| titleOfInvention | Material for filtering leaching solution in phosphogypsum slag yard |
| abstract | The invention discloses a material for filtering leaching liquor in a phosphogypsum slag yard, which is prepared by soaking and drying a porous adsorption material by a hydrophobic modifier at the temperature of 30-50 ℃ in an equal volume manner, then soaking and drying by a hydrophilic modifier at the temperature of 30-50 ℃ in an equal volume manner, and finally soaking and drying by a salt solution at the temperature of 50-80 ℃ in an equal volume manner; the material can be prepared into a filter assembly of a platy filter block formed by the screen meshes at two sides and the modified porous adsorption material layer in the middle, the filter assembly is used for treating the leaching solution of the phosphogypsum slag field, heavy metal and anion components in the leaching solution can be well adsorbed, the concentrations of substances such as the heavy metal, toxic and harmful anions and the like in the leaching solution are reduced, the adsorption time is long, the adsorption capacity is large, the cost is low, the preparation process is simple and the industrial application is easy, the treated phosphogypsum leaching solution meets the 3-class water body standard specified in the underground water quality standard, and the adsorbed heavy metal and anion components can be resolved to be used as secondary resources. |
