Technical Field

The application relates to the technical field of sludge treatment equipment, in particular to a conditioning tank.

Background

Sludge is a product after sewage treatment, and is an extremely complex heterogeneous body consisting of organic debris, bacterial cells, inorganic particles, colloids and the like. The main characteristics of the sludge are high water content and high organic matter content. Therefore, the sludge is easy to be decomposed and smelly in the long-term storage process. Sludge is a thick matter between liquid and solid that can be transported by a pump, but it is difficult to perform solid-liquid separation by settling.

In the related art, the traditional sludge conditioning method comprises the following steps: firstly, sludge to be treated is accumulated in a sludge tank, and then slaked lime is put into the sludge tank, so that bacterial thalli in the sludge are killed, and the sludge is promoted to flocculate.

In view of the above-mentioned related art, the inventor believes that large-particle garbage still exists in the sludge pool after the sludge is conditioned due to the large-particle garbage, and the sludge is still likely to be rotten and smelly as time goes on.
