Method for preparing biological organic fertilizer through biodegradation of household refuse

Abstract

The invention discloses a method for preparing biological organic fertilizer through biodegradation of household refuse. The method comprises the following steps: fully mixing household refuse with water content of 50 to 65% and a Tianyuan biological starter according to a weight ratio of 1000: 2.5; and then adding chicken manure in proportion, carrying out full mixing and putting the obtained mixture into a fermentation tank for fermentation, wherein overturning operation is carried out during fermentation, fermentation is terminated when temperature drops to 30 DEG C from 60 to 70 DEG C, and a fermentation period is 35 to 45 d. The invention has the following advantages: the method is designed according to the plantation period of non-edible plants, and organic matters in refuse are rapidly degraded by using microbes; a nutrient release period is prolonged; the utilization rate of refuse is increased; and an added microbial preparation can improve disease resistance and stress resistance of plants, promotes root prosperity, improve fertilizer absorption capability of plants, reduce soil hardening and enhancing the ecological environment of soil.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizer production, in particular to a method for preparing bio-organic fertilizer by using biodegradable household garbage. Background technique [0002] For many years, the fertilizers used in gardens, green land, and afforestation are mainly fermented animal manure, straw, and urban domestic sludge; the main problems are: 1. Increase production costs; 2. Waste limited agricultural resources; 3. Fertilizer efficiency Slow and short; 4. The rate of improvement to the ecological environment is poor. [0003] In recent years, with the construction of urban-rural integration, the difference between urban and rural areas has become smaller and smaller, and the problem of domestic waste disposal has become more and more urgent. In addition to sorting out recyclable (such as metal, plastic, glass, paper) 10% to 20% and non-recyclable Recycled garbage is compressed (15% to 20%), and nearly 60% t...

Problems solved by technology

[0002] For many years, the fertilizers used in gardens, green land, and afforestation are mainly fermented animal manure, straw, and urban domestic sludge; the main problems are: 1. Increase production costs; 2. Waste limited agricultural resources; 3. Fertilizer efficiency Slow and short; 4. Poor rate of improvement to the ecological environment

[0003] In recent years, with the construction of urban-rural integration, the difference between urban and rural areas has become smaller and smaller, and the problem of domestic waste disposal has become more and more urgent. In addition to sorting out recyclable (such as metal, plastic, glass, paper) 10% to 20% and non-recyclable Recycled garbage is compressed (15% to 20%), and nearly 60% to 75% of organic waste is in urgent need of treatment. Scientific practice shows that domestic waste contains organic matter, N, P and other nutrients needed for plant growth. However, if the garbage is used directly, it will not only lead to environmental degradation, but also the bacteria in the garbage will compete with the plants for nutrients and cause them to infect and die. At present, domestic garbage is mainly landfilled, which will not only take up a lot of land resources, but also affect the groundwater and The environment will cause irreversible damage, and domestic waste resources will be greatly wasted
