摘要
为进一步验证准好氧填埋技术的实用性,在成都市长安垃圾填埋场内进行了三个规模均为10 m×10 m×5 m的准好氧填埋单元试验研究,并分别对渗滤液的pH值、VFA、COD、BOD5和NH4+-N进行了分析。结果表明:对渗滤液中COD、BOD5的降解效果均较好,在分别经过742、704、697 d后,三个单元对COD的去除率分别达到了94.0%、98.0%和96.9%,对BOD5的去除率分别达到了99.4%、99.7%和99.6%;由于受到渗滤液收集管管径较小的限制,对NH4+-N的降解效果较差,因此需要根据准好氧填埋场的规模来调整渗滤液收集管的管径。
In order to further study the applicability of semi-aerobic landfill, three large-scale semi-aerobic landfill units （10 m × 10 m × 5 m） were constructed at the Chang＇ an Landfill Site of Chengdu City. The pH, VFA, COD, BOD5 and NH4^＋ - N of the leachate were analyzed. The results show that the degradation of COD and BOD5 is effective. After 742,704 and 697 days, the COD removal rate of the three landfill units is 94.0% , 98.0% and 96.9% ; the removal rate of BOD5 is 99.4%, 99.7% and 99.6% respectively. However, the degradation effect of NH4^＋ - N is not apparent because of small diameter of the collection pipe. Thus, the diameter of collection pipe should be adjusted according to the scale of landfill site.
