TREATMENT METHOD OF PROCESS LIQUID

PROBLEM TO BE SOLVED: To provide a treatment method of two or more kinds of process liquids which contains two or more kinds of active ingredients and uses water as a medium. SOLUTION: Treatment equipment which satisfies the following conditions of (A)-(G) is used. (A): The treatment equipment is like a container capable of holding liquid. (B): The treatment equipment has a recovery section and a waste water section, wherein the recovery section and the waste water section contact the bottom of the treatment equipment, are installed in the upper perpendicular direction, and an upper end is partitioned by a partition plate (I) located below the liquid surface. (C): Means for supplying liquid to be processed are provided in each of the recovery section and the waste water section. (D): A means for quantitatively extracting recovered liquid is provided at a lower part of the recovery section. (E): The waste water section has a water passage at a lower part, and has a partition plate (II) installed in the lower perpendicular direction from an upper part of the surface of the liquid. (F): The waste water section has an outlet which performs overflow discharge of the waste water from the upper part. (G): An upper end of the partition plate (I) is higher than a lower end of the partition plate (II). COPYRIGHT: (C)2011,JPO&INPIT
