摘要:
The invention is directed to processes for treating biosolids that result in high-value, nitrogen-containing, slow-release, organically-augmented inorganic fertilizer that are competitive with less valuable or more costly conventional commercially manufactured fertilizers. The process involves conditioning traditional waste-water biosolids and processing the conditioned biosolids continuously in a high throughput manufacturing facility. The exothermic design and closed loop control of the primary reaction vessel decreases significantly the amount of power necessary to run a manufacturing facility. The process utilizes green technologies to facilitate decreased waste and enhanced air quality standards over traditional processing plants. The fertilizer produced from recovered biosolid waste is safe and meets or exceeds the United States Environment Protection Agency (USEPA) Class A and Exceptional Quality standards and is not subject to restrictions or regulations.
摘要:
A system for composting-free disposal of organic waste and method thereof included a heating apparatus, a pretreatment apparatus, and a decomposition apparatus. The heating apparatus heats the pretreatment apparatus and the decomposition apparatus. The organic waste is separated into a slurry and a surface oil-water mixed liquid by the pretreatment apparatus. Microbial enzymes and raw material are added into the slurry to become a mixture. The mixture is then decomposed and sterilized by the decomposition apparatus to become a composting-free organic fertilizer product. All these procedures can be carried out within 3 to 24 hours. The system and the method thereof provides an efficiently fast, space-saving way to deal with organic waste and achieve environmental protection and sanitation.
摘要:

The invention relates to a mixer device for materials, i.e. materials made up of various divided solid waste, in a vertical silo (1). Said device is characterized in that it comprises the following: a central working area extending along the entire height of the silo (1); a peripheral zone; means (6) which are distributed vertically at different successive levels (n1, n2, n3 ... n21) of the working area, along the entire height of the silo (1) and which can lift materials from each of the levels of the working area and release said materials; means (la, 19) for bringing matter from the upper part of the peripheral area to the lower center part of the silo (1).
摘要:
A composting system and method incorporating a vertical insulated composting tower with one or more compartments. The base of each compartment being fitted with a plenum and grate through which air is self induced and output is regularly removed. The method of composting biodegradable waste material utilises a plug flow principle including inducing low air flow rates through a compost pile using column energy. The method utilises high temperature pyro/thermopylic micro-organism activity in the compost pile and retaining pile energy above stoichometric levels by controlling the induced air flow. Evolved gas extraction is utilised in the compost pile and constant biofilm is maintained by combined cycle anaerobic/aerobic operation.
摘要:
An organic waste processing method which is capable of large-amount processing and 24-hour continuous processing and also capable of minimizing installation and processing costs; and a device therefor. The device comprises a plurality of linearly arranged approximately inverted frusto-conical processing tanks (3, 3A, 3B, 3C), motors (17) installed below the respective processing tanks, rotary shafts (19) supportably extending vertically through the respective processing tanks and driven for rotation by the motors (17), and agitating vanes (21) supported on each rotary shaft (19) for mixing aerobic microorganisms (1) and an organic waste (2), wherein a more-than-storable amount of organic waste (2) is charged into the upstream processing tank (3) and a portion of the organic waste (2) is subjected to the centrifugal force from the agitating vanes (21) to flow out through an outflow port (14) in the upper region of the peripheral wall of the processing tank (3) into an inlet port (9) in the upper region of the processing tank (3A) adjacently disposed downstream. This operation is repeated according to the number of processing tanks and a large amount of organic waste (2) is continuously aerobically fermented for conversion into compost.

摘要:
Ein Fermenter (1) einer kontinuierlich oder quasi kontinuierlich arbeitenden Fermentieranlage weist eine Annahmeeinheit (30) auf, von der das Frischgut entnommen und bei Bedarf zerkleinert in ein Zwischenlager (20) abgegeben werden kann. Das erfindungsgemässe Zwischenlager umfasst einen Laderaum (21), welcher als Muldenkonstruktion (22) gestaltet ist. Der Boden des Laderaumes (21) ist als Förderboden (23) gestaltet, der durch einen Antrieb (25) bewegbar ist. In der Austragsrichtung am Ende ist eine Dosier- und Austragseinheit (24) angeordnet. Mittels der Dosier- und Austragseinheit (24) und dem Förderboden (23) kann das zerkleinerte Frischgut aus dem Laderaum (21) kontinuierlich oder quasi kontinuierlich dosiert auf ein etwa horizontal verlaufendes Förderband (27) abgegeben werden. Mittels einem zweiten Förderband (28) lässt sich das Material weiter in eine Speiseeinheit (3) fördern, von wo es über die vorzugsweise beheizte Speiseleitung (2) in den Fermenter (1) eingetragen werden kann.
摘要:
Apparatus suitable for use in the treatment of waste and/or organic materials which includes a main body having a treatment chamber therein having a base which when the apparatus is in a harvestig mode is arranged with a space therebelow. The base includes a plurality of generally parallel spaced apart support elements (32), the support elements being spaced apart at a distance sufficient to support the material within the chamber during the treatment process and enable extraction of the treated material through the spaces between the support elements during a harvesting process. There is also disclosed a harvesting device comprising a plurality of extraction elements (108) which are adapted to project through the spaces between the support elements to dislodge and extract the treated material through the base. The apparatus and harvesting device is particularly useful for removing worm castings in vermiculture.
