This project focuses on the research and development of new multi-component polymer solidification and remediation technologies for typical heavy metal contaminated sites. Industrial waste materials such as fly ash, mineral powder, kaolinite, and coal gangue are used to prepare a novel geopolymer solidification material through composite excitation technology; by investigating the effects of curing agent dosage and curing age on the solidification and remediation effects of heavy metal contaminated soil, the changes in mechanical properties indicators and microstructure of the soil after remediation with the solidification material are identified; chemical analysis methods and microscopic structure testing methods are employed to reveal the remediation mechanism of heavy metal contaminated soil using multi-component polymers; based on the characteristics of microstructure changes, the degradation model of solidification body strength indicators, and the leaching model of heavy metal ions, a method for evaluating the remediation effects of multi-component polymer solidified heavy metal contaminated soil is established, and the long-term stability of the remediated soil is assessed.
