useful from time to time to refresh the gene pool.

The mentioned own energy supply of aquaculture technology, in particular of the aquaculture system, can e.g. also include a solar system and / or a biogas system, which can be fed e.g. with excess production of algae from the algae reactor. In one version, the energy supply can cover the energy requirements of the entire aquaculture facility and, if necessary, the aquaculture system independently, to the full extent and in continuous operation. It can thus enable plant and system operation in areas without sufficient public energy supply. It is particularly advantageous to use available energy from the environment, e.g. solar radiation, wind or heat. In another version, it is possible to use a fuel-operated power generator that runs continuously or intermittently, e.g. if another energy supply fails, e.g. from a public power grid, or for other reasons. The energy supply can, for example, be designed as an emergency power generator.

A programmable control is also advantageous for the self-sufficient training, in particular in connection with a communication device for remote data transmission. The aforementioned offspring are also useful for independence and self-sufficiency.

Another idea of the invention provides that the aquaculture system is designed as a prefabricated and preferably modular structural and functional unit.

The possibly self-sufficient aquaculture facility can be standardized and, if necessary, provided as a scalable modular system. It can be set up and operated inland and at a great distance from bodies of water, especially from the sea. Food production can be brought close to consumers.

The effort for planning, installing and operating the possibly self-sufficient aquaculture system can be minimized and simplified. The technical requirements for an aquaculture system operator can also be reduced. The programmable control relieves the operator. If necessary, the aquaculture facility can be manufactured and marketed as a ready-to-use unit, e.g. in a franchise system.

Another idea of the invention provides that the aquaculture installation has a surrounding climate hall with a device for climate control.

Within the climatic hall, favorable climatic conditions for the rearing and possibly also the breeding of animals and plants can be created and kept constant. The preferred independent energy supply and its own programmable control are of particular advantage for this.

The containers for the aforementioned rearing and the additional storage containers can each be present individually or several times. The various sub-circuits mentioned above can each have their own pump arrangement.

The respective containers for rearing feed animals and plants can each be present several times. A tower or cascade arrangement is recommended for each of the said containers, with the culture water flowing through the various containers one after the other and by gravity in a cascade. The energy and pumping expenditure can be reduced. In addition, the containers can be stored on a shelf to save space and costs. This also facilitates handling during cultivation and harvesting as well as maintenance.

In the culture container for the aquatic organisms and in the container for rearing food animals, substrate layers on the bottom, in particular layers of sand and / or layers of gravel, are preferably present. In the culture container, these substrate bottoms can accommodate some of the feed animals, which can therefore continue to live in their familiar surroundings and form a long-term and easily accessible source of feed for aquatic organisms, in particular fish or shrimp that are rooting. These containers can have an optimized fluid drain. This can have separate and / or optimized outlet openings for the culture water and / or the substrate. On the one hand, it enables a permanent and at the same time controlled drainage of culture water. On the other hand, it allows the substrate layer and the feed animals contained therein to be removed in a simple manner.

The aquaculture system also has the advantage of a particularly simple, constructive and inexpensive construction and operation. The arrangement of the containers in stacks is advantageous here. The same applies to the preferred vertical structure of the aquaculture system and the placement on a shelf.

If the aquaculture facility is operated with salt water, a sea-like environment with ebb and flow can be simulated for the feed animals and / or the plants by means of a flooding device. In this way, for example, the environmental conditions for saltwater-tolerant plants or halophytes can be optimized. Alternatively or additionally, a continuous flow mode is also possible. This has advantages in particular for scalable plant production and an independent nutrient cycle with a connection to the storage container for a nutrient solution.

Changing water levels with intermittent filling and emptying of the containers for feed animals and / or plants and a simulation of ebb and flow have further advantages. The standing water level for a while leads to a calming and a longer residence time of the culture water, which facilitates and favors the uptake of the particulate excretions and the algae by the feed animals. At low tide, the containers and especially the substrate there can fall dry. The particulate excretions and the algae can settle on or in the substrate, which is also beneficial for the ingestion by the food animals. In addition, the changing water levels or water heights can result in additional filter and rinsing effects in the substrate area, which are advantageous for the filter function. Similar effects and advantages also exist with a plant filter.

Further advantageous refinements of aquaculture technology are specified in the subclaims.

The invention relates to an aquaculture system ( 90 ) with an aquaculture facility ( 1 ) as well as one or more other system components and a cultivation process for aquatic organisms ( 2 ). The invention also relates to several further independent aspects of the invention mentioned below.

The aquaculture facility ( 1 ) can eg according to the WO 2026/012489 A1 or the WO 2019/106125 A1 be trained. It can be used to raise aquatic organisms ( 2 ), of feed animals ( 3 ), especially marine worms, from plants ( 4th ) and possibly used by algae. This is preferably done in connection with different, possibly multiple, containers ( 6th , 6 ' , 22nd , 22 ' , 23 , 27 ) and a preferably common cycle ( 13th ) of culture water ( 5 ). Furthermore, a water supply ( 87 ) with at least one additional storage container ( 54 ) for culture water ( 5 ) can be used. The aquaculture facility ( 1 ) is described and shown below as an example.

1 shows the aquaculture system ( 90 ) with an aquaculture facility ( 1 ) and with other system components. These system components are, for example, a coal ( 80 ) and manure ( 84 ) formed plant fertilizer ( 86 ) and possibly a processing facility ( 85 ) for this plant fertilizer. Other system components can be a processing device ( 85 ) for the plant fertilizer ( 86 ), and / or a coal supply ( 83 ) and / or a processing plant ( 79 ) for hydrothermal coal ( 81 ) be. A system component can also be saved from a memory ( 75 ) for eggs ( 3 " ) of feed animals ( 3 ) are formed. Also a recovery ( 88 ) for aquatic organisms ( 2 ), Feed animals ( 3 ), Plants ( 4th ) and algae can form a system component. The aquaculture system ( 90 ) an energy supply ( 42 ) with a own energy producer ( 77 ) as a system component.

