The transportation and treatment of the urban wastewater involves the formation and emission into the environment of fetid substances: sulfur and nitrogen compounds, volatile fatty acids, aldehydes and ketones. Fetidly smelling odors of a sewage system are formed as a result of the anaerobic biological decomposition of organic substances (proteins, carbohydrates), the presence in the wastewater of sulfate-reducing microorganisms that receive energy through the organic substance oxidation. The article considers the methods for determining harmful gaseous substances through chemical and organoleptic analyses, presents a list of the methods used in the Russian Federation and abroad for determining fetidly smelling substances, as well as investigating the advantages and disadvantages of the measures aimed at fighting against fetid odors. Each of the given methods has been implemented using constructional and (or) operational means. It has been stated herein, that the odor neutralization, a correct choice of operational and technical measures, construction technologies, design and hardware solutions (choice of the equipment) require a preliminary surveying of the objects of fetidly smelling substances along the whole pipeline system as part of thorough design and technological studies. The theoretical significance of the research consists in searching for the causes of the gas fetid smells, their intensity control methods and the ways that prevent formation and minimize negative manifestations by construction and operational means. The practical relevance of the performed studies is in a possible application of the got results by the specialists of the sewage system designing and public utility servicing works.
