摘要
Abstract
Nutrients and heavy metals are important sources of river and lake pollution.This study takes a certain section of the river as the object,analyzes the pollution of nutrients and heavy metals in the sediment of the river,explores the scope of ecological dredging and evaluates the implementation effect of ecological dredging projects.The results showed that the ecological dredging project had significant effects in removing nutrients and heavy metals from sediment.The dredging project reduced the nutrient content in river sediment from the"lowest level"to the"safe level",and the ecological risk index level of heavy metals decreased from"medium risk"to"low risk".Ecological dredging effectively reduces the accumulation of nutrients and heavy metals in river sediment,with significant benefits.关键词
