AB  - As an environmentally friendly and controllable technology, Microbially induced 
      carbonate precipitation (MICP) has broad applications in geotechnical and 
      environmental fields. However, the longitudinal dispersivity in MICP 
      multi-process varies with the scale size. Ignoring the effect of the scale size 
      of the research object on the dispersivity leads to the inaccuracy between the 
      numerical model and the experiment data. Thus, this paper has established the 
      relationship between the scale size and the dispersivity initially, and optimized 
      the theoretical system of MICP multi-process reaction. When scale size increases 
      logarithmically from 10-2 m to 105 m, longitudinal dispersivity shows a trend of 
      increasing from 10-3 m to 104 m. The distribution of calcium carbonate is closer 
      to the experimentally measured value when the size effect is considered. After 
      considering the scale size, the suspended bacteria and attached bacteria are 
      higher than the cased without considering the size effect, which leads to a 
      higher calcium carbonate content. Scale has little effect on the penetration law 
      of the suspended bacteria. The maximum carbonate content increases with the 
      increase of the initial porosity, and the average carbonate shows a significant 
      increasing trend with the increase of the bacterial injecting rate. In the 
      simulation of the microbial mineralization kinetic model, it is recommended to 
      consider the influence of the scale size on the MICP multi-process.
