LACSD BNR Pilot Plant Metagenomes

In this study, we aimed to evaluate Biological Nutrient Removal (BNR) and investigate microbial community changes when the DO is reduced in the aerated portions of wastewater treatment trains. We present a dataset of metagenomes obtained from activated sludge collected from the Los Angeles Sanitary District BNR pilot plant at the beginning of operation, when the DO was high, and at the end of operation, when the DO was low.

本研究旨在评估生物营养物去除（Biological Nutrient Removal, BNR）工艺的运行效果，并探究污水处理流程曝气区段内溶解氧（Dissolved Oxygen, DO）降低时，系统微生物群落的变化特征。本研究公开了一套宏基因组数据集，样本采集自洛杉矶卫生区BNR中试装置的活性污泥，分别获取于运行初期（曝气段溶解氧浓度较高时）与运行末期（曝气段溶解氧浓度较低时）。
