In this study, wastewater based on today's increasing urbanization, the increasing discharge of it, by treatment and mixing equal amounts for reuse in agricultural production have been assessed. The conclusion has been reached that maize can be grown using waste water in agriculture but significantly would affect without controlling of the heavy metal treatment.Macro elements such as N, P, K, Ca, Mg, trace elements such as Fe, Cu, Zn, Mn, and heavy metals such as Pb, Ni, Cd and B were analyzed on different organs of the maize plant grown with the water used in the trial.Upon entering service of treatment plants the positive and negative effects of waste waters in agriculture were examined. It was concluded that the use of waste and wastewater-derived mixtures would significantly affect the wasteland of soils and the rate of microbial contamination and the continuity of contamination
