城市合流排水管道水-沉积物界面污染研究进展
Research progress on the pollutant from the water-sediment interface in urban combined drainage pipes
摘要
Abstract
Pollutant from sediment in the combined drainage pipes has been a main source of the non-point source pollution for the receiving water.Hence,it is of great importance to study the action of the pollutant from the water-sediment interface.The composition of the water-sediment interface,the pollutant characteristics,and the simulation model of the interface of the water-sediment were reviewed.The water-sediment interface pollutant can be divided into the organic layer,the near-bed solid layer and the fluid sediment layer.Both the organic layer and the near-bead solid layer have relatively high organic content and high water content,while the fluid sediment layer has high concentration of volatile matter.It can be concluded that the erosion resistance of the water-sediment interface pollutant is weak,and the water content is the main factor which affects the shear stress of the water-sediment interface.Besides,the existing research on model simulation of the water-sediment interface mainly focuses on predicting the contribution of the near-bed solid on the initial flushing,the pollutant erosion of the organic layer,and the biological degradation of the near-bed solid layer.It is advised that the pollutant characteristics of the water-sediment interface needs further study,and the local water-sediment interface pollution contribution model needs to be established.关键词
