摘　　要：沉水植物-沉积型微生物燃料电池(Submerged plantsediment microbialfuelcell,SP-SMFC)是目前解决修复水体复黑臭最有发展前景的技术之一。以黑臭水体底泥为底质,构建了3种不同的沉水植物与沉积型微生物燃料电池耦合系统:分别为篦齿眼子菜-沉积型微生物燃料电池(标记为SP-SMFC1)、矮生苦草-沉积型微生物燃料电池(标记为SP-SMFC2)和金鱼藻-沉积型微生物燃料电池(标记为SP-SMFC3),为对照还构建了无植物的对照组(标记为SMFC)。结果表明:所构建的实验系统经驯化后能够稳定运行;引入沉水植物可提高系统输出电压,其中SP-SMFC2系统平均最高输出电压最大为0.659V;各实验组对底泥和上覆水的有机质和氮磷去除效果明显;构筑的系统可以有效防止水体复黑臭的发生。Submerged plant sediment microbial fuel cell(SP-SMFC)is one of the most promising technologies to solve the problem of restoring black odor water.Taking the black and odorous water sediment as the substrate,three different coupling systems of submerged plants and SMFC were constructed.They were divided into three types:SMFC plant stuckenia pectinata(labeled SP-SMFC1),SMFC plant dwarf bitter grass(labeled SP-SMFC2)and SMFC plant hornwort(labeled SP-SMFC3).A plant-free control group(labeled SMFC)was constructed as the control group.The results show that the constructed experimental system can run stably after domestication.The introduction of submerged plants can increase the output voltage of the system.And the maximum average output voltage of SP-SMFC2 system was 0.659 V.The removal of organic matter and nitrogen and phosphorus from sediment and overlying water was effective in all experimental groups.The system can effectively prevent the occurrence of black odor in water.
