摘要:
针对城镇污水处理厂提标改造出水水质要求高、无新增用地等难点，采用3种基于泥膜耦合的强化生物处理工艺，以实际城镇污水为处理对象进行中试研究。3种工艺分别是以芽孢杆菌为优势菌的生物反应器（BBR工艺）、高浓度复合粉末载体生物流化床（HPB工艺）和移动床生物膜反应器（MBBR工艺）。与厂区出水水质进行同步比较，结果表明，3种工艺出水TN平均浓度比厂区二沉池出水降低39%~57%，在不投加药剂情况下出水TP浓度与厂区投加药剂情况下相当。3种强化生物处理工艺经驯化后，污泥中菌群多样性低于厂区活性污泥，门水平上富集的微生物菌群主要为变形菌门（Proteobacteria）和厚壁菌门（Firmicutes），属水平上富集的聚磷菌和兼性厌氧菌平均相对丰度比厂区活性污泥分别提高了0.94%和29.76%，强化了脱氮除磷效果。
Abstract:
In response to the challenges of stringent effluent quality requirements and the lack of available land for upgrading wastewater treatment plants (WWTPs), three enhanced biological treatment processes based on sludge-biofilm coupling were selected for pilot-scale studies using actual municipal wastewater treatment scenarios. These processes included the biological reactor with Bacillus as the dominant bacteria (BBR process), the high-concentration composite powdered carrier biological fluidized bed (HPB process), and the moving bed biofilm reactor (MBBR process). The average total nitrogen (TN) in the effluent from the three processes was 39% to 57% lower compared to that in the effluent from secondary sedimentation tank of the WWTP. Additionally, the total phosphorus (TP) in the effluent without chemicals addition was comparable to that of the effluent from the WWTP with chemicals addition. After the acclimation of the three enhanced biological processes, the microbial diversity in the sludge was found to be lower than that in the activated sludge of the WWTP. At the phylum level, the enriched microbial communities were predominantly composed of Proteobacteria and Firmicutes. At the genus level, the average relative abundance of phosphate-accumulating bacteria and facultative anaerobic bacteria increased by 0.94% and 29.76%, respectively, compared to the activated sludge in the WWTP. These changes contributed to an enhanced nitrogen and phosphorus removal efficiency.
