The concept of regulatory support of the environmental safety of surface waters (pilot scheme)

Summary

The concept of regional environmental standards for pollutant concentration in water bodies is presented. The substantiation of a statistical model for calculating regional environmentally admissible pollutant concentrations in the Neva Bay and in the eastern part of the Gulf of Finland is given. The comparison of estimated values of environmentally admissible concentrations with the relevant hygienic and fisheries maximum permissible concentrations showed that they could be more stringent (for phosphorus, ammonia ions, nitrates), less stringent (for BOD5) or coincide with maximum permissible concentration (for nitrites, mercury). The suggested draft calculation procedure of the regional environmental standards got an approval of the Federal Environmental Inspection. The given procedure can be used for water bodies with low mineralization.

Key words

pollutants , environmentally admissible concentration , statistical model , ecological limiting sign of harm , environmentally admissible loadings

The construction of the world biggest effluent disinfection facilities at the Kouryanovo wastewater treatment plant in Moscow

Summary

The drivers for choosing UV-radiation as a basic technology of effluent disinfection at the Kouryanovo and Lyubertsy wastewater treatment facilities are presented. The proven experience of UV-disinfection plant operating at the second line of the Novo-Lyubertsy wastewater treatment facilities gave rise to the next stage of introducing the given disinfection method at the Kouryanovo wastewater treatment facilities. In the course of designing it was decided to retrofit UV-disinfection plant into the existing elevation layout of the treatment facilities by using open-channel UV-plants with vertical lamp position. The specific features of the treatment facilities operation and the condition of the discharge canal also took into account.
