Abstract
1. СПОСОБ ОЧИСТКИ СТОЧНЫХ ВОД ОТ КАТИОННЫХ ПАВ флотацией в присутствии диспергированного органического реагента, отличающийс тем, что, с целью повышени степени очистки, в качестве органического реагента используют твердый парафин, а процесс ведут при рН 10-12. 2. Способ по п. 1,отличающ и й.с тем, что диспергирован ный парафин ввод т в количестве 100 мг/л.1. A method for purifying waste water from cationic surfactants by flotation in the presence of a dispersed organic reagent, characterized in that, in order to increase the degree of purification, paraffin wax is used as an organic reagent, and the process is carried out at pH 10-12. 2. The method according to claim 1, wherein the dispersed paraffin is administered in an amount of 100 mg / l.

Перемешивают в течение 2 мин и подают воздух со скоростью 100 в течение 5 мин, рН среды измен ют от- 9,5 до 12,5. Воду анализируют на содержание АНП-2 и парафина. Полученные результаты представлены в табл. Г, Пример 2. Дл определеJl i nмc , ДЛЯ определе- ни оптимального количества вводи .«.«- -..г Moro парафина провод т опыты при одинаковом содержании катионного ПАВ 100 мг/л и рН среды. Полученные результаты представлены в табл.2. Т а б л и ц а 100 1 1 The invention relates to the treatment of wastewater and can be used in the chemical and petroleum refining industry. The purpose of the invention is to increase the degree of purification of wastewater Example 1. A 1 liter solution containing 100 mg of ANP-2 is contained in the flotation cell; - - - - .l. primary aliphatic amines with a chain length of 10 to 16 carbon atoms, ORIflnf InPGCH, 100 mg of ultradispersed solid paraffin (particle diameter 4-8 µm, 802 10 g per 1 liter of vrda. Mix for 2 minutes and air is supplied at a rate of 100 for 5 minutes, the pH of the medium is changed from 9.5 to 12.5. Water is analyzed for the content of ANP-2 and paraffin. in Table. G, Example 2. To determine Jl i nc, To determine the optimal amount of inject. "." - -. and the same content of cationic surfactant 100 mg / l and pH of the medium. The results obtained are presented in Table 2. Tabl 1
ПАВ - цетазол, концентраци в сточной воде 50 мг/л, концентраци парафина 50 мг/л. Surfactant - cetasol, the concentration in the waste water 50 mg / l, the concentration of paraffin 50 mg / l.
