| 中文摘要 |
| 从技术经济角度对络合萃取法处理含酚废水进行了分析,建立了投资及净现值与处理量和浓度的关系式。结果表明：络合萃取法投资及净现值(不回收酚时)指标对处理量敏感,而对浓度不敏感；回收酚时净现值指标对处理量和浓度皆敏感,且存在一个盈亏平衡点,其临界浓度为1000mg/L,高于此浓度,络合萃取工艺处理为盈利项目。 |
| 英文摘要 |
| Included in this paper is an analysis from a point of view of technical economy for the phenolic wastewater treated by complexation extraction process.Some equations between investment or net present value (NPV) and water quantity and concentration are built.The results show that both index of investment and NPV are sensitive to the water quantity,but not the concentration for the complexation extraction process without phenol recovery;for the process with phenol recovery,NPV is sensitive to the water quantity and concentration and there is an equilibrium concentration of profit and loss of 1000mg/L,when the concentration is larger than 1000mg/L,the complexation extraction process becomes a profit project. |
