污染土壤修复技术的探讨

An analysis of Several Remediation Technologies of the Contaminated soils

污染土壤修复技术目前广泛应用的是生物、换土、固化及淋洗修复技术等,对前3种修复技术在处理污染土壤的效果和过程上进行分析和对比,其结果表明都存在着优缺点。通过对污染土壤淋洗技术的定义及分类的了解和与前3种修复技术的比较,并在此基础上产生了移动式异位淋洗修复技术介绍了它的工艺流程及各机械装置的作用,通过对照原有的污染土壤淋洗修复技术,其表明移动式异位淋洗修复技术具有可移动性、修复效率高等特点,具有很大的工程应用价值。

Most commonly used remediation technologies for soil contamination include bioremediation technology,soil replacement remediation technology and solidification technology at present. Through analysis and comparison, the disadvantages of these three remediation technologies were listed. The drip washing technology of contaminated soil was defined and classified. On this basis, a mobile drip washing rernediation technology for contaminated soils was developed. The function of each mechanical device in drip washing technological process was introduced. By comparing the original drip washing remediation technology of contaminated soils, a conclusion was drawed that mobile drip washing remediation technology of contaminated soils has mobility and high efficiency characteristics and has a great application value.
