摘　　要：通过构建人工湿地耦合微生物燃料电池(CW-MFC)工艺,在不同进水COD和水力停留时间(HRT)条件下,对CW-MFC耦合工艺产电性能及处理常规污染物进行了研究。结果表明:随着进水COD由50 mg/L提高到450 mg/L,系统稳定时输出电压先增大后减小,并在COD为350 mg/L时,输出电压达到最大为646 mV(外电阻为1000Ω);在低COD(50~150 mg/L)进水条件下,CW-MFC比CW系统的COD去除率要高;在HRT由36 h逐渐减小到12 h的过程中,HRT为30 h,实验组COD、NH_(4)^(+)的去除率达到最大,分别为95.7%、54.9%,与空白组相比NH_(4)^(+)的去除率差别不大,COD去除率高1.24%左右;在HRT为18 h时,CW-MFC系统的产电效果最好,最大功率密度为286.7 mW/m^(3)。Through builded constructed wetland coupled with microbial fuel cell system(CW-MFC),studied about CW-MFC electricity production and deal with conventional pollutants under different COD concentration and hydraulic retention time.The results showed that:With the increased of COD concentration from 50 mg/L to 450 mg/L,the output voltage increased initial and decreased gradually when the system is steady,also when COD is 350 mg/L,the maximum output voltage reaches 646 mV(the external resistance is 1000Ω).Under the conditions of low COD(50~150 mg/L)influent,the COD removal efficiency of CW-MFC is 10%higher than that of the CW system.;When HRT decreased from 36 h to 12 h,when HRT was 30 h,the removal efficiency of COD and NH_(3)-N in the experimental group reached the maximum,95.7%and 54.9%.Compared with the blank group,the removal efficiency of ammonia nitrogen was not very different,and the COD removal rate was 1.24%.When HRT was 18 h,the CW-MFC system had the best power generation effect and the maximum power density was 286.7 mW/m^(3).
