It is urgent to deal with the severe problem of heavy metal pollution in landfills using efficient remediation technology. In recent years, the potential of MICP technology to remedy heavy metals has been extensively explored. Sporosarcina pasteurii shows better urease activity and heavy metal tolerance among the indigenous microorganisms. However, few researches have explored the remediation potential of S. pasteurii to heavy metals in high concentration. The efficiency of commonly used bioremediation processes needs to be further improved. In addition, it is difficult to explain the bioremediation mechanism of S. pasteurii to different heavy metals using only MICP theory. To avoid the impact of humus and leachate in the landfill, this study took heavy metal contaminated solutions as the research object and used simple mixing methods to carry out bioremediation experiments. Based on the MICP and chemical equilibrium theory, the Visual MINTEQ software was used to simplify and simulate the bioremediation process. The results show that in the high concentration range, S. pasteurii can efficiently remedy heavy metal Cd, Cr(Ⅲ) and Zn through biomineralization and bioaccumulation. In addition, the simple mixing method is easy to operate, the bioremediation efficiency is high, and it has the potential for engineering applications.
