Abstract | FIELD: process engineering.SUBSTANCE: invention relates to biotechnology and may be used for wasteless cleaning of water and solid surfaces from oil and oil product outflow. Proposed material comprises outer layer of polyester fibers and mid layer of polypropylene fibers comprising incorporated phosphorus-containing cationites and/or nitrogen-containing anionites, cell walls of hydrophytes and immobilised cells of oil destruction bacteria. Proposed biohybrid material features sorption capacity of, at least, 25 g/g of sorbent and degree of bacteria cell load of, at least, 150 mg/mand may be used may times: at least, 5 regeneration cycles with extraction of, at least, 90% of sorbate in first cycle.EFFECT: wasteless cleaning of water and solid surfaces from oil and oil product outflow.2 ex
Изобретение относится к биотехнологии и может быть использовано при безотходной очистке от аварийных разливов нефти и нефтепродуктов водных и твердых поверхностей. Предложен биогибридный материал для сорбции и деградации нефти и нефтепродуктов поверхностных и донных отложений. Материал включает внешние слои из полиэфирных волокон и промежуточный слой из полипропиленовых волокон, которые содержат инкорпорированные фосфорсодержащие катиониты и/или азотсодержащие аниониты, клеточные стенки водных растений семейства Рясковые и иммобилизованные клетки бактерий-нефтедеструкторов. Биогибридный материал обладает сорбционной емкостью не менее 25 г/г сорбента и степенью бактериальной клеточной загрузки не менее 150 мг/мсорбента, может быть использован многократно: не менее 5 циклов регенерации с извлечением не менее 90% сорбата в первом цикле. 2 пр. |
