Abstract
Currently, there is a high level of environmental pollution Urban Territories, which poses a danger to ecosystems and public health, since a significant part of the industrial wastewater generated is discharged into water bodies neither sufficiently purified no without purification. The existing methods for treating effluents containing low concentrations of organic substances are generally quite expensive, long, require significant amounts of reagents or energy-intensive, often accompanied by the formation of secondary pollution and the loss of valuable substances. The scientific significance of the research results lies in the development of the adsorption theory of different nature organic substances by carbon sorbents, which differ in structure and properties of the surface. The values of the adsorption parameters calculated for the investigated active coals calculated from the experimental data can be used in the database of the sorbents' main parameters. The practical importance lies in the choice and recommendations for the practical application of active coals with the best adsorption characteristics, methods for increasing the efficiency of organic components adsorption and obtaining equilibrium data for calculating process parameters of the wastewater treatment process
Highlights
Ensuring cost-effective and environmentally safe water use, protecting water resources from depletion, pollution and degradation is one of the most important tasks of our time
Adsorption methods are characterized by high efficiency, the ability to purify water containing low concentrations of organic substances, up to MPC and below, the ability to allocate valuable products from water (Krasnova, 2011)
According to the obtained experimental data on the adsorption of organic substances from the individual components solutions by different carbon sorbents, adsorption isotherms were constructed as main criteria for evaluating the adsorption properties of the sorbents under the study and made it possible to determine the dependence of the sorbent on the adsorbate concentration and nature under equilibrium conditions
Summary
Ensuring cost-effective and environmentally safe water use, protecting water resources from depletion, pollution and degradation is one of the most important tasks of our time. To protect water resources from pollution, depletion and degradation, it is necessary to exclude wastewater discharge and reduce fresh water intake by creating environmentally safe production facilities with closed water cycles and the disposal of hazardous components. The solution of such problems is possible on the basis of fundamental science development, an integrated scientific and technical approach. Adsorption methods are characterized by high efficiency, the ability to purify water containing low concentrations of organic substances, up to MPC and below, the ability to allocate valuable products from water (Krasnova, 2011). Adsorption plants for water treatment attract attention with its compactness, simplicity of instrumentation and process control, low cost with a high degree of purification
