Abstract: Dredging is an important method for the treatment of polluted sediment in rivers and lakes. Harmless treatment and resource utilization of dredged sediment in rivers and lakes is an inevitable trend with the raise of the goal of eco-civilization the improvement of laws and regulations in China. The pollution types of sediment in rivers and lakes are classified. On this basis, dewatering techniques, harmless treatment techniques, resource utilization methods and residual water treatment techniques for dredged sediments are discussed. The applicability, advantages and disadvantages of each technique or method are analyzed and compared. The treatment approaches for different sediment types are also summarized. At last, research prospects and advices are given in order to improve the treatment efficiencies for dredged sediment.

Key words: dredged sediment, types of pollution, dewatering, harmless treatment, resource utilization
