Performance assessment of membrane bioreactor (MBR) technology for the treatability of high-strength landfill leachate is relatively limited or lacking. This study examines the feasibility of treating high-strength landfill leachate using a hollow-fiber MBR. For this purpose, a laboratory-scale MBR was constructed and operated to treat leachate with a chemical oxygen demand (COD) of 9000-11,000 mg/l, a 5-day biochemical oxygen demand (BOD5) of 4000-6,000 mg/l, volatile suspended solids (VSS) of 300-500 mg/l, total nitrogen (TN) of 2000-6000 mg/l, and an ammonia-nitrogen (NH3-N) of 1800-4000 mg/l. VSS was used with the BOD and COD data to simulate the biological activity in the activated sludge. Removal efficiencies > 95-99% for BOD5, VSS, TN and NH3-N were attained. The coupled experimental and simulation results contribute in filling a gap in managing high-strength landfill leachate and providing guidelines for corresponding MBR application.
膜生物反应器（MBR）技术处理高强度垃圾渗滤液的性能评估相对有限或缺乏。本研究考察了使用中空纤维 MBR 处理高强度垃圾渗滤液的可行性。为此，构建并运行了一个实验室规模的 MBR，以处理 COD 为 9000-11000mg/L、BOD5 为 4000-6000mg/L、VSS 为 300-500mg/L、TN 为 2000-6000mg/L 和 NH3-N 为 1800-4000mg/L 的渗滤液。使用 BOD 和 COD 数据结合 VSS 模拟了活性污泥中的生物活性。BOD5、VSS、TN 和 NH3-N 的去除效率>95-99%。实验和模拟结果为管理高强度垃圾渗滤液提供了指导，填补了这方面的空白，并为相应的 MBR 应用提供了依据。
