The analysis of the environmental impact of the largest enterprises located in the Southern and Northern industrial zones of the linear city of Volgograd has been carried out, and the need to change approaches to designing a comfortable urban environment, which currently take into account the average data for characterizing the ecological state of a particular territory, has been shown. The analysis confirmed the need to take into account the local impact of industrial enterprises on the components of the urban environment when justifying the selection and planning of appropriate modern spaces within the framework of the Federal Project "Creating a comfortable Urban environment".

As part of the analysis of the environmental situation on the territory of the Russian Federation in 2023, it was found that in 120 cities the level of atmospheric air pollution exceeds the permissible hygienic standards. Industrial areas are considered "hot spots" where various air pollutants are generated as a result of ongoing industrial activity. An assessment of the NDVI index values and the compliance of the landscaping area of the sanitary protection zones of the largest enterprises of the Northern Industrial Zone of Volgograd, located in the immediate vicinity of residential buildings, with established regional standards was carried out. The data obtained showed low values of the NDVI index and non-compliance of the landscaping area with the established requirements, which confirms the need for systematic monitoring of the condition of green spaces, the implementation of projects for landscaping sanitary protection zones, taking into account the resistance of the rock composition of plantings to harmful impurities contained in the ambient air of the plant.

The paper reveals the problem and causes of the formation of fetid compounds in the systems of transportation and wastewater treatment. Various methods used at the moment to eliminate and neutralize unpleasant odors, as well as a number of measures to clean the air from fetid compounds are considered. A new method is described to prevent the formation of odors of fetid compounds in wastewater transportation and treatment systems and a device for its implementation using low-intensity cavitation. The scheme of the device for sewage treatment from smells of fetid compounds. The principle of operation of this installation is described.
