集约化猪场粪污处理工艺的研究(英文)

    Technology of Swine Manure Treatment on Intensive Scaled Swine Farms

    • 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65%左右,经济效益好。

       

      Abstract: In accordance with the characteristics of swine manure-discharging way and the property of swine wastewater on intensive scaled swine farms in China, a new technology of swine wastewater treatment and swine manure fermentation to produce organic fertilizer was presented. This technology includes cleaning manure by manpower, solid-liquid separator+sedimentation basin+Upper-flow Anaerobic Sewage Bed(UASB)+SBR+aquatic plant pond. The project practice of swine wastewater treatment in Shanghai Jiading Breeder Farm showed that the new technology could save 35% of the project investment, 65% of the operating electricity charges with good direct economic benefit, on condition of guaranteeing the prerequisites that the discharged swine wastewater reached the state standard all-sidedly and swine manure was pollutionlessly treated.
