Environmental assessment of a «water body – effluent discharge» scheme

Summary

During the studies an approach to the environmental assessment of a «water body-effluent discharge scheme» was developed. Probability of meeting the design performance of biological treatment and environmental requirements at small-scale municipal wastewater treatment facilities was evaluated. Maximum permissible concentration exceeding factor both in effluents and river water before and after discharging by the example of the Vologda Region case study was determined. Relationships between hydraulic and chemical parameters of effluent receiving bodies and discharged effluents were defined.
