چکیده:

In this experiment, we had 9 lysimeter that 1, 2 and 3 lysimeters irrigated by domestic wastewater. Then, first drainage water accumulated from these lysimeters and 4, 5 nd 6 lysimeters irrigated by this water and secondary drainage water accumulated from upon lysimeters. In order to comparison biological and microbial characteristics, 7, 8 and 9 lysimeters irrigated by agronomical water and finally, soil and biological and microbial characteristics of water analyzed in each stage. The results showed that soil could iltering the wastewater and reduced BOD5 The use of wastewater by farmers will not go away. It can’t be ignored or dealt with by imposing bans on its use. Municipal policy-makers and planners need to confront reality and COD of wastewater. Also, irrigation with wastewater increased elements in soil that can be source of nutrition for plants.
