垃圾渗滤液中COD在饱水带迁移的模拟研究
Simulating Migration of COD from Landfill Leachate in Saturated Water Zone
摘要
Abstract
[ Objective ] The aim was to simulate the migration of COD from landfill leachate in saturated water zone. [ Method ] COD from Likeng landfill leachate in Guangzhou was selected as the characteristic contaminant. Soil samples of the saturated water zone on both sides of drain were collected. Relevant parameters of the model were obtained by experiments, and the migration model of COD was established. Considering the differences of different field ages in leachate concentrations of COD, different concentrations were taken as boundary conditions to make the COD environmental impact assessment based on groundwater quality standards. [ Result] The COD decay occurs mainly within 10 m away from the drain (attenuated by 83％ ). The most long-distances that old, middle-aged and young landfill leachate polluted the groundwater into the Class Ⅲ water and the Class V water were 29.2, 37.2, 47.9 m and 27.1, 33.2, 44.1 m, respectively. [ Conclusion] The research provides theoretical basis for groundwater antipollution around landfill.关键词
