2011国际沼气技术与环境工程学术研讨会暨产业化论坛论文集23中国农村沼气持续发展的技术对策邱凌(西北农林科技大学农业部沼气产品质检西北站,陕西杨凌712100)摘要:中国农村沼气建设数量不断扩大,投资结构不断优化,服务体系逐步健全,沼气功能进一步拓展,沼气产业迅速发展,取得了显著成效。农村沼气董大面广,是多学科交叉、需要“精确设计、精准建设、精细管理”的系统工程。目前存在的主要问题是:系统缺乏精确设计和科学配套,建设质量缺乏监管和竣工检验,沼气启动缺乏合理配料和指导,日常管理缺乏长效的服务机制,技术和管理人员缺乏专业培训。持续发展和长效运行的技术对策为:精确设计科学配套,精准建设确保质童,吐故纳新增强动力,整体保温提髙效率,动态发酵精细管理,广开料源混料制气,综合利用长效发展,科技支撑引领发展。关键词:农村沼气;发展现状;存在问题;技术对策ProblemsofSutainableDevelopmentofrural-biogasinchinaandtechnologycountenneasore/QiuLing/(NorthwestA&FUniyersityNorthweststationofbiogascenterMOA,YangLing712100)Abstract:rural-biogasinchinahasgainhugeachievement,ranging&omincreasingofquantity,optimizingofinvestmentstructure,improvementofservicesystem,expandingoffunctionofbiogasandboomingofbiogasindustry.Rural-biogashavealargeamountandawiderange,is&systematicengineeringcombinebymanysubjects,needMdesign,constructandmanagementpreciously^.problemsweconfrontednowadaysincludes:lackofaccuratedesignandscientificmatingonbio?gassystem,lackofsuperviseandtestoncompletiononconstructionquality,lackofreasonablematchingofrawmaterialsandinstructiononlaunchofbiogassystem,lackofdurableservicesystemondairymanagementandlackofprofessionaltrainingontechnicistandmanager,technologycountermeasureforSutainableDevelopmentandlong-termrunningofbio?gassystemis:accuratedesignandscientificmatingonbiogassystem,preciousconstructiontoensurethequalityofbiogassystem,exhaletheoldmaterialsandinhalethenewmaterialstimely,preservetheheatonthewholetoincreaseeficient,dy?namicfermentationandaccuratemanagement,comprehensiveutilizationandscienceandtechnologysupport.Keywords:rural-biogas,devebpment,existingproblemstechnologycountennaasurei发展现状经过多年的建设与发展,中国农村沼气已经成为现代循环农业的核心和纽带,形成了北方“四位一体”、南方“猪-沼-果”和西北“五配套”等经典循环农业模式。发展农村沼气对于促进农业增产,农民增收,提髙农民生活水平,改善生态环境,推
