Effects of Synthetic Goethite on Anaerobic Degradation of Dye Wastewater

摘要

The effects of synthetic goethite on anaerobic degradation process of dye wastewater were investigated.Alphazurine A was used as the dye to manipulate the dye wastewater.The results showed that dye degradation was slightly inhibited by adding mineral material compared with the control group in the absence of external minerals.While adding synthetic goethite only when the logarithmic growth phase of the sludge can accelerate the anaerobic bleaching of Alphazurine A.Mineral material can promote the anaerobic bleaching of the dye,which can be partly attributed to the high electrical conductivity of mineral.
