| titleOfInvention | Method for treating wastewater containing selenate |
| abstract | The invention discloses a method for treating wastewater containing selenate, which comprises the following steps of firstly adjusting the pH value of the wastewater containing selenate to be more than 7; then adding an adsorbent into the selenate-containing wastewater according to a solid-liquid ratio of 1.5-2.5 g/L, and stirring for 10-15 hours; finally, removing the adsorbent to finish the treatment of the wastewater containing the selenate; the adsorbent is Y 2 (OH) 5 Cl·1.5H 2 And O. The rare earth element-based adsorbent Y of the present invention 2 (OH) 5 Cl·1.5H 2 O, the adsorbent material is a two-dimensional layered material, the laminates are positively charged, free chloride ions are contained among the laminates, selenate can be effectively removed, the removal rate of selenate in selenate wastewater is up to 99.9%, and particularly, the adsorbent material has a good circulation application effect. |
