Problems solved by technology

[0002] Organic waste refers to domestic garbage, dead leaves, human and animal manure, and waste after processing agricultural and sideline animal products. Most of these wastes are produced by retting. This kind of fertilizer has low fertilizer efficiency, long production cycle, low active ingredients, and odor. Not only pollute the environment, but also cause waste of resources

Embodiment 1

[0019] to combine figure 1 The reactor shown is a box or pool (1) type, with a gap (2) left on the inner wall, and a groove (not shown in the figure), and an overhead support (3) at the bottom, generally 30- 40 cm, the bottom has a drainage vent (4) that communicates with the ventilation box (5) in the reactor, and there are evenly distributed small holes on the wall of the ventilation pipe, the vent is connected with the fan (6), and the inner wall and the bracket and the ventilation pipe The top is evenly covered with bamboo strip mats with air holes in the inside. In the above reactor, first add waste pomace, nut shells and melon seeds, and the ratio is 100kg of mixture of 1:5:0.5. Put 40kg of water into the reactor and pile it with raw materials. The material layer is covered with plastic film. Temperature, when the temperature in the stacking reaction process shows a downward trend, drop to 40°C to take out the material, crush it, and then put the crushed material into t...

Embodiment 2

[0021] With the reactor of embodiment 1, get waste pomace, nut shell and melon seed, its proportioning is 5: 3: 2 mixed material 100kg, then get urea 0.3kg and be dissolved in 30kg water earlier and then add in the reactor and raw material heap The material layer is covered with plastic film, and the temperature of the material is 55°C. The exudate from the lower part of the suction reactor is circulated and sprayed back to the material, and the temperature is adjusted by strong ventilation from the ventilation pipe. When the temperature of the material reaction process is declining , down to 50°C, take out the material, crush it, then put the crushed material into the reactor for secondary stacking, add 15kg of water, when the stacking temperature is 60°C, stir and mix with a road mixer and cool down until Below 50°C, take out the material, dry and sieve to get -5mm catalyst, add 10kg for open-air composting to produce fertilizer, and add -1mm for human and livestock manure to...

Embodiment 3

[0023] With the reactor of embodiment 1, get waste pomace, nut shell and melon seed, its proportioning is that 100kg of the mixture of 10:0.5:5 is packed in the reactor, then 0.1kg urea is dissolved in 20 parts of water and adds reaction Stacking in the reactor, the material layer is covered with plastic film, the stacking temperature is 60°C, the seepage at the bottom of the reactor is sucked and circulated back to spray the stacking, and the temperature is adjusted by forced ventilation from the ventilation pipe in the reactor. The temperature of the material reaction process shows a downward trend. When the temperature drops to 40°C, the material is taken out and crushed. When the temperature is lowered until the temperature drops below 50° C., the materials are taken out, dried and sieved to obtain a catalyst with a particle size of -5 mm. For open-air composting to produce fertilizer, add 10kg, and -1mm for human and animal manure to produce fertilizer, add 9kg.

Abstract

The present invention relates to an active catalyst for decomposition of organic wastes. Its production method includes the following steps: using waste fruit skin, nutshell and melon seed nitrogen fertilizer as raw material, stacking, making forced aeration to make temp. regulation, regulating water content, rolling and pulverizing, secondary stacking, drying and sieving to obtain the 5 mm or 1 mm catalyst. Said catalyst can be used for producing fertilizer by using organic wastes, it can raise activity of fertilizer, it effective component is high, and has the advantages of odourless, low cost, convenient for transportation and does not pollute environment.

Description

(1) Technical field [0001] The invention relates to an active catalyst for organic waste decomposition, in particular to a catalyst capable of producing high-activity and high-quality fertilizers from organic waste, which belongs to biological engineering. (2) Background technology [0002] Organic waste refers to domestic garbage, dead leaves, human and animal manure, and waste after processing agricultural and sideline animal products. Most of these wastes are produced by retting. This kind of fertilizer has low fertilizer efficiency, long production cycle, low active ingredients, and odor. That is, it pollutes the environment and causes a waste of resources. (3) Contents of the invention [0003] The purpose of the present invention is just to overcome the shortcoming and deficiency of above-mentioned prior art, and provide a kind of active catalyst that can make organic waste decompose rapidly and deodorize rapidly, thereby can produce high-efficiency fertilizer, also ...
