Abstract
PURPOSE: Fluorine-containing waste liquid is adjusted in pH so that basic calcium salt is added without fail, thereby to perform ensured deflurination, together with chromic acid containing waste treatment and to eliminate special expensive pretreatment equipment.
CONSTITUTION: For defluorination treatment, both chromic acid and fluorine containing waste liquids are mixed and neutralizied by adjusting pH so that neutralization is made possible by adding basic calcium salt solution. For example, pickling waste solution is charged from the tank 3 by pump 16 to the waste liquid cleaning tank 2 which is provided at liquid discharge route with a pump controller 15 with contact-point pH meter. The controller 15 continuously measures pH of liquid of loquid from the tank 2. If pH is higher than a specified value, the pH of the liquid charge from the tank 2 is controlled by the tank 16.
