Abstract :
The stabilization ponds are more effective systems for treating of the wastewater whit high organic and hydraulic loading shocks. Therefore, those are most popular methods for municipal and many of industrial wastewater treatment. Module 1 of phase 1 has been done in Abadan wastewater treatment plant. The main objective of this study was investigation of the organic matter of loading on the application of wastewater treatment of Abadan industrial estate. In this study, The efficiency of Abadan wastewater treatment plant was studied over ten months from February 2004 to December 2005 . The general conditions and operation of the plant were considered and wastewater treatment indexes such as pH , COD , BOD5 , TSS , Total coli form and fecal coli form and helminthes ova in influent and effluent and loading of organic matter level were determined. The maximum removal efficiency of pollutants was in July. The average amounts of COD , BOD5 , TSS , total and fecal coli form and helminthes ova in effluent in July were 805 mg/l ,440 mg/l , 30mg/l,9/2×105 MPN/100ml 6/1×105MPN/100ml ,22 ova/l respectively. so, maximum and minimum volume loading level in the anaerobic ponds 694.6 &384.1 g BOD5/m3.d and maximum and minimum surface loading level in the facultative ponds 554 & 272.06 kg BOD5/ha. d were determined. These results showed that the amounts of these parameters (exception of the TSS) had significant difference with the standard limits recommended by Iran Department of Environment (DOE) for irrigation or discharged to surface water and recycling water for agricultural re-use. In this section, problems and proposals have been presented. For sanitary disposal and reuse of this effluent the optimization of existing system must be noted.
