Problems solved by technology

[0003] As more and more attention is paid to the classification and treatment of organic waste, organic waste treatment technology has developed rapidly. In this process, biological treatment methods based on anaerobic fermentation and aerobic fermentation have gradually formed, and anaerobic fermentation is generally used In large-scale centralized treatment projects with a treatment capacity of at least 100 tons / day, large-scale anaerobic projects have great limitations in some specific areas, such as schools with concentrated sources of domestic waste, canteens of government agencies, and islands with inconvenient transportation , mountainous areas, and rural areas, so there is a great demand for miniaturized organic waste treatment technology
[0004] my country's small-scale aerobic fermentation technology is imported from Japan. The bacteria used have been imported from Japan for a long time, and the frequency of dosing is high and the price is expensive, resulting in extremely high operating costs. Moreover, most of China's organic waste is mixed waste, mainly including kitchen waste, fruits and vegetables Garbage, garden and agricultural waste, etc., the bacterial agents imported from Japan are not well adapted locally, and the reduction rate of organic waste after fermentation is low and the water content is high

Embodiment approach

[0055] According to one embodiment of the present invention, the organic waste may be at least one of the above wastes.

[0056] According to the present invention, the aerobic fermentation can be batch fermentation or continuous fermentation. In order to improve the treatment efficiency more effectively, the method of the aerobic fermentation is continuous fermentation, that is, the materials of the aerobic fermentation are continuously drawn out and fresh organic waste is continuously introduced together with the microbial agent, microbacteria CGMCC NO.18967 or spores Bacillus CGMCC NO.18966 for contact.

[0057] According to the present invention, there is no special restriction on the inoculum amount of microbial bacterial agent, microbacteria CGMCC NO.18967 or bacillus CGMCCNO.18966 in organic waste, a kind of preferred inoculum amount among the present invention, with respect to the organic waste of every gram, The consumption of described microbial bacterial agent, mic...

Abstract

The invention relates to the field of biofermentation and discloses a microbial agent. The microbial agent contains a microbacterium, a bacillus, a lactobacillus, Acinetobacter and Pseudomonas. The invention further discloses the microbacterium. The microbacterium has an accession number of CGMCC NO. 18967. The microbial agent and the microbacterium CGMCC NO. 18967, provided by the invention, arehigh in adaptability and good in stability; and in aerobic fermentation equipment, the microbial agent and the microbacterium CGMCC NO. 18967, provided by the invention, are mixed with organic garbage, then, aerobic fermentation is carried out, the moisture content of an obtained fermentation product is lowered to 18wt%, and the decrement rate of the obtained fermentation product reaches up to 92wt%.

Description

[0001] Technical Field The present invention relates to the field of microbial fermentation, in particular to a microbial agent, microbacteria and their applications. Background technique [0002] With the development of the economy, the amount of domestic waste in my country has increased rapidly. In 2017, the volume of domestic waste removal has exceeded 200 million tons, and it has grown at a rate of 5-8% per year. Among them, organic waste accounts for 40-40% of the total domestic waste. 70%, so the classification of organic waste has become a top priority. [0003] As more and more attention is paid to the classification and treatment of organic waste, organic waste treatment technology has developed rapidly. In this process, biological treatment methods based on anaerobic fermentation and aerobic fermentation have gradually formed, and anaerobic fermentation is generally used In large-scale centralized treatment projects with a treatment capacity of at least 100 tons / day,...
