Process of composting fermentation

2018/10/10 13:34:12

The composting process is mainly carried out by the action of microorganisms, which are the main body of composting fermentation. There are two sources of microorganisms involved in composting: one is the large number of microorganisms in the organic waste; the other is the artificially added microbial inoculant. These strains have strong decomposition ability to certain organic wastes under certain conditions, and have the characteristics of strong activity, rapid reproduction, and rapid decomposition of organic matter, which can accelerate the progress of composting reaction and shorten the time of composting reaction.

Composting is generally divided into aerobic composting and anaerobic composting. Aerobic composting is the decomposition process of organic materials under aerobic conditions. Its metabolites are mainly carbon dioxide, water and heat. Anaerobic composting is the decomposition process of organic materials under anaerobic conditions. The final metabolite of anaerobic decomposition is methane. Carbon dioxide and many low molecular weight intermediates such as organic acids.

During the composting process, the microbial population changed with temperature as follows: the low- and medium-temperature microflora mainly changed to the middle-high temperature microflora, and the middle-high temperature microflora mainly converted into the middle-low temperature microflora. As the composting time prolonged, the bacteria gradually decreased, the actinomycetes gradually increased, and the molds and yeasts decreased significantly at the end of composting.
