Problems solved by technology

The first method has obvious seasonality, the second method seriously pollutes the environment during the drying process, and these two methods are very likely to cause crop burnt; the third method is better, but the fermentation time is longer, Nutrient loss is high, and the compost quality is unstable, and the odor pollutes the environment, which is not conducive to the large-scale production and industrial operation of organic fertilizers; at present, there is another method for quickly processing chicken manure, which uses 80-100 °C ultra-high temperature continuous strong Stirring to ferment the material, this method can complete the fermentation within 20 hours, but this method requires high equipment and consumes a lot of energy, resulting in high cost

Abstract

The invention discloses a method for preparing bio-organic fertilizer by utilizing quick odorless fermentation of chicken manure. The bio-organic fertilizer is prepared from microbial liquid inoculum, auxiliaries and chicken manure by means of two-step fermentation, and no foul smell, ammonia gas or other pollution gases is generated in the whole process. The bio-organic fertilizer is grayish brown odorless particles without mechanical impurities. By detection, in the bio-organic fertilizer, the content of lactic acid bacteria is more than or equal to 10<8>CFU/g, the content of total viable bacteria is more than or equal to 10<9>CFU/g, the content of organic matters is 57.67 percent, the content of total nutrient is 7.8 percent, no alive roundworm egg or pathogenic bacterium is contained, and the content of escherichia coli is less than or equal to 10<2>CFU/g, which is in accordance with the specification in the national standard of bio-organic fertilizer (NY 884-2012).

Description

technical field [0001] The invention relates to a production method of bio-organic fertilizer, in particular to a production method of preparing bio-organic fertilizer by rapid odorless fermentation of chicken manure. Background technique [0002] At present, domestic animal husbandry has developed rapidly. With the scale and intensification of chicken farming, the pollution of animal husbandry waste is also showing a trend of becoming more and more serious. It is more and more popular to develop animal husbandry and protect the environment. Pay attention to. According to surveys, a chicken farm with an annual output of 10,000 laying hens produces about 1.3 tons of chicken manure per day. Due to the high density of intensive poultry breeding, the house is humid; Farm environment, but also directly affect the growth and egg production rate of chickens, causing environmental pollution and waste of resources. According to the traditional composting method, it takes a lot of t...
