Description
МЕТОД УТИЛИЗАЦИИ НЕФТЕСОДЕРЖАЩИХ ВОД METHOD FOR DISPOSAL OF OIL-CONTAINING WATERS
Изобретение относится к экологии, а именно к комбинированным методам утилизации нефтесодержащих вод и заключается в линейно-комплексной интеграции способов и технических средств для обработки нефтесодержащих вод и может быть использовано в судостроении, машиностроении, нефтехимической и нефтеперерабатывающей промышленности, а также в строительстве, на транспорте, энергетике и других отраслях промышленности, где происходит образование промывных, ливневых и технологических загрязненных вод, содержащих нефтепродукты наряду с другими растворенными и механическими примесями с целью снижения негативного воздействия на окружающую среду. The invention relates to ecology, namely to combined methods for the utilization of oily waters and consists in a linear-integrated integration of methods and technical means for the treatment of oily waters and can be used in shipbuilding, engineering, petrochemical and oil refining industries, as well as in construction, transport, energy and other industries where the formation of flushing, storm and technological polluted waters containing oil products, along with other dissolved and mechanical impurities in order to reduce the negative impact on the environment.
В настоящее время разработано большое количество технологических схем, обеспечивающих достаточно эффективную очистку вод от нефтепродуктов. Currently, a large number of technological schemes have been developed that provide a fairly effective treatment of water from oil products.
(RU 2359919, RU2344999, RU2092448). (RU 2359919, RU2344999, RU2092448).
Ужесточение требований по защите окружающей среды привело к созданию более совершенных способов очистки и к созданию многоступенчатых очистительных схем (RU 24193, RU2156740, RU1 13263, RU141342). The toughening of environmental protection requirements has led to the creation of more advanced cleaning methods and to the creation of multi-stage cleaning schemes (RU 24193, RU2156740, RU1 13263, RU141342).
Известны способы обработки водных сред, содержащих органические примеси с применением УФО (naT.RU 2142915,.1999, RU113263, 2010). Known methods of treating aqueous media containing organic impurities using ultraviolet radiation (naT.RU 2142915, .1999, RU113263, 2010).
Известные способы обработки нефтесодержащих сточных вод направлены на очищение их от нефтепродуктов. Known methods for the treatment of oily wastewater are aimed at purifying them from oil products.
Аналогов комплексно использующих для утилизации нефтесодержащих вод рекуперацию с фотохимической деструкцией и опреснением, для достижения обезвреживания, не выявлено. No analogues have been comprehensively used for the utilization of oily waters for recovery with photochemical destruction and desalination, in order to achieve neutralization, have not been identified.
Задачей изобретения является разработка метода утилизации нефтесодержащих вод с целью снижения негативного воздействия на окружающую среду и рационального использования природных водных ресурсов. The objective of the invention is to develop a method for the utilization of oily water in order to reduce the negative impact on the environment and the rational use of natural water resources.
Технический результат заключается в обезвреживании нефтесодержащих вод. The technical result consists in the neutralization of oily waters.
Технический результат достигается тем, что метод утилизации нефтесодержащих вод, как способ повышения экологической безопасности, включает линейно-комплексную обработку посредством рекуперации, фотохимической деструкции и опреснения, при этом рекуперацию выполняют в высокоскоростном сепараторе гравитационного типа под вакуумом и фильтрующем блоке с полимерными материалами, фотохимическую деструкцию - в реакторе с воздействием ультрафиолетового облучения.
Особенностью метода является то, что в отличие от большинства существующих систем утилизации нефтесодержащих вод, предлагаемое техническое решение позволяет провести обезвреживание и даёт возможность эксплуатировать промышленные и транспортные объекты не только в режиме «нулевого сброса», но и с наиболее рациональным использованием природных водных ресурсов и характеризуется тем, что впервые для утилизации нефтесодержащих вод комплексно используется рекуперация с фотохимической деструкцией и опреснением. The technical result is achieved by the fact that the method of utilization of oily water, as a way to improve environmental safety, includes linear-integrated processing by means of recovery, photochemical destruction and desalination, while the recovery is performed in a high-speed gravity-type separator under vacuum and a filter unit with polymeric materials, photochemical destruction - in a reactor with exposure to ultraviolet radiation. A feature of the method is that, unlike most existing systems for the utilization of oily waters, the proposed technical solution allows for neutralization and makes it possible to operate industrial and transport facilities not only in the “zero discharge” mode, but also with the most rational use of natural water resources and is characterized by the fact that for the first time for the utilization of oily waters, recovery with photochemical destruction and desalination is comprehensively used.
