Urban surface runoff pollution is mainly caused by the runoff of pollutants accumulated on sunny days under the action of rainfall. It has the characteristics of random indirect discharge from non-point sources. The control measures are mainly focused on the management and control of the convergence of pollution sources. The method of combining engineering measures is carried out.

Engineering measures: Control pollution through technical measures, i.e. engineering methods, such as the construction of sedimentation tanks, seepage pits, porous pavements, reservoirs, and buildings for dealing with pollution. It mainly includes three aspects: one is the control of the pollution source, and the pollutants in the rainwater runoff are controlled to a minimum from the source; the other is the control of the pollutant diffusion path. measures to reduce the amount of pollutants discharged into underground or surface water bodies; third, terminal treatment, through natural ecological technology or artificial purification technology to degrade the pollutants brought into the water body by runoff.

Non-engineering measures: guide and cooperate with technical measures through various non-technical management measures. Specific measures include diverting water treatment in small areas, increasing urban greening area, cleaning up mixed sewage pipelines, cleaning streets, strengthening waste management on construction sites, machine repair shops, and parking lots, and controlling the use of fertilizers and pesticides in urban green spaces, etc. .
