Abstract:

In order to investigate the effects of wastewater on soil properties an experiment was conducted in Islamic AzadUniversity, Shahr-e-Qods Branch, Iran by measuring essential features related to soil characteristics. For this end, we used of 9 lysimeters that lysimeters of 1, 2 and 3 were irrigated by domestic wastewater and first drainage water accumulated from these lysimeters. Lysimeters of 4, 5 and 6 were irrigated by this water and secondary drainage water accumulated from upon lysimeters. To compare soil properties lysimeters of 7, 8 and 9 were irrigated by normal water and finally, soil and water properties analyzed in each stage. The results indicated that soil could filtering the wastewater and reduced BOD5 and COD of wastewater sorely. Also, irrigation with wastewater increased nutritive elements in soil that can be source of nutrition for plants. Our findings may give applicable advice to commercial farmers and agricultural researchers for management and proper use of water.