The plant fertilizer ( 86 ) is used to fertilize the in the aquaculture facility ( 1 ) grown plants ( 4th ). The plant fertilizer ( 86 ) is made of coal ( 80 ) and the manure contained therein ( 84 ) educated. The manure ( 84 ) can in the coal ( 80 ) be bound. The coal ( 80 ) and the manure ( 84 ) can be mixed with one another during production in a container, whereby a layering with liquid and solid phases as well as intermediate stages can form in the container. The solid phases can be drawn off and, if necessary, drained, whereby the plant fertilizer ( 86 ) in one for the aquaculture facility ( 1 ) suitable form, for example in granulate form, can be obtained. The production of the plant fertilizer ( 86 ) made of coal ( 80 ) and manure ( 84 ) can, for example, according to the DE 10 2011 120 504 A1 , DE 10 2016 223 352 A1 or DE 10 2017 005 770 A1 take place. The processing plant ( 85 ) can be designed accordingly.

The coal ( 80 ) can e.g. as lignite or charcoal ( 82 ) or as hydrothermal coal ( 81 ) be trained. For lignite or charcoal ( 82 ) a coal supply ( 83 ) in the aquaculture system ( 90 ) must be included. This can be, for example, a coal store, a coal mine or other mining site or the like.

The hydrothermal coal ( 81 ) can be made from sewage sludge ( 78 ) or from biomass ( 78 ' ), especially vegetable waste, can be produced by hydrothermal carbonization, whereby the carbon content of the sewage sludge ( 78 ) or biomass ( 78 ' ) are converted into a lignite-like fuel at high temperatures and under high pressure. The sewage sludge ( 78 ) valuable phosphates are removed in a liquid phase, which can then be processed and used as fertilizer. In hydrothermal coal ( 81 ) phosphorus and nitrogen compounds can be found in sewage sludge ( 78 ) or biomass ( 78 ' ) be included and remain. You can use the plant fertilizer ( 86 ) can be used as fertilizer components.

In the processing plant ( 79 ) for hydrothermal coal ( 81 ) the sewage sludge ( 78 ) or biomass ( 78 ' ) heated in a heat exchanger at a high temperature of, for example, 200 ° C and high pressure of, for example, 20 bar and are converted into a coal sludge by adding a catalyst. This is then cooled again via a further heat exchanger and fed to a press, in which the coal sludge is mechanically dewatered and compressed to such an extent that a lignite-like fuel is produced. The hydrothermal coal ( 81 ) can, for example, according to the DE 10 2012 019 659 A1 , WO 2017/102814 A1 , WO 2019/068717 A1 , DE 10 2008 049 737 A or EP 2 991 934 B1 getting produced.

In the preferred embodiment, lignite or charcoal or hydrothermal coal ( 81 ) from biomass ( 78 ' ) for the extraction of the plant fertilizer ( 86 ) used. The hydrothermal coal ( 81 ) can also be used for thermal combustion in the energy generator ( 77 ) can be used.

With the energy generator ( 77 ) Energy can be obtained in different forms, e.g. thermal energy for heating and / or electrical energy for the operation of electrical devices, e.g. an air conditioning system ( 76 ) for air conditioning the storage tank ( 75 ) for the eggs ( 3 " ).

The memory ( 75 ) can exist independently or can also be part of an institution ( 47 ) for the breeding of feed animals ( 3 ) must be assigned. The memory ( 75 ) has suitable storage means to hold the eggs ( 3 " ) in preferably several separate batches. With the air conditioning ( 76 ) the climate in the storage tank ( 75 ) should be set so that the eggs ( 3 " ) can be stored for a longer period of time without hatching young animals from the eggs. In particular, the temperature in the storage tank ( 75 ) are kept at a value below the hatching temperature. Otherwise the memory ( 75 ) suitable environmental conditions for the eggs ( 3 " ), e.g. with regard to a damp or wet environment, air supply and the like.

The aquaculture system ( 90 ) is in the embodiment of 1 with the aquaculture facility ( 1 ) and with at least some of the other system components in a power plant ( 89 ) arranged. The power plant ( 89 ) can be, for example, an abandoned coal-fired power station, which has large covered halls, large containers and fluid connections, a heating system and the like.

In the hall or halls, the energy supply ( 42 ), especially of the energy producer ( 77 ), an environmental climate that is advantageous for the various cultivars can be created. This applies to the temperature and possibly also the moisture content of the ambient air. The power plant ( 89 ) can have one or more heating systems for fuel, which are used as energy supply ( 42 ) or as an energy producer ( 77 ) can be used. You can use charcoal ( 82 ) and / or with hydrothermal coal ( 81 ) are fired.

The recovery ( 88 ) can be put into the power plant ( 89 ) be integrated or can be arranged externally.

The aquatic creatures ( 2 ) are fish in the preferred embodiment shown, in particular predatory fish, such as sole. These can be saltwater fish or freshwater fish. Alternatively or additionally, the aquatic organisms ( 2 ) Molluscs (Mollusca), e.g. oysters, mussels etc. or crustaceans (Crustacea), e.g. shrimp. The aquaculture facility ( 1 ) is used for the rearing and fattening of such aquatic creatures ( 2 ). The cyclical breeding time for saltwater fish ( 2 ), e.g. sole, is between 1-2 years.

The aquaculture facility ( 1 ) has a culture container ( 6th ), especially fish tank, with culture water ( 5 ) or process water for the absorption of aquatic organisms ( 2 ) on. The culture water ( 5 ) can be salt water or fresh water. In the embodiment shown, salt water is preferred.

As 2 until 4th make clear, the aquaculture facility ( 1 ) except for the culture container ( 6th ) a container ( 22nd ) for feed animals ( 3 ) and a container ( 23 ) for plants ( 4th ) and an algae reactor ( 9 ) exhibit. The containers ( 6th , 22nd , 23 ) and possibly the algae reactor ( 9 ) can be present individually or multiple times. The aquaculture facility ( 1 ) can also be a controller ( 44 ) exhibit. The control ( 44 ) can also be used to control the aquaculture system ( 1 ) and can be used by one or more of the named system components.

With a multiple arrangement of the containers ( 22nd ) for rearing feed animals ( 3 ) a tower or cascade arrangement of the tanks is recommended. The containers ( 23 ) for growing plants ( 4th ) can also have such a tower or cascade arrangement. The containers ( 22nd ) and the containers ( 23 ) are arranged one above the other. They can be arranged in a stack directly one above the other and with mutual contact and support. The following explained 10 until 18th show such an arrangement. Alternatively, the containers ( 22nd , 23 ) be arranged in a tower or shelf directly one above the other and at a mutual distance. A cascade arrangement also includes a terrace arrangement in which the containers ( 22nd , 23 ) are arranged one above the other and at a lateral distance.

