ABSTRACT:
A method of cleaning phenol-containing waste waters as derived from coke-producing, chemical and other industrial processes comprises treating the waste water, generally without any preconcentration of the phenol content thereof or other prior treatment, with a one-use adsorbent, namely, brown-coal coke. The brown-coal coke is then subjected at least in part to a thermal treatment which can be a coke-producing process or combustion.
