1 Collectively collect the domestic garbage from each district into the domestic waste fermentation processing plant. The garbage fermentation treatment plant should be located in the suburbs, and the lower air outlet is more than 2 kilometers away from the residential area.
2 Before the sorting process, the municipal solid wastes are sorted and recycled for recyclable materials, such as renewable plastics, metals, waste paper, glass, etc.; the sorted combustibles are incinerated; the sortable rotten organic wastes are sorted It is used for fermentation treatment, and the organic waste after treatment produces organic fertilizer; inorganic waste can be used for landfill, paving or for soil modification (fine inorganic waste).
In the sorting process, special attention is paid to the separation of metal chips. If the metal objects cannot be completely separated, the crushing equipment will be damaged during the post-fermentation pulverization process.
3 Fermentation Process 1 Basic Principle Through the action of microbial strains, the crude fiber and crude protein in organic waste can be fully decomposed to achieve harmlessness and decomposing, and organic fertilizer can be produced to provide organic fertilizer for agriculture. Organic waste comes from nature and belongs to nature, thus protecting the ecology of nature. The process can adopt rapid aerobic fermentation, high temperature and post-corrosion, and the treatment period is 7-10 days.
Fermentation process 1 Raw materials blending Domestic organic waste includes: toilet waste, kitchen waste, animal fur, leather dust, mushroom residue, urban living sludge... These are often low in water content, which makes it difficult to ferment, which needs to be added. Other wastes with higher water content are mixed and fermented. Generally, biogas residue, domestic sludge, etc. can be used to improve nutrient, organic matter and moisture content. Raw material ratio is 1:1
2 Strain dilution and treatment The fermented bacteria and excipients with good weighing are stirred evenly in a ratio of 1:5 (the purpose is only to expand the volume of the bacteria, so that it can spread evenly on the raw materials).
3 Stirring of raw materials and addition of strains The diluted strains are added to the bio-waste fermentation raw materials and stirred evenly. The water content of the fermented materials should be controlled at about 60% (hands can be broken into groups, loosened and cracked at least guaranteed) Do not use your hands to drip between the fingers.)
4 The pile body is required to stack the stirred fermented material, the height is about 1.2m, the width is at least 2-3m, and the length is not limited.
5 Fermentation time fermentation for 24-28 hours, the temperature can be over 55 °C, the deodorization effect can be achieved two days after the temperature rise, stacking fermentation for 7-10 days, (the period can be properly turned over several times), can be made into biological organic fertilizer use.
4 After the fermentation of the deep-processed raw materials is completed, the powdered organic fertilizer is prepared by moderately crushing. If you are producing powdered organic fertilizer or high-content organic-inorganic compound fertilizer, you need to introduce equipment such as pulverizer, granulator and dryer.

Production of organic fertilizers from domestic waste (organic waste)
Domestic waste generally refers to solid waste generated in activities that are performed in daily life or for daily life. The domestic garbage for producing organic fertilizer mainly refers to leftovers, vegetable leaf peel, rotted melons, animal internal organs, snacks and other food waste, as well as crop straw, dead branches, chaff, bamboo shoots, and defective Fruit and animal droppings, etc. Other household waste such as paper dust, plastic, metal, glass, etc. may be mixed during the period.
