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.

Method of cleaning phenol-containing waste waters

The zinc-containing dust from an iron-making (blast) furnace or a steel-refining (e.g. converter) furnace is recovered and extracted with water saturated with carbon dioxide to solubilize the zinc. The zinc solubilized in the CO.sub.2 -saturated water is then precipitated by the elimination of carbon dioxide therefrom.
