Abstract: 

Introduction: Water for agriculture is one of the most important factors in arid and semi-arid areas and municipal wastewater treatment is an important resource for this purpose. Wastewaters even after treatment may contain many types of microorganisms that are pathogenic to humans and dangerous for the environment. Therefore, potential of transfer contaminations is a serious problem regarding use of treated wastewater for agriculture. Due to the risk of transfer contaminations through the use of wastewater, the study of transfer microbes in soil in recent decades has been of interest to researchers. Thereafter various irrigation techniques can be used associated with treated wastewater for agriculture. Accordingly, the present study was conducted on Fecal Coliform in the wastewater treatment in laboratory columns.
Materials and Methods: The present study was conducted in Agriculture Faculty of TarbiatModares University for 62 days in 2013. This study was conducted on Fecal Coliform in the wastewater treatment in laboratory columns, having 30 cm diameter and 60 cm height. They were irrigated using surface drip irrigation system (DI). Samples of the effluent and soil solutions were collected from the experimental columns after each irrigation events. Soil texture was clay-loam that was collected from south of Tehran wastewater treatment plant. Three models of one site sorbtion's model, attachment/ detachment two kinetic site and attachment/ detachment one kinetic site, were used for simulation of Fecal Coliform transport by inverse solution option of the HYDRUS-ID model. For calibration of the model and estimating the model input parameters, soil hydraulic and transport parameters were inversely estimated. Results represented that the HYDRUS-1D with reasonably accurately simulated the outlet flow. To simulate the transfer of the bacteria in the soil, one site sorption model, two kinetic sites model (particle transport using attachment/detachment) and one kinetic site model were used.
