Abstract

Disclosed is a method for biologically treating acidic mine wastewater while recovering iron ions. The method includes: (1) subjecting acidic mine wastewater to biomineralization by means of acidophilic iron-oxidizing bacteria, then subjecting same to a circulating biological reduction treatment by means of acidophilic iron-reducing bacteria, and then entering same into an alkali adjustment tank (8) for circulation adjustment of the pH, then discharging water and circulating same to a biomineralization unit (1) for a circulating treatment; and (2) after the reaction is carried out for a period of time, bringing the wastewater out from the end of an advection cistern (5), which subsequently can be connected with a lime neutralization treatment system, wherein in the biomineralization unit (1), a jarosite mineral or schwertmannite can be recovered. Also disclosed is a system for biologically treating acidic mine wastewater while recovering iron ions.
