| 当solution温度较低为20°C时, solution 粘度较大, 扩散系数比较小, 所以膜通量相对较小. 随着solution温度的升高, MF和UF膜的水通量也相应增大. 当温度增加大28°C时, 藻液粘度更小, 同事膜孔舒张程度最大, 膜水通量也达到最大. 但是当温度从24°C增加到20°C时, MF膜水通量增加并不明显. 这可能是因为温度过高, 影响到小球藻正常的新城代谢, EPS随之增加, solution中蛋白质和核酸的成分也增加了. 这些物质吸附在膜表面, 导致水通量下降 |

”从24°C增加到20°C时“这个不对吧。翻译如下 When the solution temperature is 20°C, the viscosity is large and the diffusion coefficient is small, so the membrane flux is relatively small. With the temperature increases, the flux of the MF and UF membranes also increase. When the temperature increases to 28 °C, the fluid viscosity is smaller,simultaneously, the diastole of the membrane pore and the membrane flux reach the largest degree. But when the temperature increases from 24 °C to 20 °C, the membrane flux of the MF increases not obviously.It may be because of the too high temperature which influences normal metabolism of the chlorella and as a result EPS increases, protein and nucleic acid also increase. These substances absorb on the membrane surface, leading to the water flux decreasing. |
