摘要：

将层次分析法与灰色综合评价法相集成，形成了用于评价炼化达标外排污水深度处理回用技术的新方法。该方法以多层次分析模型为骨架，利用熵权法获得指标权重，并通过求取灰色关联度建立了炼化污水深度处理回用技术评价模型，减少了人为因素的影响，使评价结果更加客观和具有指导性。通过实际案例，给出了该模型的计算流程及评价方法。

Abstract:

By combining AHP with grey comprehensive evaluation methods,a new method for the assessment of effluent reaching the refinery standard in the advanced treatment and reuse of refinery wastewater has been formed. Based on the AHP as a frame,the index weight is obtained by entropy method,and the evaluation model of refinery wastewater advanced treatment and reuse processes have been established by obtaining grey association degree. Since the influence of artifical factors are reduced,the evaluation result is more objective and instructive. According to the real case,the evaluation method and calculation procedure of the model are introduced.

Key words: refinery wastewater, reuse techniques, evaluation method