The culture water ( 5 ) flows through the various containers ( 22nd , 23 ) in a cascade one after the other and by gravity The energy and pumping expenditure can be reduced. In addition, the containers ( 22nd , 23 ) can be accommodated on a shelf to save space and costs. This also facilitates handling during cultivation and harvesting as well as maintenance.

The containers ( 6th , 22nd , 23 ) and the algae reactor ( 9 ) can be hydraulically connected to each other via a fluid connection ( 12th ) in a water cycle ( 13th ) for the culture water or process water ( 5 ) be connected. 2 until 4th show an example of an arrangement of the containers ( 6th , 22nd , 23 ) and the algae reactor ( 9 ) as well as hydraulic circuit diagrams. The water cycle ( 13th ) of the culture water ( 5 ) can be self-contained. It can also have one or more sub-cycles ( 13a , 13 ', 13 ").

2 and 3 show a first variant of the aquaculture system ( 1 ). The arrangement of the containers ( 6th , 22nd , 23 ) and the algae reactor ( 9 ) as well as the water cycle ( 13th ) for the culture water ( 5 ) can according to the WO 2016/012489 A1 be trained. In 4th is a second, modified variant of the aquaculture system ( 1 ) shown.

Both variants also show several other modifications of the aquaculture system ( 1 ). One or more of the modifications described below can be used in any number and combination in the aquaculture facility ( 1 ) to be available.

The first variant of 2 the modifications are shown schematically. The second variant of 4th shows a possible integration of the modifications into an aquaculture facility ( 1 ).

A modification concerns an offspring ( 2 ' ) of aquatic organisms and / or offspring ( 3 ' ) of feed animals. Another modification includes an arrangement of at least one additional storage container ( 54 , 53 ) for culture water ( 5 ) or a nutrient solution ( 5 ' ). The aquaculture facility ( 1 ) a water supply ( 87 ) with other facilities.

One modification concerns an independent feeding cycle ( 15 ' ) for feed animals ( 3 ). Another modification aims at an independent nutrient cycle ( 15 " ) for plants. A self-sufficient training of the aquaculture facility ( 1 ) is also a modification. A modification concerns the design of the aquaculture facility ( 1 ) as a prefabricated and preferably modular construction and functional unit. Another modification is the aquaculture facility ( 1 ) surrounding climate hall ( 55 ) to watch. Another modification consists in a scalable production of algae, feed animals ( 3 ) and plants. Another modification concerns the natural rearing of marine worms in the aquaculture facility ( 1 ) for the production of hemoglobin or blood plasma.

The culture container ( 6th ) can have any suitable shape and consist of a suitable material, for example plastic or metal, wood or concrete. The culture container ( 6th ) can be open at the top. At the bottom of the culture tank ( 6th ) a substrate layer ( 28 ), e.g. sand, a mixture of coarse-grained perlite with sand, another mixture containing sand or the like. The inlet and outlet ( 33 , 29) for the culture water ( 5 ) are on fluid connections ( 12th ), e.g. closed lines in the form of pipes or hoses. Alternatively, open lines or channels are possible in certain areas.

In 4th , 7th , 8th and 9 is an example of an embodiment of the culture container ( 6th ) and is described below.

Alternatively, the culture container ( 6th ) as an open tank with a bottom drain ( 29 ), e.g. in the form of a siphon, and with an inlet ( 33 ) be designed in the form of an immersed inlet pipe with several outlet openings located at different tank heights. the WO 2016/012489 A1 shows an example of such an embodiment.

The feed animals ( 3 ) are placed in the culture container ( 6th ) and into the culture water there ( 5 ) given. You can float or swim there and be amazed by the aquatic creatures ( 2 ) are eaten. The substrate layer ( 28 ) can also feed animals ( 3 ) contain. Fondling fish ( 2 ) the substrate layer ( 28 ) rummage through and the local food animals ( 3 ) Wolf down. The feed animals that are preferably unmodified in terms of nutrition, especially natural ones ( 3 ) can be fed alive.

As feed animals ( 3 ) For example, marine worms can be used. These include, in particular, bristle worms (Polychaeta), lugworms (Arenicola marina), ring worms (Nereididae) and others. Alternatively or additionally, other types of feed animals ( 3 ) possible.

On a nutritional modification of the feed animals ( 3 ) by comminution, preparation or further processing, in particular extrusion, into fish feed or dry feed can be dispensed with. The diet and diet of aquatic life ( 2 ) can be significantly improved as a result. The mucous layer present in the marine worms mentioned has a particularly beneficial effect on health. Bristle worms, for example, in their natural habitat form an important component in the diet of many commercially usable fish and crustacean species. As such, they contribute to particularly good digestibility and a strengthening of the immune system.

The feed animal production can be integrated into a water cycle ( 13th ) of the culture water ( 5 ) in the aquaculture facility ( 1 ) to get integrated. This can be beneficial for tolerability. The mutual exchange of metabolic products (chemical messengers, amino acids, etc.) through the common culture water has a positive effect on the growth and keeping conditions of aquatic organisms ( 2 ) the end.

The container ( 22nd ) with the feed animals ( 3 ) on the one hand a feed animal filter ( 7th ), especially a worm filter, which removes particulate matter from the culture water ( 5 ) filters. The feed animal filter ( 7th ) is with the culture container ( 6th ) in a filter circuit ( 14th ) of the culture water ( 5 ) tied together. The container ( 22nd ) with the feed animals ( 3 ) points on the ground ( 59 ) also has a substrate layer of the aforementioned type, in particular a sand layer or a sand-containing layer.

The particulate matter can form particulate excretions from aquatic organisms ( 2 ) in the culture container ( 6th ), Leftover feed or other solids. They are fed by the feed animals ( 3 ) and taken from the culture water ( 5 ) removed. The feed animals ( 3 ) can also filter plankton and microorganisms from the culture water. In addition, food intake by the feed animals ( 3 ) from the substrate layer ( 28 ) possible with the help of their jaws. In particular the marine worms ( 3 ) can be fed with these particulate substances. On the other hand, in a substrate layer ( 28 ), especially a layer of sand, of the animal feed filter ( 7th ) further purification processes of the culture water take place, such as nitrogen removal, mineralization, nitrification, denitrification and annamox.

