| 摘 要： | 对厌氧折流板反应器（ABR）处理精对苯二甲酸（IOTA）生产废水的启动及相分离过程进行研究。结果表明：经过62d的运行，反应器在（35±1）℃、水力停留时间40h、容积负荷3．60kg/（m3·d）的条件下，最大COD去除率达到80％以上，ABR启动成功。沿着水流方向，不同格室中挥发性脂肪酸（VFA）浓度依次减小，CH4含量不断增加，且污泥中挥发性悬浮固体浓度（VSS）及其与总悬浮固体浓度（弼）之比、产甲烷活性和辅酶F420不断增大，ABR中显示出显著的厌氧微生物相分离特性。

| Abstract: | The start-up and phase separation characteristics of the anaerobic baffled reactor （ABR） trea- ting purified terephthalic acid （PTA） wastewater were investigated. Results showed that under these con- ditions the temperature was （35±1 ）℃, hydraulic retention time was 40 h and volumetric loading rate was 3.60 kg/（m3·d） , the ABR started up successfully and the maximum removal efficiency of COD reached 80% after 62 d operation. The concentration of volatile fatty acids （VFA） in the different com- partments of ABR decreased along the flow direction, In contrast, the content of CH4, the volatile sus- pended solid （VSS）, the ratio of VSS and the total suspended solid （TSS）, the specific methane pro- duction activities and the coenzyme F420 increased, the significant phase separation characteristics. |
