A method and apparatus for the treatment of waste liquids, in particular of industrial wastewater with a high solids content

摘要

method for treatment of waste liquid and, in particular, of industrial waste water with a high solids content.characterized by the following steps of: $(a) the liquid, together with a dry gas, in particular dry air in a spru00fchturm in counter current from dry gasin particular, dry airsprayed and evaporated; $a (b) solid particles of the waste water in the lower part of the spru00fchturms are collected; $a (c) the wet gas from the upper part of the spru00fchturms deducted in wu00e4rmeausexchange with the evaporator of a refrigerating unit,the evaporator and the condensed liquid is collected; $a (d) of the cooled dry gas is then in heat exchange with the condenser of refrigerating unit and heats and $a (e)dry gas is heated in a closed circuit to the steps of a) variability.
