In this study, an anaerobic baffled reactor (ABR) with four compartments was employed to treat alkali-decrement wastewater of polyester fabrics under different organic loading rates. The stable operation of this reactor was achieved in 70 days at a hydraulic retention time of 36 h and mesophilic temperature of 35 ± 1 °C. It is found that the chemical oxygen demand removal and decolorization of this system can be as high as 79.0% and 87.7%, respectively. The different acidogenesis and methanogenesis in four compartments was acclimated by the variation of pH, oxidation reduction potential values and operational conditions in the spatial distribution of the first to fourth compartments of the ABR system. In addition, the dehydrogenase activity (DHA) and coenzyme F concentrations along the four compartments ranged from 67.8 to 185.21 μgTF/(gVSS·h) (TF: triphenyl formazan; VSS: volatile suspended solids) and 0.123 to 0.411 μmol/g, respectively. These results indicated that the ABR could separate acidogenesis and methanogenesis in longitudinal distribution and treat well the alkali-decrement wastewater.
在本研究中，采用具有四个隔室的厌氧折流板反应器（ABR）在不同有机负荷率下处理聚酯织物的碱减量废水。该反应器在水力停留时间为36 h、中温温度为35±1℃的条件下，70天内实现了稳定运行。结果发现，该系统的化学需氧量去除率和脱色率分别高达79.0%和87.7%。通过ABR系统第一至第四隔室空间分布中pH值、氧化还原电位值和运行条件的变化，使四个隔室中的不同产酸和产甲烷过程得到驯化。此外，沿四个隔室的脱氢酶活性（DHA）和辅酶F浓度分别为67.8至185.21μgTF/（gVSS·h）（TF：三苯基甲臜；VSS：挥发性悬浮固体）和0.123至0.411μmol/g。这些结果表明，ABR能够在纵向分布上分离产酸和产甲烷过程，并能很好地处理碱减量废水。
