Description

Technical Field

[0001] The utility model relates to a silo type aerobic fermentation machine. Background Art

[0002] At present, the mainstream methods of sludge treatment and disposal at home and abroad are landfill, drying incineration and land use. Anaerobic digestion technology and aerobic fermentation technology are mainly used in the treatment process. Aerobic fermentation technology of sludge is a new biological treatment technology that uses microorganisms in sludge for fermentation. That is, a certain proportion of bulking agents and conditioners are added to the sludge, and microbial communities are used to oxidize and decompose various organic matter in a humid environment and convert them into humus-like substances with higher stability. In practical applications, the effects of "stabilization, harmlessness, reduction, and resource utilization" can be achieved, and it has the characteristics of being economical, practical, requiring no external energy, and not generating secondary pollution. Aerobic fermentation technology is a practical technology suitable for sludge treatment and disposal.

[0003] The existing sludge aerobic fermentation system mixes organic matter (sludge), water and bacteria (microorganisms) in a fermentation bin, and introduces oxygen from the bottom of the fermentation bin. The bacteria need to be in an oxygen environment to oxidize the organic matter. Therefore, the sludge stacking height cannot be too high. When the height is too high, the lower part of the pile will be compacted due to the weight of the sludge, and normal ventilation cannot be carried out. A good oxygen environment cannot be provided for the bacteria, and aerobic fermentation cannot be sustained, affecting the fermentation effect.

[0004] The conventional aeration device of the fermentation system includes an aeration rack, a vibration mechanism, a feeding mechanism, etc., but its structure is too complicated and the production cost is high. Utility Model Content
