The biocell approach for energy recovery and environmental protection

填埋场作为厌氧生物反应器运作，再加上渗滤液的再循环，将通过增加水分、营养物和细菌的循环，最大限度地增加甲烷的产量，从而使甲烷的回收和转化为能源经济合算。Biocell方法通过允许回收空间和资源以及通过在厌氧生物反应器模式中操作废电池之后接着在有氧模式中操作来进行采矿来保证进一步的进步。虽然Biocell是传统填埋的一种有吸引力的替代方案，但一些技术问题阻碍了加拿大采用这种技术。解决其中一些问题是该项目的重点。在过去的三年里，利用NSREC战略赠款的资金，我们设法解决了两个问题，即：在薄的中间生物覆盖层中使用甲烷氧化菌来控制废物填充过程中的气体排放，以及废物沉降/废物降解之间的相互关系。当前

The operation of landfills as anaerobic bioreactors, with recirculation of leachate, would maximize CH4 production by increasing moisture, and cycling of nutrients and bacteria, thereby making CH4 recovery and conversion to energy economical. The Biocell approach promises further advances by allowing recovery of space and resources as well, by mining after operating the waste cell in the anaerobic bioreactor mode followed by operating in the aerobic mode. Although a Biocell is an attractive alternative to conventional landfilling, several technical issues prevent adoption of this technology in Canada. Resolution of some of these issues is the focus of the project. Over the last three years, using funds from a NSREC strategic grant, we managed to address two issues, namely: use of methanotrophs in thin intermediate biocover layers to control gaseous emissions during waste filling, and interrelation between waste settlement/waste degradation.
