PURPOSE:To treat stably the waste water from film transfer and to improve the performance of the treatment by bringing the waste water from film transfer into contact with bentonite. CONSTITUTION:Waste water 2 discharged from a film transfer device is brought into contact with bentonite 8. Accordingly, org. materials in the waste water from film transfer are adsorbed by the bentonite, and, in this case, the org. materials in the particle diameter range which is occupied by the greatest part of the org. substance are absorbed in extremely large amts. Consequently, dependence on biological treatment, etc. is extremely alleviated, treatment of the waste water from film transfer is stabilized, and the performance of the waste water treatment can be improved. |
