摘要
垃圾填埋场产生大量渗滤液,而一般厌氧型填埋场产生渗滤液中含有很高浓度的有机物。因此,渗滤液成为填埋场的难题。通过试验模拟垃圾的好氧填埋过程,并在此过程中对垃圾产生渗滤液中的COD、BOD5和NH 4+-N进行连续监测,通过试验初步得出:在好氧填埋条件下,垃圾堆体产生渗滤液中有机物和NH 4+-N浓度得到较大程度降低。渗滤液中COD、BOD5和NH 4+-N的降解率分别高达98.99%、99.94%和99.78%。
Plenty of leachate can be produced from landfill sites,which includes highly concentrated organics.Therefore it is difficult to treat the leachate on the landfill site.The process of refuse aerobic landfill was simulated by tests,and COD,BOD5 and NH 4＋-N in the leachate were monitored continuously.It was known by tests that on condition of aerobic landfill,the concentrations of organics and NH 4＋-N were reduced greatly.The degradation rate of COD,BOD5 and NH 4＋-N in the leachate was up to 98.99%,99.94% and 99.78% respectively.
