Analysis of electrokinetic sedimentation of dredged Welland River Sedient

摘要

the Welland River is a tributary of the Niagara River. In the late 198-0s it was discovered that a section of the Welland River was contaminated with heavy metals as a results of two sewer outfalls that has been used by a steel plant and local industrial and municipal operations for the last 50-60 years. One of the major problems encountered in the treatment of the dredged Welland River sediment is a slow rate of sedimentation due to the large proportion of fine solids in the sediment.
