Sources and erosion of organic solids in a combined sewer

摘要

Sewer deposits play a significant role as a source of pollution in combined sewer overflows. The objective of this paper is to identify, using a direct approach on a sewer length, the main source of organic solids among the different deposits and their erosion processes. The different deposits studied were large inorganic solids at the bottom of the sewer, biofilms on the walls of the sewer and organic solids at the water-bed interface.
