<p><P>PROBLEM TO BE SOLVED: To provide a method for treating selenium-containing water, in which selenium can be easily removed from selenium-containing water at a high recovery rate and at a low cost and a selenium-containing compound can be efficiently separated/recovered from selenium-containing water. <P>SOLUTION: The method for treating selenium-containing water comprise the steps of: adding copper powder or a copper compound to the selenium-containing water to be produced at a smelting step to exude/reduce selenium by copper; adding metal powder such as Fe powder and Zn powder having the ionization tendency larger than that of copper to produce/recover a precipitate, namely, to remove selenium together with copper. The recovered precipitate is used as a raw material for a flash smelting furnace to recover selenium. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
