By using leachate concentrate from a refuse landfill in Chengdu，the recirculation experiments were carried out in
landfill columns filled with garbage of 15 landfill ages． The influences on recirculation effluent salinity of the recirculation
load，frequency，velocity and mode were researched． Based on the experimental results，modeling with a novel grey absolutely
correlation degree analysis method， the sensitivity effluent salinity from the leachate concentrate recirculation process to
recirculation parameters were researched． It is showed that the sensitivity of effluent salinity to recirculation parameters were:
load( 6 L/d) ＞ velocity( 24 L/h) ＞ load( 4. 5 L/d) ＞ frequency( 6 times /d) ＞ frequency( 3 times /d) ＞ mode( central water
distribution) ＞ velocity( 6 L/h) ＞ mode( dispersing water) ． So the recirculation load and velocity are priority control factors for
reducing the salinity of recirculation effluent．
