基于专利文献分析的土壤污染修复技术发展现状与展望
The development status and future prospective of remediation technology for contaminated soils based on patent analysis
摘要
Abstract
The remediation of contaminated soil is a hot topic in the field of agricultural, ecological and environmental sciences. In this pa-per, the present research distribution, the main research themes and the develop trend of remediation technology for contaminated soil were analyzed based on patents in the period of 2005—2013 retrieved from the Derwent Innovation Index. The results showed that the number of patent applications related to soil remediation gradually increased in the world, suggesting the research in this field is more active in these years. China is not only the major country of patent application, but also the largest country of technology origin. The number of patents ap-plied increased year by year from 2005, especially after 2009. Patents related to polluted soil remediation also showed an interdisciplinary trend, and span across a wide range of disciplines, including chemistry, instruments & instruction, engineering, water resources and other aspects. Patent cluster analysis showed that arsenic, cadmium, lead, chromium pollution were the hot research fields, and contaminants sta-bilization in soil, phytoremediation, electrokinetic remediation, amendments addition, soil leaching, ion beam, separated and recovered the pollutants were the important technologies applied in soil remediation. It was also emphasized that the research and development activities in contaminants stabilization, phytoremediation, and amendments addition become more active after 2010. Based on the above findings, it is recommended that low-cost and high-efficiency technologies for soil remediation should be focused on developing, and current available technologies and theories should be applied in practice to provide increased social and economic benefits.关键词
