FIELD: chemistry.
SUBSTANCE: invention can be used for neutralisation of sewage water containing dissolved explosive substance, for instance, octogen. Method of sewage water purification lies in decomposition of explosive substance dissolved in it in presence of sulphuric acid under action of ultraviolet rays in bath by circulation according to scheme tank - peristaltic pump-nutsch filter - peristaltic pump - bath - tank. Distance between source of ultraviolet rays and surface of sewage water in bath does not exceed 11 cm, thickness of water layer in it does not exceed 3 cm, and total duration of irradiation is from 0.33 to 0.5 hour.
EFFECT: intensification of sewage water neutralization process.
