Abstract: In order to scientifically evaluate groundwater pollution treatment processes, a fuzzy analytic hierarchy process evaluation method for groundwater pollution treatment processes is proposed. Firstly, select the initial evaluation indicators and use fuzzy clustering algorithm to cluster them to eliminate redundant indicators; then, a scientific evaluation index system for groundwater pollution treatment process is constructed, and the fuzzy analytic hierarchy process is used to calculate the weight values of each evaluation index. A fuzzy mathematical comprehensive evaluation model is constructed, and finally, the evaluation of groundwater pollution treatment process is completed based on the calculation results of index weight and the fuzzy membership matrix. The experimental results show that this method can accurately evaluate different groundwater pollution treatment processes, and the application effect of the upflow anaerobic sludge bed process is the best. After its treatment, the pollution degree in the study area has decreased by more than 60%.

Keywords: fuzzy analytic hierarchy process; FAHP; groundwater; pollution treatment; fuzzy clustering algorithm; evaluation index system; weight value.
