Study on Assessment Method of Emergency Disposal Technology Based on Threat Evaluation

Abstract:

s:In order to predict the harm of sudden pollution to source water,screen out appropriate emergency disposal technologies,an evaluation index system of emergency treatment technology in urban drinking water source based on threat evaluation was established by analytic hierarchy process (AHP) from the points of pollution situation,pollution position,water source scale,emergency management and alternative water source.Threat was divided into four levels, and different threat-levels corresponded with different weight of the evaluation index system of emergency disposal technologies. When pollution event occurred, emergency experts graded every index, got the threat-level according to the linear weighted method and selected corresponding set of weights of the emergency disposal technologies The method proved to be an scientific and accurate.
