Abstract

The invention discloses a method for producing bio-organic fertilizers by quick fermentation of kitchen wastes. The bio-organic fertilizers are obtained by primary fermentation and secondary fermentation. Since primary fermentation products are partially returned to a fermentation matrix, fermentation rate is increased. According to characteristics of the kitchen wastes, yarrowia lipolytica, Saccharomyces willianus and bacillus laterosporus are selected for zymolysis of the kitchen wastes. Functional bacteria including streptomyces jingyangensis and the bacillus laterosporus are added, the streptomyces jingyangensis is capable of generating antibiotics to protect crops from pest and disease damages, and the bacillus laterosporus is resistant to high temperature, high salinity, dryness and high permeability and capable of improving soil salinity and alkalinity after being applied to soil and continuing decomposing macromolecular substances in the soil to provide nutrition for the crops, so that efficacies of the bio-organic fertilizers are improved.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a method for rapidly fermenting kitchen waste to produce bio-organic fertilizer. Background technique [0002] Food waste is a kind of organic solid waste mainly produced in food processing industry, restaurants, canteens and household kitchens. Perishable, smelly, easy to biodegrade and so on. In most cities in China, kitchen waste constitutes the largest part of municipal solid waste, accounting for 30%-50% of the total municipal solid waste. The daily output of food waste in China is astonishing, and the daily output of food waste in Beijing and Shanghai both exceeds 1,000 tons. So far, the most commonly used treatment method for food waste in my country is sanitary landfill, but this treatment method will not only produce leachate and greenhouse gases, but also occupy a large amount of valuable land resources. Under the restriction of increasingly stringent environmen...
