Abstract
Domestication of aerobic activated sludge using for washing / bleaching effluent in the presence of Fe3 +was studied. Firstly,the optimal dosage of Fe3+ was determined as 30 mg / L by the experiment of effect of Fe3+ on microbial growth curve. Then,the aerobic activated sludge in the reactor was domesticated by washing / bleaching effluent with Fe3+ dosage of 30 mg / L,another reactor without Fe3+ was as control. In the entire process of domestication,COD and UV-254 removal efficiencies of the effluent with iron ion were higher than that of the control sample,and COD removal efficiencies of the two effluents were 78. 2% and 76. 0%,UV-254 removal efficiencies were 50. 0% and 37. 7% respectively at the end of domestication. The analysis of the dehydrogenase activity in the reactor with iron ions was higher than that of the control reactor.
