摘要：

Sedimentation and transportation of mineral and organic pollutants in combined sewer systems are not completely understood. For better understanding, samples of sediment, slime and urban runoff were taken from the combined sewer system of Bad Mergentheim. The settling velocity of settleable solids was measured with a settling apparatus. Typical settling curves for sediment, slime and wastewater were put together. Some of the samples were analysed for heavy metals and organic micropollution to see the relationship between settling velocity and the load of heavy metals of settleable solids. The gained data are of interest for the design of clarifier tanks for stormwater treatment.
