Abstract: The development of biogas power generation technology was introduced. Based on the four determinant indexes which inclutes the total solid, the biochemical oxygen demand, the chemical oxygen demand and volatile solid, combining with the principle of practical fermentation process, the biogas productions of diffirent raw materials were obtained. Aimming at the practical situation of biogas power generation project, the fasibilities of several plans for waste heat utilization of biogas power generation were discussed.

Key words: biogas generation technology, raw material for producing biogas, biogas production, biogas production technology, waste heat utilization
