沈阳市老虎冲垃圾填埋场填埋气产量估算

通过选取3种不同的填埋气预测模型:IPCC模型、中国填埋气估算模型、德国模型,结合沈阳市老虎冲填埋场的实际情况,对各参数进行了修订,从而预测老虎冲填埋场填埋气产量情况,并分析比较各模型预测结果。结果表明,2003—2011年,3种模型反映了相同的填埋气变化趋势,趋于上升状态;2012—2025年,由于填埋量发生变化,IPCC模型与中国填埋气估算模型和德国模型的填埋气变化情况相反,呈下降趋势。3种模型预测的填埋气产量的峰值大小为:中国填埋气估算模型为3.3×107m3/a,IPCC模型为2.1×107m3/a,德国模型为9.8×106m3/a。根据实际产气情况进行对比,发现德国模型更符合实际情况。

The article selected three different kinds of landfill gas（LFG） generation models ：IPCC model, LMOP China model and German model with the practical situation of Shenyang Laohuchong Landfill Site concerned and revised the parameters of these models to predict the situation of Shenyang Laohuchong LFG generation and analyze the results of these models. It shows that three models reflect the same change trend in ascendant condition from 2003 to 2011 ;but because of the quantity changing of landfill waste from 2012 to 2025, the change trend of LFG generation predicted with IPCC model appears in descendant condition, which is in contrast to that of LMOP China model and German model. The order of these models＇ peak value is ： LMOP China model （3.3 × 10^7 m3/a）〉IPCC model （2.1 × 10^7 m3/a）〉German model （9.8 × 10^7 m3/a）. Compared with the practical measurement, the German model is more conform to the actual situation.
