| Abstract: |
| Based on the established pollutant emission intensity assessment model of enterprises in key industries, and according to the site pollution emission situation in Tianjin, a total of 25 representative enterprises from five key industries in Tianjin (petrochemical, pesticide, coating, steelmaking and electroplating) were selected to test the model. Through the evaluation method, the pollutant control was analyzed for each enterprise, and then the evaluation index system was constructed and calculated. The measurement results were compared with the measured results to verify the applicability of the emission intensity evaluation model in different industries and further improve the evaluation technology and method system. The results show that 24 enterprises belong to medium intensity emission, and one petrochemical industry enterprise belongs to high intensity emission. The calculated results also have the overall consistency with the comparison results of the risk screening scores of each enterprise and the measured proportion of optimal control pollutants. There are differences in individual enterprises, but the situation is basically consistent, and the overall error is within the acceptable range. This study can provide reference for the assessment and calculation of emission intensity of site pollution sources, and provide technical support for site soil environmental management in areas with rapid economic development. |
