Abstract

The invention discloses a microbial agent for aerobic fermentation and rapid heating of organic solid waste in winter. The microbial agent is prepared from 50-70 parts of bacillus stearothermophilus, 50-70 parts of high-temperature-resistant pseudomonas, 50-70 parts of cellulomonas flavigena, 30-40 parts of bacillus subtilis, 30-40 parts of pseudomonas aeruginosa, 15-25 parts of ochrobactrum, 15-25 parts of clostridium, 15-25 parts of aspergillus niger, 5-15 parts of trichoderma viride, 5-15 parts of geotrichum candidum, 3-10 parts of white rot fungi, 3-10 parts of brown rot fungi, 1-5 parts of green algae and 1-5 parts of blue algae. A preparation method comprises the steps of (1), weighing of all the raw materials; (2), strain activation; (3), compounding of mixed strains; (4), preparation of a first-grade seed solution; and (5), preparation of the microbial agent. The microbial agent is novel in combination, high in viable count, high in synergistic effect and capable of achieving rapid heating and fermentation of organic solid waste piles.

Description

technical field [0001] The invention relates to the technical field of bacterial agents, and more specifically relates to a bacterial agent for rapid heating of organic solid waste in aerobic fermentation in winter and a preparation method thereof. Background technique [0002] Organic solid waste refers to solid organic objects and substances that have lost their original use value or have not lost their use value but have been discarded or abandoned during production activities, including agricultural organic waste (mainly including crop straw vines, livestock and poultry waste, etc.) Feces and aquatic waste, etc.), industrial organic waste (mainly including organic waste residues, etc.), municipal organic waste (mainly including landscaping waste, municipal sludge, animal inclusions from slaughterhouses, and kitchen waste, etc.). With the rapid development of my country's economy and the continuous improvement of people's living standards, organic solid waste presents the...
