Abstract  

The objective of this research was to evaluate the performance of stabilization ponds in wastewater treatment of the city of Birjand. The samples were taken from influent, anaerobic pond effluent, facultative pond effluent and maturation pond effluent for a year (April 2011 to March 2012). Laboratory analysis was carried out following standard methods for the analysis of temperature, pH, BOD5, COD, TSS and turbidity. Results of these investigations showed that the average effluent concentrations of BOD5, COD and SS taken from maturation pond were 109.17, 241.67, 74.65mg/L, respectively and effluent turbidity was 138.83 NTU. Also these results indicated that maturation pond effluent was not match with the Standards of Environmental Protection Agency of Iran for agricultural reuse in terms of BOD5, COD and turbidity. Hence based on this research, performance of Birjand stabilization ponds was poor and it need to upgrade.
