Изобретение относитс к способам очистки сточных вод от поверхностно-активных веществ и может быть использовано при очистке сточных вод предпри тий легкой промышленности , производства синтетического каучука , бумажной промышленности.The invention relates to methods for the purification of wastewater from surfactants and can be used in the purification of wastewater from light industry enterprises, the production of synthetic rubber, and the paper industry.
Известен способ очистки сточных вод от поверхностно-активных веществ (ПАВ) диспергированием воздуха, отделением образовавшейс пены и ее сжиганием. По такому способу пена разрушаетс медленно, поэтому необходимо примен ть нагревание.A known method of cleaning wastewater from surface-active substances (surfactants) by dispersing air, separating the resulting foam and burning it. By this method, the foam is destroyed slowly, so it is necessary to apply heat.
Известен способ очистки сточных вод от ПАВ барботированием воздуха через жидкость , отделением пены, ее гашением и введением адсорбента во флотоконденсат.A known method of purification of wastewater from surfactant by bubbling air through a liquid, separating the foam, quenching it and introducing the adsorbent into the flotation condensate.
С целью ускорени и упрощени процесса очистки предложено адсорбент вводить в пену.In order to speed up and simplify the cleaning process, it has been proposed to introduce the adsorbent into the foam.
В результате адсорбции ПАВ из пены последн тер ет прочность и быстро разрушаетс .As a result of the adsorption of surfactants from the foam, the latter loses its strength and quickly collapses.
Вли ние добавок порошкообразного адсорбента , активированного угл АУ, на скорость разрушени пены с содержанием ПАВ ОП-10 1000 мг/л жидкости, полученной в результате разрушени пены, показано в таблице.The effect of additives of powdered adsorbent, activated carbon AU, on the rate of destruction of the foam with the content of surfactant OP-10 1000 mg / l of the liquid obtained as a result of the destruction of the foam is shown in the table.
Данные, приведенные в таблице, показывают , что при введении адсорбента в пену последн разрушаетс в 21-28 раз быстрее, чем без него.The data in the table shows that with the introduction of the adsorbent into the foam, the latter is destroyed 21-28 times faster than without it.
Концентраци ПАВ в жидкости, полученной в результате разрушени пены по предложенному способу, может быть в зависимости от дозы адсорбента доведена до концентрации, равной концентрации ПАВ в сточной воде до очистки или после нее. В зависимости от остаточной концентрации ПАВ после обработкиThe concentration of surfactant in the liquid obtained as a result of the destruction of the foam according to the proposed method can be adjusted, depending on the dose of the adsorbent, to a concentration equal to the concentration of surfactant in the waste water before or after treatment. Depending on the residual surfactant concentration after treatment
адсорбентом жидкость, полученна в результате разрушени пены, может быть присоединена к исходной сточной воде или к очишенной воде. Пример 1. В стекл нную колонку (диаметром 40 мм и высотой 50 мм) с впа нным дном из пористого стекла (стекл нный фильтр № 4) наливают 500 мл раствора, содержащего 50 мл/л ПАВ ОП-10. Затем через раствор пропускают диспергированный пористый пластиной воздух с интенсивностью 3,8 мин, а образующуюс пену через отводную трубку в пробке колонки собирают в стакан с ра;мной мешалкой, совершающей 60 об/мин. Перед включением мешалки в пену ввод т 3 г/л порошкообразного угл и перемешивают в течение 10 мин. Жидкость, образовавшуюс в результате разрушени пены, отфильтровывают от угл . Остаточна концентраци ПАВ ОП-10 в жидкости 7,6 иг/л.the adsorbent liquid resulting from the destruction of the foam can be attached to the original wastewater or to the treated water. Example 1. A 500 ml solution containing 50 ml / l of OP-10 surfactant is poured into a glass column (diameter 40 mm and height 50 mm) with a flat bottom of porous glass (glass filter No. 4). Then, dispersed porous plate with air of 3.8 minutes is passed through the solution, and the foam formed through the branch tube in the column tube is collected in a beaker with pa; I am stirring at 60 rpm. Before switching on the agitator, 3 g / l of powdered coal is introduced into the foam and mixed for 10 minutes. The liquid resulting from the destruction of the foam is filtered off from the coal. The residual concentration of OP-10 surfactant in a liquid is 7.6 g / L.
