Embodiment 1

[0027] The preparation of the microbial composite bacterial agent that promotes pig manure composting fermentation of the present embodiment is as follows:

[0028] (1) Collecting samples: Pig manure and chopped rice straw were mixed at a mass ratio of 7:1 to form compost, which were collected at 30°C, 35°C, and 45°C during the compost heating period, and at 50°C, 55°C, and 57°C during the high temperature period. ℃, 59°C, and 57°C, 55°C, 50°C, 45°C, 35°C, and 30°C when the temperature started to drop, a total of 13 samples were taken from the compost, 10g of each sample was taken, and 100mL of sterilized In the triangular flask, add sterile water and glass beads to it at the same time, and shake it at a constant temperature for 30 minutes. The temperature set during the shaking of each sample is the compost temperature when the sample is taken;

[0029] (2) Preparation of gradient concentration dilution: take out the suspension after shaking each sample, and use it as 10 -1 ...

Abstract

The invention discloses a compound microbial agent for promoting fermentation of pig manure composting. The compound microbial agent is prepared from thermobifida fusca, ureibacillus thermophaericus, pantoea agglomerans, gibsonii, bacillus amyloliquefaciens, bacillus pumilus and a liquid culture medium. Compared with other treatment methods, the fermentation time of the compound microbial agent on the pig manure composting is shorter, and more obvious facilitation effect on fermentation of the pig manure composting is obtained.

Description

technical field [0001] The invention relates to the technical field of solid waste pollution control and resource utilization, and more specifically relates to a microbial composite bacterial agent for promoting pig manure composting fermentation. Background technique [0002] With the rapid development of scale and intensification of my country's livestock and poultry breeding industry, the environmental pollution caused by livestock and poultry manure is becoming more and more serious. It is estimated that China produces more than 3 billion tons of livestock and poultry manure every year, and livestock and poultry manure has become one of the three major non-point source pollution sources in my country. Generally, aerobic composting technology is commonly used to treat fecal pollution as a resource and become a usable organic fertilizer product. However, traditional composting generally has the disadvantages of long composting cycle and low composting quality. In order to...
