Title: Effects of Irrigation with Reclaimed Water on Soil Salinize-alkalization and Heavy Metal Distribution
Abstract: Reclaimed wastewater is becoming one of the important water resources for irrigation,especially in arid and semi-arid areas.Experiments of irrigation with treated sewage effluent were conducted.During the period of experiments,tap water and secondary treated sewage effluent were used for irrigation,respectively.The experimental results showed that the total dissolved solid of 0 to 15 cm soil layer increased,the contents of soil cation were not obviously changed.The distribution on pattern of heavy metals in soil system indicated that no accumulation evidence of heavy metals was found.Meanwhile,no significant difference can be detected for the contents of heavy metals in soils irrigated with different quantities of treated sewage effluent.The concentrations of heavy metals in soil were found much lower than the critical values of Chinese National Standard.It therefore implies that short-term irrigation with reclaimed wastewater cannot result in soil environmental hazard.
