国外土壤修复专利技术分析与展望

Analysis and Prospect of Foreign Soil Remediation Patent Technology

  • 摘要: 土壤污染不仅破坏土壤质量和土地生产力,而且对水体和大气环境产生不同程度的污染,这将直接危害人体健康,对生态环境造成威胁。我国土壤污染治理起步较晚,探索国外土壤污染修复技术在生态环境保护领域的应用对改善我国土壤质量具有重要的意义。根据我国地域特色、土壤污染类型和土壤修复现状,对国外先进土壤修复专利技术进行了深入调研。从生物修复、物理修复、化学修复、复合修复四方面总结了国内外土壤修复现状和技术特点;选取了国外土壤修复领域的典型专利技术进行深入剖析,分析了这些土壤修复技术在我国的可行性及应用前景。通过对国外土壤修复专利技术的分析发现,相较单独的化学或物理修复手段,复合修复法具有效率高、成本低、机动性强的优点。复合修复法将成为今后土壤修复乃至生态环境修复领域中的主要技术形式和研究的重点。展望了我国土壤修复技术今后的发展方向,旨在为我国土壤修复技术的探索和提升提供一定的参考。

     

    Abstract: Pollution will not only destroy the quality and the productivity of the soil, but also threatening the water, atmospheric environment, and ecological safety. Domestic soil pollution control started relatively late, exploring the application of foreign soil pollution remediation technologies is of great significance to improving soil quality in China. In this study, the advanced technologies of soil remediation were investigated based on the regional characteristics, pollution types, and soil remediation status. The current status and technical characteristics of soil remediation at home and abroad were summarized from the aspects of biological remediation, physical remediation, chemical remediation, and composite remediation. The typical technologies of foreign soil remediation were deeply analyzed. The feasibility and application prospects of these technologies in China were also evaluated. Compared with the separate chemical or physical remediation, composite remediation with advantages of high efficiency, economy, and flexibility. Therefore, it can be concluded that the composite remediation may become the main method of soil remediation and environmental remediation in the future. Furthermore, the development direction for soil remediation was forecasted, aiming to provide some reference for exploration of soil remediation technology in China.
