Definitions
- the invention relates to a method and apparatus for separating the thick phase from the thin phase in a
- Fluid containing suspended matter such as
- Such a device is known from EP 0 052 722 B1 for separating manure or sewage sludge into a solid and a liquid phase. The revealed there
- Arrangement shows a large container, which is provided near the bottom with a flat filter, through which the water after filtration in a kind of clear water cellar
- Biogas plant is fed before or during the fermentation process to desulfurize during the biogas process or the biogas plant.
- the biogasification process is mainly an anaerobic process. If the fermentation residues are removed from the fermenter, they are aerated on the atmospheric oxygen.
- the invention is therefore based on the object, the
- Odor treatment agent is specified in claim 42.
- Core of the process according to the invention according to claim 1 is that the manure before being introduced into a settling tank mixed with a precipitant, or a precipitant of the manure is supplied, and subsequently in
- the manure is collected before being introduced into the settling tank in a collecting tank before the manure is then filled into the settling tank. This then leads to the homogeneous treatment in the following
- Flakes immediately generate buoyancy so that the flakes float much better in the settling tank. This results in a much better separation of liquid phase and flocks produced by precipitation.
- the settled thick phase is subtracted, i. is drained or sucked off and subjected to further dehydration by the thick phase of a further stage for dehydration is supplied. That Here, a two-stage drainage of the manure is made, with an additional precipitation is generated. As a result of the precipitation, in addition to the substances already present as suspended matter, the flocculations are also stripped of the flocculations produced during the precipitation.
- the thick phase is centrifuged, that is supplied to a centrifuge, and / or is guided over an obliquely exposed sieve, in which the further deposition of liquid from the thick phase is accomplished by the Coanda effect. This further drainage of the already withdrawn thick phase of manure leads to a further compression of the remaining thick phase.
- Centrifuge is operated in such a way that the
- Fluid itself is rotated in a fixed tube or container such that the deposit is deposited by the action of centrifugal forces on the liquid in the thin and thick phases.
- a second equally advantageous alternative is that the thick phase is passed over a continuously or discontinuously moved filter belt at the water passes through and is collected below, and above the suspended matter together with the precipitated
- Flocculation as further dewatered thick phase is scraped off with a ruler on the filter belt moved past it.
- the separation in the settling tank as Klarzone separable and / or after centrifugation and / or filtration
- Air oxygen vented is fed to a denitrification.
- the thin phase or clearing zone which can be separated in the settling tank as clear zone and / or withdrawn after centrifuging and / or filtering is cleaned or aftertreated in a reverse osmosis process.
- the withdrawn thin phase or Klarzone called, an aquatic crop plant according to
- WO 2010043323 is supplied, or can be.
- the quasi-regressive contribution from the thin phase with only one day or less time lag already produces aquatic biomass from it. This is due to the fact that in the said cultural facilities for aquatic plants, in particular duckweed, the biomass yield thereby achieved is already available after one day. This is a possibility for the reduction of ammonium or nitrates in the thin phase or the
- Drying or dry fermentation can also be composted or pelleted. It is further designed that in agricultural manure or digestate from biogas plants or other Vergährungsanlagen after precipitation of manure or
- Clear phase existing precipitated manure or digestate can be filled into a filter, that the filter is a at least two-layer filter, which consists of a solid
- Filter is designed as a filter bag, which is suspended, and lingers after filling for an expiry time in a suspended position. Such a filter system is extremely easy for the application mentioned.
- Carousel be hung and moved to drip.
- Such a system is highly effective because it allows a relatively large filter volume to be created which is easily expandable by only adding more filter bags.
- Odor treatment is that the Odor treatment substance AFTER final degassing of a biogas fermentation substrate, the relevant digestate or slurry is fed / mixed BEFORE application to agricultural land or landfills.
- Hydrogen sulfide is not just an extreme
- the advantage is achieved that when applying the biosubstrate on arable land, the resulting odors are significantly reduced or completely eliminated.
