  1. 面对中国沼气工程发展，我们该做什么：政策、技术和管理 WHAT WE COULD DO FOR BIOGAS DEVELOPMENT IN CHINA :POLICY, TECHNOLOGIES AND OPERATION 董仁杰 DONG Renjie 中国农业大学教授，国际合作与交流处处长 生物质工程中心常务副主任，工学院能源工程与低碳技术研究室主任 Director of International Relations, Professor and Executive Director of Biomass Engineering Center, Head of BioEnergy Engineering and Low Carbon Technology, China Agriculture University

  2. 主要内容 CONTENT • 沼气工程存在和发展的必然 • 目前沼气工程的问题：现象 • 政策 • 原料 • 沼气工程设备与过程控制 • 沼液和沼渣 • 市场培育与良性竞争 • 中国农业大学与生物质工程中心 • Why Biogas Plants? • The problems we can see • Policies • Feedstocks • Equipment and process control • Digestates • Win-win competition inthe market • China Agricultural University and Its Biomass Engineering Center DLG Forum

  3. 沼气工程存在和发展的必然WHY BIOGAS PLANTS 有机废弃物量大、面广；有些很集中 环保与能源：互为原因，或者此消彼长 Organic Wastes: huge, distributed, sometimes centralized Env. Vs Enr. Need to be arefully handled DLG Forum

  4. 黄和 Prof. HUANG He 国家高度重视沼气工程BIOGAS GREATLY SUPPORTED President Jiang. Yellow River 1958.4 Chairman Mao Zedong.Wuhan, Hubei Province President Hu, Henan Province 1980.7 Leader Deng Xiaoping. Sichuan Province DLG Forum

  5. 沼气工程面临的问题：现象BIOGAS: EFFICIENCY (-), BENEFIT (?) DLG Forum

  6. 沼渣沼液处理 Digestate Treatment 沼气净化储存输送 Biogas Cleaning, Storage, Distribution 预处理单元 Pretreatment 厌氧消化单元 AD 沼气利用单元 Biogas Utilization 沼气工程的基本组成MAIN COMPONENTS OF ONE BIOGAS PLANT Quoted from Tianren Company presentation made by its President Dr. CAO Man DLG Forum

  7. 政策的关键作用CRUCIAL ROLE OF POLICIES 中国：政府主导型 政府制定政策（宏观） 重视建设 难以重视管理与运行效果 通过建设沼气工程盈利 China: Derived by governments Policies but in general Supporting construction Difficult to monitor and evaluate Earning money from biogas construction 欧洲：政府通过市场驱动加以主导 政府制定政策（宏观与可操作性） 建设成果 运行与成果接受市场评价 通过运行沼气工程盈利 EU: Derived by governments through market tools Policies can be referred to by farmers Supporting construction and management Evaluated by market; well tech Make benefit from management DLG Forum

  8. 原料FEEDSTOCKS 畜禽粪便 作物秸秆 农产品加工废弃物 餐厨垃圾 城镇有机废弃物 污水处理厂污泥 联合发酵/混合发酵 Livestock manure Crop residues Organic residues from processing Kitchen waste Organic waste from cities Wastewater treatment sludge Co-fermentation/mixture fermentation DLG Forum

  9. 沼气工程设备与过程控制EQUIPMENT AND PROCESS CONTROL 粉碎等原料预处理 搅拌 加温与保温 监测 农田施用 。。。。。。 Grinding/breaking Sturing/mixing Heating/insolation Monitoring Field application of digestates …… DLG Forum