The feed animal filter ( 7th ) and the culture container ( 6th ) are also in a feeding circuit ( 15th ) tied together. The feed animals ( 3 ) serve as live food to nourish aquatic organisms ( 2 ) and are appropriately placed in the culture container ( 6th ) transferred.

The algae reactor ( 9 ) can also be added to the feeding circuit ( 15th ) to be involved. In a modification, the algae reactor ( 9 ) and the container ( 22nd ) with the feed animals ( 3 ) in an independent feeding cycle ( 15 ' ) be connected.

The algae reactor ( 9 ) is preferably designed as a photobioreactor for microalgae cultivation in both variants. In the algae reactor ( 9 ) algae, especially microalgae, are contained in an algae suspension ( 40 ) bred. The algae can be supplied with nutrients and light for photosynthesis. The algae production cycle can take 1 to 2 weeks, for example.

The algae suspension ( 40 ) can feed animals ( 3 ) for their nutrition via the in 2 and 3 shown water cycle ( 13th ) are supplied. The algae suspension ( 40 ) can also be put into the culture container ( 6th ) reach. The feed animals ( 3 ) and the aquatic creatures fed with it ( 2 ) can be nourished in a natural and species-appropriate way using the algae, healthy and without pollutants and inexpensively. If necessary, aquatic organisms ( 2 ) and the feed animals ( 3 ) other and additional feed are fed. With the independent feeding cycle ( 15 ' ) an ingress of algae, especially algae suspension ( 40 ), into the culture container ( 6th ) can be completely or at least largely prevented.

The container ( 23 ) for growing plants ( 4th ) can be used as a filter ( 8th ), especially plant filters for which in the culture water ( 5 ) dissolved excretions of aquatic organisms ( 2 ) act. He can use the feed animal filter ( 7th ) assigned, especially downstream. Some of the containers ( 23 ) can also be used primarily for plant breeding and have less or no filter function.

In 19th until 22nd is a plant filter ( 8th ) shown in two variants. In the container or containers ( 23 ) is the said plant fertilizer ( 86 ) in a suitable form, for example as granules.

The plant filter ( 8th ) has in both variants one or more trough-like containers open at the top ( 23 ) with a fluid inlet ( 33 ) and a fluid drain ( 29 ) on. The plants ( 4th ) are to the respective culture water ( 5 ) customized. In the exemplary embodiment shown, salt-tolerant plants or halophytes, in particular samphire, are used.

The plants ( 4th ) are in the variant of 22nd in a hydroponics ( 35 ) or hydroponics in a container ( 23 ) held. The plants ( 4th ) take root in an inorganic substrate, which is kept in water-permeable plant pots. The plant roots can thus be removed from the culture water ( 5 ) are flowed around. You can use the culture water ( 5 ) contained dissolved excretions as nutrients and purify the water. The plant fertilizer ( 86 ) can be embedded between the substrate or can also form the substrate.

The plants ( 4th ) can be useful and edible plants, e.g. samphire. They are affected by the culture water ( 5 ) dissolved excretions and additionally from plant fertilizer ( 86 ) nourished and can be harvested in due course. Other suitable plants ( 4th ), e.g. vegetable or lettuce plants, are used.

The fluid drain ( 29 ) the plant container ( 23 ) can be used in a similar way to the culture container ( 6th ) and for the animal feed container ( 22nd ) be trained. The training is explained below.

The plant filter ( 8th ) or the container or containers ( 23 ) a flooding device ( 36 ), with which the water level is relative to the plants ( 4th ) can be changed. In this way, alternating ebb and flow can be simulated for salt-tolerant plants, whereby the plants ( 4th ) not or only in the root area and at times completely from culture water ( 5 ) are washed around.

The container or containers ( 22nd ) for rearing feed animals ( 3 ) or the animal feed filter ( 7th ) such a flooding device ( 36 ) exhibit. This allows a sea-like environment with ebb and flow for the feed animals ( 3 ), especially the marine worms, can be simulated. This can prevent the excretions and algae from being absorbed by the feed animals ( 3 ) can be made easier and optimized from the liquid. The excretions and algae can also accumulate on the substrate layer ( 28 ) and here from the feed animals ( 3 ) are eaten. In general, an extended dwell time of the culture water, e.g. through the ebb simulation or in some other way ( 5 ) in the animal feed filter ( 7th ) and / or plant filters contribute to the optimization of the filter function.

The flooding device ( 36 ) can change the relative water level in different ways. In the embodiment shown, for example, the hydroponic plant pots ( 35 ) connected to each other by a carrier and their height within the container ( 23 ) can be changed with a controllable actuator. In another embodiment, the water level ( 41 ) can be increased and decreased. In a third variant, adjustment on both sides is possible.

An increase and decrease in the water level ( 41 ) in the various stacked bins ( 22nd , 23 ) or in the tower or cascade arrangement is possible in the following way. Through the fluid inlet ( 33 ) culture water ( 5 ) into the container ( 22nd , 23 ) until the water level ( 41 ) the overflow point of the siphon ( 31 ) achieved. If this point is exceeded, ( 30th ) a suction siphon effect due to the negative pressure. This causes the culture water ( 6th ) the end the container ( 22nd , 23 ) is emptied faster than it can be refilled. As soon as the water level ( 41 ) has dropped to a critical point, the siphon ( 31 ) Air and the siphon effect collapse. Then the principle starts all over again.

The bottom substrate layers ( 28 ) or hydroponic layers have a gradient of 8%, for example. At its lowest point is the siphon ( 31 ) at the end of the in the container ( 22nd , 23 ) protruding drain pipe ( 30th ). This enables the largely complete emptying of the culture water ( 5 ) from the container ( 22nd , 23 ) and the short-term drainage of the soil substrate. This process is necessary for the oxygenation of the substrate and the optimal function of the animal feed filter ( 7th ) or plant filter ( 8th ) significant.

The bottom substrate layer ( 28 ) can also be laid eggs ( 3 " ) of the feed animals ( 3 ) take up. All or part of the eggs ( 3 " ) can be removed from the container (s) shortly after the eggs are laid and before the hatchlings ( 23 ) and stored in the memory ( 75 ) are brought to temporary storage. Part of the eggs ( 3 " ) can in a variant in the container or containers ( 23 ) remain for hatching young animals.

