厌氧填埋垃圾降解阶段指标体系的建立

The Establishment of the Index System for Decomposition Phase of Anaerobic Landfill

以厌氧填埋场中垃圾的降解过程为依托点,从渗滤液的水质特征和填埋气的组成两个方面筛选出判断指标,最后建立判断填埋垃圾降解阶段的指标体系。结果表明,ρ(BOD5)/ρ(COD)可以反映出渗滤液的可生化性,从而间接反映出填埋垃圾所处的降解阶段,是判断填埋垃圾降解阶段的重要定量指标。

Based on the biodegradation processes of domestic garbage in anaerobic landfill, the indexes for judgment are chosen from the leachate characteristics and gases composition of their landfilled garbage. Those indexes establish a system for indicating decomposition phase of landfilled domestic garbage. The results show that p （ BOD5 directly, ）/p（COD） indicates biochemical ability of the leachate directly and decay stage of domestic garbage inso it is an important quantity index for judgment of decomposition phase of the landfilled garbage
