Effects of River Sediment on the Biodegradation of Organic Pollutants in Domestic Sewage
Complicated physical, chemical or/and biologic interactions exist between sediment particles and organic pollutants in natural water bodies on the water-sediment interface. The sediment plays an important role in the transportation and fate of pollutants. In the present study, two groups of sediment with different particle size sampled from the Yangtze River in China and the organic pollutants in domestic sewage was collected. Laboratory experiments were designed to investigate the effects of river sediment on the biodegradation of organic pollutants in domestic sewage using the method of carbon dioxide evolution test. The results indicated the biodegradation rate with river sediment were larger than that without sediment. The presence of sediment accelerated the biodegradation of organic pollutants. It implies that sediment may speed up the removal of organic pollutants from the domestic sewage and contribute to the ecological restoration in highly-polluted water body.
