АҚАБА СУЛАРДЫ ОЗОН ЖӘНЕ АТМОСФЕРАЛЫҚ ОТТЕГІ АРҚЫЛЫ ТАЗАРТУ

Abstract

With the increasing pollution of industrial wastewater, particularly by petroleum products, the search for effective treatment methods has become an urgent task. The main source of contamination is hydrocarbons, which are difficult to remove using traditional methods. This study proposes a wastewater oxidation method using a mixture of ozone and atmospheric oxygen at various concentrations of a manganese dioxide catalyst. More than 500 experiments were conducted on real water samples from an organic synthesis plant. Comparative analysis showed that ozone provided higher purification efficiency (up to 53%), while treatment with oxygen resulted in a 41% efficiency. In addition, ozone demonstrated superiority in improving light transmittance. The optimal concentration of MnO₂ catalyst for ozone was determined to be 1-2 g/L. The proposed method is environmentally and economically efficient, allows for repeated use of the catalyst, and is promising for treating waters with high concentrations of hydrocarbons.
