摘要
为全面系统地研究垃圾渗滤液迁移规律,科学地分析污染物运移规律和预测污染物浓度分布情况,通过垃圾渗滤液的动态淋溶试验,研究了垃圾渗滤液主要污染物包括有机物(CODCr)、Cl-、SO42-、总硬度等在土壤水环境中的运移机理,试验结果表明迁移速度最快和最慢的分别为Cl-与有机物(CODCr);并对建立的一维数学模型求解表明,模型曲线与COD试验曲线较好的吻合,说明所建数学模型模拟有机污染物的有效性。
In order to completely and systematically study the landfill leachate＇s transfering rule and scientifically analyze the moving regulation and forecast concentration distribution of the pol- lutant, through the dynamic leach experiment for the landfill leachate, main pollutant components in landfill leachate were studied as organic （CODcr）,Cl-,SO42- and total hardness moving in soil water environment. The experiment results showed that the fastest and slowest transfering speed was Cl- and organic contaminant（CODc,） respectively. The solution by the one-dimensional mathematical model indicated that model curve and experiment curve of COD were consistent. It explained the validity of mathematical model for simulating the organic pollutamt.
