APPLICATION IN THE AGRO-INDUSTRIAL COMPLEX SCHEMES BASED ON A FLOTATION DEVICE FOR COAL MINING WASTEWATER TREATMENT

QHURJV

Abstract

The relevance of the study is due to the need for effective wastewater treatment of coal mining enterprises, since their composition contains a significant amount of organic and inorganic pollutants. In the context of stricter environmental requirements and an increase in coal production, traditional purification methods do not provide a sufficient degree of purification and require improvement. This article analyzes wastewater treatment technology using a pressure flotation device, which significantly improves the efficiency of pollutant removal, considering the possibility of using treated wastewater in agriculture. The technological scheme of cleaning is presented, including the main and additional stages. The principles of operation of a pressure flotation device, its key design features and mechanisms for removing impurities are considered. The effectiveness of this method was evaluated based on experimental data, and optimal operating parameters of the equipment were identified, allowing minimizing the content of suspended particles and petroleum products in purified water to the parameters allowing the use of purified water in some sectors of the agroindustrial complex. The introduction of this technology will optimize water treatment processes, reduce the burden on the environment and increase the environmental safety of the coal industry.
