干湿耦合厌氧发酵制气技术在中国生物质沼气产业的应用
APPLICATION OF DRY-WET COUPLED ANAEROBIC FERMENTATION DIGESTION TECHNOLOGY IN CHINA'S BIOMASS BIOGAS INDUSTRY
摘要
Abstract
This paper takes the Hebei Huadian Fengning biomass biogas comprehensive utilization project as an example to elaborates on the application of dry-wet coupled anaerobic fermentation digestion technology,introduces the core process and main construction situation of the project,and analyzes the material balance and implementation significance of the project.The installed power generation capacity of this project is 1.2 MW,using two biogas CHP units with an installed power of 600 kW.It is designed to process 47500 t of livestock waste and 2920 t of crop straw annually,with an annual biogas production of 4.38×106 m3,an annual power generation capacity of 9×106 kWh,and an annual production of 14000 t of solid bio organic fertilizer.By combining garage style dry fermentation and CSTR wet fermentation technology,it can effectively treat accumulated agricultural waste and dynamic livestock manure agricultural waste,and has strong acceptance for different states of anaerobic fermentation materials.As the first application of dry-wet coupled anaerobic fermentation digestion technology in the field of biomass biogas in China,this project can help rural revitalization and improve the living environment,promote green ecological cycles in agriculture and rural areas,and achieve an annual reduction of about 30000 t of CO2 emissions while resourceful treating agricultural waste.This project has good adaptability to agricultural waste raw materials in different states,and achieves zero discharge of system biogas slurry through anaerobic fermentation and internal circulation of biogas slurry.It can provide an innovative agricultural waste resource treatment mode for China's biomass biogas industry.关键词
