摘要： PROBLEM TO BE SOLVED: To provide a treating method for a selenium-containing solution which can reduce the amount of an added ferrous compound required for removing selenium in a solution like waste water generated after washing dust, and decrease the concentration of selenium in the treated solution to or below an effluent standard value (≤0.1 mg/l as a residual selenium concentration).
SOLUTION: The treating method comprises (A) a process where an acid is added to selenium-containing waste water in a pretreatment tank 2 to adjust its pH to 4 or below and in such a condition, the ferrous compound like ferrous chloride is added thereto to obtain a solution containing divalent iron ions, (B) a process where an alkali agent 16 like calcium hydroxide is added at an alkali agent supply opening 15 while making the solution obtained in the process (A) flow into a passage 3 and the pH of the solution on the downstream side is adjusted to 8-12 to obtain a solution containing a solid comprising metal selenium and ferrous hydroxide, and (C) a process where the solution obtained in the process (B) is subjected to solid-liquid separation by using a filter 5.

摘要： PROBLEM TO BE SOLVED: To provide a method for removing metal ions other than copper contained in a solution which mainly contains monovalent copper ions and is used in a process of recovering metal copper from the solution by an electrolytic operation. SOLUTION: In a process of recovering metal copper by dissolving the copper metal waste in the solution containing divalent copper ions, and by electrolyzing the obtained solution mainly containing the monovalent copper ions to make the metal copper deposited, this recovering method includes: adding phosphoric acid or a phosphate, which has a low solubility product with lead, into the solution containing the divalent copper ions, or into the solution mainly containing the monovalent copper ions after the dissolution treatment. Thereby, the method prevents lead from being dissolved into the solution and being mixed in copper to be recovered. COPYRIGHT: (C)2009,JPO&INPIT
