【摘要】：研究了聚合氯化铝(PACl)对序批式生物膜滤池(SBBF)处理生活污水的强化作用,包括去除效能的影响和基于454焦磷酸测序的微生物多样性分析.研究结果表明:PACl投加可使得SBBF获得满意的碳氮磷去除效果,同时高通量测序结果有助于认识铝盐对废水生物处理系统微生物的影响;50mg·L~(-1)的PACl投加可以使出水的总磷(TP)去除量从48.7%显著提高至68.2%,TP浓度低于0.5mg·L~(-1),对氮和化学需氧量(COD)去除的影响较小;454焦磷酸测序分析揭示铝胁迫下SBBF的微生物的多样性和丰度;铝盐投加可以使得浮游菌属(Planctomyces)、消化链球菌属(Peptostreptococcaceae)和嗜冷菌属(Psychrobacter)的丰度减少,假单胞菌属(Pseudomonas)和梭状芽孢杆菌属(Clostridium)的丰度增加,而不动杆菌属包括tjernbergiae不动杆菌(Acinetobacter tjernbergiae)和鲁菲不动杆菌(Acinetobacter lwoffii)一直处于主导地位.
[Abstract]:The enhancement effect of polyaluminum chloride (PACl) on the treatment of domestic sewage by sequencing batch biofiltration filter (SBBF) was studied, including the effect of removal efficiency and microbial diversity analysis based on 454 pyrosequencing. The results show that the addition of PACl can make SBBF obtain satisfactory removal efficiency of carbon, nitrogen and phosphorus. At the same time, the results of high throughput sequencing are helpful to understand the effect of aluminum salt on microorganism in wastewater biological treatment system, and the addition of PACl of 50mg L ~ (-1) can significantly increase the removal rate of total phosphorus (TP) from 48.7% to 68.2%. The concentration of TP is lower than that of 0.5mg L ~ (-1), and the nitrogen and chemical oxygen demand (COD) are lower than that of 0.5mg L ~ (-1). 454 pyrosequencing revealed the diversity and abundance of SBBF microorganism under aluminum stress. Addition of aluminum salt decreased the abundance of (Planctomyces), (Peptostreptococcaceae) and (Psychrobacter), and increased the abundance of (Pseudomonas) and (Clostridium). Acinetobacter including Acinetobacter tjernbergiae (Acinetobacter tjernbergiae) and Acinetobacter rufii (Acinetobacter lwoffii) have been dominant.
