Two-Level Optimization Modeling for Water Waste Load Allocation(WLA) Based on the Principles of Efficiency and Equity 效率与公平两级优化的水污染物总量分配模型
On this basis, this article established the multi-level waste load allocation method and allocated total load respectively into the regions level and the enterprises level. 在此基础上建立了多层次污染物负荷分配方法,即分别在区域和排污单位两个层面进行总量的分配。
Nitrogen and phosphorous tend to be treated as conservative material in previous study and non-point pollution source is considered inadequately in waste load allocation. 以往的环境容量研究中常将氮磷等营养盐作为保守物质对待,而且非点源污染在污染负荷分配研究中亦考虑不足。
A case study shows that the optimal waste load allocation can achieve water quality standards in stochastic conditions, and the model's outcomes are clearly different from those of the conventional deterministic linear programming model. 研究结果表明,污染负荷优化分配结果能够满足随机条件下的水质达标率要求,并且与传统的确定性线性规划模型的分配结果相比有着明显差别。
But now there are still many problems on total water waste load allocation technology and the course of water pollutant control is being decelerated. 但从目前国内外水污染物总量分配技术现状来看,该技术尚存在种种问题,进而影响到水污染物总量控制的整体进程。
