Municipal sludge energy-saving high-efficiency fast bio-drying technology

The invention discloses a municipal sludge energy-saving high-efficiency fast bio-drying technology. According to the invention, with a high-temperature strain and a corresponding ventilation structure, municipal sludge can be dried fast, a drying process can be accelerated, and energy can be saved. According to the invention, a 55 DEG C high-temperature stage is maintained for 20 days, and a 65 DEG C high-temperature stage is maintained for 13 days, such that harmful pathogens in sludge can be thoroughly killed. Also, when the method provided by the invention is combined with corresponding equipment, the scale of the drying process can be expanded.
