概括

污泥处理床有效地去除大多数微污染物,但仍保留一些持久性化合物. 对于安全的污泥再利用和了解长期生态影响,需要进一步的研究.

科学领域:

环境科学
环境工程
废水处理

背景情况:

污泥处理床 (STRB) 提供可持续的污水污泥管理.
STRB中的微污染物的命运和由此产生的生物固体的质量尚未完全理解.
评估微污染物去除对于安全利用生物固体作为肥料至关重要.

研究的目的:

在试点规模的STRB中研究49种有机微污染物的去除效率.
评估三种通风模式 (主动,被动,非通风) 对微污染物命运的影响.
识别持久或累积的微污染物并评估它们对环境的风险.

主要方法:

试验规模的STRB种植 Miscanthus x giganteus 经营了16个月.
污泥每40天一次以16公斤干物质/米2加载,料污泥含量为0.2%的DM和78.3%的挥发性固体.
分析了25种精选的微污染物,重点是检测到超过检测限值的21种化合物.

主要成果:

在分析的25种微污染物中,21种显示出高达99%的去除率,不论是空气化类型.
甲化物 (BAC),卡巴马西平和醇显示持久性或积累.
一项初步的风险评估表明,三甲和亚胺对土壤微生物的风险很高.

结论:

STRB显示出从污水污泥中去除微污染物的巨大潜力.
与其他环境因素相比,通风强度对大多数微污染物的去除似乎不那么重要.
持续性化合物及其生态风险需要进一步研究以确保污泥的安全再利用.

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.

Environmental Applications of Microorganisms

Environmental Applications of Microorganisms

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...
