چکیده مقاله
Present study tries to demonstrate the crucial role of assesmenting the quality of Eshtehard treated wastewater, located in the southwest of Alborz province, Iran, on suitability for groundwater recharge and its irrigation uses based on local IDOE and global FAO standards By taking and analyzing three wastewater samples from WWTP wastewater treatment plant for physicochemical, microbiological and heavy metals the experiment was carried out during spring and summer, April to August 2019 Analytical results indicated that all parameters such as pH, electrical conductivity, major ions Na , K , Ca2 , Mg2 , HCO3 , CO32 , Cl , SO42 , NO3 , BOD5, COD, Coliform and Focal Coliform have an increasing trend over time and the values that were obtained in June and August were above the limited standard values and the results of most of the irrigation indices such as TH, SAR, RSC, SP and MAR were above the limited standard values Therefore, most of the samples were not suitable for reuse The analysis of heavy metals As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn has also done, although the concentration changes varied over time for the elements, all were below the allowed limit and the effluent was not contaminated
