概括

新的方法估计了美国饮用水处理厂 (DWTP) 和废水处理厂 (WWTP) 的污泥产量. 这些简单的,数据驱动的方法改善了国家污泥处理和回收估计.

科学领域:

环境科学环境科学
环境工程环境工程
废物管理废物管理

背景情况:

美国饮用水处理厂 (DWTP) 和废水处理厂 (WWTP) 的污泥管理数据往往没有向美国环境保护局 (U.S. EPA) 报告.
目前用于估计污泥处理的方法依赖于资源密集的调查.
为了准确的国家污泥管理评估,需要改进估计方法.

研究的目的:

通过公开可用的州级数据开发简单,透明的方法来估计每年污泥的产生和处置.
为DWTP和WWTP污泥提供更准确的国家估计.

主要方法:

通过使用供水数据和从文献中获得的污泥生成因子 (SGF) 来估计DWTP污泥生成.
来自15个州的WWTP污泥数据,重点关注垃圾填埋场的组成,用于推断国家数据.
根据州级数据计算了国家污泥产生和处置的估计值.

主要成果:

从2000年到2015年,DWTP污泥产量估计为每年3500万至4000万公干重量 (mmt dw).
据估计,WWTP污泥的产量为每年7.5-6.8毫,从2010年到2020年处置量为每年7.9-7.1毫.
由于现有的信息有限,无法对WWTP污泥的全国焚烧数据进行可靠估计.

结论:

使用公共数据的简单估计方法可以改善国家污泥产生,处置和回收数据.
这些方法为传统的数据密集型调查提供了更容易获得的替代方案.
需要进一步的研究来改善污泥焚烧量估计.

关键词:

饮用水饮用水饮用水焚烧是一种焚烧方式.垃圾填埋场是一个垃圾填埋场.量化量化量化量化处理污泥的处理污泥废水是废水,废水就是废水.

Microbial Wastewater Treatment

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 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...
