Abstract
The article considers the results of studies of the composition and properties of urban wastewater sludge (UWWS) of treatment facilities in 9 different cities of Brest region in three groups of indicators: agrochemical, microbiological, and heavy metal content. A comparison of the data obtained for UWWS with similar indicators for local soils, literature data on the properties of UWWS, comparison with the regulatory requirements for UWWS in the Russian Federation, the EU, the USA, etc. is presented. Shown that with the high fertilizing potential of UWWS in cities of Brest
 region, due to high content of organic and nutrient substances (nitrogen, phosphorus, potassium), the use of UWWS in
 agriculture is limited by its microbiological contamination and high concentrations of heavy metals (zinc, copper, nickel,
 chromium), exceeding maximum permissible concentrations established by the requirements for UWWS in the Russian
 Federation and other countries. Based on the results obtained and the review given in the article about the ways of handling
 UWWS in different countries of the world, an assessment of the suitability of UWWS in cities of Brest region and Belarus as a whole for various types of use is given. With insufficient development of regulatory and legal regulation in the field of the management of UWWS, the most acceptable methods for the conditions of Belarus for the management of UWWS in the medium term are their use for the reclamation of disturbed land, as an insulating layer in landfills of solid municipal waste, in urban and forestry (in floriculture, in parks, squares, nurseries, etc.), and also anaerobic digestion with the production of organic fertilizers and energy.
