The invention discloses a microorganism and PRB combined remediation system and application thereof in in-situ remediation of underground water polluted by antibiotics. The microorganism combined PRB remediation system is of a three-layer structure, the modified kaolin-biochar active filler layer and the modified biochar filler layer are arranged on the two sides, the microorganism filler layer is arranged on the middle layer, and the system can achieve efficient adsorption and degradation of antibiotics in underground water to enable the underground water to reach the underground water remediation standard, can prevent blockage, and has the advantages of being long in service life, low in cost and the like. The continuous degradation of pollutants such as antibiotics in underground water can be realized, and the method has a very wide application prospect. 本发明公开了一种微生物联合PRB修复系统及其在原位修复抗生素污染地下水中的应用。微生物联合PRB修复系统具有三层结构，两侧分别为改性高岭土-生物炭活性填料层和改性生物炭填料层，中间层为微生物填料层，该系统能够实现地下水中的抗生素高效吸附和降解，使其达到地下水修复标准，且能够防堵塞，具有使用年限长，耐久性好等
