上海郊区小型沼气发展的前景与方向

文章介绍了上海郊区沼气开发利用的发展历程和现状，分析了上海沼气发展萎缩的原因，指出上海在节能减排的大形势、寻找合理的农村生活垃圾处理出路和解决小型禽畜养殖场的环境问题等压力下，对郊区的沼气发展产生了新的需求。而以小型养殖场为中心、吸纳农村有机生活垃圾的小型沼气系统则是上海郊区未来沼气发展的方向，也是新农村环境整治的可行途径。

Environmental Solution in New Countryside: Development Prospect and Direction of Small-sized Biogas Projects in Shanghai Rural Areas

The traditional rural area is to some extent a cycle system without pollution. Since the biogas and compost projects decreases, the cycle system has decomposed, the solid wastes and the livestock dejecta became the main causes for non-point pollution and the objects of environ-mental solutions in rural area. But the decreasing of biogas projects doesn't mean the backwardness of biogas technique, the outdated equipments and management contribute a lot as the labor force cost increase. Now there comes out new demand for the development of biogas projects in order to meet the requirements of energy saving and emission reduction as well as to find an appropriate way to deal with the rural solid wastes and the dejecta from the small livestocks breeding farm. As a result, the small biogas system near the small livestocks breeding farm, taking in the rural organic wastes, is a new development of the biogas projects in the suburb of Shanghai for the future, and it is also a feasible environmental solution in Shanghai rural areas.
