概括
在单个生物反应器中成功开发了序列化/混合化 (SNMD). 石载体影响了微生物群落,但并没有影响该新型废水处理过程的整体处理性能.
科学领域:
- 环境工程
- 微生物学
- 废水处理
背景情况:
- 单个生物反应器中的序列化/混合化 (SNMD) 是一个研究不足的领域.
- 传统的废水处理通常涉及多个阶段,增加复杂性和成本.
研究的目的:
- 在单个生物反应器配置中适应SNMD的工业注射器.
- 为了比较传统的测序批量反应器 (SBR) 与化石载体SBR (SBBR) 的SNMD性能.
- 评估硫化物添加对SNMD过程的影响.
主要方法:
- 在SBR和SBBR系统中对276天的工业注射剂进行调整.
- 阶段性方法:SNHD适应,增加TAN负载,并添加硫化物SNMD.
- 检测TAN去除,酸盐和酸盐减少的性能.
主要成果:
- 在SNHD条件下,SBR和SBBR都实现了99%以上的TAN去除和完全的酸盐减少.
- 硫化物添加最初导致化物积累,但在90天内恢复了脱.
- 在SNMD条件下,平均TAN去除率为SBR的93. 4%和SBBR的90. 0% (p > 0. 05).
- 石载体影响了微生物群体的组成,特别是在硫化物驱动的条件下,但没有显著影响整体治疗性能.
结论:
- 在单个生物反应器配置中,SNMD过程是可行的,有或没有焦化载体.
- 在SNMD过程中,石载体主要影响微生物群体结构,而不是整体处理效率.
- 这项研究证明了一种可行的单反应器方法来进行先进的除.

Metabolism of Chemolithotrophs
167
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

Environmental Applications of Microorganisms
233
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Inorganic Nitrogen Assimilation
104
Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme...
