Description
Изобретение относитс к способу очистки сточных вод нроизводства синтетического каучука от диметилформамида.The invention relates to a method for the purification of wastewater from the production of synthetic rubber from dimethylformamide.
Известный способ очистки сточных вод от диметилформамида заключаетс в биохимическом окислении последнего с применением активного ила.A known method of treating wastewater from dimethylformamide consists in biochemical oxidation of the latter using activated sludge.
Однако при таком способе наблюдаетс низка степень очистки от диметилформамида , который окисл етс всего на 6,5о/о.However, with this method, there is a low degree of purification from dimethylformamide, which is oxidized by only 6.5 ° / o.
Предлагаемый способ отличаетс от известного тем, что в состав активного ила ввод т культуру микроорганизмов, выделенных из активного ила очистных сооружений нефтеперерабатывающей промышленности.The proposed method differs from the known one in that a culture of microorganisms isolated from the active sludge of the refining industry is incorporated into the activated sludge.
Это способствует повышению степени очистки до 85о/о.This helps to increase the degree of purification to 85o / o.
Пример. Применение селективных культур микроорганизмов дл окислени диметилформамида обеспечивает полную минерализацию последнего.Example. The use of selective cultures of microorganisms for the oxidation of dimethylformamide ensures complete mineralization of the latter.
Выделение н культивирование микроорганизмов (штаммов) производ т следующим образом.Isolation and cultivation of microorganisms (strains) are carried out as follows.
В 1000 мл водопроводной воды внос т следующие вещества, мг:The following substances, mg, are added to 1000 ml of tap water:
KHaPOi500KHaPOi500
Диметил форм амид100Dimethyl forms amide100
MnSO следыMnSO traces
FeClsследыFeCls traces
рН среды устанавливают в пределах 7,3-7,8. Затем в полученный раствор внос т 100 мл свежего активного ила с очистных сооружений нефтеперерабатывающего завода или 100 г почвы, на которую посто нно попадают нефтепродукты (применение других образцов почвы не дает положительного результата ).pH is set in the range of 7.3-7.8. Then, 100 ml of fresh activated sludge from the treatment facilities of the refinery or 100 g of soil, onto which oil products constantly fall, are added to the resulting solution (the use of other soil samples does not give a positive result).
Среду инкубируют в течение мес ца при 20-25°С. По истечении этого времени делают пересев в жидкую питательную среду, имеющую тот же состав, что и описанна среда, но без активного ила или почвы. Среду инкубируют при 20°С в течение двух недель и затем, когда она помутнеет, из нее делают посев на твердую питательную среду, следующего состава, Л1г:The medium is incubated for 20–25 ° C for a month. After this time, they do reseeding in a liquid nutrient medium having the same composition as the described medium, but without active sludge or soil. The medium is incubated at 20 ° C for two weeks and then, when it becomes cloudy, it is sown on solid nutrient medium of the following composition, L1g:
