Embodiment 1

[0041] Bacteria are mixed and added to the fermenter according to the mass ratio content, composting Bacillus 25%, Geobacillus stearothermophilus 25%, Aerobacillus paleus 25%, Psychrobacter faecalis 10%, Geobacillus thermodenitrophilus Bacillus 15%. Proportioned into a compound microbial agent. Mix the compound microbial agent according to 1kg strain / 3m 3 If the litter volume ratio is added to the ectopic fermentation bed, the amount of bacterial agent added to a single tank is 69kg, and the volume of manure added to each tank is about 4m3 per day. Among them, the construction scale of the fermenter for this test is 45m in length, 3.85m in width, 1.7m in wall height, 40m in length, 1.4m in litter height, and 3.85m in width. 207m3.

[0042] Measuring results: refer to Table 1 to observe the temperature of the fermentation tank within 20 days. The results show that after adding the compound microbial bacterial agent and adding manure to the litter in Example 1, the amount of ...

Embodiment 2

[0044] Repeat Example 1, and Example 2 has the following differences, which are mainly reflected in the differences in the composition of the compound bacterial agent: 25% of composting bacillus in situ, 25% of Geobacillus stearothermophilus, 20% of Aerobacillus pallor, 20% of feces 10% Psychrophilic Bacillus, 20% Thermodenitrophilic Geobacillus.

[0045] Measuring results: refer to Table 1 to observe the temperature of the fermenter within 20 days. The results show that the temperature in the fermenter in Example 2 can rise to the start-up temperature (55°C) on the fourth to fifth day, and measure 55.2°C on the fourth day. Example 1 Add about 4m3 of feces every day under the same operating conditions. During the observation period of 20 days, there is no obvious irritating smell in the ectopic fermentation house. On the 10th day, droplet sewage began to seep out of the backflow tank until 14 days The first measurement of the return flow of sewage in the reflux tank was 0.5m3,...

Abstract

The invention particularly relates to a compound fermentation agent in an ectopic fermentation treatment system of livestock and poultry manure. The compound microbial agent for treating manure by ectopic fermentation is composed of the following strains: Geobacillus toebii, Geobacillus stearothermophilus, Aeribacillus pallidus, Psychrobacter faecalis and Geobacillus thermodenitrificans. The compound agent is applied to an ectopic fermentation bed and has the advantages of rapid low-temperature start property, high fermentation temperature, high manure decomposition speed, large water volatilization amount and the like, and defects of low manure decomposition efficiency and high padding consumption rate of an existing microbial agent are overcome.

Description

technical field [0001] The invention specifically relates to a composite fermentation bacterial agent in a livestock and poultry manure ectopic fermentation treatment system, and belongs to the field of breeding manure environmental protection. Background technique [0002] With the structural adjustment of the animal husbandry industry and the advancement of agricultural industrialization, the large-scale and intensive livestock and poultry breeding industry has developed rapidly, and the animal husbandry and breeding industry has become one of the important pillar industries of the people's livelihood economy. However, due to the weak management of the livestock and poultry breeding industry, the lack of environmental protection concepts, and the lagging behind of my country's environmental protection technology, a large amount of livestock and poultry feces pollutants are discharged and lost randomly, causing serious pollution to water, soil, air, etc., and affecting the l...