- the biosubstrate treated in this way is agricultural liquid manure, at least from liquid manure from livestock farming, and / or from fermentation residues from biogas production, and / or from vinasse from bioethanol production, and / or process-technological waste products from the foodstuffs - or sugar production, and / or slaughterhouse waste.
- biosubstrates are usually extremely odorous and without odor treatment is a huge burden on the local residents.
- This odor treatment substance according to the invention this can be eliminated, wherein the odor control material is readily biodegradable.
- Iron chlorides (ferrous chloride, ferric chloride, which is mixed with a wetting agent.
- it is configured such that one or more surfactants or surfactant / water mixtures are admixed with the iron chloride or the iron chlorides as wetting agents. This prevents that from happening
- a special feature of the invention is that precipitation occurs in the mixture of iron chlorides with surfactants. At the same time, however, iron chloride reacts with the hydrogen sulfide compounds which are often responsible for the odor load. Thus, simultaneous addition of surfactants to ferric chloride causes two reactions.
- Odor treatment substance contains at least one nitrate. Nitrates themselves contain the anion N03. This is needed among other things by plants for the amino acid formation, and is regarded as elementary food of green plants, also of higher aquatic plants.
- the cation calcium and / or potassium is needed for plant growth.
- both an odor damping and fertilization is effected at the same time. Since the same effect applies to the dissolved surfactants, the odor treatment is effective for odor reduction and at the same time not only biodegradable, but even conducive to those with the
- Residues fertilized crops Residues fertilized crops.
- the odor treatment substance is mixed with water. This makes the odor treatment substance easier to dose.
- monocyclic monoterpene and citral These substances are also biodegradable and are effective in reducing odor.
- the mixing ratio in the aggregate is the proportion of monocyclic monoterpene between 90% to 97% and the proportion of citral is 3% to 10%.
- Sludge is subsequently admixed with a mineral flour.
- the starting material of the additive is formed from lemon oil, and that as a source of lemon oil
- lime-containing plants or plant pomace are used.
- biosubstrate treated in this way is added to or added to the culture water of an aquatic cultural facility, for example according to DE 2008 050 974.
- Cultural institutions of this kind work with stacked tub cultures, in which aquatic plants can be cultivated for a wide variety of uses. The practical effect is that this expediently, for example, with
- the culture system is in
- Odor reducing agent is absorbed by the aquatic plants in all resulting in the solution in water products and metabolized, or can be.
- the essence of the invention is that the slurry before
- Injection point is fed to an inlet pipe of the manure to the settling tank, and subsequently in
- the suspended matter and / or the suspended matter formed by precipitation can be deposited as a thick phase, and subsequently the settled thick phase can be removed separately from the thin phase forming as a clear zone. This is easy to disassemble.
- the injection site for the precipitant may be integrated as a T-piece with valve directly on the line to the settling tank.
- the thick phase settles down under the influence of gravity, and by suction in the settling tank integrated mechanical conveying means or generating a directed flow through arranged at the bottom Abziehö réelleen or -stutzen or vacuum can be sucked. So is simple
- the settling tank has a bottom, which extends inclined to the horizontal at least along one direction, and at the lowest point of the Abziehö réelle or -stutzen is arranged.
- the bottom of the settling tank is inclined in at least two directions, such that forms a kind of gutter in the ground, which in turn slopes to the horizontal and at the lowest point in the draw-off or -stutzen.
- Fluid containing suspended matter such as
- a filter material for the filter for filtering the thin or clear phase, or the entire precipitated manure or digestate a consisting of at least two layers of filter material, wherein the upper Layer of a filter or a
- Microfilter fabric consists, and the lower layer consists of a flow material.
- the upper filter layer consists essentially of a Mikofilter für eg. Plastic, with holes in the range of about 50 microns to 1 millimeter, the holes are placed in a supporting fabric made of plastic. This upper filter layer is then facing the medium to be filtered.
- a second layer On the underside, i.e. facing away from the medium to be filtered, is a second layer in the manner of a
- the filter is designed as an existing from said filter fabric bag, which is provided at the lower end with a ring which serves as a dripping aid.
- a Filterkarusell is provided, on which a plurality of bag-shaped filter are suspended, which together in a down
