Embodiment 1

[0021] The high-efficiency compound microbial agent for rapid deodorization and nitrogen fixation is composed of Bacillus licheniformis, Bacillus megaterium, Lactobacillus acidophilus, Saccharomyces cerevisiae, nitrogen-fixing bacteria Brown Globe, and Streptomyces griseus. The ratio of various microorganisms is Bacillus licheniformis: gigantic Bacillus : Lactobacillus acidophilus : Saccharomyces cerevisiae : Azotobacter phenus : Streptomyces griseus = 5:3:3:4:2:2.

[0022] The bacterial species is cultivated by the following method: the bacterial agent is cultured on a primary slant, a primary shake flask, and a secondary shake flask in sequence, and then the bacteria are transplanted into a solid medium at a room temperature of 35° C. for 96 hours.

[0023] When in use, the cultured high-efficiency complex microbial flora is inoculated and colonized with biological fillers in a special container at a temperature of 35°C, and the fillers are placed in the excrement storage tan...

Embodiment 2

[0026] The high-efficiency compound microbial agent for rapid deodorization and nitrogen fixation is composed of Bacillus licheniformis, Bacillus megaterium, Lactobacillus acidophilus, Saccharomyces cerevisiae, Azotobacter sphaeroides, and Streptomyces griseus. The ratio is Bacillus licheniformis: Bacillus megaterium: Lactobacillus acidophilus: Saccharomyces cerevisiae: Azotobacter phenus: Streptomyces griseus=5:3:3:4:2:2.

[0027] The culture method of bacterial agent is with embodiment 1.

[0028] Put the fresh pig manure in the fermentation tank, add sawdust according to the weight ratio of 35% and mix evenly, adjust the water content to 45%, and obtain the pretreated material. At 35°C, the above-mentioned microbial agent was added to it with an inoculation amount of 5% by weight, stirred regularly, and fermented for 7 days, the water content was reduced to about 20%, and the nitrogen loss was reduced by 22% (compared with the blank group control).

Abstract

The invention provides a microbial fermentation bacterium capable of rapidly removing odor and fixing nitrogen used for treating human and animal feces. The microbial fermentation bacterium is composed of bacillus licheniformis, bacillus megatherium, lactobacillus acidophilus, a brewer's yeast, azotobacter chroococcum and streptomyces griseus. The microbial inoculum has the capacity of inhibitingthe growth and propagation of rot pathogens, and can achieve the deodorization effect for stink substances from the source, so that the harm caused to the human body by the pathogens can be reduced. For the microbial inoculum, the number of effective viable bacteria is high, when the materials of the same amount are treated, the feeding amount of the microbial inoculum can be reduced, thus the treatment cost for the feces can be greatly reduced, and the microbial fermentation bacterium can be widely applicable to immobile or movable toilets. After the microbial inoculum is inoculated to a feces storage box, the effects of rapidly removing odor and efficiently degrading the human and animal feces can be achieved, the feces can be degraded to form liquid within a short time, the maximal harmlessness and minimization of the feces are realized, and the policy of sustainable development is conformed.

Description

technical field [0001] The invention belongs to the field of ecological environment protection, and relates to a rapid deodorizing and nitrogen-fixing microbial fermentation bacterium for treating human and livestock feces. Background technique [0002] Because feces contain a large amount of organic matter, they will produce foul-smelling poisonous and harmful gases such as mercaptan, sulfide, ammonia, and hydrogen sulfide after rotting and decomposing. Moreover, their odor will increase exponentially with time in a certain period of time, seriously polluting the air and affecting the toilet. Therefore, in the process of manure treatment, there is an urgent need for a treatment process that can quickly and effectively eliminate odor. Microbial deodorization technology is a new deodorization technology developed in the 1950s. It uses the physiological metabolic activities of microorganisms to degrade odorous substances and oxidize them into odorless and harmless final produc...
