Continuous discharge and persistence of antibiotics in aquatic ecosystem is identified as emerging environment health hazard. Partial degradation and inappropriate disposal induce appearance of diverse antibiotic resistant genes (ARGs) and bacteria, hence their execution is imperative. Conventional methods including waste water treatment plants (WWTPs) are found ineffective for the removal of recalcitrant antibiotics. Therefore, constructive removal of antibiotics from environmental matrices and other alternatives have been discussed. This review summarizes present scenario and removal of micro-pollutants, antibiotics from environment. Various strategies including physicochemical, bioremediation, use of bioreactor, and biocatalysts are recognized as potent antibiotic removal strategies. Microbial Fuel Cells (MFCs) and biochar have emerged as promising biodegradation processes due to low cost, energy efficient and environmental benignity. With higher removal rate (20-50%) combined/ hybrid processes seems to be more efficient for permanent and sustainable elimination of reluctant antibiotics.
连续排放和抗生素在水生生态系统中的持续存在被认为是新出现的环境健康危害。部分降解和不当处理会诱导出各种抗生素抗性基因（ARGs）和细菌，因此必须加以控制。传统方法，包括废水处理厂（WWTPs），被发现对去除顽固抗生素无效。因此，已经讨论了从环境基质中建设性地去除抗生素和其他替代方法。本综述总结了目前从环境中去除微污染物和抗生素的情况。各种策略，包括物理化学、生物修复、使用生物反应器和生物催化剂，被认为是有效的抗生素去除策略。由于成本低、能源效率高和环境友好性，微生物燃料电池（MFCs）和生物炭已成为有前途的生物降解过程。结合/混合工艺具有更高的去除率（20-50%），似乎更有利于顽固抗生素的永久和可持续去除。
