摘要
采用化学共沉淀法制备了生物炭负载纳米Fe_(3)O_(4)(Fe_(3)O_(4)@WB)材料,用于提高厌氧消化过程中电子传递效率进而加速活性红2(RR2)的降解。采用XRD、FTIR等检测方法证实了纳米Fe_(3)O_(4)已成功负载于生物炭。厌氧降解结果表明,Fe_(3)O_(4)@WB显著提高了对RR2废水的厌氧消化性能,与空白组相比,COD去除率、CH4产量和RR2的降解率分别提高了14.42%、42.64%和26.81%。同时,电子传递体系(ETS)活性、辅酶F420含量及污泥电导率的提高进一步证明了系统的电子传递得到增强。
Biochar-loaded nano-Fe_(3)O_(4)(Fe_(3)O_(4)@WB)has been prepared by the chemical co-precipitation method to improve electron transfer efficiency during reactive red 2(RR2)anaerobic digestion.XRD,FTIR confirmed that the nano-Fe_(3)O_(4) has been loaded on biochar successfully.The results of anaerobic digestion of RR2 indicated that Fe_(3)O_(4)@WB improved the anaerobic digestion obviously.Compared with the control reactor,the COD removal efficiency,methane production and degradation rate of RR2 were increased by 14.42%,42.64% and 26.81%,respectively.Moreover,the increase of electron transfer system(ETS)active,coenzyme F420 concentration and sludge conductivity confirmed the improvement of electron transfer efficiency.
