Abstract
The impact of wastewater treatment plants on the environment as a result of the release of harmful substances into the atmosphere
Incoming article date: 12.04.2021The emission of pollutants from wastewater disposal facilities has become a topic of increased interest, given its significant impact on the overall climate footprint of wastewater treatment plants. This paper presents comparative data in the field of air quality monitoring on the territory of domestic and industrial wastewater treatment plants abroad and in Russia. The issue of the influence of odors on human health is considered. Practical examples of the control of bad-smelling emissions are offered. A brief review of scientific papers on topics related to gaseous emissions from wastewater disposal systems is presented. Experimental studies of the quantities of specific components of the gas-air mixture above the surface of the waste liquid of the aeration tanks of the sewage treatment plants (CBS) of the city of Novoshakhtinsk, Rostov region are presented. Based on the analysis of the obtained results, technologies for reducing the amount of emissions from CBS facilities are considered.