2 and 3 illustrate a hydraulic circuit diagram of the first variant of the aquaculture system ( 1 ) for the connection of the culture container ( 6th ), Feed filter ( 7th ), Filter ( 8th ) and algae reactor ( 9 ). The culture water ( 5 ) is used in the aquaculture facility ( 1 ) in a closed water cycle ( 13th ) guided. If necessary, a water supply ( 10 ) Fresh water is supplied. At a water drain ( 11th ) used culture water ( 5 ) out of the cycle ( 13th ) can be removed. Furthermore, in the water cycle ( 13th ) a water treatment ( 20th ) be arranged.

For the circulation of the culture water ( 5 ) in the water cycle ( 13th ) are one or more pump sumps ( 16 , 18th ) with one or more assigned pumps ( 17th , 19th ) intended. The pump sumps can be used as a collecting tank for the culture water ( 5 ) be trained. To a pump sump ( 16 , 18th ) several fluid connections ( 12th ) and several customers or components ( 6th , 7th , 8th , 9 ) of the aquaculture facility ( 1 ) must be connected. The fluid connections ( 12th ) between the various components of the aquaculture system ( 1 ) are formed by the said, preferably closed lines.

According to 2 and 3 is the culture container ( 6th ) on the outlet side via a fluid connection ( 12th ) with a first pump sump ( 16 ) connected on the input side. On the output side, the pump sump ( 16 ) multiple fluid connections ( 12th ) on. On the one hand, it is via a return line ( 24 ) with the fluid inlet ( 33 ) of the culture tank ( 6th ) tied together. In the return line ( 24 ) the mentioned water treatment ( 20th ) be arranged. Furthermore, the pump sump ( 16 ) via a fluid connection ( 12th ) with the animal feed filter ( 7th ) connected on the inlet side.

The feed animal filter is on the outlet side ( 7th ) with a second sump ( 18th ) tied together. From this sump ( 18th ) the filter ( 8th ), especially plant filters. The culture water ( 5 ) can be extracted from the filter ( 8th ) via a return line ( 26th ) into the second pump sump ( 18th ) flow back. This can be done, for example, by gravity. Furthermore, the culture water ( 5 ) from the second sump ( 18th ) via a return line ( 25th ) on the animal feed filter ( 7th ) over to the first sump ( 16 ) are funded.

The algae reactor ( 9 ) is also via a fluid connection ( 12th ) to the second pump sump ( 18th ) connected on the inlet side. In this fluid connection ( 12th ) the aforementioned inflow and outflow ( 10 , 11th ) are located. On the outlet side is the algae reactor ( 9 ) with the animal feed filter ( 7th ) tied together.

Part of the fluid connections ( 12th ) can be formed by active delivery lines in which pump pressure is present. Other fluid connections ( 12th ), especially the return lines ( 24 , 25th , 26th ) can be passive delivery lines in which the culture water ( 5 ) flows by gravity.

3 shows the hydraulic circuit diagram of 2 and additionally the spatial allocation of the components of the aquaculture facility ( 1 ). One or more discontinuous fluid connections ( 21 ), through which the water flow can be temporarily shut off. Such a discontinuous fluid connection ( 21 ) is e.g. on the inlet and outlet side fluid connections ( 12th ) of the algae reactor ( 9 ) arranged.

As 3 clearly shows, the culture water transport through the feed animal filter ( 7th ) and / or through the filter ( 8th ), especially plant filters, are carried out by gravity and in a cascade-like filter arrangement. The pump ( 17th ) promotes the culture water ( 5 ) from the first sump ( 16 ) via a fluid connection to the animal feed filter ( 7th ), especially to its upper fluid inlet ( 33 ). From this fluid connection ( 12th ) branches off the return line ( 24 ) to the culture tank ( 6th ) and its fluid inlet ( 33 ) away. From the culture container ( 6th ) the culture water can be drained via the fluid drain ( 29 ) by gravity to the lower-lying first pump sump ( 16 ) flow.

The second sump ( 18th ) is above the first pump sump ( 16 ) and below the animal feed filter ( 7th ), with its pump ( 19th ) the culture water ( 5 ) to the filter ( 8th ), especially plant filter, and preferably to its upper fluid inlet ( 33 ) promotes. Via the return line ( 26th ) the culture water flows ( 5 ) on the outlet side from the filter ( 8th ) by gravity back to the second pump sump ( 18th ).

The pump ( 19th ) can on the other hand via a corresponding valve arrangement and discontinuous fluid connection ( 21 ) Culture water ( 5 ) on the inlet side of the algae reactor ( 9 ) pump. From here the Algae suspension ( 40 ) by gravity directly to the animal feed filter ( 7th ) or in its fluid connection ( 12th ) from the first sump ( 16 ) flow.

The water flows within the aquaculture facility ( 1 ) can be of different sizes, whereby the distribution over the pump sump (s) ( 16 , 18th ) in connection with corresponding control means, in particular valves, takes place. Between the culture container ( 6th ) and the first sump ( 16 ) e.g. 1,000 l / h via the return line ( 24 ) pumped over. The container ( 22nd ) or feed animal filter ( 7th ) Due to the retention time, a reduced volume flow of e.g. 300 l / h is supplied and after passing through the second pump sump ( 18th ) directed. The plant filter ( 8th ) supplied volume flow can be reduced even more. It can be 100 l / h, for example. The remaining 200 l / h can be transferred via the return line ( 25th ) back to the first sump ( 16 ) are supplied.

At the in 4th shown embodiment of the aquaculture system ( 1 ) is an additional storage container ( 54 ) for the culture water ( 5 ) in the cycle ( 13th ) arranged for the culture water. In addition to the pump sumps ( 16 , 18th ) arranged. The storage container ( 54 ) can have a volume that corresponds to the in the circuit ( 13th ) exceeds the amount of water circulated every hour, in particular by a multiple. The additional storage container ( 54 ) can exist more than once.

The container ( 23 ) for growing plants ( 4th ) is independent with its own fluid connection ( 12th ) to the storage container ( 54 ) connected. This can create a sub-cycle ( 13a ) for filtering the culture water ( 5 ) and for separating said dissolved precipitates. The fluid connection ( 12th ) can have its own pump arrangement, in particular its own pump sump. For the sake of clarity, this is not shown in the drawing.

