Removal of priority PAHs from coking wastewater
Journal Title: Civil and Environmental Engineering Reports - Year 2013, Vol 1, Issue 10
Abstract
The purpose of these tests described in this study was to determine the effectiveness of removing eight aromatic compounds from the list of priority. Tests were carried out using coke produced during wastewater treatment of coke oven gas. The technology research was consisted in introducing into wastewater samples taken with 30% solution of hydrogen dioxide (50 mg/dm3, 100 mg/dm3, 300 mg/dm3, 600 mg/dm3, 900 mg/dm3, 1000 mg/dm3, 2000 mg/dm3). The PAHs analysis included: sample preparation, quantitative and qualitative chromatographic determination, it was also carried out using gas chromatography coupled with mass spectrometer. Total concentration of PAHs in the effluent eight coke before oxidation was 23 μg/dm3. The largest loss of hydrocarbons examined, reaching 62%, was noted at the dose of 50 mg/dm3 of the oxidant.<br/><br/>
