环境中短链氯化石蜡去除方法的研究进展

短链氯化石蜡（SCCPs）是2017年新定义的持久性有机污染物（POPs），能对人体健康及生态环境造成重大危害。现阶段国内外关于SCCPs的研究工作主要集中在环境中SCCPs的分析检测方法和浓度水平分布规律，对SCCPs的高效去除方法及去除机理的研究较少。本文主要综述了现阶段SCCPs的有效去除方法，包括物化法（一般物化法和高级氧化处理）和生物法（细菌降解和植物吸收法），对比分析了这些方法的优缺点，讨论了不同方法去除SCCPs的影响因素、可能降解机理及途径，并通过类比借鉴，提出了其他具有可行性的去除SCCPs的方法。总体而言，虽然物化法去除效率高，但是成本高且操作条件苛刻，微生物法因经济环保而具有更大的发展潜力，但若将微生物法与物化法联用，则有可能发展成为最佳去除工艺。最后展望了环境中SCCPs去除方法的研究重点。

Review on removal methods of short-chain chlorinated paraffins in environment

Short-chain chlorinated paraffins (SCCPs) which are newly defined persistent organic pollutants (POPs) in 2017 are of significant harm to human health and ecology. Nowadays, the research work on SCCPs mainly focuses on the analysis and detection methods and concentration level distribution of SCCPs in the environment, but there are few researches on efficient removal methods and removal mechanism of SCCPs. In this paper, the current effectively removal methods of SCCPs are reviewed, including physicochemical methods (general physicochemical methods and advanced oxidation processes) and biological methods (bacterial degradation and plant absorption). In addition, the merits and demerits of each method are compared and analyzed, accordingly pointing out the possible influencing factors, degradation mechanisms and pathways of removing SCCPs by different methods. Moreover, some other feasible SCCPs removal methods are put forward by analogy. On the whole, although the physicochemical methods have high removal efficiency, the cost is high and the operating conditions are harsh, so microbial methods have greater development potential due to their economic and environment-friendly characteristics. On this basis, it is recommended that the microbial methods combined with physicochemical methods will have the potential to develop into the best removal process. Finally, the research emphasis of SCCPs’ removal methods in the future is also prospected.
