摘要： 以城市富营养化严重的湖泊沉积物为底质，及总磷浓度0.2 mg/L的上覆水组成的P-SMFC系统，针对P-SMFC系统产电性能、磷形态转化特征与磷去除效率如何为植物黑藻所影响进行了研究，试验结果表明：经240 h，SMFC系统电压达到68.5 mV且稳定，启动成功。有无植物的P-SMFC系统输出电压分别为69、50 mV；电流密度、功率密度分别为52.56 mA/m2、3.92 mW/m2；42.40 mA/m2、2.54 mW/m2；有植物的P-SMFC系统对水中总磷、沉积物中全磷、有机质的累积去除率分别为76.5%、38.75%、82.89%、均高于无植物的SMFC系统的42.5%、29.17%、77.78%；表明植物的加入对于SMFC系统的产电过程有促进作用并且能大大提高磷去除率，但对提高有机质去除效能的能力有限；并且通过对磷元素形态变化研究证实植物的加入能促进有机磷矿化，无植物试验组中钙磷、铝磷、铁磷含量均少于有植物试验组。

Abstract: The P-SMFC system was constructed with the lake sediment with serious eutrophication as the bottom material and the overlying water with TP concentration of 0.2 mg/L. The effects of plant black algae on the phosphorus removal efficiency, the transformation characteristics of phosphorus form and the power generation performance in the P-SMFC system were investigated. The test results show that: after 240 hours, the voltage of the SMFC system reaches 68.5 mV and is stable, which starts successfully. The output voltage of P-SMFC system with and without plants are 69mV and 50 mV respectively, the current and power density are 52.56 mA/m2 and 3.92 mW/m2, 42.40 mA/m2 and 2.54 mW/m2 respectively; the cumulative removal rates of total phosphorus, total phosphorus in sediment and organic matter in P-SMFC system with plants are 76.5%, 38.75% and 82.89%, respectively, which are 42.5%, 29.17% and 77.78% higher than of those of SMFC system without plants. It is indicated that the addition of plants promotes the power generation process and greatly improves the phosphorus removal efficiency, but the ability to improve the organic matter removal efficiency is limited. Through studying the change of phosphorus form, it is proved that the addition of plants promotes the mineralization of organic phosphorus, and the contents of Ca-P, Al-P and Fe-P in P-SMFC system with plants are higher those in P-SMFC system without plants.
