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 〖JP3〗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.
