Problems solved by technology

At the same time, a certain amount of solid waste will also be produced in the industry. For example, in the production process of stevioside, a large amount of stevia slag will be left after the stevia sugar is extracted. These stevia slag will be sent to the garbage station, which will increase the garbage disposal The workload; the extraction of Chinese herbal medicine components will also bring a lot of Chinese herbal medicine dregs, and this part of Chinese herbal medicine dregs will be discarded

Embodiment 1

[0017] Catering waste is sorted to remove impurities to obtain food waste, which is crushed and added to Bacillus licheniformis, cereus Bacillus cereus, Bacillus magaterium, Paenibacillus larvae, Bacillus subtilis, Bacillus natto, Bacillus pumilus, thermophiles Bacillus stearothermophilus (Bacillus stearothermophilus), the total addition is 1% by weight of kitchen waste; add amylase, liquefaction enzyme, β-glucanase, neutral protease, cellulase, pectinase and lipase, add The amount is 0.01% (w / w); at the same time, add 10% wheat bran, mix and put it into the processing device, adjust the stirring speed to 20r / min, and adjust the temperature of the hot air to make the temperature of the material reach 50 °C for 6 hours, and then Adjust the temperature of the hot air again so that the temperature of the material reaches 65°C for 4 hours, and after drying at 80°C, the organic fertilizer is obtained by crushing.

Embodiment 2

[0019] After removing impurities from the slaughterhouse waste, after crushing, add Bacillus licheniformis (Bacillus licheniformis), Bacillus cereus (Bacillus cereus), giant Bacillus magaterium, Paenibacillus larvae, Bacillus subtilis, Bacillus natto, Bacillus pumilus, Bacillus stearothermophilus, The total amount of addition is 3% of the weight of organic waste in the kitchen; adding amylase, liquefaction enzyme, β-glucanase, neutral protease, cellulase, pectinase and lipase, the addition amount is 0.03% ( w / w); at the same time, add 8% rice bran, put into the treatment device after mixing, adjust the stirring speed to 15r / min, and adjust the hot air temperature so that the temperature of the material reaches 55°C for 5h, and then adjust the hot air temperature to make The temperature of the material reaches 70°C and is treated for 5 hours, dried at 80°C, and then crushed to obtain an organic fertilizer.

Embodiment 3

[0021] The organic waste obtained after removing impurities from the vegetable market garbage was crushed according to (1.2:1.2:1.0:1.4:1.2:0.7:1.2, v / v), and Bacillus licheniformis (Bacillus licheniformis), Bacillus cereus (Bacillus cereus), Bacillus magaterium, Paenibacillus larvae, Bacillus subtilis, Bacillus natto, Bacillus pumilus, Bacillus stearothermophilus ( Bacillus stearothermophilus) is added in an amount of 5% of the weight of organic kitchen waste; amylase, liquefaction enzyme, β-glucanase, neutral protease, cellulase, pectinase and lipase are added in an amount of 0.04% (w / w); at the same time, add 5% soybean meal, mix it and put it into the processing device, adjust the stirring speed to 30r / min, and adjust the temperature of the hot air so that the temperature of the material reaches 52°C for 7 hours, and then adjust the temperature of the hot air. Make the temperature of the material reach 75°C, treat for 5 hours, dry at 80°C for 3 hours, and then pulverize to...

Abstract

The invention relates to a process for treating solid organic waste resources (food residues, domestic garbage, vegetable market garbage, wastes and leftovers of slaughter houses and food products factories, beer lees, distilled spirit lees, stevia rebaudiana residues, Chinese medicinal herbal dregs and the like), which comprises the following steps of: removing impurities (plastic bags, bottle caps, napkins, metals and the like) from solid organic wastes; adding mixed bacteria, an enzyme preparation and auxiliary materials into the organic wastes; stirring the mixture and controlling the temperature by hot blast; performing fermentation treatment on the mixture by adopting a staged temperature raising method; and drying and crushing the mixture to obtain an organic fertilizer. The invention finds a process capable of effectively treating the solid organic wastes, which can convert the solid organic wastes into the organic fertilizer by using microorganisms to change the organic wastes into valuable and realize the recycling use and the quantity reduction of waste resources; besides, the used microorganisms are harmless to human and the ecological environment.

Description

technical field [0001] The invention relates to a process for treating solid organic waste resources, specifically, fermenting solid organic waste through microorganisms and enzymes to finally obtain organic fertilizers. Background technique [0002] At present, with the continuous growth of population, the improvement of living standards and the development of industry and agricultural economy, a large amount of solid organic waste is produced every day. If these solid organic waste is disposed of by landfill or incineration, it will endanger land resources. , The unpleasant gas produced pollutes the environment and wastes a lot of available resources. Among the generated garbage, most of the food waste, household waste and market waste are organic matter, which can be roughly divided into protein, starch, fat and cellulose, which are all natural organic matter. It is a pity that it is disposed of as waste. At the same time, a certain amount of solid waste will also be pr...