Данное техническое решение особенно актуально при современном уровне антропогенного воздействия на окружающую среду. This technical solution is especially relevant at the current level of anthropogenic impact on the environment.
Фиг. показана схематично система для осуществления метода утилизации нефтесодержащих вод, которая состоит из двух узлов обработки: FIG. schematically shows a system for implementing the method of disposal of oily water, which consists of two processing units:
- I узел, содержащий высокоскоростной центробежный сепаратор 1 и фильтроблок 2, снабжённый полимерными материалами, - I node containing a high-speed centrifugal separator 1 and filter unit 2, equipped with polymeric materials,
- II узел, содержащий реактор фотохимической деструкции УФО 3 с блоком опреснения 4. - II node containing a photochemical destruction reactor UFO 3 with desalination unit 4.
Метод утилизации нефтесодержащих вод осуществляется следующим образом. Нефтесодержащие воды подают в узел I, для удаления грубодисперсных примесей и нефтепродуктов методом гравитации в высокоскоростном сепараторе, в котором отделение частиц нефти происходит за счет разности плотности воды и нефтепродукта. Для повышения качества обработки и исключения диспергирующего воздействия подающего насоса, на частицы нефтепродукта, предусмотрена работа сепаратора под вакуумом, с установкой подающего насоса после сепаратора. Утилизация эмульгированных и частично растворённых нефтепродуктов происходит посредством обработанных различными способами полимерных материалов фильтроблока. Воздействовать на кинетику фазовых переходов взаимодействия нефтепродуктов и полимерных материалов можно химическими веществами (поверхностно-активЦыми веществами - ПАВ, присадками и т.д.). В фотохимическом реакторе узла II под действием ультрафиолетового облучения происходит фотохимическая деструкция органических соединений, т . в результате такого вмешательства изменяется радиус ядра и толщина адсорбционно-сольватной оболочки сложной структурной единицы, которая является элементом нефтяной дисперсной системы. С целью наиболее рационального использования водных ресурсов и утилизации нефтесодержащих вод в узле II осуществляется опреснение с применением различных способов (дистилляции, обратно-осмотического, частотно- резонансного).
Для испытания заявленного метода использовались нефтесодержащие воды с объектов водного транспорта Амурского пароходства. The method of disposal of oily water is as follows. Oil-containing water is supplied to node I, to remove coarse impurities and oil products by gravity in a high-speed separator, in which the separation of oil particles occurs due to the difference in the density of water and oil product. To improve the quality of processing and eliminate the dispersing effect of the feed pump on the oil particles, the separator is designed to operate under vacuum, with the installation of the feed pump after the separator. Utilization of emulsified and partially dissolved petroleum products occurs through the filter block polymer materials processed in various ways. It is possible to influence the kinetics of phase transitions of the interaction of petroleum products and polymeric materials with chemicals (surfactants - surfactants, additives, etc.). In the photochemical reactor of unit II, under the action of ultraviolet radiation, photochemical destruction of organic compounds occurs, i.e. as a result of this intervention, the radius of the core and the thickness of the adsorption-solvation shell of a complex structural unit, which is an element of the oil disperse system, change. With the aim of the most rational use of water resources and the disposal of oily water in node II, desalination is carried out using various methods (distillation, reverse osmosis, frequency resonance). To test the claimed method, oil-containing waters from the water transport facilities of the Amur Shipping Company were used.
Результаты промежуточной стадии опытной проверки заявляемого метода утилизации нефтесодержащих вод представлены в таблице. The results of the intermediate stage of the pilot verification of the proposed method for the disposal of oily waters are presented in the table.
Данные химико-аналитического контроля. таблица Data of chemical analytical control. table
Плавающие примеси и пленка в пробах не обнаружены. No floating impurities and film were detected in the samples.
Анализ полученных результатов лабораторного исследования подтверждает достижение обезвреживания нефтесодержащих вод применением заявленного метода, т.к. происходит значительное снижение массы вредных веществ уже на промежуточной стадии обработки. An analysis of the results of a laboratory study confirms the achievement of the neutralization of oily water using the claimed method, because a significant reduction in the mass of harmful substances occurs already at an intermediate stage of processing.
Результаты опытной обработки нефтесодержащих вод подтвердили возможность наиболее рационального использования водных ресурсов даже в областях требующих наличия особо чистых пресных вод, например для использования в качестве добавочной котловой воды при производстве пара как в промышленности так и на транспорте (водный транспорт).
The results of the pilot treatment of oily water confirmed the possibility of the most rational use of water resources even in areas requiring the availability of highly pure fresh water, for example, for use as auxiliary boiler water in the production of steam both in industry and in transport (water transport).
