摘要
通过2套间歇式生物反应器填埋模拟装置开展实验,对不同填埋结构下垃圾降解前期渗滤液pH值、COD、NH 4+-N、VFA以及渗滤液产生量的变化规律进行了对比研究。实验结果表明:间歇式生物反应器填埋方式能够有效抑制填埋初期渗滤液pH值的快速下降,渗滤液采取部分回灌能有效降低NH4+-N浓度的积累,新鲜垃圾与半腐熟垃圾分层并以1∶1的质量比填埋能够显著改善渗滤液的水质。
Based on experiments with 2 sets of apparatuses of batch type bioreactor simulating landfill,changes of pH,COD,NH＋4-N,VFA and production of the leachate in the early period of landfill MSW（municipal solid wastes） degradation were studied by comparison of laboratory simulations with different landfill structures.The results showed that the landfill mode of batch type bioreactor could inhibit the rapid decline of the initial pH value of leachate;the recirculation of partial leachate could lead to accumulation of the NH＋4-N concentration reducing effectively;and fresh waste and semi-decomposed waste layering landfill at the ratio of 1∶1 could improve the quality of leachate significantly.
