Bioremediation

18.3K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

  • 生物修复工程 生物修复工程

背景情况:

  • 纸和造纸行业的废水含有高度的醇,增加了水体中的生物氧需求 (BOD) 和化学氧需求 (COD).
  • 化合物对环境构成重大风险,需要有效的处理策略.

研究的目的:

  • 从工业废水中分离和识别有效的降解细菌.
  • 开发和评估一种固定微生物联盟,用于处理高强度类废水.
  • 为了评估治疗后BOD和COD的减少.

主要方法:

  • 隔离和识别可降解的细菌 (Staphylococcus sp. 和 Staphylococcus sciuri) 使用 16S rRNA 测序.
  • 使用活性炭,木尘和煤灰,使细菌分离物和联合体不移.
  • 工业废水的处理使用生物过塔与动不动的细菌联盟在5毫升/分钟的流量.

主要成果:

  • 这种细菌分离了SP-4 (Staphylococcus sp.) 和SP-8 (Staphylococcus sciuri) 的降解醇度分别高达1600毫克/升和1800毫克/升.
  • 固定微生物联盟在废水中实现了99%的降解.
  • 在经过处理的废水中观察到BOD和COD的显著减少.

结论:

  • 固定微生物联盟,特别是在生物过塔中,对于废水的生物修复非常有效.
  • 开发的系统可以处理高度的醇 (高达1800毫克/升),适合实体工业应用.
  • 这种方法为管理废水污染提供了可持续的解决方案.
