Способ относится к очистке сточных вод, содержащих нитроцеллюлозу (НЦ), и заключается в обработке обогащенной кислородом водной суспензии НЦ микроорганизмами родов Pseudomonas ,Bacillus в исходном количестве 103 oC 104 кл на 1 мг нитроцеллюлозы в пересчете на сухой остаток при перемешивании в течение 15 - 25 суток со скоростью 200 - 1000 об/мин, значениях pH 5,5 oC 7,2 и температуре - 30 - 36°С, при этом содержание растворенного кислорода должно составлять 1 oC 3 мг/л, а микроорганизмы используются с источниками, содержащими фосфор, калий и микроэлементы. Предлагаемый способ исключает выделение токсичных веществ.The method relates to the treatment of wastewater containing nitrocellulose (NTS), and consists in treating an oxygen-rich aqueous suspension of NTS with microorganisms of the genera Pseudomonas, Bacillus in the initial amount of 10 3 o C 10 4 C per 1 mg of nitrocellulose, calculated on the dry residue when mixed for 15 to 25 days at a speed of 200 to 1000 rpm, pH values of 5.5 o C 7.2 and a temperature of 30 to 36 ° C, while the content of dissolved oxygen should be 1 o C 3 mg / l, and microorganisms are used with sources containing phosphorus, potassium and trace elements. The proposed method eliminates the release of toxic substances.
