Investigation on a up-flow anaerobic sludge blanket (UASB) treating real substitute natural gas wastewater (SNGW) with glucose addition was conducted. The UASB was analyzed and addition of glucose remained as co-substrate during the whole start-up period. Excellent treatment performance was achieved when SNGW was treated with 500 mg l-1 glucose. The anaerobic reactor was operated continuously at 35 ?C for 125 days. After increasing the organic loading rate, fluctuations in removal efficiencies were observed, which were partly reversible. At the end of the reactor operation, removal of chemical oxygen demand was 60% and 44% respectively. The organic loading rate and hydraulic retention time was 1.2 kg COD/(m3?day) and 72 hrs. Gas chromatography?mass spectrometry (GC/MS) analysis showed that the phenolic compounds decreased to a low level at this condition. The main phenols in the anaerobic effluent were phenol, m-cresol, o-cresol and 2-methyl-Naphthalene. The biodegradation process of microorganisms showed the effect on toxic organic compounds of SNGW with the glucose addition. On the whole, the system exhibited good stability in terms of COD and phenols, and was found to be efficient and convenient method for SNGW.
