摘要:
分析了厌氧膜生物反应器（AnMBR）与传统厌氧生物反应器（如UASB）处理养猪废水过程中的污染物去除特性、甲烷生成特征及微生物群落结构。结果显示，AnMBR对COD的去除率保持在80%~90%，而UASB仅为40%~60%。由于AnMBR的厌氧微生物产甲烷活性更强，故其甲烷产量（最大约为0.27 L/gCOD）较UASB的高。通过分析厌氧污泥中微生物群落结构发现，AnMBR污泥中富集了大量能去除难降解有机物的功能菌，还含有大量乙酸营养型和氢营养型产甲烷菌，有机物降解途径更丰富，甲烷生成途径更多样，进而保证了更高的甲烷产量。此外，AnMBR的能量回收效率高于UASB系统，表明AnMBR用于养殖废水处理不仅可高效去除污染物，还能强化能源回收。
Abstract:
The characteristics of pollutant removal, methane generation and microbial community composition of an anaerobic membrane bioreactor (AnMBR) and a traditional up-flow anaerobic sludge bed (UASB) in the treatment of swine wastewater were analyzed. The removal rate of COD in the AnMBR remained at 80%-90%, whereas that of UASB was merely 40%-60%. Owing to the higher methanogenic activity of anaerobic microorganisms, the methane yield of AnMBR (up to 0.27 L/gCOD) exceeded that of UASB. Through the analysis of the microbial community composition in anaerobic sludge, it was discovered that the AnMBR sludge was enriched with a considerable number of functional bacteria capable of removing refractory organic matters, and also contained a significant number of acetotrophic and hydrotrophic methanogenic bacteria. The degradation pathways of organic matters were more abundant, and the methanogenesis pathways were more diverse, thereby ensuring higher methane yield. Additionally, the energy recovery efficiency of the AnMBR was higher than that of the UASB system, suggesting that the AnMBR employed in livestock wastewater treatment not only effectively eliminated pollutants but also enhanced energy recovery.
