The paper took river sediment as research target and carried out the reuse of sources through the solidification to sediment. First ,it optimized the prescription of solidifier,and took compressive strength as the index. Based on the traditional solidifiers such as cement, fly ash and lime,the paper added sodium carbonate or calcium sulphate so as to further enhance the strength of solidified cement,the paper compared the effects of a few of pre-treatment methods on sediment solidification.Result showed that Fenton treatment and heat treatment are able to reduce the organic content of sediment and to improve the strength of material after solidification.The effect of heat treatment is the best. The compressive strength of solidified sediment after treatment of 300°C is more than 1 MPa,and meet the requirement for filling materials.At the same time the heavy metal in sediment after solidification can′t leach and is safe to the environment.
