The application provides a comprehensive decision-making and evaluation method for halogenated
hydrocarbon contaminated soil and
groundwater remediation strategy, comprising: establishing
a site baseline and conducting technical preliminary screening based on health and
ecological risk assessment (HERA) and a three-level evidence
system; conducting rapid
resource efficiency assessment based on environmental
footprint analysis (EFA); conducting global long-term assessment based on
life cycle assessment (LCA) and cost-
benefit analysis (CBA); and dynamic evaluation and closed-
loop control based on digital twinning and multi-criteria decision analysis (MCDA)
coupling. In the dynamic evaluation stage, an adaptive
hybrid dynamic weighting mechanism is constructed, the subjective benchmark weight and the objective fluctuation weight calculated based on real-
time data information entropy are integrated, and the comprehensive utility
score is calculated; at the same time, the apparent degradation rate constant of the
pollutant is solved in real time, and when it is lower than the target rate and the strategy is replaced, the intervention instruction is automatically output. The application realizes the
deep integration of multi-dimensional indicators, dynamic adaptive evaluation and closed-loop intelligent regulation and control, and solves the problems of single, static and lack of feedback of the existing evaluation method.
