Anaerobic digestion has historically shown critical operational limitations for treating industrial wastewater. Our work aims to evaluate the resilience capacity of a novel concept so-called microbial electrochemical fluidized bed reactor (ME-FBR) for treating real brewery wastewater under continuous operation mode over one year period. All assays were run in parallel using a conventional anaerobic fluidized bed reactor (AFBR). The resilience tests were designed attending to the most typical operational problems showed by the AFBR technology in real brewery wastewater treatment plants. Four different stress situations were tested: i) pollutants overloading (as high as 51.2 kgCOD/m³ d), ii) presence of an active biocide in the fed stream (5% V_biocide/V_reactor), iii) operation of the reactors after long starvation periods (16 days) and iv) operation at low temperature (<25 °C). Our pre-pilot scale ME-FBR outperformed traditional AFBR for wastewater treatment capacity under all stress test regarding COD removal rate, total nitrogen (TN) removal rate and bioenergy recovery (bioelectrochemical-assisted hydrogen generation). Among all stress test, low temperatures and long starvation periods deeply decrease the robustness of both technologies.

厌氧消化历来显示出处理工业废水的关键操作限制。我们的工作旨在评估一种新概念，即所谓的微生物电化学流化床反应器（ME-FBR）的回弹能力，该反应器在连续运行模式下处理一年以上的啤酒废水。所有测定均使用常规厌氧流化床反应器（AFBR）并行进行。弹性测试是针对AFBR技术在实际啤酒废水处理厂中表现出的最典型的操作问题而设计的。测试了四种不同的压力情况：i）污染物超载（高达51.2 kgCOD / m ³ d），ii）进料流中存在活性杀菌剂（5％V_杀菌剂/ V_反应器）），iii）长时间饥饿（16天）后运行反应器，iv）在低温（<25°C）下运行。在所有压力测试中，关于COD去除率，总氮（TN）去除率和生物能回收（生物电化学辅助制氢）的测试，我们的试点规模ME-FBR在废水处理能力方面均优于传统AFBR。在所有压力测试中，低温和长时间饥饿会大大降低这两种技术的耐用性。
