摘　　要：本文设计了一套以沼气工程为纽带的矿区土地恢复生态循环系统,城市废弃物通过厌氧消化工艺进行处理。所产生的沼气用作矿区土地恢复园区的生活燃气,多余的沼气用于发电,为恢复园区提供电能;所产生的沼渣制作成固态有机肥,用作园区发展生态农业所需肥料;所产生的沼液制作成液态有机肥,用作园区发展农业所需液肥,多余的液肥通过净化系统净化,用作园区的灌溉用水,实现零排放。园区所种植的有机农产品可供居民食用,从而建立可持续的农业生态循环系统。介绍了系统的设计方案、理论设计及计算方法,并对效益进行了分析,以期为矿区的土地恢复提供参考。This paper designed a set of ecological circulation system for restoration of mining area land based on biogas engineering technology. Through the anaerobic digestion process, the biogas produced by municipal waste could be used as life gas, and redundant biogas could be used for electricity generation. The biogas residue could be used to make solid organic fertilizer for the development of the ecological agriculture. In addition, the biogas slurry could be used to make liquid organic fertilizer, and the redundant liquid fertilizer could be purified through the purification system and used for irrigation water, thus achieved zero emission.The organic agricultural products could serve the residents in this area,to establish a sustainable agricultural ecological circulation system. This paper introduced the design scheme,theoretical design and calculation method of the system,and analyzed the benefits of the system, in order to provide references for the land restoration in the mining area.
