preparation example Construction

[0012] The invention provides a method for preparing bio-organic fertilizer, which is characterized in that the method comprises mixing sludge, plant waste and high-temperature-resistant aerobic bacteria, and stacking and fermenting the obtained mixture until the moisture content of the mixture is reduced to 40% by weight % or less, such as 30-40% by weight, and then post-ripen the stacked fermented product, wherein the weight ratio of the sludge to the plant waste is 1:0.3-2, preferably 1:0.5-1, Based on each kilogram of plant waste, the amount of the thermostable aerobic bacteria added is 125-250 million, preferably 150-200 million, and the temperature that the thermostable aerobic bacteria can tolerate is at least 50°C.

[0013] According to the present invention, the object of the present invention can be achieved as long as the thermostable aerobic bacteria can withstand at least a high temperature of 50° C. and are harmless to human body and environment. Preferably, the ...

Embodiment 1

[0035] Mix the sludge and cassava residues in a weight ratio of 1:1, and inoculate Bacillus subtilis (Guangzhou Huayuan Biotechnology Co., Ltd.) (about 125 million inoculations per kilogram of cassava residues), and stack them into three-dimensional trapezoidal stacks after mixing evenly (The area of ​​the upper bottom surface is 1×2m 2 , the area of ​​the bottom surface is 2×3m 2 , height is 1m) carry out stacking fermentation, turn over 2 times every day to keep stacking temperature to be about 60 ℃, stop turning over after 25 days, record the moisture content of this moment mixture to be 37% by weight. The method of natural ventilation was used to keep the stacking temperature at about 35°C for 7 days to obtain the bio-organic fertilizer. The technical indicators such as organic matter in the bio-organic fertilizer were measured, and the results are shown in Table 2.

Embodiment 2

[0037] Mix the sludge and straw according to the weight ratio of 1:0.3, and inoculate Bacillus natto (Guangzhou Huayuan Biotechnology Co., Ltd.) (about 250 million cassava residues per kilogram), and stack them into three-dimensional trapezoidal stacks after mixing evenly (The area of ​​the upper bottom surface is 1×2m 2 , the area of ​​the bottom surface is 2×3m 2 , height is 1m) carry out stacking fermentation, turn over 2 times every day to keep stacking temperature to be about 60 ℃, stop turning over after 25 days, record the moisture content of this moment mixture to be 36% by weight. The method of natural ventilation was used to keep the stacking temperature at about 35°C for 7 days to obtain the bio-organic fertilizer. The technical indicators such as organic matter in the bio-organic fertilizer were measured, and the results are shown in Table 2.

Abstract

The invention discloses biological organic fertilizer and preparation method thereof. The method comprises the steps that sludge, plant waste and high temperature resistance aerobic bacteria are mixed; obtained mixture is conducted to stacking fermentation till the moisture content of the mixture is reduced to be lower than 40 percent by weight; then products conducted to stacking fermentation is conducted to after-ripening treatment, wherein the weight ratio of the sludge to the plant waste is 1:(0.3-2); by taking per kilogram of the plant waste as a reference, the additive amount of the high temperature resistance aerobic bacteria is 0.125 to 0.25 billion; and the high temperature resistance aerobic bacteria can tolerate at least 50 DEG C. The method adopts sludge and plant waste to prepare the biological organic fertilizer through fermentation, not only solves the problem of the difficulty in resource utilization of sludge and plant waste, but also solves the problem of the shortage of biological organic fertilizer, and has a broad application prospect; and the biological organic fertilizer is rich in organic matter and has high fertilizer efficiency and great economic and social benefits.

Description

technical field [0001] The invention relates to a preparation method of bio-organic fertilizer and the bio-organic fertilizer prepared by the method. Background technique [0002] Bio-organic fertilizer refers to a type of microbial fertilizer and organic fertilizer that is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. Fertilizer with fertilizer effect. Bio-organic fertilizer not only has high fertilizer efficiency and reasonable price, but also does not pollute the environment compared with chemical fertilizers. It is safe and efficient to use. The development and utilization of bio-organic fertilizer has attracted more and more attention from all countries. [0003] The sludge produced in the process of urban sewage treatment and industrial production is the main source of sludge. There are...
