Introduction. At the modern stage of development of Ukraine problems of air pollution by sewage treatment facilities, especially in resort towns, through dissemination of strong-smelling substances, accumulation of municipal solid waste and pollution of water bodies, where discharges of insufficiently treated wastewater is happening, acquire particular sharpness. Taking into account the necessity in comprehensive solution of all three groups of outlined problems simultaniusly, a purpose of our research was hygienic assessment of work conditions at wastewater treatment plants, using the bioregenerator "Оxydol" produced by Agranco Corporation, USA with some changes made in main technological parameters for their operation.

Materials and methods. In order to modify the processes of biological treating wastewater, entering the municipal waste water treatment plant (WWTP), and to further stabilization and biotechnical processing of solid sewage sludge, following a new technology developed by specialists of O. O. Bogomolets National Medical Universityr "Оxydol" the biogenerator has been used by Agranco Corporation, USA. The following methods have been used for solving the assigned tasks: a bibliographic method of scientific information analysis, methods of prediction and calculations, a method of sanitary inspection, organoleptic, chemical, physicо-chemical, microbiological, hydro-biological and technological methods.

Results. It is found that using the bioregenerator "Оxydol" helps to comletely cease emissions of ammonia, hydrogen sulfide, sulfur dioxide, methane and dioxide and nitrogen oxides to the atmospheric air from operating WWTP. The sludge in settling reservoirs is significantly diluted, the amounts of sediments and sludge, transported to sludge beds is significantly (4–5 times) decreased, so promoting improvement of work conditions at WWTP. At the same time, if certain operating characteristics of WWTP are not changed in due time, the use of the bioregeneratora "Оxydol" will completely cease nitrification and denitrification processes, thus making it impossible to achieve adopted values for allowable discharges. It is established that the bioregenerator "Оxydol" shows its destructive properties in respect of components of domestic waste water, sewage of pig and cattle farms than the similar components of wastewater from distilleries and dairies. The obtained results made it possible to formulate general recommendations to implementation of a new technology for intensification operation of WWTPs in Ukraine.

Conclusions. The bioregenerator "Оxydol" should be used only after making changes in technological parameters for their operation within the frameworks of the provided projects, according to which they have been developed. In order to achieve the most optimal effect for each WWTP a selected combination of microorganisms, enzymes, organic catalysts, should be used, which is unique by its components and/or ratio.
