- Аннотация: The development of methods and techniques aimed at accelerating the decomposition of sewage from the production of nitrated cellulose (NC) at treatment facilities of industrial enterprises will allow to solve environmental problems associated with the accumulation of large amounts of fire and explosive dangerous material in pond-settling ponds and thereby reduce the negative load on the environment.The NC with 13.38 % nitrogen content was studied. Biological oxidation was carried out with the bacteria Desulfovibrio desulfuricans [1] and fungi Fusarium solani [2]. We considered the change in the state of NC in a joint incubation on bacteria and fungi, in the community of microorganisms of active silt, and also in a variant of preliminary treatment of NC with the help of hard ultraviolet irradiation (UV) and ozone during 27 hours. Incubation of NC with microorganisms was carried out for 65 days. Several parameters were measured during this study: pH, nitrate and nitrite ion content, solution viscosity, H, S, C, N quantity and molecular weight distribution for the isolated and dried sample.
