精确调控物质传递和电子转移，合理构建并有效利用多相微界面过程，是提高水处理效率的重要途径。然而，传统宏观尺度下的粗放式过程已远不能满足对水处理技术创新与变革的需求。如何通过微尺度下材料的精细设计，将污染物的转化和界面行为进行原理和过程融合，使电子、质子、活性物种等得到有效传递与合理利用，是水处理科技研究的前沿性方向。为此，本项目拟通过材料微观几何形貌设计和功能结构优化，以强化传质和电子转移为核心机制，构造一个高度凝缩的反应空间，优化其内部微流场和微电场的耦合作用，使氧化还原、吸附沉淀、材料再生、污染物资源化和能源化等过程在微场中协同实现；以微观设计-原理协同-过程调控-工艺构建为主线，重点突破微流场-微电场耦合的净水微系统构造原理，阐明微场中污染物的传质过程与转化机制，确定微场水处理优化条件与调控途径，创建由微场高度集成的宏观净水反应器与新工艺，推动水处理技术原理和工艺模式的颠覆性变革。

It is an important way to improve the efficiency of water treatment by accurately controlling the mass and the electron transfer, as well as the rational design and effective utilization of the solid/water interface. However, the traditional rude manipulation method failed to meet the growing needs for innovation and reform in water treatment technology. It is the research frontier of water science and technology that through tuning of the material characteristics in nano- to micro scale, coupling the transformation of pollutants and the interfacial physic-chemical processes, the electron, proton or active species can be utilized in effective way. Therefore, in this project, we will design and construct a cluster of micro reactors with enhanced mass and electron transfer through optimization the nanoscale geometry and functionality of the materials. In the micro reactor, the micro flow field and electric field will optimize the physic-chemical processes, such as redox conversion, adsorption and precipitation, regeneration, waste recovery and energy harvesting. The thread running through this project is to design materials in nanoscale, collaborate multi-processes, followed by online regulation and technology development. We will break through the coupling mechanism of micro flow field and micro electric field, elucidate the mass transfer and transformation of pollutants in the micro fields, clarify the optimization and regulation approaches for the micro field water treatment technology, establish water treatment system through highly integrated micro reactors and finally enable a disruptive innovation for water treatment technology.
