摘要
结合深圳市盐田区垃圾场处置工程，对主场近期堆放的垃圾进行了基本特性的分析研究．结果表明，盐田区表层垃圾组分以有机成分为主，热值较高．渗沥液中的有机污染物含量超过允许排放浓度．主垃圾场的下层垃圾已进入厌氧发酵阶段，填埋气体中甲烷浓度达５０％以上，对垃圾场处置工程的施工安全具有潜在的威胁．
An analysis of basic features has been made for the waste in the Yantian waste landfill site of Shenzhen city. The results show that the waste contains a great organic component part and has a high calorific value.The content of organic pollutants in leaching liquor is over the permissible value.The measures of landfill gas (LFG) show that the degradable organic waste has gotten into the anaerobic digestion, the content of methane is more than 50%,and LFG is a potentially danger for the disposal of the wastes in the landfill site.
