有机污染场地生物修复技术挑战与展望

Challenges and Prospects of Bioremediation Technology for Organic Contaminated Sites

中国大中城市化工企业的大规模搬迁,致使大量工业污染场地遗留在城市周边。研发高效和成本低廉的修复技术,对于实现我国工业污染场地的绿色可持续发展具有重要意义。通过对现有物化和生物修复技术进行综述,指出生物技术在有机污染场地修复中的重要性,并从土壤环境和微生物两方面,分别总结了当前有机污染场地修复面临的挑战,并在高效、持久、稳定的菌剂和酶制剂,以及具有协同效应的生物修复助剂与微生物菌剂配合使用等方面,对有机污染场地生物修复技术研发提出建议。

The large-scale relocation of chemical companies in China's large and medium-sized cities has resulted in a large number of industrially polluted sites left over around the city.The research and development of high-efficiency and low-cost remediation technologies is of great significance for realizing the green and sustainable development of industrially contaminated sites in China.Through a review of the existing physicochemical and bioremediation technologies,the importance of biotechnology in the remediation of organically contaminated sites was put forward,and the current challenges faced by the remediation of organic contaminated sites the aspects of soil environment and microorganisms were summarized.Finally,further research suggestions were offered for the bioremediation of organically contaminated sites,including the development of efficient,durable and stable inoculants and enzyme preparations,as well as the use of synergistic bioremediation additives and microbial inoculants.
