摘要: Abstract In high-rate activated sludge (HRAS) systems, extracellular adsorption and intracellular storage have been referred to as the dominant mechanisms for capturing organic carbon from wastewater. However, quantification of products under short retention time (SRT) HRAS systems has rarely studied. Since measurement is complex dependent on several variables, alternative solutions substrate removal through are required understand system’s capture efficiency. To overcome complexity experimentally, this study proposes a fundamental approach determining soluble domestic A partitioning was used which represents influent total chemical oxygen demand (COD) storage, polymeric substance, biomass growth energy production. The based stoichiometric analysis showed that accounted 7–11% COD in A-stage operated at SRT range 0.3–2 d. also dissolved (DO) level increased 8% 30% (influent COD) when DO decreased 2 0.01 mg/L 1.5
