养猪污染治理异位微生物发酵床的设计与应用

摘要

异位微生物发酵床是集中处理养猪废弃物的场所,通常建设在传统猪舍的周围.发酵床内铺设垫料,将猪舍的排泄物引导到异位微生物发酵床内,通过翻堆机将排泄物与发酵垫料混合,进行发酵,消纳粪污,消除臭味,实现零排放,生产有机肥.本课题组设计了一种新型异位微生物发酵床,由钢构房、喷淋池和发酵池0组成,并配备翻堆机、喷淋机等设备.异位发酵床可适用于各种传统养猪方法的污染治理,具有较高的生态、经济、社会效益.%Remote fermentation beds are usually built not in but nearby the piggeries to serve as centralized waste treatment facility.A newly designed and built fermentation bed utilized plant wastes to receive and mechanically mix with pig excrement for microbial fermentation to result in an organic fertilizer.The facility consisted of a steel framed structure,a pool and a fermentation tank with accessories such as aerator,sprayer and others.The economical,ecological and social advantages with superior effluent control of the new design over the conventional settings for pig farm operations were illustrated.
