Landfill　leachate　treatment　is　an　emerging　topic　in　the　wastewater　treatment　field.　This　paper　provided　a　review　of　the　landfill　leachate　quality　and　different　treatment　methods,　along　with　a　critical　review　of　current　physico-chemical　and　biological　treatment　techniques.　Biochemical　techniques　are　the　primary　techniques　used　for　leachate　treatment,　while　the　physico-chemical　methods　are　generally　used　for　pretreatment　or　advanced　treatments.　Enhancing　the　biochemical　process　and　improving　the　efficiency　of　nitrogen　removal　from　landfill　leachate　would　be　the　potential　direction　for　future　research　and　industrial　applications.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
