| description | The invention discloses a method for reducing the biological activity of heavy metal in sludge composting with microorganisms. The method includes the steps that sludge is air dried ready for use; bacillus benzoevorans fungicide and fermentation auxiliary materials are added into the sludge, and are mixed evenly; the sludge after being mixed evenly is put into a fermentation tank, an outer layer of the fermentation tank is provided with an interlayer, the interlayer is communicated with a temperature control system, and the bottom of the fermentation tank is communicated with a blast aerationsystem; the temperature control system and the a blast aeration system are started and used for aerobic fermentation. According to the method for reducing the biological activity of the heavy metal inthe sludge composting with the microorganisms, bacillus benzoevorans is added into the sludge for aerobic fermentation, and the biological effectiveness of the heavy metal in the sludge composting can be generally reduced.
