Screening of Best Available Techniques for Lead Smelting Pollution Prevention and Control

The related policies of lead pollution prevention and control in abroad, the best available techniques (BATs) for lead smelting pollution prevention and control of European Union, and the current smelting techniques of lead in China were briefly analyzed. A method integrating analytical hierarchy process (AHP) with the fuzzy comprehensive evaluation (FCE) was used to screen lead smelting pollution prevention and control technologies. In the method, the weights of various evaluation indices were determined by AHP and the lead smelting pollution prevention and control technologies assessed by FCE. Based on the AHP-FCE, the best feasible technique portfolio of lead smelting pollution prevention and control was put forward.
