Abstract: A petrochemical company has two anaerobic filters used to treat high concentration petrochemical wastewater. The start-up of anaerobic filter is the aerobic sludge which is transformed with the same kind of water.In the past 6 years of operational cycle,the anaerobic filter has been subjected to such abnormal operation as low load,acidification and so on. Finally,the removal rate of the anaerobic filter has been decreased greatly due to the hardening of the packing,blockage of the water inlet pipe,and accumulation of inorganic mud. The treatment of high concentration petrochemical wastewater with anaerobic filter has the advantages of high removal rate,good impact resistance and short recovery time,but the long overhaul time after the hardening of the packing is the biggest disadvantage of the process.
