An Interval Optimization Model of Regional Pollutant Total Amount Control Based on a SEM Total Control Evaluation Index System

摘要

Facing serious environmental forms and combining structure, engineering and management emissions reduction (SEM), this paper had drew up a SEM total control evaluation index system, and built an interval optimization model of regional pollution total amount control which minimized the emission reduction costs. Through the application of model case, the interval optimal model had obtained a reasonable scheme. The minimum total costs of emission reduction was [461.51, 531.19] (10~8 yuan), decreasing -1.75%~11.59% comparing with the recommended scheme (522.03, 10~8 yuan), while the maximum emissions reduction of COD, NH_3-N, SO_2 and NOx were [42.58,48.32], [6.92, 7.80], [30.72, 34.96], and [23.21,26.78] (10~4 tons). The interval optimal result provides policymakers an excellent decision, expands the range of macro-decisions and controls countermeasures for pollutant total amount control program.
