大丰市海丰奶牛场沼气发电工程可研报告 杭州能源环境工程有限公司
第1章 概述
1.1项目摘要
1.1.1项目名称
大丰市海丰奶牛场沼气发电工程 1.1.2项目建设单位
大丰市海丰生物燃气发电有限公司 1.1.3项目拟建地点
江苏省大丰市上海牛奶集团（大丰）海丰奶牛场 1.1.4建设目标
通过热电肥联产沼气工程的建设，处理海丰奶牛场10,000头奶牛的粪污，生产清洁能源，减少奶牛场环境污染，减排温室气体。厌氧发酵每天生产沼气10,800 m3，沼气用于发电，日发电21,600 kW·h，电力上网出售，发酵后的沼液、沼渣作为优质有机肥料用于周边饲料地、果园。既开发了生物质能源，有效利用了资源，又改善了环境，实现养殖业的可持续发展。 1.1.5建设期限
2009年7月—2010年6月 1.1.6项目工艺技术方案
该项目在工艺选择和方案设计中，采用热电肥联产模式和高浓度全混合（CSTR）中温厌氧工艺。项目所生产的沼气全部用来发电，并入电网销售；利用发电机余热为厌氧反应器供热；厌氧发酵后的发酵液经过固液分离，沼渣用来生产固态有机肥，沼液用于奶牛场周围饲料地和果园的有机肥料；在非用肥季节，沼液进入氧化塘净化处理达到畜禽废水排放标准后排放。
