| titleOfInvention | Treatment method for wastewater containing Se and As |
| abstract | (57) [Problem] To provide a method for treating wastewater containing Se and As which can remove both Se and As at a high removal rate. SOLUTION: After ferrous salt is added to waste water containing Se, As or further Sn, Ca (OH) 2 and / or CaO 2 are added and reacted, and the obtained treated liquid is subjected to solid-liquid separation. , As-containing wastewater treatment method, and lead scrap and / or Alternatively, the lead slag and smoke obtained from the reduction smelting of roasted copper slime obtained in the electrolytic refining step of blister copper and / or the slag obtained by reduction smelting of the roasted copper de-slime slime (: Slag) as a raw material, and in a production process of electric tin using a smelting furnace and a tin removal pot as a subsequent step and a tin electrolytic tank as a subsequent step of the tin removal pot, a wastewater containing an electrolytic tail liquid of the tin electrolytic tank A method of treating wastewater containing Se and As, in which Ca (OH) 2 and / or CaO 2 is added and reacted after adding a ferrous salt to the resulting solution. |
