Research on the environment-economy-technical comprehensive benefit evaluation method of typical sludge treatment technology

The study aims to evaluate the environmental impact, economic cost and technical performance through sanitary landfill, single incineration, anaerobic digestion and aerobic fermentation, evaluate the environment-economic-technical benefit by using AHP-VIKOR method, and finally the results were tested by TOPSIS method. The results show that aerobic fermentation $\boldsymbol{(\mathrm{Q}=0.0000)}$ is ideal for resource recovery of sludge disposal, followed by anaerobic digestion $\boldsymbol{(\mathrm{Q}=0.2860).}$ TOPSIS test found agreement with VIKOR results and the computational model was stable.
