英文摘要： With the financial support of the NSFC project (Grant No. 50878203) and the efforts of our group, this work has been completed successfully based on th principal theories of spectroscopic chemistry and advanced spectroscopic chemical analytical means. The spectroscopic characteristics of effluents from anaerobic wastewater treatment reactors have been elucidated. So far all of the research objectives have been achieved. Various spectroscopic signals of anaerobic metabolic products have been obtained; new methods to characterize the excitation-emission matrix (EEM) fluorescence and Fourier transform near-infrared (FT-NIR) spectra have been developed, a series of new ways to analyze the properties of effluents from anaerobic wastewater treatment reactors have been established; several stoichiometric model describing the relationship between spectral signals and bioreactor performance have been established and used for the data analysis; an on-line spectroscopic monitoring system for anaerobic reactors ahs been constructed. The results from this work could provide solid therotical foundations and technical guidelines for the spectroscopic analysis, monitoring and operation of anaerobic bioreactors for wastewater treatment. So far, 12 paper have been published in SCI journals, and 1 paper is in press. Three patents are pending.
