Key Data Set Information
Location SC-CN
Name
Municipal wastewater treatment ; Wastewater ; betwixt anaerobic and aerobic treatment
Use advice for data set When utilizing this data set for life cycle assessment, attention should be given to delineating the boundary conditions between anaerobic and aerobic treatment stages. Ensure that the energy consumption, biogas production, and any potential emissions from both stages are accounted for accurately. For scenarios where recycling or resource recovery is relevant, include considerations for sludge treatment and potential nutrient recovery.
Technical purpose of product or process This process, involving both anaerobic and aerobic treatment units, is used for the treatment of wastewater to remove or reduce organic matter, nutrients, and pollutants. It is applicable in industrial wastewater treatment facilities seeking efficient biodegradation and stabilization of organic substances.

  • ILCD: Unit processes / End-of-life treatment / Wastewater treatment
General comment on data set In the anaerobic treatment phase, anaerobic bioreactors such as anaerobic ponds or anaerobic fermentation tanks are employed, where organic matter is broken down into smaller organic compounds and gases in an oxygen-free environment. The aerobic treatment phase typically utilizes aerobic bioreactors such as activated sludge or biofilm processes, where organic matter and ammonia nitrogen are further oxidized by oxygen and aerobic microorganisms to meet discharge standards.

Technological representativeness
Technology description including background system In municipal wastewater treatment, anaerobic and aerobic treatment processes exhibit the following technical characteristics:Anaerobic Treatment:Reactor Design: Anaerobic treatment typically employs reactors such as anaerobic ponds or anaerobic fermenters, providing an oxygen-free environment to facilitate the degradation of organic matter by anaerobic microorganisms.Operating Conditions: Under anaerobic conditions, controlling parameters such as temperature, pH, and influent organic matter concentration is necessary to ensure the activity and reaction efficiency of anaerobic microorganisms.Aerobic Treatment:Reactor Design: Aerobic treatment typically utilizes reactors such as activated sludge or biofilm processes, providing sufficient oxygen and suitable conditions to promote the oxidation of organic matter and ammonia nitrogen by aerobic microorganisms.Operating Conditions: Under aerobic conditions, controlling parameters such as oxygen supply, mixing rate, and dissolved oxygen concentration is crucial to maintain the growth and activity of aerobic microorganisms.Related Upstream and Downstream Processes:Upstream Processes: Include wastewater pretreatment, such as screening, grit removal, and sedimentation, to remove large particles and settleable solids.Downstream Processes: May include sedimentation, filtration, etc., to separate and remove biomass flocs and suspended solids, ultimately producing treated water that meets discharge standards.
