Abstract: Landfill is the main application technology of rural domestic waste treatment in China. Based on the field survey of 15 small-scale landfills. The problems existed in most small-scale landfills in China were analyzed,and the characteristics of rural application miniaturization of landfill technology were clarified. The research showed that in terms of technology, the miniaturization of landfill technology currently had the practical problem of generally low construction and operation and maintenance level. In terms of economy, small-scale landfills that met the requirements of current standards had poor scale efficiency and high secondary pollution control costs. In terms of carbon emission, the existed small-scale landfills had high carbon emission intensity, so it was necessary to achieve the goal of reducing pollution and carbon by regulating the collection of landfill gas or reducing the direct landfill of primary waste. At the same time, the applicable areas of landfill technology in rural areas and relevant suggestions were put forward on this basis.
