| Abstract: | Based on the bio-electrochemical theory,vertical flow constructed wetland embedded with fuel cell new device was built to test the micro-polluted source water,examine the effect of water purification and electrical characteristics of biological products.The results show that: 1)when the external resistance is 6 000 Ω,the maximum output voltage achieved 777 mV,the maximum power density of 8.05 mW/m2.2)The system exhibited effective removal of COD,nitrates from wastewater,it has a strong ability in denitrogenation with the maximum removal efficiency of 97.35% and average removal efficiency of 70% when the influent average TN was 3.3 mg/L.3)It does not affect the normal growth of plants as well. |
| Keywords: | vertical flow constructed wetland microbial fuel cell micro-polluted source water denitrification power generation |
