生物电化学技术在水生态修复中具有良好的应用前景。3种不同生境条件下的湖泊沉积物,经过30 d的电化学氧化后,只观测到1种沉积物中细菌微生物的Shannon指数发生了显著性改变(P0.05)。3种沉积物中共计17个细菌门的相对丰度发生显著性变化:其中只有酸杆菌门、硝化菌门和螺旋菌门的相对丰度大于1%。相反地,相对丰度最高的9个细菌门在电化学氧化组和对照组中的变化则不显著。电化学氧化对沉积物中不同细菌微生物之间的相互关系影响同样较小。但是,在纲分类水平上,电化学氧化对脱卤球菌纲和多种硫酸盐还原菌(如Thermodesulfovibrionia和Desulfobulbia)的相对丰度影响显著,表明电化学氧化可能改变沉积物中卤素和硫等元素的生物地球化学循环过程。研究成果为明确电化学氧化修复处理污染沉积物所造成的潜在生态效应提供了供更多理论依据。
