example 1

[0038] Preparation of secondary isolates:

[0039] 1) Livestock and poultry waste water is poured into the regulating tank, and then 0.01-3% of additives are added according to the weight percentage for aeration and stirring. At the same time, ultrasonic treatment is used. The ultrasonic frequency range is 20-100kHZ, and the ultrasonic intensity range is 0.1-70W / cm 2 , Ultrasonic response time 0.1 ~ 60min. The auxiliary agent is one or a mixture of deodorants and microbial regulators.

[0040] Ultrasonic treatment preferably has an ultrasonic frequency of 40kHZ and an ultrasonic intensity of 40W / cm 2 , Ultrasonic response time is 3min.

[0041] (2), the waste water of the regulating tank after the treatment of step (1) is separated through a grid coarse sieve, and large particles are removed to obtain a primary isolate. The waste water of the regulating pond is injected into the separation tank, and 0.01~ 3% of the auxiliary agent is aerated and stirred for aerobic treatmen...

[0064] Preparation of secondary isolate step is the same as in Example 1

[0065] The preparation of bio-organic fertilizer consists of the following components:

[0066] 25kg of secondary isolate, 69kg of mushroom dregs, 3kg of bacteria agent for the first fermentation, and 3kg of bacteria agent for the second fermentation.

[0067] Make the first fermentation bacteria agent:

[0068] Inoculate Bacillus cereus in LB medium and culture in a test tube at a culture temperature of 25-35°C and a culture time of 36-60 hours;

[0069] The Bacillus cereus cultured in the test tube is transferred to a 1000ml shake flask for culture, the culture temperature is 22-35°C, the rotation speed is 160-200 rpm, and the culture time is 24-48 hours;

[0070] Then, the Bacillus cereus cultivated in the shake flask is inserted into the seed tank for cultivation, the cultivation temperature is 25-35° C., and the cultivation time is 24-48 hours;

[0071] After being cultivated in the seed tank, t...

[0086] 40kg of secondary isolate, 56kg of straw powder, 2kg of bacteria agent for the first fermentation, and 2kg of bacteria agent for the second fermentation.

[0087] Make the first fermentation bacteria agent:

[0088] Inoculate Bacillus cereus in LB medium and culture in a test tube at a culture temperature of 25-35°C and a culture time of 36-60 hours;

[0089] The Bacillus cereus cultured in the test tube is transferred to a 1000ml shake flask for culture, the culture temperature is 22-35°C, the rotation speed is 160-200 rpm, and the culture time is 24-48 hours;

[0090] Then, the Bacillus cereus cultivated in the shake flask is inserted into the seed tank for cultivation, the cultivation temperature is 25-35° C., and the cultivation time is 24-48 hours;

[0091] After being cultivated in the seed tank, the...

Abstract

The invention relates to a method for preparing a biological organic fertilizer by utilizing wastewater separate substances of livestock and poultry, in particular to a method for preparing a biological organic fertilizer by utilizing wastewater of livestock and poultry and functional microbes and application of the biological organic fertilizer, and belongs to the technical fields of novel organic fertilizers and the recycling of agricultural wastes. According to the method, microbial inocula which are prepared from pseudomonas fluorescens, bacillus cereus and erwinia mitsuencis which serve as functional strains are added into organic wastes such as rotten bran, straw powder and mushroom dregs to be rotten and fermented to prepare the organic fertilizer. According to the method, the organic fertilizer is prepared by utilizing the wastewater of the livestock and poultry, so that the wastes are recycled; and the preparation method is simple and convenient, and is easy to popularize and apply in fertilizer industry.

Description

technical field [0001] The invention relates to a method for preparing bio-organic fertilizer from livestock and poultry wastewater separation, in particular to a method for preparing organic fertilizer by mixing livestock and poultry wastewater separation with organic waste and functional microorganisms, and belongs to the technical field of new organic fertilizers and Agricultural waste resource recycling technology field. Background technique [0002] The biogas slurry of livestock and poultry wastewater contains nutrients needed for plant growth, less inventory of pathogenic microorganisms, and is rich in organic matter that is beneficial to soil improvement and small molecule humus that is easy for plants to absorb. Biogas residue and biogas slurry are of positive significance to the improvement of crop yield and quality, and are also conducive to the maintenance and improvement of soil fertility. Therefore, fertilizer use is currently the most important way to use biog...
