Kitchen waste compost method using germ bran as conditioner

Abstract

The invention discloses a dining cabinet waste compost method taking germ bran as conditioner, belonging to waste resource utilization in the environment field. The method comprises the following concrete steps that: dining cabinet wastes are crushed and then germ bran is evenly mixed into the dining cabinet wastes with the ratio between the dining cabinet wastes and the germ bran of between 1:0.5 and 1:5; other conditioner or transformation promoter are added; the water content of the mixed materials is adjusted to between 55 and 65 percent, while C/N is adjusted to between 20:1 and 30:1 and pH is adjusted to between 7 and 8; meanwhile, the particle size of the materials is not more than 3 cm; and aerobic compost process is adopted to carry out compost treatment. Compared with the prior compost method, the compost speed of the method is faster by 3 to 10 days, and the method has less odor generation and nitrogen loss and stable final products; moreover, a plurality of products can be made according to different requirements, thereby saving a large amount of energy source and manpower.

Description

technical field [0001] The invention belongs to the direction of resource utilization of waste in the environmental field, and in particular relates to a method for composting kitchen waste using fungus chaff as a conditioner. Background technique [0002] Food waste refers to the food waste and residues produced by families, schools, government canteens and catering industry, and is the main component of urban domestic waste. At present, the proportion of kitchen waste in municipal solid waste continues to increase, accounting for 30% to 40% of municipal solid waste. Due to its high moisture content and low calorific value, food waste is not easy to be treated by ordinary landfill and incineration; Recycle raw materials. Composting food waste can not only eliminate its pollution to the environment, but also can be used as fertilizers and soil improvers. [0003] However, due to the high oil content, water content and high salt content of food waste, it is not conducive t...

Problems solved by technology

With the continuous development of my country's edible fungus industry, a large amount of fungus chaff has accumulated, which not only pollutes the surrounding water and soil, but also seriously interferes with the healthy operation of the edible fungus industry.

[0005] At present, some researchers have carried out research on the separate composting of kitchen waste or fungus chaff, such as the Chinese patent "Method of Converting Kitchen Waste into Fertilizer" (CN 1858027A), Chinese patent "A Kind of Edible Fungus Chaff "Green Fertilizer" (CN 1785923A), etc., but the previous methods are more complex, such as sterilization and other steps are required, and there is no report on the use of bacterial chaff as a conditioning agent for composting food waste
