SYSTEM FOR TREATING SELENIUM-CONTAINING LIQUID, WET FLUE GAS DESULFURIZATION DEVICE, AND METHOD FOR TREATING SELENIUM-CONTAINING LIQUID |
摘要 |
A system for treating a selenium-containing liquid, a wet flue gas desulfurization device, and a method for treating a selenium-containing liquid treat a selenium-containing liquid by adding bivalent manganese to the selenium-containing liquid, thereby suppressing oxidation of tetravalent selenium to hexavalent selenium. The system includes: a potential measurement unit for measuring an oxidation-reduction potential of the selenium-containing liquid, and a pH measurement unit for measuring a pH value of the selenium-containing liquid; a detection unit for detecting whether or not the selenium-containing liquid is in a state where selenium stabilizes at a valence of 4 or higher, based on the measured oxidation-reduction potential and the measured pH value; and an addition unit for adding bivalent manganese into the selenium-containing liquid when the selenium-containing liquid is in a state where selenium stabilizes at a valence of 4 or higher.
