“…У водні об'єкти України щорічно потрапляє понад 2,5 млрд м 3 забруднених стічних вод, які вміщують у собі 7,5 млрд різних забруднень. У багатьох водоймах в небезпечній кількості містяться важкі метали, пестициди, інсектициди, мінеральні добрива, феноли, які мають негативний вплив на воду та рибу (DSTU HOST 27384:2005;Malovanyi et al, 2020).…”

There are only 15 % of water reservoirs in Ukraine that can be used as sources of water supply, taking into account water treatment facilities. 55 % of polluted objects and 30 % very dirty, water from these sources cannot be used even after cleaning. With the help of sanitary-hygienic, ecological and water management assessment, they ensure the quality of water in the impact on the environment and the quality of fish products. The main documents that determine the quality, properties and chemical composition of drinking water are DSTU 7525:2014 and DSTU 27384:2005, they specify the main toxicological and organoleptic concentrations of chemicals that must be contained in water. The standard “Sources of centralized economic drinking water supply, hygienic and ecological requirements for water quality and selection rules” makes it possible to develop a complex of interrelated standards and norms, including the use, protection and restoration of water resources, objective assessment of the ecological state and quality of surface and underground waters and their compliance with the requirements of EU standards. Water treatment equipment and technologies used nowadays for wastewater treatment do not provide a sufficient degree of purification and disinfection. Surface water reservoirs, along with impurities of natural origin, contain chemical pollution – heavy metals, pesticides, insecticides, oil products, phenols. The methods of wastewater disinfection are divided into chemical, physical, physico-chemical and in the conditions of artificial and natural biocenoses.

A systematic modern analysis of the state of waste management in the country encourages the search for more rational, efficient and cost-effective ways of processing and recycling solid waste. The inclusion of sewage sludge as a raw material in technologies for processing substrates makes it possible to solve the problems of accumulation and negative environmental impact of this hazardous waste, in addition to the problems of recycling. Promising strategies for the use of sewage sludge in combination with other components for reclamation purposes are considered: the production of substrates by direct mixing without any physical and chemical transformation of the substrate before application for reclamation purposes; composting to obtain reclamation compost; preliminary anaerobic biodegradation with the formation of biogas and subsequent use of digestate for reclamation purposes. The conditions for the application of the strategies, their advantages and disadvantages are analyzed.
