摘要:
采用中试规模外部浸没式厌氧膜生物反应器(Anaerobic membrane bioreactor, AnMBR)处理实际养猪废水,考察了在不同水力停留时间(Hydraulic retention time, tHR)污泥质量浓度和沉降性能的变化以及对污染物的去除效果,分析了细菌和古菌群落结构的变化。结果表明,混合液悬浮固体(MLSS)质量浓度与混合液挥发性悬浮固体(MLVSS)质量浓度均呈现逐步上升趋势,MLVSS与MLSS质量浓度的比值保持在0.40～0.85。在tHR为5 d时,总化学需氧量去除率达80%±6%,溶解性化学需氧量占总化学需氧量去除率的55%,AnMBR对NH+4-N和总磷的去除效果不明显。古菌中甲烷囊菌在AnMBR启动调试期占优势,甲烷丝菌和甲烷螺菌在运行稳定期占优势,而调试运行期的优势菌种主要有草螺菌和嗜糖假单胞菌属,总体而言,运行稳定期的细菌总数和群落多样性均高于启动调试期。
Abstract:
A pilot-scale external submerged anaerobic membrane bioreactor(AnMBR)was used to treat actual swine wastewater, and the changes in sludge mass concentration and settling performance as well as its pollutant removal effect at different hydraulic retention times(tHR)were investigated, and the changes in the community structure of bacteria and archaea were analyzed. The result showed that the mass concentration of mixed liquor suspended solids ρ(MLSS)and the mass concentration of mixed liquor volatile suspended solids ρ(MLVSS)showed a gradual increasing trend, and the ratio of ρ(MLVSS)to ρ(MLSS)kept at 0.40—0.85. When tHR was 5 d, the removal rate of total chemical oxygen demand reached 80%±6%, and the dissolved chemical oxygen demand accounted for 55% of the total chemical oxygen demand removal rate; the removal of NH+4-N and total phosphorus by AnMBR was not significant. Among the archaea, methanobacterium dominated in the AnMBR startup and commissioning phase, methanosarcina and methanospirillum dominated in the operation and stabilization phase, whereas the dominant species in the commissioning and operation phase mainly consisted of clostridium and pseudomonas. The total number of bacteria and the diversity of communities in the operation and stabilization phase were higher than those in the startup and commissioning phase.
