干法沼气池厌氧发酵反应器及过程控制技术研究进展
时间 : 2019-03-30 浏览量 : 54


我国年产农作物秸秆约10.4亿吨,20%未有效利用,畜禽粪污约38亿吨,40%以上未有效利用,尾菜约2.3亿吨,大部分未有效利用,严重威胁我国农业农村环境。沼气池厌氧发酵是处理农业废弃物的重要技术路径。农业废弃物经过沼气池厌氧发酵处理后产生的发酵剩余物可用于生产有机肥料,同时产生的沼气燃烧后生成中性碳,是一种重要的清洁能源。水是沼气池厌氧发酵过程的关键控制因素,直接影响沼气池厌氧发酵微生物的活性和关键中间产物的传质过程。根据沼气池厌氧发酵过程中物料的含固率(TS),可将沼气池厌氧发酵分为干法沼气池厌氧发酵和湿法沼气池厌氧发酵。一般而言,物料IS大于15%可认为沼气池厌氧发酵过程为干发酵,反之则为湿发酵2。

近年来,随着我国规模化养殖水平的提高,以畜禽粪便为主要原料的沼气工程彩经网的建设规模也随之增大。当前,全混式的湿法发酵工艺在我国大中型沼
