Abstract
The invention discloses a method for preparing organic fertilizer on the basis of urban household garbage. The method comprises the following steps that organic materials selected from the urban household garbage, auxiliary materials and microbial fermentation strains are evenly mixed in a biological organic fertilizer fermentation tank, standing is conducted for 24 h at room temperature, turning over of materials is conducted for 1-3 times at the temperature ranging from 40 DEG C to 55 DEG C, ventilation is conducted for 1-4 h, and standing is conducted for 22-25 h; continuous fermentation is conducted for 14-18 days at the temperature ranging from 55 DEG C to 65 DEG C till the mixture does not have a foul smell, the water content of the whole system is adjusted to 35 wt%, the temperature is adjusted to below 40 DEG C, and the mixture can be taken out from the tank, wherein turning over of the mixed materials is conducted once every other day. According to the method for preparing the organic fertilizer on the basis of the urban household garbage, degradation treatment on the urban household garbage is thorough, the environmental protection problem brought by the urban household garbage is solved, and large-scale production can be achieved.
