The concentration of the reducing agent in the waste water in a residence tank after hexavalent chromium reduction treatment is quantitatively determined to determine whether or not the reducing agent concentration is a proper value. When the reducing agent concentration is not a proper value, the correction amount of the reducing agent added to the reduction tank is determined and a correction signal is output. When the correction signal is output, the reducing agent in an amount corresponding to the correction amount determined based on the correction signal is added to the reduction tank.  <P>COPYRIGHT: (C)2008,JPO&INPIT
