Abstract:
Oil, gas and petrochemical projects are implemented to achieve the industrial development and economic benefits. The human welfare is one of the main anticipated aims for these projects. However, these projects result in vast environmental impacts. In this research, the rate of petroleum emulsion in Arvand River receiving a petroleum complex wastewater treatment effluent was investigated. Results showed that, the maximum concentrations of DO, COD and BOD were 7.2, 95.8 and 48.4 mg/L and the minimum concentrations were 1.64, 21mg/L and 4 mg/L respectively. The maximum concentration of oil and grease was 18.5 mg/L. Oil and grease content have not been observed in Arvand River during research period. It was also found the maximum concentrations of TSS, TDS and Hardness were 56, 8400 and 3762 mg/L and the minimum were 21 mg/L, 1740 mg/L and 680 mg/L respectively. The results revealed that the effluent quality from this complex does not meet the discharge standard to surface waters and the exiting treatment process is not sufficient. Therefore, a more advanced process is required and recommended.
