狄氏剂污染土壤修复研究进展

Research Progress on Soil Remediation of Dieldrin

综述了物理、化学、生物修复技术及优选技术进行狄氏剂污染土壤修复的特点;其中物理、化学修复技术具有修复周期短、范围广,但易产生二次污染及成本高等特点;生物修复技术具有修复成本低、环境效益好,但修复周期长等特点;优选技术通过联合多种修复技术,其修复效果显著,但应用范围有限。结合各种修复技术的原理、优缺点及应用范围,微生物修复技术及各修复技术的联用是今后狄氏剂污染土壤修复的发展方向。

In the current research progress on the soil contaminated with dieldrin at home and abroad, the physical, chemical, bioremediation technologies and preferred technologies were reviewed. Among them, physical and chemical remediation technologies have the characteristics of short remediation period and wide usage range, but it is easy to produce secondary pollution when adopting physical and chemical remediation technologies and the cost is high. Bioremediation technology has the characteristics of low cost, good environmental benefit, and long remediation period. Combining various remediation techniques, the preferred technology has significant remediation effect. However, the scope of its application is limited. Combining the principles, advantages and disadvantages of the various remediation techniques and the scope of application, it is believed that in the future the combination of microbial remediation technology and various remediation technologies is the development direction of decontaminated the soil contaminated by dieldrin.
