    摘要: A system for treating a selenium-containing liquid includes a concentration measurement element 15 for measuring the concentration of peroxodisulfuric acid and the concentration of tetravalent selenium in the selenium-containing liquid; a setting element 21 for setting the feed amount of bivalent manganese based on the concentrations of peroxodisulfuric acid and tetravalent selenium, and a reaction rate constant ratio which is the ratio of a reaction rate constant in a reaction between bivalent manganese and peroxodisulfuric acid to a reaction rate constant in a reaction between tetravalent selenium and peroxodisulfuric acid; and an addition element 14 for adding bivalent manganese to the selenium-containing liquid such that the bivalent manganese in the selenium-containing liquid is maintained in the above feed amount. Bivalent manganese is added to the selenium-containing liquid by the addition element, whereby oxidation of tetravalent selenium to hexavalent selenium is suppressed.
