Abstract
1. СПОСОБ БИОХИМИЧЕСКОЙ ОЧИСТКИ СТОЧНЫХ ВОД ОТ ЦИАНИДОВ, включающий использование биокультуры , отличающийс тем, что, с целью возможности очистки от органических флотореагентов при одновременном повышении степени очистки от цианидов, в качестве биокультуры используют чайный гриб-, предварительно культивируемый на пастеризованной сахарной среде. 2. Способ по п. 1, отличающий с тем, что.используют чайный гриб, предварительно культивируемый 6-8 сут на пастеризованной сахарной среде с добавлением ча (Л при 22-25С.1. METHOD OF BIOCHEMICAL TREATMENT OF SEWAGE WATER FROM CYANIDES, including the use of bioculture, characterized in that, in order to be able to purify from organic flotation reagents while simultaneously increasing the degree of purification from cyanides, Kombucha, previously cultivated on pasteurized sugar medium, is used as bioculture. 2. The method according to p. 1, characterized in that. Kombucha, previously cultivated for 6-8 days on pasteurized sugar medium with the addition of tea (L at 22-25C.

1 ; Изобретение относитс к очистке про(4ытлеиных сточных вод предпри ти цветной металлургии от органических фцотореагентов и цианидов биохимическим Способом и может быть использовано на предпри ти х черной металлургии, химической промышленности и других предпри ти х дл очи ки вод аналогичного состава. Цель изобретени - возможность очистки сточных вод от органических флотореагентов при одновременном по вышении степени очистки от цианцдов . 87 Пример 1. Биомассу чайного гриба получают выращиванием его мицелли на пастеризованной сахарной среде, содержащей до 7% сахарозы и 0,1% ча при 22-25с. В 1 л исходного раствора, содержащего 100 мг/л органического флотореагента - керосина, и 17,5 мг/л цианидов, внос т чайньй гриб в количестве 3-5 об.%. Полученный раствор термостатируют в течение 48 ч при 22-25 С. Сравнительные данные известного и предлагаемого способов приведены в таблице.one ; The invention relates to the treatment of prod- ucts (4-waste sewage of enterprises of non-ferrous metallurgy from organic photoreagents and cyanides by the biochemical method and can be used in enterprises of ferrous metallurgy, chemical industry and other enterprises for purifying water of similar composition. Purpose of the invention is the possibility of cleaning wastewater from organic flotation reagents while simultaneously increasing the degree of purification from cyanthium 87 Example 1. Kombucha biomass is obtained by growing its micelles on pasteurized sugar a medium containing up to 7% sucrose and 0.1% tea at 22–25 s. In 1 liter of the initial solution containing 100 mg / l of organic flotation reagent — kerosene, and 17.5 mg / l of cyanide, 3-5 vol.%. The resulting solution is thermostatic for 48 hours at 22-25 C. Comparative data of the known and proposed methods are given in the table.
