| Abstract: | 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. |

| Keywords: | complexation extraction process phenolic wastewater technical economy investment net present value concentration of profit and loss critical concentration |
