N2 - By means of an up-flow anaerobic sludge bed (UASB), with purified terephthalic acid (PTA) wastewater as the degradation object, the startup of PTA wastewater mode and glucose mode, and the changes of microflora structure are studied at medium temperature (30℃). Experimental results show that both the start-up modes can successfully start up UASB reactor. After glucose start-up, COD removal rate is around 75%, and TA removal rate is about 65%. After PTA wastewater startup, COD removal rate is 63%, and TA removal rate is 53%. It is found through comparison that glucose startup mode is easier to start UASB reactor, which will obtain higher degradation efficiency.It is found through analysis on microbial diversity of the sludge after glucose startup mode that microflora in the sludge samples contains mainly categories Chloroflexi, Proteobacteria, Actinobacteria and Bacteroidetes. Among the species, the sludge samples contain mainly norank-f-norank-o-SBR031, norank-f-Bacteroidetes-vadinHA17, Propioniciclava, Anaerolineaceae, Syntrophus, Anaerolinea, Georgenia, Longilinea.
