Analytic Hierarchy Process in Comprehensive Evaluation of Water Environment Treatment for Baiyangdian Lake

The available and adaptive technologies to Baiyangdian Lake water environmental management were assessed by adopting the analytic hierarchy process(AHP) in combined with the characteristic of water quality from Baiyangdian Lake.These techniques contained 24 kinds of technical proposal,separated from three major categories,including sediment pollution control,water purification and nutrient control.Firstly,the 24 technologies were evaluated according to the purification effect,economic benefit,operation and management performance,and eco-efficiency.Then,a comprehensive evaluation system including 4 layer,11 indexes and 24 schemes was established by AHP to select the optimalizing technical solutions.The results indicated that eco-efficiency of constructed wetland with optimal,technical and economic benefits of submerged plants harvest was the best and chemical adsorption is the most reliable in operation and management under the premise of ensuring purification effect.
