Sediment risk analysis of urban drainage pipeline

Abstract

The urban water body is an important part of the urban infrastructure, and the urban drainage pipe is the core part of the urban water system, however, heavy metals and nutrients such as nitrogen and phosphorus in the sediments of urban drainage pipes have some risks, so it is important to analyze the risk of sediments in urban drainage pipes. This paper analyzes the risk and harm of sediment in drainage pipeline from three aspects: human health, water ecological safety and water environmental quality, it will lay a foundation for further study on the risk of sediment in drainage pipeline to water environment.
