- Abstract
Untreated black water is harmful to the environment due to its contents of large amounts of organic compounds, ammonia (NH4+-N) and pathogenic bacterium. The combined ABR-MFC-MEC (anaerobic baffle reactor-microbial fuel cell-microbial electrolysis cell) process was developed in this study to treat black water without external input of energy or oxygen. The degradation features of carbonaceous matter and nitrogen pollutants in black water were investigated using the combined ABRMFC- MEC process in this study. Chemical oxygen demand (COD) and NH4+-N removal rates of the study process were over 92% and 50%, respectively, when feeding an influent (black water) with COD concentration of 1,500 ± 100 mg L–1 and NH4+-N concentration of 60 ± 5 mg L–1, while maintaining the whole process hydraulic retention time as 24 h. Proteobacteria, Firmicutes and Acidobacteria were found to be the dominant electrogenesis flora supporting decarbonization and denitrification in the combined ABR-MFC-MEC process.
