摘要： A method of treating animal manure yielding a final liquid fraction and solid fractions whereby the final liquid fraction has a suspended solids (SS) content of about 3 g/L or lower comprising subjecting at least a part of said manure to a first biological passive flotation step in a flotation unit having a hydraulic residency time (HRT) of about 4 to about 24 hours with a polymer to yield a first flotation solid fraction and a first flotation liquid fraction, said method comprising a further treatment. An apparatus for treating animal manure comprising a main flotation unit having a HRT of about 4 to about 24 hours, said main flotation units including skimming means for removing floating solids from at least a portion of the surface of the manure and dredging means for removing settled contaminants from at least a portion of the bottom of the tank, whereby at least a part of said manure is directed to the main flotation unit wherein it is separated in a first floating solids fraction, a second liquid fraction and a first settled solids fraction and wherein the second liquid fraction has a SS content of about 3 g/L or lower.
摘要翻译：一种处理动物粪便的方法，其产生最终液体馏分和固体馏分，由此最终液体馏分具有约3g / L或更低的悬浮固体（SS）含量，包括使至少一部分所述肥料进行第一生物被动浮选在聚合物中具有约4至约24小时的水力驻留时间（HRT）的浮选单元的步骤，以产生第一浮选固体部分和第一浮选液体馏分，所述方法包括另外的处理。一种用于处理动物粪便的装置，包括具有约4至约24小时的HRT的主浮选单元，所述主浮选单元包括用于从粪便表面的至少一部分去除漂浮固体的撇渣装置和用于除去沉降的来自罐底部的至少一部分的污染物，其中所述粪便的至少一部分被引导到主浮选单元，其中它在第一浮选固体馏分，第二液体馏分和第一沉淀固体馏分中分离，其中所述第二液体馏分的SS含量为约3g / L或更低。