The fluid connection ( 12th ) or the sub-cycle ( 13a ) can with the possibly multiple arranged containers ( 23 ) be connected in a suitable manner. In 4th an embodiment is shown in which the containers ( 23 ) are arranged next to each other and possibly at the same height. They are parallel to the fluid connection ( 12th ) or the sub-cycle ( 13a ) connected. Alternatively, the aforementioned tower or cascade arrangement of containers ( 23 ) possible. Here are the containers ( 23 ) arranged one below the other in the cascade and, for example, connected in series for a water flow by gravity.

The single or multiple existing container ( 22nd ) for rearing feed animals ( 3 ) can also be done via a sub-cycle ( 13c ) with the additional storage container (s) ( 54 ) be connected.

In the embodiment of 4th is the single or multiple existing container ( 22nd ) for rearing feed animals ( 3 ) on the outlet side via a fluid connection ( 12th ), especially over the one pump sump ( 18th ), with a fluid inlet ( 33 ) of the additional storage container ( 54 ) tied together. This fluid inlet ( 33 ) is separate from the connection of the one or more containers ( 23 ) for growing plants ( 4th ) on the additional storage container ( 54 ) arranged. From the container or containers ( 22nd ) or from the animal feed filter ( 7th ) can thereby prevent the separation of particulate excretions from aquatic organisms ( 2 ) filtered culture water ( 5 ) autonomous and independent of the connection of the plant filter ( 8th ) into the storage container ( 54 ) are fed in.

The feed animal filter ( 7th ) or the one or more containers ( 22nd ) for rearing feed animals ( 3 ) to the other and first pump sump ( 16 ) connected.

A fluid drain ( 29 ) of the additional storage container ( 54 ) is via a fluid connection ( 12th ) with a fluid drain ( 29 ) of the culture tank ( 6th ) tied together. This creates another sub-cycle ( 13b ) for the culture water ( 5 ) educated. The in the storage container ( 54 ) culture water collected and at least partially freed from the particulate and dissolved excretions ( 5 ) can be put directly into the circuit ( 13th ) or the return line ( 24 ) are fed in. This can be done by a gradient or internal pressure or by a pump arrangement, possibly with a pump sump. Alternatively, the fluid drain ( 29 ) of the culture tank ( 6th ) with a downstream common pump sump ( 16 ) be connected.

In the arrangement shown, the animal feed filters ( 7th ) and the plant filter ( 8th ) separately from each other and independently to the additional storage container ( 54 ) connected. This also creates independent filter circuits ( 14a , 14b ) educated. The in the relevant sub-cycles ( 13a , 13b , 13c ) or filter circuits ( 14a , 14b ) circulated delivery rates or volumes of the culture water ( 5 ) can be of different sizes. Said filter processes or filter stages can run simultaneously or at different times. They can be carried out continuously or intermittently. The additional storage container ( 54 ) the entire filter process is optimized. The cycle ( 13th ) for the culture water ( 5 ) can be taken from the storage container ( 54 ) permanently filtered and purified culture water ( 5 ) are supplied.

On the outlet side are the feed animal filters ( 7th ) or the one or more containers ( 22nd ) for rearing feed animals ( 3 ) to the pump sump ( 18th ) and its pump arrangement ( 19th ) connected. From here at least part of the culture water supplied and filtered with regard to the particulate excretions ( 5 ) into the additional storage container ( 54 ) pumped.

The pump sumps ( 16 , 18th ) or their collecting containers are arranged adjacent. They can be fluidly connected to one another. In particular, part of the pre-filtered culture water ( 5 ) from the pump sump ( 18th ) into the pump sump ( 16 ) enter directly through the fluid connection. The pump sumps ( 16 , 18th ) can be accommodated in a common mixing tank with a partition to separate the collecting tanks.

From the common pump sump ( 16 ) the culture water ( 5 ) to the culture tank ( 6th ) and to the animal feed filter ( 7th ) pumped. The delivery rates can be the same or different. In one embodiment, two thirds of the total delivery rate to the culture container ( 6th ) and the remaining third to the animal feed filter ( 7th ) promoted.

The additional storage container ( 54 ) is a first modification. It can also be used in the first variant of the aquaculture system ( 1 ) according to 2 and 3 be arranged. It can be arranged there at a suitable location, e.g. between the pump sumps ( 16 , 18th ).

The aquaculture facility ( 1 ) according to a further additional aspect of the invention, an additional storage container ( 53 ) for a nutrient solution ( 5 ' ) exhibit. The nutrient solution ( 5 ' ) can be based on salt water or fresh water. The additional storage container ( 53 ) can be added to the aforementioned additional storage container ( 54 ) for the culture water ( 5 ) upstream and, if necessary, a fresh nutrient solution ( 5 ' ) controlled feeding. The nutrient solution ( 5 ' ) is formed from fresh water and preferably only from inorganic nutrients, in particular nutrient salts, electrolytes and inorganic fertilizers as well as minerals and trace elements.

The storage container ( 53 ) for the nutrient solution ( 5 ' ) can be connected to another storage container ( 52 ) for fresh water or, if necessary, directly with a connection ( 50 ) for the supply of fresh water, especially well water or tap water. The connection ( 50 ) a filter device ( 51 ), in which the fresh water is subjected to intensive filtering. This can be, for example, reverse osmosis or ultra-filtration. In the possibly existing storage container ( 52 ) the filtered fresh water, especially osmosis water, can be stored.

If a saline nutrient solution ( 5 ' ) or salty culture water ( 5 ) is required, the fresh water or osmosis water or the already formed nutrient solution ( 5 ' ) Salt can be added in a controlled manner in a suitable dosage. Suitable mixing devices and mixing containers (not shown) can be provided for this purpose.

The storage container ( 53 ) for the nutrient solution ( 5 ' ) can also be used with the first variant of the cultural facility ( 1 ) from 2 and 3 to be available. It can also be found there between the pump sumps ( 16 , 18th ) be arranged.

The additional storage container ( 53 ) for the possibly saline nutrient solution ( 5 ' ) can with the plant filter ( 8th ) or the one or more containers ( 23 ) for growing plants ( 4th ) via its own switchable water circuit ( 13 " ) be connected. This water cycle ( 13 " ) for the nutrient solution ( 5 ' ) can from the water cycle ( 13th ) for the culture water ( 5 ) be separated.

