Scope

Main technical content: This document is applicable to the comprehensive evaluation of wastewater treatment technologies and water body restoration technologies on a pilot-scale or above. The comprehensive evaluation results can be used as a reference basis for technology selection, technology integration, and technology forecasting. For the characteristics of water pollution control technologies, a four-level comprehensive evaluation index system is constructed, including "target layer-criterion layer-element layer-indicator layer". According to the technical field of the evaluation object, relevant information is collected to prepare for the evaluation. Based on the characteristics of the evaluation object, an alternative indicator database is established, and the evaluation indicators are screened and the indicator data are obtained to establish an indicator database. Comprehensive evaluation calculations are carried out, and the indicator data are normalized using standardization calculations. The weights are assigned using the analytic hierarchy process and the entropy weight method to conduct comprehensive evaluation calculations. The evaluation scores are calculated from three dimensions: environmental, economic, and technical. The results of the comprehensive evaluation are expressed and analyzed using three-dimensional coordinate charts and radar charts.
