| 摘 要： | 采用成都某垃圾填埋场的渗滤液浓缩液,对装填了填埋龄为15年垃圾的垃圾柱开展了回灌实验,研究了回灌负荷、回灌频次、回灌速度以及回灌方式对回灌出水盐分的影响;基于实验结果,利用一种新型的灰色绝对接近关联度分析方法进行建模,研究了回灌出水盐分对各参数的敏感性。研究结果表明:以0号垃圾柱的回灌出水盐分为基准,回灌出水盐分对回灌参数的敏感性大小为:回灌负荷(6 L/d)>回灌速度(24 L/h)>回灌负荷(4.5 L/d)>回灌频次(6次/d)>回灌频次(3次/d)>回灌方式(中央布水)>回灌速度(6 L/h)>回灌方式(分散布水),因此降低回灌出水盐分优先控制的因素为回灌负荷和回灌速度。

| Abstract: | By using leachate concentrate from a refuse landfill in Chengdu，the recirculation experiments were carried out inlandfill columns filled with garbage of 15 landfill ages． The influences on recirculation effluent salinity of the recirculationload，frequency，velocity and mode were researched． Based on the experimental results，modeling with a novel grey absolutelycorrelation degree analysis method， the sensitivity effluent salinity from the leachate concentrate recirculation process torecirculation 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 waterdistribution) ＞ velocity( 6 L/h) ＞ mode( dispersing water) ． So the recirculation load and velocity are priority control factors forreducing the salinity of recirculation effluent． |
