Abstract

Depending on effluent characteristics, irrigation with WASTEWATER PLANT EFFLUENT can be either beneficial or harmful. To investigate the effects of nine years of irrigation with North Isfahan WASTEWATER Treatment PLANT EFFLUENT on physical and chemical properties of soil, a study was carried out using a randomized complete block design with three replications. Treatments included: 1) raw WASTEWATER; 2) effluent from primary settling basin; 3) final PLANT EFFLUENT and 4) well water. To investigate soil physical and chemical properties, samples were taken from depths of 0-5 cm and 5-10 cm from each plot. The results showed that raw WASTEWATER COD and SS were higher than the Iranian Standard limits for use in irrigation. So were BOD5 and turbidity of effluent from primary sedimentation tanks. From the results obtained, the raw WASTEWATER may be considered to be of medium quality. However, regarding other parameters such as EC, SAR, Na and Pb, the quality of the raw WASTEWATER was considerably higher than that of well water. All treatments showed medium infiltrability with respect to chloride concentration. The concentration of lead in well water was higher than in treated WASTEWATER. It should be noted that lead concentration in all samples was less than the standard limits. The average soil bulk density and percentage of moisture in FC did not follow any specific trend. The results indicate that the soil irrigated with effluent over the nine years had a lower bulk density, a higher percentage of moisture, and a lower infiltration compared to adjacent soil not irrigated with WASTEWATER. Analysis of variance for all results did not confirm any significant differences among treatments.
