Introduction: Wastewaters resulting from seasonal processing such as pistachio processing industry are one of the most important factors of environmental pollution. High concentration of pollutants are the qualitative characteristics of wastewaters that due high consumption of water and energy resources as well as high levels production of waste have a good potential to realization of projects to reduce the environmental impacts and optimizing the consumption of energy resources.The aim of this study was to determine the wastewater̛ s quality and quantity of pistachio processing terminals.

Methods: this study is cross-sectional study that has been implemented from mid –September until late October (pistachio harvest season) in each of the years 2012-2013-2014 in Kerman.Firstely according to field study, the characteristics and location of 20 pistachio processing terminals were determined by a GPS device. Then 8 pistachio processing terminals were selected in around of wastewater collection system. Composite sampling method with total of 72 samples was done in each year during pistachio operation. Samples were conducted from pistachio processing wastewater screen filter outlet. In each of samples BOD5, COD, TSS, pH and Total phenolic were determined. Sampling and tests were done according to water and wastewater standard methods book (20th edition). Concentration of Phenolic compounds was measured by folin ciocaltive method. The Data was analyzed by SPSS software.

Results: the average of total produced wastewater in pistachio processing terminals in this study was 85.9m3/d. The average BOD5, COD, TSS, Total phenolic and PH were 6106, 21570, 682, 4154 (mg/L) and 5.5 respectively.

Conclusion: The obtained results from raw wastewater of pistachio processing terminals showed they have high BOD and COD. This is caused by presentation of priority pollutants (phenolic compounds) which have high potential in pollution and toxicity for discharging any receiving resources.
