In order to explore whether the acidogenic phase and methanogenic phase could be separated vertically into a single-stage anaerobic reactor, a controlled double circulation (CDC) anaerobic reactor was proposed for treating traditional Chinese medicine (TCM) wastewater in this study. The results showed that most of the organic pollutants and refractory were removed in the first reaction area where most of the amount of sludge existed. The organic acids were accumulated in the first reaction area, and larger specific methanogenic activity (SMA) and coenzyme F values were found in the second reaction area. Bacterial and archaeal community structures in the two reaction areas of the CDC reactor were analyzed by Illumina MiSeq Sequencing, which revealed that the archaeal community showed larger difference compared with the bacterial community. Differences in the performance and microbial composition of the two reaction areas confirmed that phase separation was implemented in the CDC reactor.
为了探索产酸相和产甲烷相是否可以垂直分离到一个单级厌氧反应器中，本研究提出了一种控制双循环（CDC）厌氧反应器来处理中药废水。结果表明，在存在大部分污泥的第一反应区中去除了大部分有机污染物和难降解物质。有机酸在第一反应区中积累，第二反应区中发现更大的特定产甲烷活性（SMA）和辅酶 F 值。通过 Illumina MiSeq 测序分析了 CDC 反应器两个反应区的细菌和古菌群落结构，结果表明古菌群落与细菌群落相比表现出更大的差异。两个反应区性能和微生物组成的差异证实了在 CDC 反应器中实现了相分离。
