[0034] according to figure 1 The process shown is for the treatment of kitchen waste.
[0035] In this example, the kitchen waste has a water content of about 85%, a carbon-to-nitrogen ratio of 8, and an oil content of 15%.
[0036] First, the kitchen waste is cleaned with water to obtain a mixture of oil and water and solid waste. In the cleaning step, the water of 1 / 3 of the mass of kitchen waste is used for cleaning three times. The oil-water mixture is separated by filtration to obtain waste oil and waste water. Among them, the waste oil can be used for aviation fuel, and the reused water obtained from the waste water after reverse osmosis is used to clean kitchen waste, and the waste is only a small amount of concentrated liquid.
[0037] Crush 2kg of solid waste, then add 2kg of fir chips with a particle size of 0.1-0.2mm, then add 200mL of bacterial liquid, and perform aerobic composting in an oil bath (oxygen nat...
