METHOD FOR PRODUCING A FERTILIZER NUTRIENT OR MICRONUTRIENT, AND A FERTILIZER NUTRIENT OR MICRONUTRIENT, AND CULTURE OR PLANTING SOIL ADMIXED THEREWITH
The invention relates to a method for producing a fertilizer nutrient or micronutrient, which contains at least ammonium nitrogen, according to the preamble of patent claim 1, and to a fertilizer nutrient or micronutrient per se, as well as to a culture or planting soil admixed with the fertilizer nutrient or micronutrient. In order to ensure that the fixing of the phosphor is prevented and that both phosphor and iron are present in the current vegetal form, and this within a common production process. In a first step of the method according to the invention, iron hydroxide is mixed with a mineral powder material; in a second step, ammonia-rich and phosphate-containing nutrient water, which has been separated from liquid manure by separation and/or precipitation, is added and mixed therewith; and in a last step, acid or acidified water is added and mixed therewith.
The invention relates to a method and a device for treating liquid manure and fermentation remains, according to the preambles of patent claims 1 and 12. To achieve the effect here that the so-called precipitation and separation of the liquid manure or the fermentation remains into a floc phase or thick phase and into a clear phase or thin phase takes place much more quickly and effectively, it is proposed according to the invention that the sedimentation tank is preceded by an upright precipitation tank, in which the liquid manure is introduced at the bottom and with turbulence, and a precipitating agent is continuously injected at the same time, and likewise at the bottom, into said turbulence of the liquid manure introduced, with the effect that the mixture of liquid manure or fermentation remains together with the injected precipitating agent rises upwards and expands in the precipitation tank, and so is discharged from the top of the precipitation tank and introduced into the sedimentation tank.
The invention relates to a method for treatment of agricultural liquid manure, by treating the liquid manure with precipitant in a settling and/or separating method and separating it into thick phase on the one hand and thin phase or clear phase on the other hand, and to a corresponding installation, according to the preamble of claims 1 and 15. In order to achieve optimization here of the precipitation even in the case of heavy liquid manures such that minimum amounts of precipitant are achieved with simultaneously optimal precipitation, it is proposed in accordance with the invention that, in addition, water be enriched at least with portions of hypochlorous acid and be used as separation medium, in such a way that the suspended substances which precipitate out in the reaction of the precipitant and the hypochlorous acid with the liquid manure float on the water separation medium and/or sink in the water separation medium, and a thick phase thus separable from a clear phase can be removed zone by zone.
The invention relates to a method and to a device for producing biomass consisting at least partially of aquatic plants for the production of feeds for animal or livestock nutrition, the plants being produced in a closed photobioreactor provided with stacked culture surfaces, according to the preamble of claims 1 and 12. In order to ensure that a reproducible direct intervention is made in the current plant production with regard to the desired resulting feed mixture, according to the invention the aquatic culture surfaces of the photobioreactor are divided into zones within the photobioreactor, in which zones different plant strains and/or plant genera having different constituent compositions can be grown and harvested cyclically, and the zones are divided up with respect to the attainable harvests in approximately the same ratio as the constituent composition of the plants cultivated therein with respect to the targeted constituent composition of the feed to be produced from a mixture of said harvested plants.
The invention relates to a method for treating agricultural liquid manure, in that the liquid manure is treated with precipitant in a settling and/or separation method and is separated into a thick phase and a thin phase or clear phase, according to the preamble of claim 1. In order thereby to increase markedly the separation of thick phase and thin phase or clear phase in pre-separated and non pre-separated liquid manure and permit in the result a year-round discharge of the thin phase of the liquid manure and utilization of the thick phase, according to the invention it is proposed that in addition water is used as separation medium, in such a manner that the suspended matter precipitating out in the reaction of the precipitant with the liquid manure floats on the separation medium water and/or falls in the separation medium water, and a thick phase thus separated from a clear phase can be separated off in a zone-type manner.

The invention relates to a method and an apparatus for separating the solid phase from the liquid phase in a liquid containing suspended matter, such as liquid manure, according to the preamble of claims 1 and 13. In order to be able to separate the solid phase from the liquid phase in such a way as to make the process more dynamic, prevent the outlet from being blocked as a result of clogged filters, and significantly reduce the energy required for separating the solid phase from the liquid phase, the liquid manure is mixed with a precipitation agent or a precipitation agent is fed to the liquid manure before the liquid manure is introduced into a settling tank, whereupon in the settling tank, the matter already suspended prior to the precipitation process and/or the matter suspended in the precipitation process is settled or separated as a solid phase, and then the settled or separated solid phase is separately withdrawn from the liquid phase forming as a clarified zone.
The invention relates to a method for operating a biogas system in which liquid manure from agriculture and/or fermentation pulp, which has already been partially degassed in a preceding fermentation process, and/or sewage sludge and/or waste from food production is/are fermented or further fermented as a fermentation substrate in another fermentation process, as well as to an apparatus, according to the preamble of claims 1 and 8. According to the invention, in a first step the solid phase of the liquid manure or the fermentation pulp previously partially degassed or the sewage sludge or the food waste is separated from the liquid phase thereof, the solid phase is then introduced into the digester of the biogas system, the liquid phase is fed to a cultivation device containing fast-growing aquatic plants, and at least some of the aquatic plant biomass, which can be regularly removed from the cultivation device, is fed to the digester of the biogas system filled with the solid phase.
The invention relates to a method and a facility for treatment of wastewater or process water, or treatment of process water from hydrothermal carbonization. In order in this case that the effluent water can be treated so effectively that the economic efficiency of the respective process from which the wastewaters arrive is considerably increased or are less polluted as a result of the purification, it is proposed according to the invention that the wastewater or process water or the effluent water of the hydrothermal carbonization (HTC) process is fed to at least one aquatic plant culture facility, in which the aquatic plant cultures are cultivated in culture troughs arranged stacked one above the other with intermediate spaces, and arranged in a closed photobioreactor, in such a manner that in or on the bottom of the aquatic culture system facility, a supply tank volume that is laid out so as to be flat is fed as buffer volume with wastewater or process water or HTC process water and diluted with mixed water, and that thereafter the process water/wastewater mixed water blend is supplied as culture water to the stacked aquatic plant cultures for vaporization.
