Study on the characteristics of contaminants in urban stormwater runoff and their control
Update time: 2008-01-09 AUTHOR:


The species of contaminants (i.e. organic matter, heavy metals, N/P etc.) in urban stormwater run-off will be analyzed first. The temporal and spatial distributions of these pollutants will be investigated thoroughly to find their transformation mechanisms in stormwater run-off. The reaction processes and relationships among these pollutants will also be studied further to reveal the variations of complex contaminants and their transformation in environments. Moreover, investigation of the key roles and changing processes of contaminants in stormwater run-off will lead to better control and treatment of the pollution. Then the critical treatment technologies will be developed based on the key transfer processes. These will contribute to lower non-point pollution, better protection of natural water and wider utilization of rainwater.
