In order to probe the properties of contaminated sediment which is solidificated by cement , zeolite and TMT,the paper studied the optimum ratio and conditions of the three components by taking compressive strength, leachate pH and leaching toxicity as indicaters.Results showed that the optimum condition is that the mass ratio of sediment,cement, zeolite and TMT is 1∶0.42∶0.18∶0.04. The compressive strengths of solidified products in 7 , 14 and 28 days are 3.12, 4.07 and 6.28 MPa respectively. Leachate pH value is further reduced. In addition, the amount of heavy metals and CODCr in leachate are reduced by more than 90% and 50% respectively.The compressive strength of the solidified products after 7 days meets the industrial standard and the leaching toxicity satisfied the third grade discharge standard of pollutants for municipal wastewater treatment plant.The result provides the research foundation for the practical application of sediment resource recovery.
