Influences of Leachate Property on Pollutants Attenuation in Aquifer
渗滤液性质对含水层中污染物衰减的影响研究

Simulated columns filled with fine sand were conducted to investigate influences of leachate properties on pollutants attenuation and bacterial activity in aquifer.Experimental results indicated that bacterial activity of young landfill leachate,aged landfill leachate and rain water through columns was up to maximum 0.154,0.121 and 0.044 in 12 d,17 d and 3 d,respectively;the maximum BOD_5/COD was up to 0.683,0.396 and 0.319 in 12 d,8 d and 6 d,respectively,and the averaged increasing rate of pH was up to 0....
