The Feasibility Study In Regradation Of Conlaminants In Water Of Technology Using Microbial Fuel Cell

This paper introduces the development of Microbial Fuel Cell (MFC), the latest research process and the focus of this area nowadays. For these reasons, microbial fuel cell (MFC) technique in this paper combining the advantages of the anaerobic metabolism and aerobic metabolism. It is not only improve the efficiency of bacterial metabolism, but also deal with high concentrations of toxic and harmful wastewater, and on that basis, it may supply power.We create a system of microbial fuel cell with two chambers, making the Ordinary organic glucose, toxic and harmful substances such as: phenol and bisphenol A, as well as landfill leachate and industrial cutting fluid wastewater as the matrix, treatment efficiency is comparied with conventional anaerobic digestion. And phenol as a characterized pollutant, discusses the effects of different temperature, substrate concentration, diameter of extended bridge and whether microbial inoculation on the microbial fuel cell treatment efficiency.The experiment results summarized as follows:1.When using glucose as a single fuel, MFC its degradation rate of 82%, was significantly higher than the conventional anaerobic digestion of 54% , and the MFC had a better performance in electricity product, with electricity production cycle more than 400h and the maximum output voltage up to 795mV.2.Under Closed-circuit, MFC state phenol degradation rate was increased by 26% compared with the open state; MFC and anaerobic reactor have different in the degradation of phenol at different temperatures: at 25℃, the efficiency is the highest and the removal rate reached 90%, notable thing is the removal rate at 15℃is the highest.3.At different organic loading, phenol removal efficiency of MFC enhanced by 30 % than conventional anaerobic digestion, with the organic load increasing, the removal rate of phenol reducing; the diameter of extended bridge more large, the removal rate of phenol more fast; compared the inoculation of microorganisms with non-inoculated, the later showed that removal rate of phenol is lower , just 20%.4.When treat bisphenol A, the removal rate of MFC can reach 53%, but conventional anaerobic digestion is less than 20%. 5.MFC on COD removal efficiency increased slightly 3 percentage points than conventional anaerobic digestion when treating the landfill leachate.6.Compared MFC with the conventional anaerobic digestion on the degradation of industrial cutting fluid about the COD variation, the removal rate are 72.7% and 68.7%, the final removal rate just higher 4 percent.The research results showed that the microbial fuel cell in dealing with toxic and harmful substances has a higher removal efficiency and electricity product; as a new way of sewage treatment, MFC improves the performance of dealing with a special wastewater; By integration with the anaerobic microbial treatment, microbial fuel cell can be integrated perfectly the advantages of anaerobic metabolism, So the further application of this technique would have a promising future.
