Embodiment 1

[0029] Step 1: Pour the recovered food waste into the vibrating sieve to remove miscellaneous sorting, sift out plastic skins, bottles, wooden chopsticks and other sundries in the food waste, and then enter the centrifugal solid-liquid separator for solid-liquid separation Separation, throwing out the waste water and oil, pouring the oily waste water into the oil-water separator for oil-water separation, the separated waste water is used as the water source for sintering brick factories or boilers for smoke and dust removal, adding waste engine oil to the waste oil to make fuel oil, Solid food waste with a remaining water content not greater than 80%;

[0030] Step 2: Pour the solid food waste obtained in step 1 into a pulverizer for crushing treatment, and then put it in a drying room for drying. Drying uses boiler heat or waste heat from power plants, cement factories, and sintered brick factories as a heat source, and the rotation can be adjusted. Drying is carried out on a...

Embodiment 2

[0033] Step 1: Pour the recovered food waste into the vibrating sieve to remove miscellaneous sorting, sift out plastic skins, bottles, wooden chopsticks and other sundries in the food waste, and then enter the centrifugal solid-liquid separator for solid-liquid separation Separation, throwing out the waste water and oil, pouring the oily waste water into the oil-water separator for oil-water separation, the separated waste water is used as the water source for sintering brick factories or boilers for smoke and dust removal, adding waste engine oil to the waste oil to make fuel oil, Solid food waste with a remaining moisture content of no more than 75%;

[0034] Step 2: Pour the solid food waste obtained in step 1 into a pulverizer for crushing treatment, and then put it in a drying room for drying. Drying uses boiler heat or waste heat from power plants, cement factories, and sintered brick factories as a heat source, and the rotation can be adjusted. Drying on a fast chain p...

Abstract

A material composition for preparing an organic fertilizer from kitchen garbage is disclosed. The material composition comprises following raw materials by mass: 20-95% of kitchen garbage powder, 3.5-50% of straw powder, 1-30% of humic acid powder, and 0.5-1.5% of lactic acid bacteria powder, with the sum of the mass percentages of the raw materials being 100%. A preparing method of the organic fertilizer includes: subjecting recovered kitchen garbage to impurity removal, sorting, performing solid liquid separation to obtain solid state kitchen garbage with a low water content, smashing the solid state kitchen garbage, drying to obtain the kitchen garbage powder, adding the straw powder, the humic acid powder and the lactic acid bacteria powder into the kitchen garbage powder, and fully stirring. By the material composition and the method, the problems, namely a high cost for kitchen garbage treatment and transportation and liable pollution to the environment, are overcome, and the organic fertilizer manufactured can be absorbed by crops and prevents soil hardening caused by over fertilization, thus turning harm to good, turning waste materials into things of value, and achieving recycling and reutilization of the kitchen garbage.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, and relates to a material composition for making organic fertilizer by using kitchen waste, and also relates to a method for making organic fertilizer by using kitchen waste. Background technique [0002] At present, most of the food waste collected from government stoves, restaurants, hotels, etc. will be collected to the disposal plant, through solid-liquid separation, oil-water separation, and the separated food waste will be put into a closed container for anaerobic fermentation, and the biogas produced It is used to burn boilers, generate electricity, etc. Biogas slurry and biogas residue are sent to fertilized farmland. Due to the large amount of garbage generated in cities above the middle level, multiple large-volume containers are required, which occupy a large area of ​​land and take a long time to ferment. It is not suitable for storage. In cold regions, thermal ...
