摘要： Paunch-sludge from an abattoir is mixed with the fatty DAF-float from an abattoir, and placed in a shearing vessel. The mixture of the two material thickens the medium in which the matted strands are contained, enabling shearing to be more effective; so much so that paunch-sludge can now be sheared to a homogeneous liquid. The technique can be used with other sludges and other fatty waste materials.

摘要： Hydrophobic contaminants are removed from sludge that has been liquidized by violent shearing, by stirring a hydrophobic sorbent substance material into the sludge. After a period of time in which the contaminants are sorbed into the sorbent, the sorbent substance is separated from the sludge by gravity-settling, centrifuging, etc, where the sorbent is a liquid, or by filtration etc where the sorbent is a solid. Some sorbents have a melting point such that the sorbent can be liquid for good dispersal in heated sludge, and then can be solid when the sludge has cooled, whereby the sorbent can be removed e.g by filtration. Liquefaction by violent shearing causes the biosolids in the sludge to go into solution, which leaves the hydrophobic contaminants more available to be sorbed.
摘要翻译： 通过将疏水性吸附剂物质材料搅拌到污泥中，从通过剧烈剪切液化的污泥中除去疏水污染物。 在污染物吸入吸附剂的一段时间之后，通过重力沉降，离心等将吸附剂物质与吸附剂物质分离，其中吸附剂是液体，或通过过滤等吸附剂是固体。 一些吸附剂具有熔点，使得吸附剂可以是液体的，用于在加热的污泥中良好分散，然后当污泥已经冷却时可以是固体，从而可以通过过滤除去吸附剂。 通过剧烈剪切的液化使污泥中的生物固体进入溶液中，这使得疏水性污染物更易于吸附。

摘要： Already-treated sludge is fed back into incoming sewage, and is effective to supply nutrients needed for the microbiological breakdown of the sludge. The feedback sludge has a solids content of 10% or more, and has been sheared and heated to drive its viscosity down to 10,000 cP or less. In sludge done that way, nutrients are preserved and presented to the sewage to be treated in highly liquidised and solubilised form, whereby the nutrients are very bio-available to the microbes in the sewage. Large improvements in the elimination of biomass can result.
摘要翻译： 已经处理的污泥被回收进入污水，有效提供污泥微生物分解所需的营养物质。 反馈污泥的固体含量为10％以上，经过剪切加热，使其粘度降至10000cP以下。 在这样做的污泥中，营养物质被保存并提供给待处理的污水，并以高度液化和溶解的形式进行处理，从而营养物质对生物污水中的微生物非常有效。 可以大大改善生物质的消除。

摘要： When liquefying sludge, e.g as in U.S. Pat. No. 6,808,636, the combination of temperature, pH, and shearing, is synergistic. Described here is a system that provides for collating test sampling and full-scale data inputs, recording achieved results and the engineering parameters that achieved those particular results. The data is presented in e.g a table format, which assists design engineers to zero-in on the combinations of parameters that will likely give the desired results.
摘要翻译： 当液化泥浆时，例如在美国专利No. No.6,808,636，温度，pH和剪切的组合是协同的。 这里描述了一种系统，用于整理测试采样和全尺寸数据输入，记录实现的结果以及实现这些特定结果的工程参数。 数据以例如表格格式呈现，这有助于设计工程师对可能给出期望结果的参数组合进行归零。

摘要： Sewage sludge that has been de-watered to 25% solids is subjected to a combination of shearing and heating that liquefies the sludge, and drops its viscosity to below 12,000 cP. The fact of liquefaction prepares the sludge such that subsequent drying can be done more cost-effectively than hitherto. After drying, the dried sludge can be incinerated.
摘要翻译： 已经脱水至25％固体的污水污泥经受剪切和加热的组合，使污泥液化，并将其粘度降至12000cP以下。 液化的事实准备了污泥，使得随后的干燥可以比迄今为止更具成本效益地进行。 干燥后，干燥的污泥可以被焚烧。
