The interest in research on up-flow anaerobic sludge blanket (UASB) reactors is growing. The meta-analysis of bibliometric data highlighted the growing interest in four diverse topics: (i) energy recovery production; (ii) combination with other treatments; (iii) the study of processes for the removal of specific pollutants and, (iv) characterization of microbial community and granular sludge composition. In particular, the papers published in the first 6 months of 2021 on this process were selected and critically reviewed to highlight and discuss the results, the gaps in the literature and possible ideas for future research. Although the state of research on UASB is to be considered advanced, there are still several points that will be developed in future research such as the consolidation of the results obtained on a semi-industrial or real scale, the use of real matrices instead of synthetic ones and a more in-depth study of the effect of substances such as antibiotics on the microbiota and microbiome of UASB granular biomass. To date, few and conflicting data about the environmental footprint of UASB are available and therefore other studies on this topic are strongly suggested.
人们对上流式厌氧污泥床（UASB）反应器的研究兴趣日益浓厚。文献计量学数据的荟萃分析突出了人们对四个不同主题的日益关注：（i）能源回收生产；（ii）与其他处理方法的结合；（iii）去除特定污染物的工艺研究，以及（iv）微生物群落和颗粒污泥组成的特性。特别是，选择并批判性地回顾了 2021 年前 6 个月发表的关于该工艺的论文，以突出和讨论结果、文献中的差距以及未来研究的可能思路。尽管 UASB 的研究现状被认为是先进的，但仍有几个方面将在未来的研究中得到发展，例如在半工业或实际规模上巩固所获得的结果，使用真实基质而不是合成基质，以及更深入地研究抗生素等物质对 UASB 颗粒生物量的微生物群和微生物组的影响。迄今为止，关于 UASB 的环境足迹的可用数据很少且相互矛盾，因此强烈建议对此主题进行其他研究。
