摘要
为有效利用污泥填埋场内产生的沼气,以上海白龙港污水处理厂污泥为例,对污泥填埋场中气体产生率及产生量进行了预测.应用元素的归一化摩尔化方法得到该污水处理厂污泥有机物的近似分子式为C28H52O16N4.用化学计量法和IPCC模型预测的甲烷气体产生潜能分别为60.6,61.7kg/t(以干重计).用动力学模型和IPCC模型预测的甲烷气体产生率分别为13.3,11.1kg/(t·a)(以干重计),2种方法计算的甲烷气体产生率的差别主要在于参数的取值不同,化学计量法和动力学模型法预测的气体产生量和产生率更能反映污泥填埋场实际的气体产生情况,应用IPCC模型更适合于从宏观角度估算一个地区或整个国家的填埋场产气量.
In order to utilize the sludge landfill gas effectively,production rate and production content of sludge landfill gas were predicted.The approximate formula of sludge organics for Bailonggang wastewater treatment plant in Shanghai was C28H52O16N4 using the normalized molar methods of elements.The potential of methane production predicted using chemometrics method and IPCC model were 60.6,61.7kg/t（dry weight）,respectively.The production rate of methane predicted using dynamics model method and IPCC model method were 13.3,11.1kg/（t a）（dry weight）,respectively.The difference for the methane production rate of these two methods lies in the differences for the values of parameters.The methane production content predicted using chemometrics method and methane production rate predicted using dynamics model method was suit to reflect the actual situation.IPCC model was suitable for estimate the gas production content of a region or country as a whole from a macro perspective.
