摘要
试验研究了矿化垃圾细料与土壤作为生物反应床填料处理渗滤液效果的差异,以及加管通风条件对矿化垃圾柱和土壤柱处理渗滤液效果的影响.结果表明:矿化垃圾细料对渗滤液中CODCr和NH4+-N的去除效果明显好于土壤.在水力负荷为40L/(m3.d)和布水时间为2.0h的条件下,矿化垃圾细料对渗滤液中的CODCr和NH4+-N有良好的去除效果,去除率分别达73%和66%;而土壤对CODCr和NH4+-N的去除率分别只有52%和42%;加管通风条件使矿化垃圾对渗滤液的处理效果明显提高,对COD和NH+-N的去除率分别提高了9%和26%.
Aged refuse and soil were used as stuffing of a bioreactor to investigate their difference in disposal of waste leachate and the effect of aeration on disposal. The results showed that CODCr and NH4^＋ -N of waste leaehate can he more effectively removed by an aged refuse bioreactor than by a soil bioreaetor. Under the conditions of distributing water 40 L/（m^3·d） and time 2.0 h, 73% of CODCr and 66% of NH4^＋ -N in leachate were removed by the aged refuse bioreactor, while only 52% of CODcr and 42% of NH4^ ＋ -N were removed by the soil bioreaetor. Furthermore, disposal of waste leachate can be improved by aeration in an aged refuse bioreactor; removal of CODCr and NH4 ^＋ -N increased by 9 % and 26 % , respectively.
