发明名称 Method and apparatus for treating selenium-containing wastewater
摘要 A method and an apparatus for treating selenium-containing wastewater, in which wastewater containing hexavalent selenium is subjected to reduction treatment, selenium can be effectively removed at a small amount of metal leached, and, preferably, sludge produced during treatment is white, thereby facilitating the disposal of the sludge.
