Abstract

Urban runoff pollution has caused serious problems to the water environment. As a structure for collecting runoff, municipal inlet can be transformed into pollution interception facilities at the source. The test added a pollution interception net basket to the grate inlet, and sampled the influent and effluent of grate inlet from rainfall events. The results showed that the composition of runoff pollutant was complex. In the beginning of rainy season and when the interval was long, the pollution load of runoff was particularly serious. The removal device was mainly based on physical interception, the removal efficiency of SS was better,the average removal efficiency was 54.5%, and the removal efficiency of COD and other pollutants was relatively lower. As a simple purification measure, the decontamination device could be applied to the municipal water outlet in the newly built, rebuilt and expanded areas, and play a role in management of runoff pollution and black and odor water bodies.
