Laboratory Study of Chemical Coagulation as a Means of Treatment for Dredged Material.

摘要

This report discusses trace metals, chlorinated hydrocarbons, and biostimulants which are found to be enriched in fine particulates of contaminated sediments. When different types of sediments are resuspended, it has been found that the extent of redissolution is very small. However, contaminants attached to the particulates can be transported along the waterways downstream from the disturbed areas. In confined areas, proper treatment and rapid removal of those suspended particulates from the water column will not only lessen the oxygen demand, but will also reduce the input of contaminants into the receiving water.
