五价钒（V（Ⅴ））具有较强的毒性，在环境中广泛存在。本文采用双室微生物燃料电池，以人工模拟的含钒废水作为阴极电子受体，实现了 V（Ⅴ）的同步还原与产电。同时发现：较高的初始 V（Ⅴ）质量浓度能够提高微生物燃料电池的输出功率密度，但不利于 V（Ⅴ）的去除；降低 pH 对功率密度和 V（Ⅴ）的去除率都有利，但当 pH 低至2时，再减小 pH，上述两指标没有显著提高。V（Ⅴ）在微生物燃料电池中被还原为 V（Ⅳ），后者可以通过调整 pH 而沉淀，从而实现了含钒废水的有效处理并回收电能与钒元素。

Vanadium (V(Ⅴ))with strong toxicity is widespread in the environment.In this work,simutaneous reduction and e-lectricity generation in double chamber microbial fuel cell(MFC)was realized by using simulated wastewater containing vanadium (V)as cathode electron acceptor.The effects of the influent V(Ⅴ)concentration and pH on the performance of electricity pro-duction and removal efficiency of V(Ⅴ)were also studied.The higher mass concentration of V(Ⅴ)can improve the output power density,but it is not conducive to the removal of V(Ⅴ).The decrease of pH value improves the performance of MFC,but when the pH value is as low as 2,the maximum power density of MFC and V(Ⅴ)removal rate dose not significantly increase when further decreasing pH.V(Ⅴ)is reduced to V(Ⅳ)in the MFCs,while the latter can be precipitated by adjusting the pH vlaue, realizing the effective treatment of vanadium containing wastewater with energy and vanadium recovery.
