镉及邻苯二甲酸酯复合污染农田土壤的修复技术研究进展

Research Progress in the Soil Remediation Technology for Cadmium and Phthalate Compound Contaminated Farmland

因化肥和农用薄膜塑料等的大量使用造成了我国农田土壤呈现出越来越明显的复合污染,其中镉及邻苯二甲酸酯就是一种典型代表。基于修复原理在概述单独镉污染土壤、单独邻苯二甲酸酯污染土壤的修复技术基础上,归纳总结了镉及邻苯二甲酸酯复合污染土壤的物理修复、化学修复及生物修复技术方法及各技术的优缺点,最后提出了镉及邻苯二甲酸酯采用联合修复的建议。

The massive use of chemical fertilizers and agricultural plastics thin film has resulted in more and more obvious combined pollution of farmland soil in China,among which cadmium and phthalic acid esters are typical representatives.In this paper,based on the principle of soil remediation,the remediation technologies of separate Cd contaminated soil and separate phthalic acid esters contaminated soil were introduced.Various remediation technologies for cadmium and phthalates combined pollution soil were summarized,such as physical remediation,chemical remediation and bioremediation methods.And their advantages and disadvantages were discussed.Finally,some advice on the remediation of cadmium and phthalates combined pollution soil was proposed.
