本文综述了芬顿在多环芳烃污染土壤处理中的应用。首先介绍了均相催化剂（传统的和改性的芬顿）和非均相催化剂（类芬顿）催化芬顿处理废水的背景和原理。实验室和现场土壤修复研究的效率，动力学和相关因素进行了讨论。综述了芬顿综合处理的4种主要方式，即物理-芬顿、生物-芬顿、电-芬顿和光-芬顿。对于每一个这些综合修复技术，理论背景和机制的详细旁边与可实现的去除效率相比，单一的芬顿处理污染土壤中的多环芳烃。最后，芬顿为基础的土壤处理的环境影响进行了记录和讨论。
This paper aims to review the applications of Fenton based treatments specifically for polycyclic aromatic hydrocarbons-contaminated soils. An overview of the background and principles of Fenton treatment catalysed by both homogenous (conventional and modified Fenton) and heterogeneous (Fenton-like) catalysts is firstly presented. Laboratory and field soil remediation studies are then discussed in terms of efficiency, kinetics and associated factors. Four main scopes of integrated Fenton treatments, i.e. physical-Fenton, biological-Fenton, electro-Fenton and photo-Fenton are also reviewed in this paper. For each of these integrated remediation technologies, the theoretical background and mechanisms are detailed alongside with achievable removal efficiencies for polycyclic aromatic hydrocarbons in contaminated soils compared to sole Fenton treatment. Finally, the environmental impacts of Fenton based soil treatments are documented and discussed.
