MBR+蠕虫床耦合系统内胞外聚合物三维荧光特性
Study on characterization of extracellular polymers in MBR-sessile worm reactor system by using three-dimensional excitation and emission matrix fluorescence spectroscopy
摘要
Abstract
Fluorescence excitation emission matrix spectroscopy(EEMS)was used to study the impact of worms on the extracellular polymers( EPSS and EPSB) in MBR - sessile worm reactor system. There were four peaks in MBR - A,MBR - B and SSBWR. SSBWR did not destroy the tyrosine s structure of EPSS in MBR - B, however, lead to a large read shift of tryptophan. Those two kinds of protein, fulvic acid-like and humic acid-like increased greatly in quantity. Two peaks were found in the EEM of EPSB in the combined system, which was tyrosine and tryptophan. So, EPSB was consisted of substances like protein. SSBWR lead to a significant decrease in the quantity of those two kinds of protein, in addition, result in a 5 ~ 10 nm blue shift in the peak of tryptophan. After sludge mixed liquor in MBR - B was predated by worms in SSBWR, I(B)/I(A) decreased at a certain degree. The amount of organic matter which was easily degraded in sludge mixed liquor and the biodegraded ability droped, due to the predation of worms.关键词
