FIELD: chemistry.
SUBSTANCE: method for processing the sewage sludge of nitrocellulose production includes a continuous loading of wet nitrocellulose sludge to the aqueous sodium or potassium hydroxide solution close to saturation, with the initial temperature of 10-95°C. The solution is continuously stirred with the intensity sufficient for the precipitate particles to be in suspended state and to be evenly distributed in the liquid volume. The feed rate of sludge into the alkaline suspension is maintained such that the mass fraction of precipitate particles in the suspension does not exceed 5%.
EFFECT: reducing the energy consumption for nitrocellulose sludge processing, reducing the processing time and simplifying the processing process hardware design.
