Problems solved by technology

Its processing process has the following deficiencies: the microorganisms such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria used in this method are all room temperature bacteria, and cannot undergo high-temperature fermentation stage
Due to the use of beneficial microorganisms to inoculate the secondary fermentation (lower temperature) garbage dry powder, the process is complicated, the production cycle is lengthened, and the operating cost is increased; and the inoculant used is a single strain, which has a single function and is difficult to adapt to different conditions. Geography, different types of soil physical characteristics, different nutritional characteristics of different crops and different needs of the same crop at different growth stages and nutritional stages

Embodiment 1

[0015] The present embodiment is the method for producing multi-element organic fertilizer with municipal solid waste: first domestic waste is artificially sorted, air-flow sorted, magnetically separated and sieved, mixes 14.65% water content 80% in the rubbish of 85.3% by weight ratio -90% feces, cakes, then add 0.028% biocatalyst DBG, then add 0.022% deodorant EOC, spray water to adjust the water content to 35-45%, mix and stir evenly, pile up to 21 meters long, Strips with a width of 2.5 meters and a height of 2 meters are covered with a layer of fermented compost dry powder of about 3cm on the surface, and the air duct is opened to force ventilation into the pile, and the central temperature of the piled material is controlled at 75-85°C. The material mixer is turned over and stirred once, and after 15-25 days, the temperature is lowered to 25-30°C, the moisture content is reduced to 9-13%, and it is crushed into compost dry powder below 80 mesh, and the weight ratio is 68....

Embodiment 2

[0017] The method that present embodiment produces multi-element organic fertilizer with municipal solid waste is: earlier with artificial sorting of garbage, airflow sorting, magnetic separation and screening, mix 19.28% in the garbage of 80.68% by weight ratio, water content is 80-90% feces and cakes, then add 0.018% biocatalyst DBC, then add 0.022% deodorant EOC, spray water to adjust the water content to 35-45%, mix and stir evenly, pile up to 21 meters long, Strips with a width of 2.5 meters and a height of 2 meters are covered with a layer of fermented compost dry powder with a thickness of about 3cm on the surface. The air duct is opened to force ventilation into the pile, and the temperature of the center of the piled material is controlled at 75-85°C. Weekly Use a heap mixer to overturn and stir once, after 15-25 days, reduce the temperature to 25-30°C, reduce the moisture content to 9-13%, and crush it into compost dry powder below 80 mesh, with a moisture content of ...

Embodiment 3

[0019] The method of present embodiment to produce multi-element organic fertilizer with municipal solid waste is: first artificially sorting garbage, airflow sorting, magnetic separation and sieving, and mixing 23.96% moisture content of 80% into 76% garbage by weight ratio -90% feces and cakes, then add 0.015% biocatalyst DBC, then add 0.025% deodorant EOC, spray water to adjust the water content to 35-45%, mix and stir evenly, and pile up to 21 meters long and 2.5 meters wide m, strips 2 meters high; cover the surface layer with a layer of fermented compost dry powder with a thickness of about 3cm, open the air duct, force ventilation into the pile, control the temperature of the center of the piled material at 75-85°C, and pour it into the pile every week The mixer is turned over and stirred once, and after 15-25 days, the temperature is lowered to 25-30°C, the moisture content is reduced to 9-13%, and the compost dry powder is crushed into 80 mesh or less, and the water co...

Abstract

The present invention relates to organic fertilizer produced with urban domestic garbage. It is produced with urban domestic garbage as main material and through manual sorting, airflow sorting, magnetic selecting, sieving, adding dilute dung and cake dreg, adding biological catalyst DBG, adding deodorizer EOC, regulating water content, aerobic fermentation, drying and crushing to produce compost powder, adding nitrogen fertilizer, phosphate fertilizer and potash fertilizer, adding trace elements, mixing, granulation and stoving. The pollution-less polyelement organic fertilizer has comprehensive nutrients and is suitable for various kinds of soil.

Description

technical field [0001] The invention relates to a production method and a product thereof for producing multi-element organic fertilizers from urban living garbage. Background technique [0002] An invention patent disclosed in Chinese patent documents is titled "Method and product for producing microbial fertilizer from municipal solid waste". The preparation method of the fertilizer is: firstly add the bacterial culture of Pseudomonas PF-5 or H10 to the garbage, add water, compost and ferment, sort, sieve, remove sundries, dry and pulverize into garbage dry powder, Then add nitrogen-fixing bacteria culture, phosphorus-solubilizing bacteria culture, potassium-solubilizing bacteria culture or bacteria culture that can produce auxin and sugar solution to the dry garbage powder, and then add water and make it into granules. Finally, it is fermented and dried. The processing process has the following disadvantages: the nitrogen-fixing bacteria, phosphorus-solubilizing bacteri...
