Problems solved by technology

[0010] Although the technical solutions disclosed above all use rural organic waste as the basic raw material to prepare solid organic fertilizers or liquid fertilizers, the added value of these products is not high, and the production process often smells heavy and the environment is dirty. It will also cause secondary pollution, especially for the organic waste of the liquid part, such as biogas slurry, squeezed liquid after solid-liquid separation, human and animal urine, etc., lack of effective deep processing and utilization of resources

Embodiment

[0037] A recycling method of organic waste, aimed at rural organic waste, the collection method is as follows: First, it is necessary to establish an organic waste collection system including the source classification of domestic waste to facilitate collection and transportation, and reduce production costs ; Then, after the organic waste is transported to the processing plant, it will be sorted through the conveyor belt foreign matter sorting system to remove foreign matter that cannot be fermented and decomposed, and the remaining organic waste that can be fermented and decomposed is the main body of treatment.

[0038]For organic waste from different sources, the rotten fruit of fruit and vegetable crops with a water content of more than 70%, such as rotten citrus, is mechanically crushed; the stems and waste materials of fruit and vegetable crops with a water content of less than 70% are mechanically crushed; After separation, mechanical crushing, solid-liquid separation to...

Abstract

The invention provides a recycling treatment method for organic wastes. The recycling treatment method comprises the following steps: carrying out mechanical pulverization; carrying out aerobic fermentation on solid residues, and carrying out aerobic and anaerobic intermittent fermentation on liquid filtrate; a fermentation solid product is used to cultivate earthworms or black soldier flies; manufacturing powdery biological organic fertilizer by earthworm faeces or black soldier fly faeces; carrying out flocculation, purification and concentration on a fermentation liquid product; and concentrating nutrient solution to manufacture organic nutrition liquid fertilizer. According to the recycling treatment method, the recycling utilization ratio of the organic wastes can be improved, secondary pollution is lowered, and a product additional value is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to a treatment method of organic waste, in particular to a resource treatment method of organic waste. [0003] 【Background technique】 [0004] my country is a country with a small amount of resources per capita and a fragile ecological environment. The current economic development mode is still dominated by the traditional model of high consumption, high pollution and low output. Insufficient resources and environmental pollution have become constraints to my country's economy and development. An important factor of social development, such national conditions determine that economic development must take the road of circular economy with comprehensive utilization of resources, which is an inevitable choice for my country to achieve sustainable development strategy. [0005] With the development of my country's economy and society, people's living standards have improved significantly. Rotten fruits and vegetables, crop st...
