To investigate the removal effect of pollutants in mariculture sediment by sediment microbial fuel cell (SMFC) and its power generation capacity, the effects of external resistance, cathode pH and cathode dissolved oxygen concentration (DO) on the SMFC system were investigated. The results showed that the optimal parameters for SMFC were as follows: external resistance = 1500 Ω, pH = 8.5 and DO = 5 mg·L-1. In these situations, the power generation performance and organic degradation effect were both the best. The maximum output voltages were 585, 606, and 587 mV, respectively; the removal rates of COD in sediment were 75.51%, 84.21% and 86.63%, respectively; and the removal rates of ammonia nitrogen in sediment were 80.34%, 98.91% and 90.24%, respectively. The SMFC system had a certain degradation ability to pollutants such as COD and ammonia nitrogen in the sediment of the marine aquaculture areas, which had a broad application prospect.

In order to study the effect of nitrite and nitrate on the performance of microbial fuel cell, a system combining an anaerobic fluidized bed (AFB) and a microbial fuel cell (MFC) was employed for high-strength nitrogen-containing synthetic wastewater treatment. Before this study, the AFB-MFC had been used to treat high-strength organic wastewater for about one year in a continuous flow mode. The results showed that when the concentrations of nitrite nitrogen and nitrate nitrogen were increased from 1700 mg/L to 4045 mg/L and 545 mg/L to 1427 mg/L, respectively, the nitrite nitrogen and nitrate nitrogen removal efficiencies were both above 99%; the COD removal efficiency went up from 60.00% to 88.95%; the voltage was about 375 ± 15 mV while the power density was at 70 ± 5 mW/m2. However, when the concentrations of nitrite nitrogen and nitrate nitrogen were above 4045 mg/L and 1427 mg/L, respectively, the removal of nitrite nitrogen, nitrate nitrogen, COD, voltage, and power density were decreased to be 86%, 88%, 77%, 180 mV, and 17 mW/m2 when nitrite nitrogen and nitrate nitrogen were increased to 4265 mg/L and 1661 mg/L. In addition, the composition of biogas generated in the anode chamber was analyzed by a gas chromatograph. Nitrogen gas, methane, and carbon dioxide were obtained. The results indicated that denitrification happened in anode chamber.

The electrode material has the very important influence to the microbial fuel cell. The different electrode materials were studied for producing the electricity performance to MFC by the activated sludge as the substrate. The results indicated that the anode of graphite pole was 0.63 mW/cm2 of the area power density. The carbon paper was 60 (0.50mW/cm2). Carbon paper 90 was 0.23mW/cm2. Although having the biggest area power density, the general trend of the graphite pole is much lower than others and production of the electricity was not good. Even though the maximum of area power density of graphite pole, it might be the reason for increasing nutritive compound and elevation of temperature. The carbon paper 90 produce the area power density is the steadiest among three poles and its output voltage is a quite stable and low. MFC is excellent under carbon paper 90. The area power density had strong fluctuating scope, the power density is big and the overall value is high under carbon paper 60.

Recently, various steps have been taken to utilize and develop renewable and sustainable form of energies due to the negative impact and dire limitation over continuous dependency on fossil fuel. This paper presents the effects of aluminium mesh on the performance of a MFC. Aluminium mesh with rectangular shape was used as the electrode and experiments were conducted with respect to various types of resistors. The amount of voltages and power density generated were determined. It was found that the increase in bacterial activities resulted in the increment of oxygen supply, therefore, the voltage generated also increased. In addition, the longevity of bacterial activity is dependent on the amount of catalyst. Moreover, it was observed that the performance of aluminium mesh electrode was smaller than that of graphite electrode.
