RESTORATION METHODS OF CONTAMINATED SOIL BY HEAVY METAL USING ORGANIC WASTE

摘要

A method for restoring soil contaminated in a heavy metal by using organic waste is provided to activate microorganisms by improving environment such as the soil polluted in the heavy metal, the soil of a closed mine area, etc by recycling the organic waste thrown away to waste. A method for restoring soil contaminated in a heavy metal by using organic waste comprises the following steps of: separating solid materials form the organic waste; producing fermentation liquor by fermenting the organic waste in which the solid material is separated; and injecting fermentation liquid in the soil. A mixing method includes the following steps of: installing a screw(11) on an outer circumference of a rod; installing a pipe to inject the fermentation liquid into the rod; and injecting the fermentation liquid through a nozzle with the air.
