使用部分预水合石灰分离固体物质/液体混合物，通过所述方法得到的处理污泥和净化污泥的方法

Use of partly prehydrated lime for separating a solid matter/liquid mixture, method for treating sludge and purified sludge obtained by said method
Abstract:
A novel use of delayed reactivity partly prehydrated lime (“DRQL”), which is comprised of 40 to 98% by weight of CaO and of 60 to 2% by weight of Ca(OH)2, preferably of 80 to 92% by weight of CaO and of 20 to 8% by weight of Ca(OH)2, and more preferably of 85 to 90% by weight of CaO and of 15 to 10% by weight of Ca(OH)2, in the field of the separation of solid matter from the liquid of a suspension. The invention also involves a novel method for treating a sludge, in which the solid matter is concentrated, dried and recovered using the delayed reactivity partly prehydrated lime. It additionally relates to, as a novel industrial product, the purified sludge obtained according to the method.
Abstract(Chinese):

由40至98重量％的CaO和60至2重量％的Ca（OH）2，优选80至92重量％的重量组成的延迟反应性部分预水合石灰（“DRQL”）的新颖用途 的CaO和20〜8重量％的Ca（OH）2，更优选为85〜90重量％的CaO和15〜10重量％的Ca（OH）2，在分离领域 的固体物质来自悬浮液的液体。 本发明还涉及一种处理污泥的新方法，其中固体物质被浓缩，干燥并使用延迟反应性部分预水合石灰回收。 另外，作为新型工业品，另外涉及根据该方法获得的纯化污泥。
