The treatment of dye wastewater has always been an environmental problem of common concern in various countries. Its large amount and difficulty have always been the focus of environmental problems, which was difficult to solve. For the treatment of wastewater, there were usually precipitation method, redox method, biological method, etc. among them, the biological method was characterized with obvious effect and less secondary pollution. The combination of microorganism and nano materials was a new direction of wastewater treatment. In this study, through the comparison of decolorization rate between Shewanella oneidensis MR-1 and Shewanella oneidensis MR-1 with nano iron and the comprehensive analysis of specific CODcr and infrared spectrum, it was found that nano iron could significantly promote and strengthen the decolorization of Shewanella oneidensis MR-1 in the treatment of wastewater. The combined system had a good effect on 100 mg/L methyl orange, and the decolorization rate of methyl orange was 90.2% for 140 h, and the concentration of the treated methyl orange solution was 11.2 mg/L. Results found that the optimum treatment effect and the least amount of nano-iron in 24 h was the addition of 90 mg of nano-iron, which greatly saved time, and the decolorization rate was 96.8%, the concentration of methyl orange solution was 4.2 mg/L. Therefore, the synergy between nano materials and microorganisms may be a trend of efficient treatment in the future. [ABSTRACT FROM AUTHOR] |