The storage containers ( 52 , 53 , 54 ) or tanks T1, T2, T3 and, if applicable, the water connection ( 50 ) as well as the filter device ( 5 ) can be part of a water supply ( 87 ) be.

This may mean fewer parts, in particular only the storage container or containers ( 53 , 54 ) exhibit.

According to one aspect of the invention, the aquaculture facility ( 1 ) an independent nutrient cycle ( 15 " ) exhibit. The plants ( 4th ) of the plant filter ( 8th ) can thus be independent of the filter circuit ( 14th ) are fed. The nutrient cycle ( 15 " ) can by means of the switchable water circuit ( 13 " ) are formed. In the nutrient cycle ( 15 " ) can have its own pump sump ( 70 ) or a separate pump arrangement must be available. Those in the nutrient cycle ( 15 " ) circulated delivery rates of the nutrient solution ( 5 ' ) can be significantly larger than the circulated delivery rates of the culture water ( 5 ) in the sub-cycle ( 13a ) or filter circuit ( 14a ) with connection of the plant filter ( 8th ) to the storage container ( 54 ) for the culture water ( 5 ) be. In the containers ( 23 ) for growing plants ( 4th ) the nutrient content can be reduced and reduced to one for the culture water ( 5 ) be reduced to a tolerable level.

According to a further aspect of the invention, the aquaculture facility ( 1 ) an independent feeding cycle ( 15 ' ) for the feed animals ( 3 ), especially the marine worms. The feed animals ( 3 ) are used with algae, especially an algae suspension ( 40 ), from the algae reactor ( 9 ) fed. The algae reactor ( 9 ) and the container or containers ( 22nd ) for rearing feed animals ( 3 ) are via their own switchable water circuit ( 13 ' ) for the algae suspension ( 40 ) connected with each other.

Through the pump sump ( 69 ) and the pump arrangement is the algae suspension ( 40 ) in the switchable water circuit ( 13 ' ) circulated. The water cycle ( 13 ' ) for the algae suspension ( 40 ) can from the water cycle ( 13th ) for the culture water ( 5 ) or from the filter circuit ( 14th ) are separated.

The diet of the feed animals ( 3 ) can be carried out during pauses in which the filtering process in the animal feed filter ( 7th ) has stopped or is relocated. The nutritional process can be controlled, e.g. by measuring the turbidity in the water cycle ( 13 ' ) recirculated algae suspension ( 40 ). As the food animals eat more and more ( 3 ) from the algae suspension ( 40 ) clarifies this. After the feeding process of the feed animals has ended ( 3 ) with algae, the filtering process of the animal feed filter ( 7th ) must be started again.

In the aquaculture facility ( 1 ) the aforementioned containers ( 6th , 22nd , 23 , 52 , 53 , 54 ) each be available in a single arrangement or a multiple arrangement.

This can e.g. be attached to the culture container ( 6th ) must be assigned or connected upstream. The water treatment ( 20th ) can for example have a UV filter and / or oxygen enrichment and / or degassing and / or a skimmer. In the 2 and 3 The indicated arrangement can also be used in the aquaculture facility ( 1 ) from 4th to be available. It is not shown there.

In the water cycle ( 13th ) for the culture water ( 5 ) and / or the nutrient solution ( 5 ' ) at least one measuring device ( 43 ) be arranged. This can be a single or multiple arrangement. A measuring device ( 43 ) is e.g. on the pump sumps ( 16 , 18th ) or the mixing container there. The measuring device ( 43 ) can detect a turbidity and / or a pH value and / or ingredients in the water. Such ingredients can be, for example, oxygen, carbon dioxide, common salt, nitrogen oxides, ammonia, phosphate, metals or the like. A measuring device ( 43 ) can also be attached to a culture tank ( 6th ) or on a storage container ( 53 , 54 ) for the culture water ( 5 ) or the nutrient solution ( 5 ' ) be arranged. The one or more measuring devices ( 43 ) are with the control ( 44 ) tied together. Based on the measurement results, the aquaculture facility ( 1 ) controlled and, if necessary, regulated.

The measuring device ( 43 ) can be used in both variants of the aquaculture system ( 1 ) to be available.

The algae reactor ( 9 ) can be designed in any suitable manner. This can be, for example, a training according to WO 2016/012489 A1 be. Alternatively, the algae reactor ( 9 ) also have a closed container.

4th until 5 show another embodiment. It is designed, for example, as a so-called open pond. The algae reactor ( 9 ) has one with water, especially with a nutrient solution ( 5 ' ), filled, ventilated and open-topped reactor vessel ( 27 ) on. The reactor vessel ( 27 ) has a ring-like shape in plan view and is covered with an algae suspension ( 40 ) filled. The algae suspension ( 40 ) preferably contains microalgae. The algae reactor ( 9 ) also has a circulation device ( 37 ) to circulate the algae suspension ( 40 ) in the ring-shaped reactor vessel ( 27 ) with the formation of a calm circulatory flow in the direction of flow ( 38 ) on. The circulation device ( 37 ) is designed, for example, as a paddle wheel with a controllable electric drive motor. The circulation device ( 37 ) can occur at a narrow point in the reactor vessel ( 27 ) are located. The reactor vessel ( 37 ) one or more control devices ( 39 ) for the circulating flow of the algae suspension ( 40 ) exhibit. The algae reactor ( 9 ) can be used individually or several times in the aquaculture facility ( 1 ) to be available.

7th until 9 show an embodiment of the culture container mentioned at the beginning ( 6th ). This can, for example, be trough-shaped and have an elongated, in particular cuboid, shape. The culture container ( 6th ) has a fluid inlet ( 33 ) and at the opposite other end a fluid drain ( 29 ) on. The fluid drain ( 29 ) can have an upper fluid vent ( 64 ) for surface water and a lower fluid vent ( 65 ) for soil water. Fats, oils and other rather unfavorable components in the culture water ( 5 ) collect on the water surface or at the water level ( 41 ) and can be accessed via the upper fluid vent ( 64 ) are withdrawn separately from the soil water. In the area of the bottom water, a calm flow from the inlet ( 33 ) the end ( 29 ) exist.

A tub-like overflow ( 63 ) for the surface water. The overflow ( 63 ) can be adjustable. For example, it can have a height-adjustable overflow wall. The upper fluid vent ( 64 ) ends at the overflow ( 63 ).

