Problems solved by technology

Incineration mainly involves energy consumption and secondary pollution such as dioxin pollution; the landfill method is limited by available land resources, and site selection is difficult, and the cost of preventing landfill gas and leachate pollution is high; feed Poor control will endanger human health through the food chain, such as waste oil, garbage pigs, etc.; the main problem of anaerobic fermentation is methane control, which is very prone to explosion, causing safety concerns

Embodiment 1

[0033] Embodiment 1, the treatment of kitchen waste

[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...

Abstract

The invention discloses a microorganic aerobic composting method of kitchen garbage. The microorganic aerobic composting method comprises the following steps: water is used for cleaning kitchen waste so as to obtain an oil-water mixture and solid garbage; wood chips and alicyclobacillus are added into the solid garbage, and then aerobic composting is carried out so as to obtain a composting product. According to the invention, reducing, harmless and resourceful treatment to kitchen waste is carried out by adopting a microbic aerobic composting way. According to the invention, oil-water separation and reverse osmosis water treatment methods are adopted for treating kitchen waste, so as to reduce oil components in the kitchen waste and improve the composting effect, and the water resource reutilization is achieved. In the aerobic composting treating process, carbon-nitrogen ratio and water content are adjusted by adding cunninghamia lanceolata chips, the high-temperature-resistant and acid-proof alicyclobacillus are used, during linked optimization processes of heating, stirring and time controlling, energy conservation is achieved, the treatment efficiency is improved, the composting product meeting national standards and industrial standards is produced, and requirements of environment protection and sustainable development are met.

Description

technical field [0001] The invention relates to a method for microbial aerobic composting of kitchen waste. Background technique [0002] Kitchen waste belongs to organic waste, which is divided into cooked kitchen waste and raw kitchen waste. Cooked kitchen waste includes leftovers, leftovers and vegetable leaves, etc.; raw kitchen waste includes fruit peels, egg shells, tea residue, bones and shells etc. Kitchen waste generally refers to the source raw materials and finished products (cooked food) or residues required in family life and diet. [0003] There are several ways to deal with kitchen waste at home and abroad: incineration, landfill, feed, anaerobic fermentation, and aerobic composting. Incineration mainly involves energy consumption and secondary pollution such as dioxin pollution; the landfill method is limited by available land resources, and site selection is difficult, and the cost of preventing landfill gas and leachate pollution is high; feed Poor contr...
