人工湿地（CW）与微生物太阳能电池(MSC)可通过湿地植物、微生物、基质、电极的有机融合实现一体化，形成CW-MSC耦合系统。该系统利用湿地植物光合作用可直接转化太阳能为电能，在污水净化同时回收电能，将成为分散式持续可再生能源发电的一种新模式，具有良好的发展前景。在IVCW-MSC中，IVCW的下行池和上行池分别用作阳极区和阴极区，阳极区种植物，阴极区域不种植物,该结构有助于利用植物根系分泌有机物产电并且提高硝酸盐去除率。由于阳极区域的植物根系分泌沉积物与释放氧分别是产生电子和消耗电子的过程，本研究以植物为着手点，研究植物根系泌氧及分泌沉积物对于耦合系统产电与净化的作用与贡献，以及产电过程中湿地植物的生理生态响应。得到这两个过程对耦合系产电性能的量化模型，探寻长期产电过程中湿地植物的耐受性与生理响应机制，形成水质要求和产电性能多目标的植物选配方式，为IVCW-MSC长效运行提供理论支持。

The constructed wetland and microbial solar cell could be combined to form a new coupling system by the corporate process of wetland plant，microbe，substrate and electrode. This coupling system is able to directly transfer solar energy to electrical energy through the macrophytes photosynthesis, simultaneously purify wastewater and generate electrical energy. The coupling system would become a new mode for distributed and sustainable renewable energy generation and get a good prospect. In the IVCW-MSC, the down-flow chamber and up-flow chamber are able to be used for anode area and cathode area respectively. And in the anode the macrophytes are planted, while no plants in the cathode. Such structure is helpful for utilizing the rhizhodeposits to generate electric and improving the removal of the nitrate in the cathode. The rhizhodeposits in the anode could generate electron by the Electro-chemically active bacteria. The Root Oxygen Loss would consume the electron. Such two contrary process would be focused on and researched in order to discovery the effects and contribution on the electrical generation. Furthermore, the plant physio-ecology response on the pressure of electric current and voltage also should be investigated. By the two aspects of research, it is expected to obtain a quantitative model to predict the power output, to seek the physio-ecology response mechanism during the long-term electrical generation and to form the method of plant choice in different effluent and electrical generation, which could provide theoretical support for the long time operation of IVCW-MSC.
