description: The theme of the master's thesis is "Modernization of wastewater treatment systems of pulp and paper industry enterprises". The purpose of the master's thesis is to study the problem of pollution of water bodies by wastewater from pulp and paper enterprises and the development of measures for the modernization of water treatment facilities to reduce the negative impact on water bodies. Tasks set and carried out in the course of the study: Study the theoretical foundations of the impact of the pulp and paper industry on the environment. Conduct a comprehensive analysis of the impact of the activities of JSC Â«Mondi Syktyvkar LPKÂ» on a nearby water body. Develop and substantiate measures to improve the system of water treatment facilities at the enterprise JSC Â«Mondi Syktyvkar LPKÂ». Make an economic justification for the proposed activities. The work was carried out on the basis of the data of JSC Â«Mondi Syktyvkar LPKÂ», provided by the department of environmental protection from the enterprise, as well as from open Internet sources. A review of the wastewater treatment plant system was carried out, as well as an analysis of the pollutant components in the discharged effluents prior to the modernization. Solutions for minimizing the damage to water objects from polluting were considered, an exhaustive comparative description of the equipment for the introduction into the system of water treatment plants was presented. As a result of the study, the choice of equipment for the disc filter system and its implementation at the stage of deep treatment was proposed and justified, as well as a diagram of water treatment facilities and an analysis of the indicators of polluting components in treated effluents after the introduction of this equipment. Finally, an economic justification for these activities was carried out according to the calculations of environmental and economic damage, as well as total payments for compensating for the negative impact on the water body.
