Fuente: WIPO "sustainability" The invention discloses a sustainability evaluation model for repairing an organic pollution site by an in-situ heat treatment coupling chemical method, which comprises the following steps: calculating a sustainability total score of an in-situ repairing scheme of the organic pollution site by using an LCA-BMPs comprehensive model, and judging sustainability according to the total score; the method systematically, comprehensively and quantitatively evaluates the sustainability of the environmental, economic and social indexes of the in-situ heat treatment coupling remediation organic pollution site, quantitatively evaluates the environmental sustainability and carbon emission in the remediation process, and obtains a total quantitative sustainable result through an LCA-BMPs comprehensive model. The method breaks the barriers of strong subjectivity of economic and social evaluation of the polluted site remediation technology and weak coupling of sustainable evaluation in three aspects of environmental economy and society, and provides a feasible method basis for environmental, economic and social quantitative sustainable evaluation and comprehensive evaluation of the polluted site remediation technology.
