Estimation of pollutant loads into the water environmental control units in urban areas
城市水环境控制单元污染物入河量估算方法

In areas limited monitoring data, available data should be fully used to estimate and verify the mass of pollutants into rivers. By utilizing the pollution sources census data and land use data, the pollutant loads into the water environment control unit are estimated in consideration of the transport distance of pollutants. The water environmental control unit in the Daliao River, Yingkou City, which is polluted mainly by pollutants from urban areas, is selected to estimate and analyze the pollutant loads into the Daliao River. The results show that the proposed estimation method can be reasonably applied to estimate the pollutant loads into rivers, and the results can provide basis for water environmental capacity verification and policy-making on pollutant load reduction.
