摘　　要：研究垃圾填埋渗滤液土壤污染准确检测问题。渗滤液进入深层土壤后,土壤环境较为复杂,渗滤液在快速移动中,会与深层土壤中的各种矿物质和水分子结合形成外部静电电流干扰,造成渗滤液电传导性下降,使得渗滤液电导率降低。传统的电机格栅法是通过渗滤液的快速导电特征进行污染检测的,一旦渗滤液导电率受到干扰,电流波动会导致检测准确率降低。提出了一种电导差分信号处理的垃圾填埋渗滤液污染检测方法,通过获取垃圾填埋渗滤液土壤污染导电信号特征,建立多层污染细化等级模型进行检测。实验证明,改进算法能够避免由于土壤含水量过大造成的污染强度信号衰减的缺陷,提高了土壤污染程度检测的准确率。Research the accurate detection of waste landfill leachate soil pollution. The paper put forward a pollu- tion detection method of waste landfill leachate based on conductivity difference signal processing. By obtaining the conductive signal characteristics of waste landfill leachate soil pollution, a multilayer pollution levels refinement model was established. Experiments show that the method can avoid the defect of pollution strength signal attenuation caused by high moisture content in the soil, and improve the detection accuracy of soil pollution degree.
