Source identification concept within a framework of urban drainage master plans

摘要

The on-going all-society development brings along a fundamental negative effect - a continuous degradation of the environment. Growing urbanization and a denser transportation network change the aboriginal character of the landscape. These substantial changes to the environment force ecological and hydrological processes to change as well. With the change of the ecological and hydrological processes new, usually very specific problems arise. A worsening quality of surface water, groundwater and air quality are amongst the most alarming manifestations of these problems. The level of pollution of these basic environmental attributes then subsequently influences other aspects of life of today's society. The production of wastewater, its treatment, discharge and disposal are all part of all inter-linked system and they altogether form a main factor that determines the quality of the receiving waters.
