Abstract

The invention discloses a method for preparing a microbial organic fertilizer from kitchen wastes. The method comprises the following steps of (1) selecting kitchen wastes, agricultural and sideline product wastes, inorganic auxiliary materials and a microbial compound bacteria group; (2) carrying out dehydration, oil removal and desalination treatment on the kitchen wastes and agricultural and sideline product wastes; (3) mixing the dehydrated kitchen waste with dehydrated agricultural and sideline products; (4) adding the inorganic auxiliary material and the microbial compound bacteria groupinto a mixture for compost fermentation; (5) after the compost fermentation temperature reaches 50-60 DEG C, transferring into a trough type fermentation tank for trough type fermentation; and (6) screening a fermented material through a classifying screen to obtain the microbial organic fertilizer. According to the invention, the problems of environmental pollution and resource waste caused by the kitchen wastes are effectively solved, and the prepared microbial organic fertilizer has the characteristics of activating soil, increasing the organic matter content of soil and improving the comprehensive fertility level of the soil.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, in particular to a method for preparing microbial organic fertilizers from kitchen waste. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Food waste contains extremely high moisture and organic matter, which is easy to rot and produce bad smell. [0003] The proportion of food waste produced in China every year in urban waste is close to or exceeds 50%, but the resource utilization rate of food waste in my country is still very low. Still very low. Most of the food waste is still mixed with domestic waste and disposed of ...
