利用升流式厌氧污泥床（UASB），以精对苯二甲酸（PTA）废水为降解对象，在中温条件（30℃）下研究PTA废水方式的启动和葡萄糖方式的启动及菌群结构变化。实验结果表明，葡萄糖启动方式和PTA废水启动方式均可成功启动UASB反应器，葡萄糖启动完成后COD去除率在75%左右，TA去除率约为65%；PTA废水启动完成后COD去除率在63%左右，TA去除率在53%左右。通过对比发现，葡萄糖启动方式更容易启动UASB反应器，且降解效率高。对葡萄糖启动方式过后的污泥进行微生物多样性分析发现，门类上，污泥样主要以Chloroflexi（绿弯菌门）、Proteobacteria（变形菌门）、Actinobacteria（放线菌门）和Bacteroidetes（拟杆菌门）为主；而在种属中，污泥样主要以norank＿f＿norank＿o＿SBR031、norank＿f＿Bacteroidetes＿vadinHA17、Propioniciclava、Anaerolineaceae、Syntrophus、Anaerolinea、Georgenia、Longilinea为主。

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.
