Description

, Title of the treatment method, and. Apparatus for the recovery of manure which can be stacked _; , '

Field of application of the invention

The invention relates to a method and a device for obtaining stackable fertilizer from plants of cattle, pork and poultry production, which are einstreulos managed or use such small amounts of bedding, since the litter obtained excrement / litter mixture is not stackable,. .

Characteristic of the known technical solutions

The previously known methods for the treatment of agricultural and municipal waste products to stackable substrates based on a mixing of the previously dehydrated product, with extinguishing or quicklime alone or in combination with water-absorptive -organic substances in comminuted form. The stackability is achieved by increasing the dry matter content. It is preferable to use quicklime in order to achieve a greater increase in the dry matter content through the chemical water binding during the hydroxide formation and the water evaporation as a result of the temperature increase that occurs. The particular disadvantage is that large amounts of lime, and organic additives are required by the 3 _rn öhung the Trοckensüb-

to achieve stackability.

In order to achieve the required for the stackability dry matter content without prior dehydration alone by addition of calcareous substances, so large amounts would be required that .Einsatz the product obtained is limited as organic fertilizer · In order to limit the amount of additives is therefore at a A series of processes leading to an energy-consuming and labor-intensive, cost-increasing mechanical dewatering upstream or downstream ·

Which method further have the disadvantage that the organic substances are added in comminuted form as possible 'to increase the water absorbency · having an increased Aufwand.an technical equipment, and · energy; As a consequence, it is furthermore disadvantageous that the greatly varying oil-dry substance content of the medium to be prepared necessitates the prior determination of the desaturation content in order to be able to measure the addition amount. Otherwise, additives must be added until the required dry-matter content has been reached in the case of short-term fluctuations in the dry matter content, that the required quantities of additive are not previously known ·

In the previously known processes mit.Kalkzusatz for reprocessing substrate, the recovery of the liberated ammonia is not provided and the mechanization agents used have no device for detecting liberated ammonia. The nitrogen, which can be used as a plant nutrient, is lost and the ammonia smell causes considerable environmental pollution. ^:

Object of the invention

The aim of the invention described below is to modify the colloid structure and the flow behavior from low dry solids content of hinder, pig and poultry manure by means of small amounts of the dry substance content which are insignificantly increasing, of constant proportions of mineral and organic nature, such that a stackable material Fertilizer 'is produced, which is stored at the edge of the field and applied to the stable manure spreader, whose application rate is easy to measure in crop production because of its largely uniform composition and which is administered on the basis of nitrogen content to the agricultural crops · Far far, the method allows for investigation of lime needs of recycling area by dia bond of lime to dia. Manure a significant improvement in the working conditions hay. Lime application · The ammonia released during processing into a stackable fertilizer is largely absorbed and can be used as a nitrogen fertilizer. Due to the lime content and the associated increase in the pH, the losses of organic matter are reduced by reduced microbiological conversions · Depending on the Aufberaitungsschritten contains the stackable fertilizer depending on the species and dry matter content of the slurry 40, 80 % of that in the excrement nitrogen, 60 ··· 100 % of the phosphorus and 30 · ..100 % of the potassium ·

Pig manure with 6 .. 15 ^ and Geflugelgülla <22%, the mixture, for discharging emerging liquid, after mixing with the aggregates in a separation vessel, preferential prices' dry bed, given. The stackability is achieved at a layer height of 2 m in the dry bed after 3 × 4 weeks.

The amount of additives is the same for both treatment variants and amounts to 3 ···· 5 % burn or slaked lime and-1 % straw, based on the mass of the slurry to be treated.

The burn or slaked lime is preferably mixed first.

The ammonia liberated in the mixing process is bound in an absorber and used as nitrogen fertilizer. Slurry with a dry matter content of <6%, preferably cattle and pig manure, is subjected to accelerated dehydration of a colloid-destroying physical treatment, preferably an ultrasonic treatment. For this purpose, the manure · in a line with a rectangular cross-section in a layer thickness of a maximum of 5 cm through an ultrasonic field, preferably 20 kHZ, passed, then dewatered in ainam separation vessel and then mixed with the Hälfta above mentioned manga of aggregates. The process with its dependent on the dry matter content of the manure used variants runs basically in, following Varfahrensschritten from: 'Die.Gülle is from dam container on the stable or from another reservoir by means known means, eg. Pumps, depending on the dry matter content with or without switched ultrasound treatment.

The ammonia emerging from the mixture during the mixing process and subsequent transport is removed by means of an exhaust ventilator S sucked out of the mixing and conveying enveloping enclosure and passed into an absorber ', where it is absorbed by substance, which have a large capacity for absorbing ammonia, and brought into a transportable form. These ammonia-enriched substances are used as nitrogen fertilizer inside or outside the manure processing plant of the animal production plant. The special device embedded in the method consists of a solid frame or structure in which an excrement or liquid receiving container, a lime storage container and a straw storage container are permanently installed.
