【摘要】：研究了聚合氯化鋁(PACl)對序批式生物膜濾池(SBBF)處理生活污水的強化作用,包括去除效能的影響和基于454焦磷酸測序的微生物多樣性分析.研究結果表明:PACl投加可使得SBBF獲得滿意的碳氮磷去除效果,同時高通量測序結果有助于認識鋁鹽對廢水生物處理系統(tǒng)微生物的影響;50mg·L~(-1)的PACl投加可以使出水的總磷(TP)去除量從48.7%顯著提高至68.2%,TP濃度低于0.5mg·L~(-1),對氮和化學需氧量(COD)去除的影響較小;454焦磷酸測序分析揭示鋁脅迫下SBBF的微生物的多樣性和豐度;鋁鹽投加可以使得浮游菌屬(Planctomyces)、消化鏈球菌屬(Peptostreptococcaceae)和嗜冷菌屬(Psychrobacter)的豐度減少,假單胞菌屬(Pseudomonas)和梭狀芽孢桿菌屬(Clostridium)的豐度增加,而不動桿菌屬包括tjernbergiae不動桿菌(Acinetobacter tjernbergiae)和魯菲不動桿菌(Acinetobacter lwoffii)一直處于主導地位.
[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.
