In this study, it is purposed to design the advanced treatment process of petrochemical wastewater more essential that improve removal efficiency of inert organic matters. Proper operating conditions and treatment process was determinated through computer simulation using a GPS-X model.
An A2O process using an ASM2d model of GPS-X was simulated for analyse of advanced treatment efficiency change of petrochemical wastewater process. The COD fractions in influent which influence was analyzed on the treatment efficiency in petrochemical wastewater process. Effects of SRT and the addition of coagulants on the treatment efficiency of inert organic matters are investigated.
From the analysis of influent COD fractions in petrochemical wastewater. The fraction of Ss, Si, Xs and Xi were 14.5%, 27%, 14.5%, and 44% respectively. It was analyzed that the ratio had doubled more than general sewage. From the simulation results considered the characterization of influent, removal efficiency of BOD5, COD, SS, TN and TP by using the A2O process, were 96%, 66%, 87%, 86% and 58%, respectively. The reason of low COD removal efficiency of effluent that it hardly treated inert organic matter in influent. Also, lower removal efficiency of TP was judged by the bsCOD concentration in petrochemical wastewater lower than sewage.
For improvement of efficiency in petrochemical wastewater treatment process, increased SRT in stages showed little change of efficiency. In case of coagulants addition, removal efficiency of COD and TP were 77%, 93% respectively. Also, soluble inert organic matters were more removal 25% and particulated inert organic matters were almost removed.
