Abstract
The present application is related to a method for controlling heavy metal scouring pollution in mines by using a humified product, which comprises steps of: (1) carrying out mixed fermentation on sludge and hyperthermophiles to breed polar humified groups, and then carrying out mixed fermentation on the fermented material and a native material of humus precursors to induce massive production of humus until the humus content reaches a required standard; and (2) mixing and maintaining the humified product of the sludge reaching the standard with mine soil polluted by heavy metals to remedy the polluted mine.
