Background
Composting refers to a biochemical process that utilizes microorganisms widely existing in nature to controllably promote the conversion of degradable organics in solid waste into stable humus. The compost is a process for producing the organic fertilizer, contains rich nutrient substances, has long and stable fertilizer efficiency, is favorable for promoting the formation of a soil granule fixing structure, can increase the water-retaining, heat-preserving, ventilation and fertilizer-retaining capacity of soil, and can make up the defects that the nutrient contained in the fertilizer is single, the soil is hardened and the water-retaining and fertilizer-retaining performances are reduced by singly using the fertilizer for a long time after being mixed with the fertilizer. The method can be divided into aerobic composting and anaerobic composting according to the biological fermentation mode. Aerobic composting is the process of absorbing, oxidizing and decomposing waste by aerobic bacteria under the condition of good ventilation condition and sufficient oxygen. The aerobic microorganism oxidizes a part of absorbed organic matters into simple inorganic matters through the life activities of the aerobic microorganism, simultaneously releases energy required by the growth activities of the microorganism, and synthesizes a new cytoplasm by the other part of organic matters, so that the microorganism continuously grows and breeds to generate more organisms. In general, aerobic composting is high in composting temperature, preferably at 55-60 ℃, so that aerobic composting is also called high-temperature composting. The high-temperature composting can kill pathogenic bacteria to the maximum extent, and meanwhile, the degradation speed of organic matters is high, the number of days required for composting is short, the odor occurrence amount is small, and the method is the first choice for composting.
