the study addresses the environmental risks associated with the use of chlorine-containing reagents (formation of toxic organochlorine compounds - OCs) for wastewater disinfection at the treatment plant (WWTP) in Almetyevsk. The aim is to develop an engineering and technological solution to replace chlorination with ultraviolet (UV) disinfection. A comprehensive analysis of wastewater quality at various treatment stages (determination of suspended solids (SS), BOD₅, petroleum products, nitrates, ammonium ions) was performed using standardized methods (gravimetry, titrimetry, chromatography, photometry). The existing technological scheme of the WWTP with a capacity of 40 thousand m³/day is described. Based on the analysis, the integration of UV units as a final disinfection stage is proposed. This will eliminate the formation of OCs, increase the environmental safety of treated effluent discharge into the receiving water body, and ensure compliance with modern environmental regulations.
Keywords:Wastewater disinfection, ultraviolet radiation, organochlorine compounds (OCs), environmental risk, wastewater treatment plant (WWTP), sodium hypochlorite.
