【 摘 要 】

Problem statement: The wastewater from petrochemical complex is varying in flow, organic contaminant loading and composition due to various operating condition of the petrochemical complex. This study is demonstration case of petrochemical wastewater treatment plant. Approach: This study is demonstration case on Basrah petrochemical wastewater treatment plant whereas the description of wastewater composition and system of treatment had reviewed and the experimental work on the most important control parameters (F/M ratio and MCRT) had implemented. Results: The experimental results showed that (i) The optimum rate of BOD removal could be obtained at food to microorganism ratio between 0.1-0.15 where this optimum ratio exists at the maximum zone settling velocity (ii) The design effluent BOD5 could be obtained at a MLSS concentration of 6000 mg L^-1 and in about 26-30 day of mean cell residence timeConclusion: The experimental data from petrochemical wastewater treatment plant in Basra City (south of Iraq) showed that the extended Aeration offers the most desirable features for the treatment of petrochemical wastewater where the specification of this method apply with experimental results as well as that the study show that control parameters (F/M ratio and MCRT) is a good toolto control the effluent wastewater quality ofpetrochemical wastewater treatment plant.
