Variation Characteristics and Removal Rate of Fluorescence Organic Matter in the Petrochemical Wastewater Treatment Process
Petrochemical wastewater is of huge quantity released during the production and complicated contaminants of petrochemical wastewater will have immense negative impact on ecology environment Three-dimensional excitation-emission matrix fluorescence(3D-EEM) was used to investigate the characteristic fluorescence of influent and effluent from each processing unit of Hydrolysis-acidification +A/O+ Contact-oxidation Process in a typical petrochemical wastewater treatment plant The results showed that there were 4 fluorescence peaks named Peak A, Peak B, Peak D, Peak E in the spectrum chart of influent, they are around λex/λem=220/300, 225/340, 270/300, 275/340 nm, the primary source of fluorescence organic matter(FOM) is industrial wastewater The fluorescence intensity of each fluorescence peak was decreased, while location was unchanged in the effluent of Hydrolysis-acidification Peak C appeared from the effluent of anaerobic tank at λex/λem=250/425 nm, then the fluorescence intensity of Peak C was enhanced in the effluent of aerobic tank Peak A disappeared from the effluent of secondary sedimentation tank The spectrum chart of the wastewater had no obvious variation after secondary sedimentation tank The removal rate of FOM was expressed with the degradation percentage of the fluorescence intensity, the total FOM was reduced by 920% after processing, and the removal rate of the FOM fluoresce around Peak A, Peak B, Peak D, Peak E were 1000%, 912%, 803%, 920% respectively A volatile IPeak B/IPeak E value of influent but a relatively stable value of effluent demonstrated that the wastewater treatment plant operated steadily and the process has higher capacity in resistance to shock loading
