摘要
设计3组厌氧生物反应器R1、R2和R3模拟研究日覆盖层对厌氧生物反应器填埋场中氮转化去除的影响。R1为对照,R2和R3日覆盖层分别为"脱水污泥+垃圾焚烧飞灰"、"脱水污泥+天然沸石"。结果表明,"脱水污泥+天然沸石"能加速固相垃圾及其渗滤液中含氮组分的转化去除,而且有利于维持垃圾体含水率;而"脱水污泥+垃圾焚烧飞灰"尽管对厌氧生物反应器中产生的有机酸有缓冲效应,但其对氮转化有一定的抑制作用。实验结束时,R1、R2和R3中垃圾的全氮降解转化率为84.2%、86.6%和88.7%,渗滤液的总氮、氨氮、硝态氮浓度分别为3261mg/L、3372mg/L、2521mg/L,1514.59mg/L、1903.78mg/L、1290.27mg/L,92.17mg/L、95.68mg/L、87.63mg/L。因此,日覆盖层的组成对厌氧生物反应器填埋场中氮的转化有重要影响。
