Beschreibung
Zusammenfassung:	The invention deals with a method of disposal of wastewater containing a substance with an inorganic constituent on the basis of azides and/or substances with an organic constituent on the basis of an aromatic compound the benzene core of which contains as substituents nitro groups or amino groups. The disposal process consists in treatment of pH of wastewater to a value lower than 3, advantageously to a value lower than 1 and subsequent oxidation of the inorganic and/or organic constituent with a solution containing the permanganate ion. For the detection of the end of oxidation of the concerned constituents of wastewater potentiometric indication can be used. The invention can be used for disposal of wastewater from the production of explosives on the basis of lead azide, lead trinitroresorcinate, lead picraminate and the production of raw materials necessary for the synthesis of the above mentioned explosives.
