%X The results were reported from a study on the treatment of dye-stuff wastewater by using an anaerobic/aerobic process,wherein the anaerobic stage was carried out in a UASB reactor and the aerobic sarge was using a conventional activated sludge process.The results show that with a raw dye-stuff wastewater of 1150-1300 mg COD/L and 500 fold colourity(a colour scale meant by the number of dilution times leading to a colour that seems to be the colour of tap water) under the condition of HRT 6-10h at the anaerobic stage,the COD removal was more than 60% and the colourity was reduced to 50-100 folds.If followed by an additional 6h aeration treatment,the total COD removal was up to 85%-90% and the colourity was further reduced to about 20 folds. The spectrometric analyses of influent and effluent revealed that the decolouration of dye-stuff wastewater mainly took place at the anaerobic stage and was achieved through bilogical degradation.It was concluded that the anaerobic/aerobic process was a cost-eff ective way to treat a dye-stuff wastewater and was of a great value of practical application.
