Removal of priority PAHs from coking wastewater

摘要: The purpose of these tests described in this study was to determine the effectiveness removing eight aromatic compounds from list priority. Tests were carried out using coke produced during wastewater treatment oven gas. technology research consisted introducing into samples taken with 30% solution hydrogen dioxide (50 mg/dm, 100 300 600 900 1000 2000 mg/dm). PAHs analysis included: sample preparation, quantitative and qualitative chromatographic determination, it also gas chromatography coupled mass spectrometer. Total concentration effluent before oxidation 23 μg/dm. largest loss hydrocarbons examined, reaching 62%, noted at dose 50 mg/dm oxidant.
