由于城市排水管道沉积物易引发管道堵塞、超负荷排放、早期溢流和大量污染物进入受纳水体等一系列问题,开展排水管道沉积物的研究、量化沉积污染物污染负荷、研究沉积物的运移规律对管道出水水质的改善具有重要意义。阐述了排水管道沉积物的来源、构成特性及危害,综述了国内外对管道沉积物的基础性研究,主要介绍了排水管道沉积物冲刷、淤积和污染负荷模型的研究进展,并根据我国排水管道的现状进一步分析了该领域的研究重点及难点。
Because of urban drainage pipe sediment easily lead to pipeline blockage, overload discharge, early overflow and a large number of pollutants into the receiving water and a series of problems, to carry out drainage pipe sediment research, quantify the deposition of pollutant pollution load, sediment research The rule of migration is of great significance to the improvement of water quality of pipeline. The origin, formation characteristics and hazards of drainage pipeline sediments are expounded. The basic research on pipeline sediment at home and abroad is reviewed. The research progress of drainage pipeline sediment erosion, deposition and pollution load models is mainly introduced. According to our country drainage pipeline The status quo further analyzed the research focus and difficulty in this field.
