In order to treat wastewater from uranium metallurgy, the chemical neutralization with slaked lime was experimented. The results illustrated that the effects of removal of uranium and thorium are obvious and can meet radioactive wastewater discharged standard, as well as other heavy metal ion and nonmetal ion, such as Mn, Fe, Pb, As, F can meet surface wastewater discharged standard. Moreover, the primary elements species and saturation indices of minerals in acidic solution can be calculated by geochemistry model PHREEQC, which indicated that the rock-water interaction mechanism between various minerals and water environment during treatment operation.
