Description

Technical Field

[0001] The utility model relates to the technical field of sludge thickening tanks, in particular to an integrated high-efficiency sludge thickening tank. Background Art

[0002] Sludge thickening tank is a structure used for sludge thickening. It is generally in the shape of vertical flow or radial flow. It can be divided into two types: intermittent operation and continuous operation. The former is mainly used in small sewage treatment plants or sewage treatment plants of industrial enterprises, and the latter is used in large and medium-sized sewage treatment plants. The main feature of the sludge thickening tank is to add a certain amount of flocculant to the sludge to be concentrated, so that the sludge forms flocs and accelerates its sedimentation rate, thereby achieving the purpose of improving the concentration efficiency. In the process of adding flocculants, it cannot be evenly added to the sludge thickening tank, which is easy to affect the mixing effect of flocculants and sludge. The effect of scraping sludge in the sludge thickening tank is still not ideal. There will still be some concentrated sludge at the bottom of the thickening tank. In the process of sludge discharge, the sludge is easy to block the discharge pipe. For this reason, we proposed an integrated high-efficiency sludge thickening tank. Utility Model Content
