集约化猪场粪污处理工艺的研究

摘要: 根据我国集约化猪场排粪方式和粪水的特性,提出了采用人工清粪方式 、固液分离机+沉淀+UASB+SBR+水生植物塘的污水处理工艺和猪粪(渣)堆沤发酵生产有机 肥新的粪污处理工艺。经上海市嘉定种畜场污水处理工程实践证明:在保证污水全面达标排 放和猪粪(渣)无害化处理的前提下,新工艺比常规工艺节约工程投资35%、节约运行电费6 5%左右,经济效益好 Abstract: In accordance with the characteristics of swine manure-discha rging way and the property of swine wastewater on intensive scaled swine farms i n China, a new technology of swine wastewater treatment and swine manure ferment ation to produce organic fertilizer was presented. This technology includes clea ning manure by manpower, solid-liquid separator+sedimentation basin+Upper-flow Anaerobic Sewage Bed(UASB)+SBR+aquatic plant pond. The project practice of swin e wastewater treatment in Shan ghai Jiading Breeder Farm showed that the new technology could save 35% of the p roject investment, 65% of the operating electricity charges with good direct eco nomic benefit, on condition of guaranteeing the prerequisites that the discharge d swine wastewater reached the state standard all-sidedly and swine manure was pollutionlessly treated. 作 者: 李长生    王应宽    LI Changsheng    Wang Yingkuan   作者单位: 中国农业工程设计研究院,  期 刊: 农业工程学报  ISTICEIPKU   Journal: TRANSACTIONS OF THE CHINESE SOCIETY OF AGRICULTURAL ENGINEERING  年,卷(期): 2001, 17(1)  分类号: X713  关键词: 猪粪处理    固液分离    沉淀    厌氧池    好氧池    堆沤发酵
