Description
Изобретение относитс к способам очистки сточных вод и может быть использовано дл очистки промышленных стоков. Известен способ очистки сточных вод от небелковых органических соединений обработкой агентом, перевод щим органические соединени в твердую фазу, обладающую поверхностной активностью, с последующей ее флотацией. Использование известных катионных и анионных собирателей не позвол ет очищать сточиые воды от гуминновых кислот. С целью устранени указанного недостатка обработку сточной воды провод т ацетатОлМ алшна капифоли. Это позвол ет растворенные в воде гуминновые кислоты перевести в твердую фазу, обладающую поверхностной активностью. Флотацией твердой фазы можно достигнуть очистки сточных вод от гуминновых кислот на 75-85%. П р и м е р. В флотационную колонку, представл ющую собой цилиндр диаметром 35 мм и высотой 300 мм, дном которой служит фильтр Шотта ЛГ 4, заливают 250 мл водного раствора гуминновых кислот с перманганатной окисл емостью 100 мг/л. Затем в колонку ввод т 10 .ил 0,4% водного раствора ацетата канифоли. После чего в колонку через фильтр Шотта подают воздух со скоростью 90 . Процесс продувки раствора воздухом (флотацию) провод т в течение 25-30 мин. Остаточна пермангапатна окисл емость раствора -14 мг/л. Предмет изобретени Способ очисткп сточных под от органических соединений обработкой агентом, перевод щим органические соединени в твердую фазу, обладающую поверхностной активностью , с последующей ее флотацией, отличающийс тем, что, с целью очистки от гуминновых кислот, обработку стоков ировод т ацетатом амина канифоли.The invention relates to wastewater treatment methods and can be used for the treatment of industrial effluents. A known method of treating wastewater from non-protein organic compounds is treated with an agent that converts organic compounds into the solid phase, which has surface activity, followed by flotation. The use of known cationic and anionic collectors does not allow purification of waste water from huminic acids. In order to eliminate this drawback, the treatment of waste water is carried out with acetypholamine. This allows the huminic acids dissolved in water to be transferred to the solid phase with surface activity. Flotation of the solid phase can achieve wastewater treatment of huminic acids by 75-85%. PRI me R. A flotation column, which is a cylinder with a diameter of 35 mm and a height of 300 mm, the bottom of which is a Schott L4 filter, is poured with 250 ml of an aqueous solution of huminic acids with permanganate oxidation 100 mg / l. Then a 10% or 0.4% aqueous solution of rosin acetate was added to the column. After that, air is flowed at a speed of 90 into the column through a Schott filter. The process of purging the solution with air (flotation) is carried out for 25-30 minutes. The residual permanganate oxidability of the solution is 14 mg / l. The subject of the invention is a method of cleaning waste under organic compounds by treating with an agent converting organic compounds into a solid phase with surface activity, followed by flotation, characterized in that the waste treatment is carried out and the resin is rotated with amine acetate.
