Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of environmental protection equipment, in particular to a vertical unpowered induced-air aerobic quick composting device for organic garbage treatment.
[ background of the invention ]
Aerobic composting treatment of various perishable organic wastes (including common household wastes, kitchen wastes, garden wastes and the like) and mixtures thereof is a microbiological process for controllably promoting conversion of degradable organic matters in the wastes into stable humus by utilizing microorganisms such as bacteria, actinomycetes, fungi and the like widely distributed in the nature. The composted (fermented) products are referred to as compost. According to the different requirements of microorganisms on oxygen in the composting process of perishable organic matters, the composting process can be divided into aerobic and anaerobic processes.
The method can be divided into dynamic composting and static composting according to the state of the composting materials in the reaction system. The static composting process is divided into one-time composting and two-time composting. The one-time composting means that materials are piled up at one position to complete the whole biodegradation process, and the time is at least one month; the two-time composting is that the materials complete two stages of main fermentation/primary fermentation (harmless) and secondary fermentation (decomposition) at different positions, wherein the time of the harmless (high-temperature degradation) stage is generally 7-10 days, the further decomposition lasts for more than 10 days, and the time of the two stages cannot be less than 20 days. One of the main problems of the traditional static composting is that the poor ventilation and nutrient supply conditions lead to a series of problems of unbalanced and slow biodegradation. The basic measure for improving the ventilation conditions is forced ventilation, which in turn leads to increased energy consumption, i.e. increased treatment costs.
To solve the static compost aeration problem, patent CN201320379630.5 uses a ventilation pipe and an induced draft pipe to force induced draft into the compost windrow. But the induced air needs external power equipment such as an induced draft fan and the like. Patent cn201120166436.x "uses the hydrodynamics principle of citation to realize the self-induced draught of device, need not the auxiliary induced draught of power equipment. However, the air inducing effect is limited, and the air inducing amount is insufficient.
