The invention discloses a high-temperature aerobic
fermentation process for
sludge with low
energy consumption and no
pollution, and relates to the technology for aerobic
fermentation treatment on
dewatered sludge. The process is used for decontamination, stabilization and
reduction treatment of town
sewage sludge,
sewage sludge, organic industrial
wastewater sludge and organic sludge. In the process, the
dewatered sludge and auxiliary materials are mixed, the mixture is crushed into composting particles with the
diameter less than or equal to 20mm, the composting particles are evenly distributed into a
pile with the height of 2m by a spreader, and the
pile is covered by fermented decaying products to effectively reduce the
odor emitted by the composting. A
fermentation bin with two combined or separated bins is provided with a ventilation and
oxygen supply
system which is detachable, is easy to clear, prevents blockage and has even gas distribution, and a
pile turning device inside; and the
oxygen concentration, fermentation temperature, water ratio of the pile in the fermentation bin are controlled, so that sludge fermented products meet
national standard. The process facilitates air supply and aerobic fermentation of the pile due to small
diameter of the composting particles and the loose pile, has thorough fermentation of the particles of the sludge mixture, improves the quality of the sludge fermented products, makes the sludge fermented products meet the decontamination, stabilization and reduction index requirements specified by the
national standard, and greatly saves
electric energy consumption and reduces
operating cost.
