Progress of Research on Pollutant Transport Transformation and Traceability Methods in Watersheds
Tracing the source of pollutants and understanding their transport and transformation process is very important for the establishment of appropriate management systems and effective control of water pollution in watershed ecosystems.The main different sources of pollutants in the watershed including domestic,agricultural,industrial sources and centralized wastewater management measures were briefly described.By the summarized the main transport modes of pollutants in river basins,the transformation patterns between different forms of nitrogen,phosphorus and heavy metals,and the research progress in exchange modeling at the interface of water and sediment,as well as analyzed the main pollutant traceability techniques and the applicability of these techniques.It also put forward several suggestions for future research work to provide some reference for watershed pollution traceability research.
