摘要

PURPOSE: phosphate surface coating agent and a kind of offer of inhibition acid wastewater in mine prevent acid water to be discharged, since the sample of oxidation of pyrite is eluted with various heavy metal ion including Fe in advance. ;CONSTITUTION: the mixing of phosphate surface coating agent obtains NaClO aqueous solutions, in H2O2 aqueous solutions, KH2PO4 aqueous solutions and NaOAc aqueous solutions. A kind of inhibition acid wastewater in mine following steps: step 1 is rapid, in punching injection hole, enters that mine which pyrite is embedded in for injecting surface application agent; Second step flows into spray-hole by injection induced oxidation surface application agent and surface coating agent is made to penetrate into pyrite rock. ;The 2012 of copyright KIPO submissions
