摘要
The treatment of high-strength petroleum refinery effluent (PRE) with [BOD5]/[COD](0) = 0.14 was investigated using combined Fenton-sequencing batch reactor (SBR). The effect of [H2O2]:[COD](0) molar ratio on biodegradability enhancement was investigated. Fenton optimal conditions were: [H2O2]:[COD](0) of 6, [H2O2]:[Fe-0] of 10 and pH = 3.0 that could remove 76.5%, 45% and 96% of COD, TOC and phenol and increased biodegradability ratio to 0.37. The pretreated PRE subjected to SBR for one single cycle of 10 h. The results revealed the effectiveness of hybrid Fenton-SBR system in treating PRE where the complete treatment of the PRE was attained by this system.
