The feasibility of a synergistic endogenous partial denitrification-phosphorus removal coupled anammox (SEPD-PR/A) system was investigated in modified anaerobic baffled reactor (mABR) for synchronous carbon, nitrogen, and phosphorus removal. mABR comprising four identical compartments (i.e., C1–C4) inoculated with precultured denitrifying glycogen-accumulating organisms (DGAOs), polyphosphate-accumulating organisms, bacteria. After 136 days operation, the chemical oxygen demand (COD), total efficiencies reached 88.6 ± 1.0, 97.2 1.5, 89.1 4.2%, respectively. Network-based analysis revealed that biofilmed community demonstrated stable nutrient performance under oligotrophic conditions C4. metagenome-assembled genomes (MAGs) such as MAG106, MAG127, MAG52, MAG37 annotated phosphorus-accumulating (DPAOs) MAG146 DGAO were dominated C1 C2 contributed to 89.2% COD consumption.

Functional gene based on metagenomic sequencing confirmed different capable performing distinct functions specific advantageous microbial groups, facilitating targeted Additionally, conditions, activity bacteria-related genes hzs higher compared hdh. Thus, an innovative method treatment low-strength municipal nitrate-containing wastewaters without aeration presented, mediated by process less land area excellent quality effluent.

Abstract Wastewater treatment plants are the major energy consumers and significant sources of greenhouse gas emissions, among which biological nitrogen removal wastewater is an important contributor to carbon emissions. However, traditional heterotrophic denitrification still has problems excessive residual sludge requirement external sources. Consequently, development innovative low-carbon nitrate technologies necessary. This review outlines key roles sulfur autotrophic hydrogen in treatment. The discovered nitrate/nitrite dependent anaerobic methane oxidation enables sustainable emission reduction by utilizing available situ . Photosynthetic microorganisms exhibited a promising potential achieve carbon-negative removal. Specifically, algal-bacterial symbiosis system photogranules offer effective prospective options for Then, emerging technology photoelectrotrophic underlying photoelectron transfer mechanisms discussed. Finally, we summarize prospect these technologies, highlighting that solar-driven area future guiding significance design systems.
