Abstract

The release of pollutants from the river sediment causes serious secondary pollution to the overlying water.In order to find an effective way to control the release of pollutants from sediment,we studied on the bioremediation of contaminated sediment and its effects on the bioremediation of overlying water through a series of well controlled experiments that deal with the joint implementation method of aeration-bioaugmentation in a continuous flow model river.The results showed that the joint implementation method had a good effect on the sediment bioremediation.This method could effectively improve the activity of the biodegradation of sediment(G value) and reduce the release amount of nitrogen and phosphorus pollutants from sediment.Sediment G value was negatively correlated with the amount of emission of nitrogen and phosphorus pollutants.Aeration,or aeration with bioaugmentation had a good repairing effect on bioremediation of polluted water,but the bioremediation of river sediment had a more obvious impact on the efficacy of water bioremediation.After the sediment bioremediation,bioremediation of water bodies could get a more significant treatment effect.The maximum removal rates of COD and ammonia nitrogen increased from 65.0% and 16.30% to 72.0% and 41.0%,separately,and the water bioremediation cycle was shortened from 13 d to 6 d.
