<P>PROBLEM TO BE SOLVED: To provide a treatment method for industrial drainage and a treatment apparatus for the industrial drainage, which treat surely a target component to be treated while suppressing the amount of use of a treatment chemical to a necessity minimum and can treat industrial drainage economically. <P>SOLUTION: Drainage treatment is carried out using the treatment apparatus. The treatment apparatus includes a concentration measuring apparatus 12 for a target component to be treated measuring the concentration of the target component to be treated in the industrial drainage, a concentration data obtaining means for a coexisting component influencing measurement results of the concentration of the target component to be treated, a data obtaining means 11 for the flow rate and drainage time of the industrial drainage, a treatment chemical adding means for adding the treatment chemical to the industrial drainage, an arithmetic device 20 for correcting the measured concentration of the target component to be treated based on the concentration of the coexisting component, and calculating the addition amount of the treatment chemical based on the corrected concentration, and the flow rate and the drainage time of the industrial drainage, and a control apparatus 30 adding the treatment chemical of the calculated addition amount by receiving the signal from the arithmetic device 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
