概括

测量呼吸计活动 (AT4) 为评估危险工业废物的生物降解性提供了一种可靠的方法. 这种方法克服了传统的BOD5/COD比率的局限性,改善了垃圾填埋场废物管理,减少了对环境的影响.

科学领域:

环境科学环境科学
废物管理废物管理
生物技术是生物技术.

背景情况:

垃圾填埋场生物稳定性对于管理环境影响和排放至关重要.
欧洲立法要求减少可生物降解废物,但缺乏明确的稳定性参数.
目前西班牙对液的方法 (BOD5/COD比率) 不足,导致虚假阴性.

研究的目的:

使用呼吸计活动 (AT4) 确定危险工业废物的生物降解性.
建立一种可靠的废物表征和废物处置前评估方法.
提高垃圾填埋场的可持续性,减少环境污染.

主要方法:

通过测量呼吸学活性 (AT4) 确定生物降解性.
评估了微生物注射剂和样本大小 (高达20g) 的影响.
与废物pH,BOD5/COD比率,挥发性物质含量和有机碳相关联的AT4值.

主要成果:

AT4测量独立于微生物注射剂丰富.
20g的样本大小被证明对敏感的生物降解性确定有效.
在pH值为6.510.5.5的废物中观察到最佳的呼吸学活性.
AT4值显示独立于传统的有机物参数 (BOD5/COD,挥发性含量,TOC,DOC).

结论:

AT4提供了对危险工业废物组成和稳定性的新见解.
将AT4纳入废物表征协议可以识别过度生物降解的废物.
这种方法提高了垃圾填埋场废物管理,防止排放和促进可持续性.

Bioremediation

Bioremediation

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.
