摘要
我国土地资源丰富,但总体状况较差。挥发性有机污染物是典型的土壤污染物。对于土壤中挥发性有机污染物的治理有原位修复和异位修复两种大的分类。本文介绍了原位修复技术中的气相抽提技术、生物通风技术、土壤淋洗原位修复技术、生物氧化技术、热处理技术、原位化学氧化技术和生物修复技术,及其主要优点和主要流程。介绍了异位修复法中的焚烧,热解吸和淋洗技术。展望了对于土壤中挥发性有机物的治理工艺的重点研究方向。
China is rich in land resources,but the overall soil environment is poor,has serious pollution.Volatile organic compounds are typical soil pollutants.The management of volatile organic compounds in the soil divides into two large classifications for in situ repair and ectopic repair.SVE,BV,in situ remediation through soil flushing technology,bio-oxidation technology,thermal treatment technology,in situ chemical oxidation technology and bioremediation technology,and their main advantages and main processes were introduced.The incineration,thermal desorption and flushing technology in ectopic repair were also introduced.The key research directions for the treatment of volatile organic compounds in soil were prospected.
