摘要
Abstract
In order to clarify the water quality characteristics of the secondary biochemical treatment effluent from coal gasification wastewater,ultrafiltration is applied to classify the molecular weight of the wastewater,XAD-8 resin is used for separation,and spectral analysis is performed.The results show that among the components with different molecular weights,hydrophobic substances account for a greater proportion than hydrophilic substances,with hydrophobic neutral organic compounds(HoN)having the highest proportion.Three dimensional fluorescence spectroscopy analysis finds that hydrophobic organic acids(HoA)and HoN have a higher degree of humification,and hydrophobic organic bases(HoB)contain more aromatic compounds and fulvic acid organic compounds,while hydrophilic organic compounds(HI)contain more fulvic acid organic compounds and soluble microbial metabolites.关键词
