Low-temperature-resistant composting fermentation microbial inoculum with deodorizing function and applications of low-temperature-resistant composting fermentation microbial inoculum

Abstract

The invention discloses a low-temperature-resistant composting fermentation microbial inoculum with a deodorizing function and applications of the low-temperature-resistant composting fermentation microbial inoculum. The microbial flora contained in the low-temperature-resistant composting fermentation microbial inoculum provided by the invention can tolerate low temperature, and can normally grow at 15-20 DEG C, so that the fermentation air temperature of organic materials in the low-temperature environment is facilitated, in addition, the strains have the mutual promotion effects, therefore, a mutual synergistic effect is generated, and further, decomposing is accelerated. The experiment proves that during the composting process, after the low-temperature-resistant composting fermentation microbial inoculum is added into the organic materials for fermentation, the sum of effective microbes at the composting initial stage is improved, the temperature increase rate of the composted materials is accelerated, the anaerobic fermentation time is shortened, the decomposing process is accelerated, meanwhile, the discharge of sulfur-containing compounds and nitrogen-containing compounds is reduced, the physicochemical properties of the fermentation products are optimized, and in addition, the low-temperature-resistant composting fermentation microbial inoculum has a certain deodorizing function.

Description

technical field [0001] The invention belongs to the field of composite microbial bacterial agents, and in particular relates to a low-temperature-resistant composting fermentation bacterial agent with deodorizing function and application thereof. Background technique [0002] my country produces a huge amount of agricultural organic waste. It is estimated that 3 billion tons of livestock and poultry manure and more than 700 million tons of crop straw are produced every year. These organic wastes are rich in nutrients needed for a large number of crop production. Through the method of aerobic composting, these organic wastes can be turned into high-quality organic fertilizers. The traditional composting method requires a certain amount of time to reproduce due to the small number of effective microorganisms in the initial stage. The fermentation time is long, the odor is large, and the loss of nutrients is large , serious waste of resources and other issues, especially in aut...

Problems solved by technology

Through the method of aerobic composting, these organic wastes can be turned into high-quality organic fertilizers. The traditional composting method requires a certain amount of time to reproduce due to the small number of effective microorganisms in the initial stage. The fermentation time is long, the odor is large, and the loss of nutrients is large , serious waste of resources and other issues, especially in autumn and winter in the north, due to the low ambient temperature outside, the problem of difficulty in starting the temperature of compost fermentation is particularly prominent

[0003] In addition, the composting process is often accompanied by the generation of foul-smelling gases, causing loss of appetite, dizziness, nausea, and vomiting, which has become an important restrictive factor affecting the development of the composting industry

The main components of malodorous gases include sulfides, ammonia, lower aliphatic amines, aromatic hydrocarbons, hydroxyl compounds, alcohols, lower fatty acids and indole, etc. Among them, ammonia and hydrogen sulfide are the main components of malodorous gases. The volatilization of these gases will pollute It damages the environment and loses nitrogen, which reduces the fertilizer efficiency of compost products
