Abstract

The invention relates to a method for treating organic solid waste and bio-organic fertilizer prepared by using the method. The method comprises the steps: (1) mixing the wet material of the organic solid waste with crushed auxiliary materials so as to obtain a mixture with a water content of 45-55%; (2) inoculating high-temperature degrading bacteria to the mixture obtained in the step (1), performing ventilation on the mixture so as to ensure a fully aerobic environment of the mixture, performing intermittent turning-mixing treatment, and maintaining the temperature of the mixture at 65-75 DEG C for high-temperature fermentation for 2-6 days so as to obtain an intermediate material; and (3) inoculating extreme thermophiles to the intermediate material obtained in the step (2), performingeven turning, performing ventilation on the intermediate material so as to ensure a fully aerobic environment of the material, maintaining the highest temperature of the intermediate material at 85-90 DEG C continuously for 2-6 days, and performing static fermentation on the material for 18-21 days. Compared with the prior art, the method has the advantages of high feasibility, simple operation,a short production cycle, high output and stable product quality, and a win-win situation of environmental protection and economic benefits is achieved.

Description

technical field

[0001] The invention belongs to the technical field of organic solid waste treatment and resource utilization, and in particular relates to a method for treating organic solid waste and the prepared bio-organic fertilizer. Background technique

[0002] There are more than 10 billion tons of solid organic waste in my country every year. If the rich organic matter and plant nutrients can be converted into organic fertilizers, the potential for improving the recycling rate of resources will be huge. Traditional aerobic fermentation is the process of converting organic matter in organic materials into more stable humus, and the products are organic fertilizers and soil conditioners. The traditional process is simple to operate and requires less investment, but it has many problems, such as a large area, a long production cycle (about 1-2 months or even longer), high labor costs, greatly affected by geographical and climatic conditions, and prone to secondary prod...
