摘　　要：总结分析了沼气工程相关技术现状和技术需求,并对其未来发展进行了展望。我国的原料收贮和预处理技术亟待升级,仍需大量的科研投入以研发关键的核心技术装备。实现沼气工程运行情况的有效监测和及时预警,以及开发合适的微量元素添加剂和功能微生物菌剂对推动我国沼气工程的高效稳定运行具有重要意义。试验并研发新型膜材料和对常规材料的共混与改性处理是提高沼气膜分离提纯能力的主要手段。沼液的资源化利用技术是摆脱沼气工程可持续发展瓶颈的关键。结合沼气工程产业发展需求,充分论证技术瓶颈,合理配置科技资源,加大科技攻关投入,实现自主化技术研发、标准化工程设计、工厂化装备制造、模块化安装建设以及专业化安装调试等标准化集成,同时创新沼气工程技术的应用模式能更好地推动沼气工程技术的发展。Current situation of biogas engineering technology was overviewed and its development prospect were analyzed. Generally,with the growing popularity in China,biogas engineering technology has made great progress. The technology for collection,storage and pretreatment of raw materials need urgent upgrading. More and more researches are required to develop key technology and equipment. It is significant for the efficient and stable operation of biogas project to realize effective monitoring and timely warning and develop appropriate trace element additives and functional microbial agents. Testing and development of new membrane materials and blending or modification of conventional materials were the primary means to improve the separation and purification capabilities of bio-methane from biogas. The resourceful utilization of biogas slurry is the key steps for the sustainable development of biogas engineering. Further development of biogas technology claims to realize the standardized integration of independent research and development,standardized engineering design,industrialized production of equipment,modular construction and installation,and professional installation and debugging along with full argumentation of technical bottleneck,rational allocation of resources of science and technology,and increased investment in scientific problem tackling based on the demand of biogas engineering industry development,besides,innovating the application mode of biogas engineering technology is also important and helpful. This paper can provide certain reference for biogas industry practioners and related researchers.
