The removal efficiencies of petrochemical wastewater by upflow anaerobic sludge blanket reactor were average 74.6% and maximum 85.7%. pH was maintained between 6.7-7.4 which showed stable reactor conditions. Net production rate of metane and proportion of methane were 3.57L/m³·day and 77.7%, respectively. Other parameters about chemical state of reactor also confirmed stable activity of methanogenic bacteria. This result showed that anaerobic treatment of petrochemical wastewater and obtaining of methane gas from waste are possible. Futher studies about development of pretrement process, unit process, and methanogenic bacteria were required.
