| titleOfInvention | A kind of method of precipitate and separate arsenic from acid water |
| abstract | The invention discloses a kind of method of precipitate and separate arsenic from acid water, extract acid water and put into acid solution reactor, pyroantimonate is put into by liquid-solid ratio 4～10mL:1g, heating is to 45 DEG C～60 DEG C, after reacting 15 minutes～20 minutes, reactant liquor is taken out toward pressure filter filter pressing, dearsenization filtrate flows to reclaims acid and valuable metal operation, the pyroantimonate filtering residue of load arsenic puts into alkaline solution reactor by solid-to-liquid ratio 1g:3～8mL, pass into air, heating is to 78 DEG C～90 DEG C, reactant liquor is taken out toward pressure filter filter pressing by stirring reaction after 60 minutes～100 minutes, after filter pressing, rich arsenic filtrate flows to and produces arsenic trioxide arsenic product sequence, pyroantimonate filtering residue after dearsenization returns acid solution reactor.The invention has the beneficial effects as follows: selecting pyroantimonate as dearsenization medicament, dearsenization is effective, the pyroantimonate after dearsenization can reuse, processing cost is low, and hazardous solid waste produces few, non-secondary pollution. |
