Problems solved by technology

But no matter which kind of microbial complete fermentation method has the following technical shortcomings: 1. Most of the organic waste cannot be fully decomposed; 2. According to the previous fermentation method, the waste cannot be effectively processed in a short time to obtain compost. It is very difficult to deal with organic waste produced in large-scale industrial manufacturing processes such as large-scale agriculture, food processing industry and sludge; 3. Organic waste will more or less contain some heavy metals such as cadmium, mercury and arsenic Components, if the fermented compost contains these components, it cannot actually be used in crops; 4. The types and combinations of bacteria used are not sufficient, resulting in the ineffective recycling of organic waste and the generation of new Waste; 5. The peculiar smell of organic waste cannot be eliminated; 6. A large amount of carbon dioxide is produced through incineration or landfill

Embodiment 1A～1F

[0017] Mix small pieces of wood and rice husks at a mass ratio of 1:0.5 to obtain the base material used as a fungal bed, a total of 15.06kg, which is 30 times the daily processing capacity. Then add ferrous solution and mix well. Then put into the bacterial population (Sporocytophaga, Rhizopus nigricans, Streptomycetaceac, Pseudomonas, Aspergillus oryzae, Penicillium glaucum, photosynthetic bacteria Rhodopseudomonaspalustris, subtilis Bacillus subtilis, lactic acid bacteria, Candida Albicans), stir well. Add 500 g of sludge from a sewage plant to the above-mentioned parent material containing liquid ferrous iron and bacteria groups, and the moisture content of the sludge is 60%. The humidity of the base metal is between 20-30%, and the temperature is about 10-25 degrees. After 10 hours, check the base metal, and it can be found that a large amount of heat rises in the base metal, and the temperature of the base metal rises to 65 degrees. It can be confirmed by naked eyes an...

Embodiment 2

[0022] Mix small pieces of wood and rice husks at a mass ratio of 1:0.5 to obtain the base material used as a fungal bed, a total of 15.06kg, which is 30 times the daily processing capacity. Then add liquid divalent iron accounting for 20% of the mass of the base material, and mix the liquid divalent iron with a concentration of 5 ppm of the liquid divalent iron. Then put into the bacterial population (Sporocytophaga, Rhizopus nigricans, Streptomycetaceac, Pseudomonas, Aspergillusoryzae, Penicillium glaucum, photosynthetic bacteria Rhodopseudomonaspalustris, Bacillus subtilis Bacillus subtilis, lactic acid bacteria, Candida Albicans), the thalline accounts for 20% of the mass of the base material, and is stirred and mixed. Add 500 g of sludge from a sewage plant to the above-mentioned parent material containing liquid ferrous iron and bacteria groups, and the moisture content of the sludge is 60%. The humidity of the base metal is between 20-30%, and the temperature is about ...

Embodiment 3

[0025] Mix wood chips and sawdust at a mass ratio of 1:1 to obtain 15.06 kg of base material, which is 30 times the daily processing capacity. Then add liquid ferrous iron with a concentration of 5ppm, which accounts for 30% of the mass of the base material, and mix well. Re-enter the bacterial population (Sporocytophaga, Rhizopus nigricans, Streptomycetaceac, Pseudomonas, Aspergillus oryzae, Penicillium glaucum, photosynthetic bacteria Rhodopseudomonaspalustris, subtilis Bacillus subtilis, lactic acid bacteria, Candida Albicans), the thalline accounts for 25% of the mass of the base material, and is stirred and mixed. Add 500 g of sludge from a sewage plant to the above-mentioned parent material containing liquid ferrous iron and bacteria groups, and the moisture content of the sludge is 60%. The humidity of the base material is between 20% and 30%, and the temperature is about 10-25 degrees. After 10 hours, the base metal was inspected, and it was found that a large amount...

Abstract

The invention discloses application of divalent iron to promoting fermentation of floras for treating organic waste. The floras for treating organic waste comprise the following bacterial genera including cellulolytic decomposers, streptomyces, pseudomonas, eurotium, penicillium, rhodopseudomonas, lactobacillus acetotoleran, bacillus and saccharomycetes. The divalent iron in the application can accelerate decomposition and fermentation of the floras for treating the organic waste to the organic waste, the fermentation cycle is greatly shortened, and the volume reduction rate is increased.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to the application of divalent iron and a composition for treating organic waste. Background technique [0002] Organic waste refers to organic articles and substances that have lost their original use value or have not lost their use value but have been discarded or abandoned in production, life or other activities. At present, the amount of organic waste in the country is huge. If it cannot be disposed of in a timely, safe and effective manner, it will cause great harm to the society and form a secondary cycle of associated pollution. The traditional treatment of organic waste is mainly through microbial complete fermentation. The microbial complete fermentation method mainly includes three types: first, natural complete fermentation, which takes about 1 to 2 years; second, complete fermentation with reduced water content, which takes about 48 days; ...
