Abstract: The invention relates to a process for the treatment and purification of dangerous wastes containing ammonium salts, particularly ammonium chloride, derived from pharmaceutical and chemical technologies. The process includes the following steps: removing the organic solvent content of the waste mixture, containing an aqueous and non-aqueous phase, by phase separation based on the difference in the special weight and/or by azeotrop distillation, and heating the obtained aqueous solution at its boiling point or at a temperature belonging to the maximal saturation boiling point of the ammonium salt until the non-solvent type organic substances precipitate in the form of a well separable polymerisate phase, whereafter this phase is separated from the aqueous solution of the ammonium salt and the ammonium salt, preferably the ammonium chloride is purified by a method known per se.
