摘要:
Localized fertilization with excellent results is obtained through the use of a microgranular fertilizer composition where the composition granules have size within the range of 0.1 to 1.5 mm.
摘要:
The present invention relates to a method for the preparation of a biological fertilizer comprising subjecting whey to a first fermentation step and the addition of a carrier material to the fermented whey and a biological fertilizer obtainable by the method. The biological fertilizer can be used as a replacement of the present artificial fertilizers thereby reducing many of the environmental problems associated with these artificial fertilizers. In addition, the biological fertilizer according to the present invention can be used in the field of biological agriculture for which, until the present biological fertilizer, no fertilizers were available.
摘要:
In order to speed up the biooxidation processes and to reduce the number of turnings of the heaps in a biomass maturing and stabilizing process, suitable natural enzymatic mixtures have been resorted to which are prepared from vegetal components selected at the time of maximum vegetative development, i.e. during harvesting according to the use, and throwing away the withered or rotten portions, to which non-pasteurized milk is added. The preparation obtained in this way is poured onto the heap to be treated as homogeneously as possible.
摘要:
The invention comprises a multi-stage process and apparatus that converts various waste and lowvalue feedstocks, such as offal, animal manures, municipal sewage sludge, tires, and plastics, to produce useful materials, including gas, oil, specialty chemicals, and carbon solids, in reliable purities and compositions, at acceptable cost and with high energy efficiency, without producing malodorous emissions. The invention further provides for an apparatus for converting an organic liquor into a mixture of hydrocarbons and carbon solids, comprising: a heater for producing a mixture of liquid and vaporized oil from the organic liquor; a reactor for converting the mixture into carbon solids and a hydrocarbon/gas mixture; a first cooler for accepting the carbon solids; and a second cooler for accepting the hydrocarbon/gas mixture. The invention still further relates to a separator that separates out particulates of a dimension of about 1 micron, such as cellular debris from bacteria, from a surrounding fluid.
摘要:
There is provided a carcass disposer sterilizing a carcass by supplying high-pressure steam into a steam drum seated on one side of an upper portion of a base frame. The carcass disposer includes a cover installed upright to horizontally move along transfer rails installed on the other side of the base frame, and selectively opening and closing the steam drum; and a carcass loading table integrally connected to an inner surface of the cover, and being automatically taken in or out along transfer rails inside the steam drum as the cover is selectively opened and closed.

The invention features a product for improving soils by calcic deposits, consisting of oyster shells having been treated by crushing and optionally by dessication, excluding all treatment likely to modify the oyster shell chemical composition.
摘要:
Ein Verfahren zur Verwertung keratinhaltiger Abfälle besteht darin, daß den Abfällen Obsttrester bzw. frischer Obsttresterkompost zugemischt wird. Das Gemisch wird mit Wasser oder einem Granulierhilfsmittel versetzt und anschließend aerob kompostiert.
摘要:
Bei einem Verfahren zur Herstellung pasteurisierten tierischen und pflanzlichen Nährstoffen aus Siedlungs-, Industrie- und Landwirtschaftsabfall besteht ein erster Verfahrensschritt in der Versetzung von auf 22% TS dekantierten Klärschlammes mit den Umbau intensivierenden Zusätzen, wie Kohlenstoffspender, Kohlehydratspender bzw. Katalysator. Dabei wird das Gemisch umgerührt bis eine Prozesstemperatur von 20 - 30°C erreicht ist. In einem zweiten Verfahrensschritt werden organische Abfälle entsprechend höchstens 200% des Klärschlammgewichtes unter ständigem Umrühren des Abfallgemisches bis zum Erreichen einer Prozesstemperatur von 45 - 55°C zugeführt. Die Einstellung des Feuchtigkeitsgehaltes erfolgt mittels befeuchtender bzw. trocknender Zusätze, wie Gülle, Kadaversuppe, Flotationsabfall bzw. Papier, Holzstaubpellets, auf 30 - 40% TS. Schliesslich wird in einem dritten Verfahrensschritt das Abfallgemisch mit 2l Leuchtpetroleum je 1000kg Abfallgewicht bzw. einem Eiweiss- und einem Kohlenstoffspender geimpft. Das Impfgewicht beträgt ca 10% desjenigen des Abfallgewichtes und das MIschverhältnis 1 : 2. Dabei erfolgt intermittierendes Umrühren des Abfallgemisches mit einer Rührzeit von 10 - 20 Minuten und einer Stillstandszeit von 20 - 30 Minuten bis die Prozesstemperatur 68 - 80°C beträgt.
摘要:
Soybean meal and urea compositions have been found to exhibit enhanced and commercially useful nematistatic and nematicidal activity in soils. Chitin-protein complex containing materials, e.g., crab shells, shrimp shell, fungal mycelia, etc., and/or ammonium phosphate have also been found to exhibit enhanced and commercially useful nematistatic and nematicidal activity in soils when admixed with said soybean meal-urea compositions.
摘要:
Process for the purifying treatment of waste-waters from the dairy industry through the coagulation of the fat and protein content by treatment with chemicals and through the removal, in given case through the re-processing of economic utilization purpose of the forming waste sludge as well as an equipment for the effectuation of the process. The essence of the process consists in that the waste-water is destabilized for a definitive time in presence of a suitable bacterial flora between the formation and the chemical treatment and the destabilization is accelerated expediently by measures augmenting the contacting surface, in given case increasing the intensity of the contacting. The forming waste sludge or its solid content can be utilized by being burnt in furnace, being added to fodder or my ameliorating fertilization. The pre-purified waste-water can be advantageously after-purified by additionally applying an aero-biological (active-sludge) procedural phase.
