污染土壤修复的技术再造与展望

Technological reforger and prospect of contaminated soil remediation

污染土壤的面积在迅速扩大,迫切需要修复、治理;随着土壤污染组分的日益复杂化,等待着全面、高效的修复技术的研制。对污染土壤修复相关技术现状进行剖析表明,现有的各种污染土壤修复技术由于存在着许多技术上难以克服的问题,需要从技术的现有进展和技术构想进行整体意义上的创新,即如何把现有的技术进行参数优化、改造后进行最佳组合与综合,才能取得该技术领域的重大突破。污染土壤的生态化学修复,其实质在于技术的再造,代表了21世纪污染土壤修复技术的发展方向。

The area of contaminated soils is increasing rapidly and the components of soil contamination are becoming increasingly complicated. There is a great need for all-round and effective remediation technology for contaminated soils. It can be indicated by the systematic analysis of relevant current technology for the remediation of contaminated soils that there are many inherent technological problems that are difficult to overcome in practice. The future outlet is the holistic innovation based on current technological headway and conception. Technological breakthrough in the remediation of contaminated soils can be made only after the optimization of technological parameters and the integration of available improved technologies. In this sense, the eco-chemical remediation of contaminated soils is a technological reforger in essence, which can represent the developing orientation of contaminated soil remediation in the 21st century.
