To provide a method for treating a polymer wax peeling waste liquid capable of abolishing industrial waste.
The polymer wax peeling waste liquid is treated by a flocculation treatment process for adding acid to the polymer wax peeling waste liquid to deposit a polymer mass, the separation extraction process for extracting the polymer mass to separate the peeling waste liquid into the polymer mass and primary treated water, the neutralization treatment process for adding alkali to the primary treated water, the dehydration treatment process for separating the primary treated water into a solid content and secondary treated water, and the biological treatment process for mixing the secondary treated water with activated sludge. As the activated sludge to be used in the biological treatment process, activated sludge acclimatized by carrying out culture in the secondary treated water is used.
