Abstract
(EN)
The present invention relates to a multistage separation reaction tank for treating sewage sludge by forming a collection layer, a diffusion layer, a primary buffer layer, a secondary buffer layer, and an inorganic precipitate layer when treating an organic material by adding a liquid solvent having a specific gravity less than water to the sewage sludge. In addition, the present invention relates to a method for treating sewage sludge by using an alkane-based solvent, wherein the method significantly lowers the water content of the sewage sludge by using an alkane-based solvent which is in a liquid state and non-polar at atmospheric pressure and room temperature.

La présente invention concerne un réservoir de réaction de séparation à étages multiples pour traiter des boues d'épuration par formation d'une couche de collecte, d'une couche de diffusion, d'une couche tampon primaire, une couche tampon secondaire et d'une couche de précipité inorganique lors du traitement d'un matériau organique par ajout d'un solvant liquide ayant un poids spécifique inférieur à celui de l'eau pour les boues d'épuration. De plus, la présente invention concerne un procédé de traitement de boues d'épuration à l'aide d'un solvant à base d'alcanes, le procédé abaissant significativement la teneur en eau des boues d'épuration à l'aide d'un solvant à base d'alcane qui est à l'état liquide et non polaire à la pression atmosphérique et à la température ambiante.

본 발명은 하수 슬러지에 물보다 비중이 작은 액상 용매를 투입하여 유기물을 처리시 포집층, 확산층, 1차 완충층, 2차 완충층 및 무기물 침전층을 형성하여 하수 슬러지를 처리하는 다단 분리 반응조에 관한 것이다. 또한, 본 발명은 대기압, 상온 하에서 액체 상태이고 비극성인 알케인 계열 용매를 이용하여 하수 슬러지의 함수율을 월등히 낮추는 알케인 계열 용매를 이용한 하수 슬러지 처리 방법에 관한 것이다.
