Preliminary Water Purification from Surfactants and Organic Compounds through Ozone Oxidation, Intensified by Electrical Impulses

摘要

The importance of purification of everyday wastes contains in elimination of surfactants (SA) and organic compounds. In this work the results of experimental tests of organic oxidation by ozone, which are amplified by electrical discharges or ultrasound are presented. Circuit diagrams of water purification from surfactants and organic pollutants (OP) are given. Model solutions of sodium lauryl sulfate, as SA, and ethylenediaminetetraacetic acid, as OP are used. The regularities of the influence of pH in the process of electrodischarge and cavitation treatment of OS solutions in the presence of ozone on the quantitative indicators of their destruction were established. The influence of the duration of the treatment process on the persistence of contaminants. The oxidation process was investigated at various concentrations of the initial materials. It has been established that the destruction of surfactants and drugs proceeds better when ozone is combined with the effects of electropulse, at high pH values.
