[0022] A treatment method for kitchen waste, comprising the steps of:

[0023] (1) Take the kitchen waste and put it into the cement pool, add water to the cement pool, the amount added is 50% of the mass of the food waste, let it stand for 10 hours, aerate oxygen from the bottom of the cement pool every 3 hours, and the aeration flow rate is 3kg / h, the aeration time is 20min;

[0024] (2) After the aeration is over, the materials in the cement pool are naturally air-dried until the water content is 65%, and the air-dried objects are collected. According to parts by weight, 60 parts of air-dried objects, 25 parts of citric acid, and 18 parts of Ammonium nitrite, 12 parts of carbamate and 8 parts of malic acid were put into a blender and stirred evenly, left to stand for 3 hours, and the standing mixture was collected;

[0025] (3) Mix the static mixture and pond silt with a water content of 80% in a mass ratio of 6:4, mix them evenly, put them into the cultivation pond, add ...

Abstract

The invention relates to a kitchen waste treatment method, and belongs to the field of waste treatment. According to the kitchen waste treatment method, abundant nutrient substances in kitchen waste and strains contained in the kitchen waste are utilized, an oxygenation mode is utilized to promote rapid propagation of the strains in the kitchen waste, and the decomposition efficiency of the wasteis improved; then citric acid and other substances are utilized to adjust the waste, and internal substances of the waste can be solidified, so that the loss of internal nutrient components is inhibited; and then a mixture is mixed with pond sludge, through the synergistic effect of microorganisms inside the pond sludge and microorganisms inside the kitchen waste, the waste is degraded, meanwhile,loaches and catfishes which are strong in life adaptability are used for decomposing, through the environment adaptability, the degradation of the kitchen waste is improved, and at the same time, formed small molecule organic matter settles in the sludge to form bottom mud containing the abundant nutrient components so that the bottom mud can be used as nutrient soils. The kitchen waste treatmentmethod has the advantages that secondary pollution is avoided, and reutilization of waste resources is completed.

Description

technical field [0001] The invention relates to a method for treating kitchen waste, which belongs to the field of waste treatment. Background technique [0002] With the rapid development of urban economy, society and people's life, the pollution of food waste to the environment and the harm of public health safety have become increasingly apparent. The harm of food waste has attracted great attention from people and the government. The construction of food waste treatment projects meets the needs of rapid urban development, meets the sustainable development of food waste treatment, improves the level of harmlessness, reduction and resource utilization of food waste, and can improve the collection and transportation of food waste status quo. [0003] At present, the main technologies of food waste treatment include landfill, incineration, anaerobic fermentation, aerobic composting, direct drying as feed and microbial treatment technology. Landfill technology has the chara...
