地表水源突发污染应急处置技术筛选评估体系

Evaluation system for emergency disposal technology insurface drinking water source pollution

摘要:

为应对地表水源突发污染,筛选最优应急处置技术,采用层次分析法（AHP）构建了包含12个评价指标的地表水源突发污染威胁度评估指标体系,用以预判突发污染对水源地的威胁程度；构建了由19个评价指标组成的应急处置技术评估指标体系,依据不同等级的威胁度,确定出与其对应的评估指标权重值；基于多重指标体系的联合评估,确保了筛选评估体系的科学性.通过山西苯胺泄漏污染事故实例对评估体系进行了验证. 结果表明,本文构建的筛选评估体系可对应急处置技术方案进行快速、准确的评估,可为应急专家决策提供有效的技术支撑.

Abstract:

In order to obtain the optimum emergency disposal technology scheme for the pollution of surface drinking water source, a threat-evaluation index system with 12 indicators was established based on analytic hierarchy process (AHP). Meanwhile, the technique evaluation system containing 19 indices was also developed, with different threat-levels corresponded to different weights of each evaluation indicator. The scientificity of the multiple evaluation systems has been evaluated using a sudden aniline pollution accident occurred in Shanxi. Experimental results showed that the evaluation system can assess the disposal technology schemes accurately once the accident occurred, and will provide technical support for emergency experts.
