Characteristics and control measures of urban road stormwater runoff

Urban nonpoint source pollution caused by rainstorm runoff washing off has been the main pollution source of receiving water body.Based on related literature at home and abroad,the pollutant composition in urban rainstorm runoff as well as their pollution levels under different environment is analyzed.Meanwhile,the factors influencing the water quality of rainstorm runoff are also discussed.Control measures of urban rainstorm runoff are also discussed.Determining initial runoff volume reasonably,selecting and designing control technologies scientifically and integrating urban planning and urban rainstorm runoff control technologies together to form regulatory network would be the feasible way for the control of urban rainstorm runoff pollution.