An upper fluid vent ( 64 ) must be present at the overflow ( 63 ) opens. The fluid outlet ( 64 ) alternatively be an upper fluid inlet. This can lead to the inlet ( 33 ) add to.

The fluid extractors (64, 65) can each be arranged several times. They can also be adjustable. The lower fluid drain ( 65 ) can be designed in any way and, if necessary, switched or controlled.

At the lower fluid drain ( 65 ) is e.g. a front panel ( 66 ) on the front wall of the culture tank ( 6th ) arranged at a distance from the bottom of the culture container ( 6th ) Has. Behind the wall-shaped panel ( 66 ) becomes a cavity ( 67 ) educated. This is located between the front wall of the container and the rear of the panel. The upright cavity ( 67 ) is in the upper area with the lower fluid vent ( 65 ) tied together. The cavity, for example, let into the front wall of the container ( 67 ) a narrowing tapering towards the top ( 68 ) exhibit. For example, he can use the in 8th have shown upright triangular shape. The fluid vent is located at the upper constriction area ( 65 ). The narrowing ( 68 ) can through the side walls of the groove-like and the cavity ( 67 ) forming recess are formed in the container end wall. This arrangement allows in the area of the lower fluid vent ( 65 ) a negative pressure can be generated. The soil water in the lower area of the container can thus be continuously and evenly removed from the culture container ( 6th ) subtracted from.

In the culture container ( 6th ) can according to 9 a measuring device ( 43 ) be arranged. With this, for example, the turbidity of the culture water ( 5 ) can be recorded. Depending on the turbidity, the circulation of the culture water ( 5 ) and the filter processes can be controlled or regulated. Furthermore, an outlet ( 61 ) for emptying the culture container ( 6th ) be arranged. At the bottom of the culture tank ( 6th ) is the substrate mentioned at the beginning ( 28 ) with the feed animals ( 3 ). In the culture water ( 5 ) the aforementioned inorganic nutrients are also included.

10 until 18th show a structural design and arrangement of containers ( 22nd ) for the rearing of feed animals ( 3 ). In a corresponding way, containers ( 23 ) for growing plants ( 4th ) be trained. The design and arrangement of the containers shown ( 22nd , 23 ) also has an independent inventive significance. It can also be used in other known aquaculture facilities ( 1 ), in particular according to the WO 2016/012489 A1 , can be used.

The containers ( 22nd , 23 ) can be arranged one above the other in a tower or cascade arrangement. In the embodiment shown, several individual containers ( 22nd , 23 ) arranged in a stack directly on top of one another with mutual contact and support. In a cascade arrangement, several containers ( 22nd , 23 ) be arranged one above the other and with a lateral offset, for example in the manner of a stepped terrace arrangement. Alternatively, several containers ( 22nd , 23 ) be arranged one above the other with mutual distance, e.g. in a tower-like manner on a shelf or rack.

In the embodiment shown, the individual containers ( 22nd , 23 ) a suitable cross-sectional shape, which can be, for example, circular, oval or prismatic. The circular design shown has structural and functional advantages in terms of stability, stackability and animal husbandry ( 3 ). The individual containers ( 22nd ) each have a circumferential upright side wall ( 56 ) within which a floor ( 59 ) is arranged in a raised position and preferably lying at a distance from the underside of the container. The floor ( 59 ) is supported by a support device ( 62 ) over the side wall ( 56 ) supported. The support device ( 62 ) can e.g. from below the ground ( 59 ) arranged cross members, which are attached at both ends to the side wall ( 56 ) are attached and, if necessary, can protrude through this to the outside.

The floor ( 59 ) has a gradient ( 60 ). At the deepest point of the floor ( 59 ) is on the container ( 22nd , 23 ) a closable outlet ( 61 ) arranged. This can be found in the side wall ( 56 ) and can be operated from the outside. On the floor ( 59 ) is the mentioned substrate layer ( 28 ), especially in the form of a layer of sand, with food animals contained in it ( 3 ) of the type mentioned. Due to the slope and the outlet ( 61 ) the substrate layer ( 28 ) and the feed animals ( 3 ) can be drained and removed.

The side wall ( 56 ) the upper container ( 22nd , 23 ) in the stack has a lower height than the side wall ( 56 ) of the lower container ( 22nd , 23 ). The side wall ( 56 ) the upper container ( 22nd , 23 ) has foot parts ( 57 ), which are spaced in the circumferential direction and with the formation of openings ( 58 ) in the side wall ( 56 ) are arranged distributed. The foot parts ( 57 ) are supported on a corresponding, ring-like upper side of the side wall ( 56 ) of the next container ( 22nd , 23 ) and are listed here. The openings ( 58 ) allow ventilation and lighting in the container stack.

In the containers ( 22nd , 23 ) there is a fluid drain ( 29 ) arranged. It has an upright drainpipe ( 30th ) on which the sloping floor ( 59 ) interspersed. At the top of the drain pipe ( 30th ) is e.g. a siphon ( 31 ) at a distance above the ground ( 59 ) arranged, which has the function described above. Below the bottom ( 59 ) shows the fluid drain ( 29 ) a transversely directed, e.g. tubular fluid transfer ( 34 ) at the lower end of the drain pipe ( 30th ) connected. The fluid transfer ( 34 ) forms the fluid inlet ( 33 ) for the next deeper container ( 22nd , 23 ) and ends at a distance above its bottom ( 59 ).

The fluid transfer ( 34 ) can have outlet openings ( 32 ) exhibit. In the case of the lower container ( 22nd , 23 ) the fluid transfer ( 34 ) through the side wall ( 56 ) led to the outside and connected to a fluid connection ( 12th ) must be connected. Depending on the distribution of the outlet openings ( 32 ) at the fluid transfer line ( 34 ) on the upper container or containers ( 22nd , 23 ) a sprinkling function or a surge transfer can take place. The fluid transfer ( 34 ) can instead of the straight pipe shape shown with a central connection to the drain pipe ( 30th ) have any other shape, for example in a star or ring arrangement. With the arrangement shown, the fluid transfer line ( 34 ) in the said cascade the culture water ( 5 ) or possibly a nutrient solution ( 5 ' ) from a container ( 22nd , 23 ) can be placed directly in the next lower container in the stack.
