- 摘要:
- 采用聚氧化丙烯三醇（PPT）改性聚乙烯醇（PVA）/海藻酸钠（SA）凝胶球固定化活性污泥，并考察有毒有机物和高盐度环境对固定化污泥的呼吸速率、微生物活性和微生物群落结构的影响。结果表明，改性后的凝胶球在维持分子结构稳定的同时，具有更大的比表面积、总孔容以及更小的平均孔径。当废水中含有苯酚、间甲酚、硫脲和NaCl时，固定化污泥的比呼吸速率（SOUR）、氨氧化速率（AUR）和污泥电子传递体系（ETS）活性均显著降低，且抑制程度与有毒有机物的浓度呈正相关关系。苯酚、间甲酚、硫脲和NaCl对ETS活性的半抑制浓度分别为435.22 mg/L、285.51 mg/L、12.71 mg/L和11.36 g/L。苯酚和间甲酚通过增加对酚类物质具有降解能力的厌氧菌属占比，而NaCl则通过提高耐盐菌属占比，显著改变了包埋污泥的微生物群落结构，并共同抑制了氨氧化菌（AOB）的活性。
- Abstract:
- Polyvinyl alcohol (PVA)/sodium alginate (SA) gel spheres modified with polypropylene triol (PPT) were employed for the immobilization of activated sludge. The impacts of toxic organic compounds and high salinity environment on the respiration rate, microbial activity, and microbial community structure of the immobilized sludge were systematically investigated. The modified gel spheres exhibited enhanced stability of the molecular structure, along with an increased specific surface area, greater total pore volume, and a reduced average pore diameter. When the wastewater contained phenol, m-cresol, thiourea, and NaCl, the specific oxygen uptake rate (SOUR), ammonia utilization rate (AUR), and the electron transport system (ETS) activity of the immobilized sludge were markedly decreased. The degree of inhibition was positively correlated with the concentration of toxic organic compounds. The half-inhibitory concentrations of phenol, m-cresol, thiourea, and NaCl on ETS activity were determined to be 435.22 mg/L, 285.51 mg/L, 12.71 mg/L, and 11.36 g/L, respectively. Phenol and m-cresol markedly influenced the microbial community structure of the embedded sludge by enhancing the abundance of anaerobic bacteria capable of degrading phenolic compounds. In contrast, NaCl significantly promoted the proliferation of salt-tolerant bacteria and concurrently suppressed the activity of ammonia-oxidizing bacteria (AOB).
