A Study Method of Ecological Risk Evaluation for Reclaimed Water
According to characteristics which generate from reclaimed water for ecology environment, we utilize event tree analysis (ETA) method to analyze the risk transmission way of reclaimed water, on the base of it, the evaluation index system which reclaimed water for ecology environment effect is preliminary established, and indicator weight is determined by entropy value method. Finally, we set up comprehensive evaluation model using entropy value and gray connection method, combine with the risk matrix to qualitative describe the risk level of comprehensive evaluation result.
