| Abstract: | The transformation of dissolved organic matter in sequencing batch reactors was investigated, which proposed practical wastewater with different operational parameters. The impact of sludge retention time (SRT) was mainly analyzed with respect to the characterization of effluent organic matter (EfOM) in sewage effluent from SBR. The results revealed that humic-like substances with molecular weight (MW) of 650Da, 1700Da and 2000Da were accumulated during the biological degradation process. Medium MW (500Da~3000Da, humic substances) and large MW organic materials (>10000Da, SMPs) were transformed by low MW organic materials. The molecular weight distribution of EfOM in sewage effluent was rarely impacted by SRT, only intensity difference in MW of 650Da and 20000Da was observed, which means that a longer SRT was helpful for the degradation of humic-like substances and SMPs. |
