Abstract
The invention discloses an acidiferous quartz mortar treatment method. The method comprises, A, filtering acidic waste water to remove suspended solids, adding active carbon into the acidic waste water, and carrying out stirring to remove colored impurities and tar so that primarily treated acidic water is obtained, and B, purifying and recovering the quartz sand waste pickling solution by a resin exchange method, wherein acid ions are blocked by a filler and metal ions go through the filler layer so that the acid is separated from the metal, washing to remove acid radicals of the filler by the equal amount of water so that recovered acid with a concentration basically same to a waste acid concentration is obtained, and can be used for recycling pickling solution preparation. The acidiferous quartz mortar treatment method has an acid recovery rate of 85-90%, realizes purification and recovery of hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, hydrofluoric acid and mixed acid and realizes zero discharge of waste water.
