Claims (3)

1. Способ очистки сточных вод включает подготовку активированной газожидкостной смеси на основе поверхностно-активных веществ (ПАВ) и последующую флотацию, отличающийся тем, что ПАВ в перемешивание вводят перед подачей диспергированного воздуха при концентрации раствора не ниже критической концентрации мицеллообразования.1. The method of wastewater treatment includes preparing an activated gas-liquid mixture based on surface-active substances (surfactants) and subsequent flotation, characterized in that the surfactant is introduced into the mixing before feeding dispersed air at a solution concentration not lower than the critical micelle concentration. 2. Способ по п. 1, отличающийся тем, что активность газожидкостной смеси достигается временем ее выдержки до образования предельного адсорбционного слоя реагентов на границе раздела жидкость - газ. 2. The method according to p. 1, characterized in that the activity of the gas-liquid mixture is achieved by its exposure time until the formation of the maximum adsorption layer of the reactants at the liquid-gas interface. 3. Способ по п. 1, отличающийся тем, что в приготовленную активированную газожидкостную смесь до подачи ее во флотационную камеру вводят дополнительную воду в пропорции 1:3-1:11. 3. The method according to p. 1, characterized in that in the prepared activated gas-liquid mixture before feeding it into the flotation chamber, additional water is introduced in a ratio of 1: 3-1: 11.
