    摘要:

    新污染物(emerging contaminants,ECs)具有浓度低、毒性大等特点,是饮用水和再生水水质安全的重要威胁。生物炭因制备成本低、处理效率高等特点,在水环境ECs的去除领域受到广泛关注。为了推进生物炭在水环境新污染物去除的应用,本文从水环境中ECs污染现状、生物炭的性质、生物炭在水环境ECs去除过程中的研究和应用等方面进行综述,分别总结生物炭作为吸附剂、高级氧化催化剂与微生物固定化载体对ECs的去除研究进展,并提出展望。

    Abstract:

    Owing to the properties of low concentration and high toxicity,emerging contaminants (ECs) have become one of the major threats to water safety.Biochar has attracted extensive attention in the removal of ECs from aquatic environment due to its easy accessibility and high treatment efficiency.In order to promote the application of biochar in the removal of ECs,in this paper the pollution status of ECs ,the properties of biochar,and the research and application of biochar in the removal of ECs in aquatic environment were reviewed.The research progress of removal of ECS by biochar as absorbents,advanced oxidation catalysts and microbial immobilization carriers was summarized,and the prospect was put forward.
