| 摘 要： | 渗滤液的回灌可以加速填埋场的稳定化 ,降低渗滤液的有机物浓度 .但填埋初期进行渗滤液的直接回灌 ,会导致垃圾层内有机酸的积累 ,阻碍甲烷化过程的建立 .通过实验室模拟 ,研究了垃圾层中空气状况对填埋初期渗滤液直接回灌出水水质的影响 .研究结果表明 :向填埋层供给少量空气 ,就可以解决填埋初期渗滤液直接回灌产生的有机酸积累问题 ,使渗滤液中的有机物迅速降解 .

| Abstract: | Leachate re-circulation can both accelerate landfill stabilization and reduce leachate is done pollution.But when re-circulating initial leachate is done directly,it will cause the accumulation of organic acid and restrain the establishment of methanogenesis.Lysimeters were used in the laboratory to study the impacts on the leachate quality of re-circulating initial leachate under different air conditions in landfill layer.The results indicate that if only ventilating less air,the accumulation of organic acid caused by direct re-circulating initial leachate can be abated.The organic pollution in leachate is greatly reduced. |
