Research progress and prospect of low-carbon biological technology for nitrate removal in wastewater treatment

Frontiers of Environmental Science & Engineering, Journal Year: 2024, Volume and Issue: 18(7)

Published: March 25, 2024

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.

Microalgal-bacterial granular sludge can remove complex organics from municipal wastewater with algae-bacteria interactions

Communications Earth & Environment, Journal Year: 2024, Volume and Issue: 5(1)

Published: June 24, 2024

Abstract Interactions between algae and bacteria are pivotal in transforming complex organics for microalgal-bacterial granular sludge process, but the intrinsic removal mechanisms have not been well understood. Here, we investigate by which removed from municipal wastewater. Complex can be disposed during day-night cycles, significantly impacted carbon-to-nitrogen ratio influent. Upregulated gap2 gpmA genes enhanced conversion of into CO 2 , mediated interactions Chlorophyceae with Acidobacteriae / Sumerlaeia Fimbriimonadia upregulated petH gene Cyanobacteria strengthened fixation biomass. The breakdown starch, glycerol, fatty acid were depended on Actinobacteriota Chloroflexia Verrucomicrobiae Desulfobacterota I respectively. These findings provide new insights through symbiosis contribute to our understanding carbon cycle natural aquatic ecosystems.
