Problems solved by technology

Some simple treatment methods for privately collected organic waste not only fail to effectively utilize organic waste, but even cause these organic waste to harm the society due to improper disposal. The most common way is to directly feed pigs with kitchen waste, and this garbage pig is Consumers eat it, seriously infringing on the interests of consumers; in addition, individual vendors have poor processing equipment, and directly emit a large amount of waste gas during the heating process, seriously polluting the atmospheric environment, and the waste water produced is directly discharged, polluting groundwater and soil, causing secondary pollution. pollution etc.

Abstract

The invention provides a green organic fertilizer produced from food waste and a preparation method thereof, and relates to the field of agriculture, in particular to a solid organic fertilizer and aliquid organic fertilizer produced from food waste and a preparation method thereof. The green organic fertilizer comprises the following raw materials in parts by weight: 85-90 parts of food waste, 5-10 parts of urea and 1-5 parts of modified rhodotorula glutinis. Innocent treatment of the food waste is conducted, specifically, fermentation treatment is conducted through special microorganisms, and the urban food waste is fermented and decomposed at high speed and finally becomes a green organic fertilizer.

Description

technical field [0001] The present invention relates to the field of agriculture. A green organic fertilizer produced from food waste and a preparation method thereof. Background technique [0002] As we all know, improper disposal of organic waste is one of the important causes of social and environmental pollution. For a long time, my country's urban waste treatment technology has been relatively extensive and lagging behind, which has caused many social problems. Some simple treatment methods for privately collected organic waste not only fail to effectively utilize organic waste, but even cause these organic waste to harm the society due to improper disposal. The most common way is to directly feed pigs with kitchen waste, and this garbage pig is Consumers eat it, seriously infringing on the interests of consumers; in addition, individual vendors have poor processing equipment, and directly emit a large amount of waste gas during the heating process, seriously pollutin...
