填埋期模拟准好氧填埋场的渗滤液水质特征

采用室内试验，模拟填埋期回灌型准好氧填埋场垃圾渗滤液水质变化特征。结果显示，新鲜垃圾的定期填入使渗滤波水质产生明显波动，其主要水质指标（COD、NH3-N等）不存在如非填埋期渗滤液水质指标持续下降的变化规律，表明即使对于回灌型准好氧填埋场，当其已填埋垃圾规模较小时，其处理渗滤液的能力和抵御新填入垃圾干扰的能力均是十分有限的。本研究有助于填埋期垃圾渗滤液的合理回灌。

Water Quality of Leachate from Simulated Quasi-aerobic Landfill during Filling Period

This paper conduct experiments in laboratory adopting simulated leachate to study the change of water quality in recirculation style quasi-aerobic landfill during filling period. The results show that leachate quality fluctuates significantly resulting from the fresh wastes filled regularly. The main water quality index such as COD and NH3-N will not keep dropping as that during filling period. It means that if the scale of wastes filled is small, even though for process of recirculation style quasi- aerobic landfill, the capacity to treat leachate and buffer of accept fresh wastes are quite limited. This study is helpful for reasonable recirculation of leachate during the filling period.
