Migration of Soil Salinize-alkalization and Heavy Metals in the Process of Reclaimed Water Irrigation
摘要
Abstract
In this paper,tap water was contrasted with the reclaimed water from the second wastewater treatment plant of Gaomi.The soil column simulated experiments were adopted to study the accumulation-migration of soil salinize-alkalization and heavy metals in two different irrigation patterns,and analysis the quantity of heavy metals in the filtrate.The results showed that the total dissolved solid of 0 to 20 cm soil layer increased.Compared with tap water irrigation,no significant difference can be detected for the content of the total dissolved solid in 20 to 60 cm soil layer.The distribution on pattern of heavy metals in soil system indicated no accumulation evidence of heavy metals was found,meanwhile,no significant difference can be detected for the contents of heavy metals with tap water irrigation pattern.The quantity of heavy metals in the filtrate reduced,and all of the heavy metals met the second standard of Groundwater Environmental Quality Standards(GB/T 14848—93).关键词
