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.
