基于污染物总量控制的流域水环境 管理绩效优化研究 - 以吉林省招苏台河流域为例

为探寻流域污染物总量控制和水环境管理绩效之间的关系,建立覆盖流域社会、经济、生态的水环境综合管理绩效指标体系,计算环境绩效并分析其变化趋势,以水污染物削减量为决策变量,以投入资金量最小为优化目标,设置环境绩效优化、控制断面水质达标、污染物削减提升的约束条件,构建基于结构、工程、监管提升的流域水环境管理绩效优化模型。以吉林省招苏台河流域为例,利用Lingo8.0软件编程进行优化求解,得到优化方案总投资15.09亿元,COD、氨氮总削减量分别为9 879.1t,619.68t,规划期末水环境管理绩效提升至0.856。水环境管理绩效指标体系可较全面的反映绩效值的定量变化,得到的优化方案满足流域水环境质量改善和污染物总量控制的要求,有效降低资金投入,为流域管理和发展提供参考。

Optimization of water environment management performance based on total amount control of pollutants) A case study of Zhaosutai River Basin in Jilin Province

n or der to ex plor e the relationship between total amo unt contro l of po llutants and water env iro nment manag ement performance, we established a compr ehensive manag ement performance index system for w ater env iro nment co vering so cial, eco2 nomic, and ecolog ical aspects o f the basin. We calculat ed the environmental perf ormance and analyzed its chang e t rend. Taking the r eduction o f w ater po llutants as the decisio n2making v ariable, w ith minimum investment as the optimization o bject ive, we set certain const raints, and built a water environment management performance o pt imizatio n model. Taking Zhaosut ai River basin in Jilin Prov ince as a case study, using Lingo 81 0 sof twar e pr og ramming to optimize the solution, w e obtained an optimizatio n scheme that required a to tal inv est ment o f 151 09 billion Yuan, could reduce the chemical o x ygen demand and ammo nia nit rog en by 98791 1 tons and 619. 68 to ns respectiv ely , and could impr ove the end2o f2term water envir onment management perfo rmance to 01 856. T he perfo rmance index system for w ater env iro nment manag ement can comprehensiv ely r ef lect the quantitativ e chang e of performance value. The optimizatio n scheme meets the requirements of w ater quality improv ement and to tal amo unt co ntr ol of po llutants in the basin, and effect ively reduces capital input. It can pr ovide a reference for w ater environment management and sustainable dev elo pment of river basins.
