摘　　要：温度对填埋场有机垃圾的厌氧降解具有十分重要的影响,因而对填埋场渗滤液特征也产生重要的影响。文章通过在常温及29-45℃范围内设置的6个不同温度下的模拟垃圾柱降解对照试验,分析研究了温度对填埋有机垃圾渗滤液特征的影响。结果表明,在垃圾降解适宜的温度范围（29-45℃）内,较高的温度对渗滤液COD衰减具有较大的促进作用,而保持恒定的温度比升高温度对渗滤液COD衰减的影响更加显著,但温度对垃圾降解渗滤液中氨氮影响并不明显。The impact of the temperature on the anaerobic degradation of organic refuse is very important, so is on the characteristics of leachate in landfill. Based on the experiment of simulation Refuse Column with six different temperatures set up at room temperature and 29-45 ℃ range, this paper analyzed the impact of temperature on the characteristics of ieachate in landfill. The results showed that in the suitable temperature range （29-45 ℃）, the higher temperature plays a greater role in COD attenuation and the steady temperature plays more notable impact on the attenuation of COD than the high temperature. However, the impact of the temperature on the ammonia in the COD attenuation is not obvious.
