概括
一种新的生物标志物方法准确量化了废水稀释,改善了废水处理设施 (WWTW) 的管理,并使基于废水的流行病学 (WBE) 能够为人口健康洞察提供成本效益.
科学领域:
- 环境科学 环境科学
- 环境工程 环境工程
- 公共卫生 公共卫生
背景情况:
- 废水处理厂 (WWTW) 的管理依赖于准确的流量数据.
- 在下水道中的稀释受雨水流入和透 (RDII) 的影响,使准确的负载估计变得复杂.
- 基于废水的流行病学 (WBE) 需要有关人口健康和环境相互作用的可靠数据.
研究的目的:

- 提高WWTW的运营效率和环境管理.
- 为WBE提供一个具有成本效益的工具.
主要方法:
- 测量了废水质量的关键参数:氨-N,正酸盐和crAssphage.
- 为每个生物标志物建立了特定地点的基线,不包括RDII影响.
- 使用氨-N作为稀释的代理,并将生物标志物衍生的稀释与测量流量数据进行比较.
主要成果:
- 基于生物标志物的稀释量计与测量流量数据相对应得很好.
- 在某些情况下,生物标志物表明稀释量高于测量流量.
- 这些差异归因于WWTW的流量损失,原因是结合下水道溢出 (CSO) 和风暴坦克.
结论:
- 基于生物标志物的稀释测量为直接流量测量提供了一个强大的替代方案.
- 这种方法提高了WWTW的运营优化,并为WBE提供了有价值的数据.
- 在WWTW的直接流量测量可能会低估由于CSO和风暴坦克激活的目标分析负载.

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.
Microbial Wastewater Treatment
Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
