摘　　要：人工湿地(CW)处理鱼塘养殖废水存在处理效率低、稳定性差等问题。本研究采用电活性菌藻生物膜(BA)以微生物燃料电池(MFC)形式强化CW处理鱼塘养殖废水,即BA-MFC-CW。与CW组相比,BA-MFC-CW组对COD、总磷、总氮的去除率分别提高了26.69%、23.17%、16.67%。相比MFC-CW组,BA-MFC-CW组对COD、总磷、总氮去除率分别提高了0.95%、25.64%、6.48%。高通量测序表明,在电活性菌藻生物膜中,Acinetobacter、Cyanobium、Pseudomonas和Ottowia得到富集;在MFC阳极上,Geobacter、Aminicenantales和Clostridium生长状况良好。以上结果表明,电活性菌藻生物膜技术能够有效提高人工湿地处理水产养殖废水的效果。The treatment of fish pond wastewater by constructed wetland(CW) has some problems, such as low efficiency and poor stability. In this study, electroactive bacteria-algae biofilm(BA) was used to enhance CW treatment of fish pond aquaculture wastewater by the form of the microbial fuel cell(MFC), namely(BA-MFC-CW). Compared with the CW group, the removal efficiencies of COD, total phosphorus, and total nitrogen in the BA-MFC-CW group were increased by 26.69%, 23.17%, and 16.67%, respectively. Compared with the MFC-CW group, the removal efficiencies of COD, total phosphorus, and total nitrogen in the BA-MFC-CW group were increased by 0.95%, 25.64%, and 6.48%, respectively. High-throughput sequencing showed that Acinetobacter, Cyanobium, Pseudomonas, and Ottowia were enriched in the electroactive bacteria-algae biofilm. Geobacter,Aminicenantales, and Clostridium grow well on the MFC anodes. These results indicated that the electroactive bacteria-algae biofilm technology can effectively improve the effect of CW on aquaculture wastewater treatment.
