Extraction of Chemical Fingerprint in Food Industry Wastewater

Abstract:

Wastewater source tracing technology is a method to find the pollution wrecker based on wastewater chemical fingerprint database. How to extract and verify the chemical fingerprints of each factory is the key technology. Here report the extraction of chemical fingerprint by taking two factories (food brewing and food processing factories) surrounding Tong Zhou North Canal (Beijing) as representatives. Firstly, the organic chemicals, anions, heavy metal ions in wastewater are detected respectively by gas chromatography-mass spectrometry (GC-MS), ion chromatography (IC), inductively coupled plasma mass spectrometry (ICP-MS) and three-dimensional excitation emission matrix fluorescence spectroscopy (3D-EEM). According to the screening principles of chemical fingerprints, the pollution and characteristic fingerprints of two factories are identified. Finally, the simulated water samples were used to test the stability and feasibility of the extracted chemical fingerprints.
