At　present,　there　are　various　methods　to　remove　volatile　organic　compounds(VOCs),　including　physical,　chemical　and　biological　ones.　Among　treatment　methods,　biological　method　has　been　paid　more　attention　because　of　its　advantages　of　fewer　by-products.　However,　the　efficiency　of　biological　method　to　remove　hydrophobic　pollutants　is　low　due　to　the　limitation　of　mass　transfer　and　other　factors,　adding　additives　is　one　of　the　solutions.　In　this　paper,　the　kinds　of　additives　used　in　the　process　and　the　influence　of　additives　on　the　performance　of　bioreactor　were　reviewed,　including　the　effects　on　degradation　efficiency,　biomass,　pressure　drop,　biofilm　and　mineralization　rate.　It　can　be　concluded　that　the　addition　of　additives　has　a　positive　effect　on　the　performance　of　the　bioreactor　in　removing　VOCs,　which　can　improve　the　degradation　efficiency　and　reduce　the　packing　material　clogging　in　the　process　of　operation　to　some　extent.　Additionally,　there　are　few　studies　on　the　effect　of　additives　on　VOCs　degradation　mechanism;　therefore,　the　future　research　direction　of　additives　in　bioreactor　was　prospected.　©　2022,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
