摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for stably and efficiently treating selenium-containing water containing ions of a metal which is nobler than titanium as a coexisting substance wherein the selenium-containing water is subjected to reduction treatment by contacting the selenium-containing water with a mixture of metallic titanium and a simple metal baser than titanium, while preventing a decrease of selenium-treating performance with time.SOLUTION: A pretreatment of removing ions of the metal nobler than titanium from selenium-containing water is performed prior to reduction treatment of selenium with the mixture of metallic titanium and the simple metal baser than titanium. In a reduction treatment step of selenium, noble metal ions in the selenium-containing water are reduced on the surfaces of particles of metallic titanium in a titanium/base metal mixture to form precipitates, which adhere to the surfaces of the metallic titanium particles, resulting in the decrease in efficiency of a reduction reaction. This problem can be solved in such a manner that the noble metal ions are removed prior to the reduction treatment of selenium.
