Abstract

The composition spatial distribution and degradation properties of dissolved organic matter (DOM) in Micro Pressure Inner Loop bioreactor (MPR) at low temperature were analyzed by fluorescence excitation-emission matrix regional integration analysis (EEM-FRI) and ultraviolet spectroscopy (UV). The results showed that MPR had a good degradation effect on DOM in low temperature municipal sewage and the upper region can degrade high molecular weight DOM. At low temperature, the fluorescence components of DOM at different sites were not different, and there were tryptophan-like Peak T1 and Peak T2, but the fluorescence intensity of the same components was different. The content of aromatic protein-like substance in MPR was higher, the microbial metabolism and humic acid in sewage treatment process were lower and these fluorescent components were evenly distributed.
