基于数据包络分析(DEA)的电镀废水处理方案选取

The selection of electroplating wastewater treatment schemes based on data envelopment analysis(DEA)

本文采用数据包络分析(DEA)方法研究电镀废水污水处理方案选取问题。对于电镀废水处理方案,采用非阿基米德无穷小量的C2R对偶输入模型,进行Matlab编程计算。计算结果表明四种方案的绩效排序为减压蒸发法>次氯酸钠法>离子交换法>电解法。故该厂采用减压蒸发法治理电镀废水的方案最适宜。

In this paper, data envelopment analysis(DEA) method is used to study the selection of electroplating wastewater treatment scheme. For electroplating wastewater treatment schemes,, the use of non-Archimedes infinite small amount of C2R dual input model, Matlab programming calculation. The results show that the performance of the four schemes is ranked as reduced pressure evaporation > sodium hypochlorite > ion exchange > electrolysis method. Thus, it is the most suitable plan to treat electroplating wastewater by vacuum evaporation in this factory.
