沼气供应技术研究现状

中国城乡巨大的有机废物废水蕴藏着可观的资源，废物消化得到的一系列产物即沼气、沼渣和沼液均有可能产生巨大的经济效益。沼气作为可再生的绿色燃料，目前已在供热、热电联产、车用燃料、并入天然气管道等方面展现出良好的应用前景。了解国内外沼气供应技术的发展水平，总结先进技术经验，同时结合我国实际情况，着重介绍沼气并网发展模式，研究沼气掺混工艺、设备及相关技术规定，使沼气成为天然气消费缺口的补充，可以此推进城乡统筹和低碳循环经济。

Research Status of Biogas Supply Technology

The enormously organic waste and sewage of urban and rural in China contain considerable resources, a series of product from waste digestion （biogas, biogas residue and slurry） will produce the respectable economic benefits. As a renewable green fuel, biogas has shown a good prospect in heating supply, thermoelectricity cogeneration, vehicle fuel, injection into the natural gas pipeline and other aspects. Keep abreast of the development of biogas supply technology at home and abroad, summarize experience in advanced technology, moreover, combined with the actual situation in China, introduce the development pattern of biogas injection, and discuss mixing technologies, equipments and related technological regulations to make biogas become the supplementary of natural gas consumption gap, and the propellant to coordinating urban and rural construction and circular low carbon economy.
