摘要 水体微塑料污染范围广、污染程度深、潜在危害大,已引起较多研究人员的关注。目前,关于水体微塑料的去除技术已有大量研究,但尚缺乏全方面的综述报道。介绍了水体微塑料的污染现状,重点归纳阐述了水体微塑料的去除技术。常见的水体微塑料去除方法主要包括生物法、物化法(高级氧化法、絮凝沉降法)、物理法(格栅截留法、高级过滤法)和协同去除法。其中,絮凝沉降法、过滤法和协同去除法对水体微塑料的去除效率较高。最后,针对实际水体微塑料稳定性较强、难以彻底去除的问题,对未来研究方向提出发展建议,认为高级氧化技术发展潜力大,各种技术对微塑料去除机理需重点探究,以优化技术方案,为我国微塑料污染水体的安全治理提供新方法和新途径。 Aquatic microplastics have attracted the attention of numerous researchers owning to the widespread distribution,serious pollution situation and huge potential threat.Lots of studies regarding the removal technologies of microplastics from aquatic environment have been reported.However,a comprehensive summary in this field was still lack.The current situation of global aquatic microplastics pollution was introduced,and the removal approaches of microplastics from water were reviewed in detail.The common degradation methods consisted of biodegradation,physico-chemical processes(e.g.advanced oxidation and flocculating settling),physical processes(e.g.grille interception and advanced filtration)and multi-treatment methods.Among these methods,the flocculating settling,filtration and multi-treatment process exhibited superior removal efficiency.Additionally,some perspectives were proposed towards future research based on the stability and recalcitrance of microplastics.Advanced oxidation appears as a promising candidate for microplastics degradation.Besides,the mechanism of microplastics degradation still needs to be paid more attention in order to optimize the removal methods of aquatic microplastics.New approaches and routes for safety management of aquatic microplastics will be provided in China.
