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.
