Background

With the rapid development of industrialized urbanization, a large amount of wastewater and polluted surface runoff cannot be collected and treated to be directly discharged into rivers, and in addition, the treatment rate of agricultural rural wastewater is low. The intake of river pollutants exceeds the self purification capacity, and the river channel has black and odorous phenomena.
