Description
Изобретение относитс iK области очистки промышленных и сточных вод от фенола.This invention relates to the iK field of industrial and wastewater purification from phenol.
Известный способ очистки промышленных и сточных вод от органических :веш,еств, в том числе и от фенола, заключаетс в обработке очищаемой жидкости импульсными электрическими разр дами при электрофизическом режиме, соответствующем энергии единичного им пульса от 20 до 250 дж и длительности разр да до 10 мксек.A known method of purification of industrial and waste water from organic: substances, including phenol, consists in treating the liquid to be purified with pulsed electrical discharges in an electrophysical mode corresponding to the energy of a single pulse from 20 to 250 joules and a discharge duration of up to 10 mksek.
Однако этот способ имеет невысокую эффективность применительно к водным растворам фенолов.However, this method has low efficiency with respect to aqueous solutions of phenols.
Цель изобретени -повысить эффективность очистки, благодар применению специально разработанного электрофизического режима обработки импульсами высокого напр жени водных растворов фенолов различного строени с учетом особенностей среды и развити в ней потоков зар женных частиц. Предлагаемый способ отличаетс тем, что процесс осуш ,ествл етс с пробоем жидкости при энергии импульса 500-2000 дж, длительности разр да 10-100 мксек с выделением в предпробивном периоде от 50 до 80% запасенной энергии. The purpose of the invention is to increase the cleaning efficiency due to the use of a specially developed electrophysical mode of treatment with high voltage pulses of aqueous solutions of phenols of various structures, taking into account the peculiarities of the environment and the development of flows of charged particles in it. The proposed method is characterized in that the drying process is accomplished with the breakdown of a liquid with a pulse energy of 500-2000 J, a discharge duration of 10-100 microseconds, with a release of 50 to 80% of stored energy in the pre-breakdown period.
Эффективность очистки повышаетс приблизительно в четыре раза. Это видно из примера , который относитс к обработке водного раствора наиболее пассивного представител фенолов - оксибензола.The cleaning efficiency is about four times as high. This is evident from an example that relates to the treatment of an aqueous solution of the most passive phenol — oxybenzene.
Пример. Вли ние электрофизического режима на интенсивность и степень деградации оксибензола (при осуществлении процесса по известному способу).Example. The effect of the electrophysical regime on the intensity and degree of degradation of oxybenzene (when the process is carried out by a known method).
Опыт 1. Обработка водного раствора оксибензола с концентрацией 0,070 вес. % ведетс при доступе воздуха, напр жении 30 кв, разр дной емкости 0,6 мкф, межэлектродном рассто нии 20 мм, энергии, одного импульса 225 дж, длительности разр да менее 10 мксек.Experience 1. Treatment of an aqueous solution of hydroxybenzene with a concentration of 0.070 weight. % is maintained at the access of air, a voltage of 30 kV, a discharge capacitance of 0.6 microfarads, an interelectrode distance of 20 mm, energy, a single pulse of 225 j, and a discharge duration of less than 10 microseconds.
Результаты обработки 200 импульсами в расчете на объем пробы 1000 мл: степень разложени оксибензола 6,2%, энергетический выход разложени (убыль органического вещества ): начальный 0,07 молекулы/100 эв, в последующем-со снижением примерно вдвое.The results of treatment with 200 pulses per 1000 ml sample volume: the degree of decomposition of oxybenzene is 6.2%, the energy yield of decomposition (loss of organic matter): the initial 0.07 molecule / 100 eV, followed by a decrease by about half.
Опыт 2. Процесс осуществлен по предлагаемому способу. Берут тот же раствор, что и в первом опыте, при напр жении 40 кв, разр дной емкости 1,2 мкф энергии импульса 530 дж, длительности разр да 35 мксек; прочие услови ведени опыта практически не изменены.Experience 2. The process carried out by the proposed method. The same solution was taken as in the first experiment, with a voltage of 40 kV, a discharge capacitance of 1.2 microfarads of impulse energy 530 J, a discharge duration of 35 psec; Other conditions of experience are virtually unchanged.
Результаты обработки 200 импзльсами в расчете на объем пробы 1000 мл: степень разложени оксибензола 24%, энергетический выход разложени , не измененный на прот жении всей обработки, 0,15 молекулы/100 эв. 3 Предмет изобретени Способ очистки промышленных и сточных вод от фенола путем воздействи па очищаемые стоки импульсными электрическими раз- 5 4 р дами, отличающийс тем, что, с целью повышени степени очистки, процесс осуществл ют при энергии одиночного импульсного электрического разр да от 500 до 2000 дж и длительности разр да от 10 до 1000 мксек.The results of treatment with 200 impls per 1000 ml sample volume: the degree of decomposition of oxybenzene is 24%, the energy yield of decomposition, not altered during the whole treatment, is 0.15 molecules / 100 eV. 3 Subject of the Invention A method of purifying industrial and wastewater from phenol by applying steam to cleaned wastewaters with pulsed electric sections, characterized in that, in order to increase the degree of purification, the process is carried out with a single pulsed electric discharge energy from 500 to 2000 j and discharge duration from 10 to 1000 microseconds.
