【摘要】：隨著我國經(jīng)濟的飛速發(fā)展，各種固體廢棄物垃圾產(chǎn)量也越來越多，我國已出現(xiàn)垃圾圍城現(xiàn)象。衛(wèi)生填埋是目前我國處理各種固體垃圾的首要手段，而垃圾填埋場中垃圾滲濾液的滲漏會造成周圍土壤、地表水和地下水的污染，對人類產(chǎn)生極大危害。電學(xué)檢測方法因其操作簡單、方便快捷、成本低廉、自動化程度高、屬無損檢測且沒有二次污染等優(yōu)點，成為各國學(xué)者研究的主要方向，但是目前國內(nèi)并沒有能夠?qū)崟r監(jiān)測滲濾液滲漏的成熟方法和電法設(shè)備。 電法勘探是根據(jù)研究對象的電學(xué)性質(zhì)差異，通過觀測和研究由電性差異引起的人工和天然電磁場的空間和時間分布規(guī)律的變化特點，達到查明地下結(jié)構(gòu)特征或礦產(chǎn)分布的地球物理方法。我們將其運用到垃圾填埋場的滲漏監(jiān)測中，通過與背景場區(qū)的電位值、電阻率和膜間電阻的處理對比，我們可以判斷是否有滲漏點存在。 本論文經(jīng)過對垃圾填埋場的結(jié)構(gòu)進行分析、簡化，，提出了等效電法監(jiān)測模型。用實驗槽模擬實際垃圾填埋場場區(qū)，對比研究電位法、電阻率法和膜間電阻掃描法對不同滲漏狀況的監(jiān)測效果。 研究結(jié)果表明：電位法和膜間電阻掃描法可以快速的檢測出漏點的位置和數(shù)目，并行電位法數(shù)據(jù)采集可以一次性采集場區(qū)內(nèi)所有測點的電位值，具有很強的實時性，故電位法可以實現(xiàn)對垃圾填埋場區(qū)內(nèi)滲漏的實時監(jiān)測。電阻率法數(shù)據(jù)采集無法實現(xiàn)多測點、大數(shù)據(jù)量的實時采集，有一定的采集周期，實時性較差，不適合用于滲漏的實時監(jiān)測。但電阻率法可以很好的對滲漏的擴散范圍和路徑進行檢測研究（水平方向和垂直方向），故可很好的用于垃圾填埋場外圍的滲漏檢測。 根據(jù)理論研究、實驗驗證及吉林大學(xué)工程研究所對電法監(jiān)測儀器的開發(fā)研究，形成了國內(nèi)首例完整的垃圾填埋場滲漏電法監(jiān)測系統(tǒng)，并將其成功應(yīng)用到內(nèi)蒙古東部某垃圾填埋場中。通過在垃圾填埋場的實際監(jiān)測效果表明，電位法監(jiān)測方法和其配套電法儀器完全能勝任實時監(jiān)測垃圾填埋場中滲濾液滲漏的任務(wù)。
[Abstract]:With the rapid development of economy in our country, the output of solid waste is more and more. Sanitary landfill is the most important way to dispose of all kinds of solid waste in our country at present, and the leachate leakage in the landfill site will cause pollution of soil, surface water and groundwater, which will cause great harm to human beings. Because of its advantages of simple operation, convenience, low cost, high degree of automation, non-destructive testing and no secondary pollution, electrical detection method has become the main research direction of scholars in various countries. However, there is no mature method and electrical equipment to monitor leachate leakage in real time. Electrical exploration is based on the electrical properties of the object of study, through observation and study of the artificial and natural electromagnetic field caused by the spatial and temporal distribution of the characteristics, A geophysical method for ascertaining the characteristics of underground structures or the distribution of minerals. We apply it to landfill leakage monitoring. By comparing with the potential value, resistivity and intermembrane resistance of the background field, we can judge whether there is a leakage point or not. In this paper, the structure of landfill is analyzed and simplified, and an equivalent electric monitoring model is put forward. The experiment tank was used to simulate the actual landfill site, and the monitoring effects of potential method, resistivity method and intermembrane resistance scanning method on different leakage conditions were compared and studied. The results show that the potential method and the intermembrane resistance scanning method can quickly detect the location and number of leakage points, and the data acquisition of parallel potential method can collect the potential values of all the measured points in the field area at one time, which has a strong real-time performance. Therefore, the potential method can realize the real-time monitoring of landfill leakage. Resistivity data acquisition can not realize multi-point real-time acquisition of large amount of data, there is a certain period of acquisition, the real-time performance is poor, so it is not suitable for the real-time monitoring of leakage. But the resistivity method can be used to detect the diffusion range and path of leakage (horizontal and vertical direction), so it can be used in the leakage detection of landfill. Based on the theoretical research, experimental verification and the development of electrical monitoring instruments by the Institute of Engineering of Jilin University, the first complete electrical monitoring system for landfill leakage in China has been formed. It was successfully applied to a landfill in eastern Inner Mongolia. The actual monitoring results in the landfill show that the potentiometric monitoring method and its associated electrical instrument can be used to monitor the leachate leakage in the landfill in real time.
