Description

Interior axial sludge thickener

Technical Field

The utility model relates to the technical field of sewage treatment equipment, in particular to an inner axial flow sludge thickener.

Background

The sewage treatment process can be simply understood as that the pollutants are precipitated out in the form of sludge, so that the sewage is purified. Therefore, a large amount of sludge is generated in the sewage treatment process. The water content of the precipitated sludge is high, and the sludge pumped out by the water pump is basically water. This severely affects the efficiency of sludge treatment. A common way of sludge concentration is a sludge concentration tank, or sludge concentration basin. But the concentration effect is not good. Since the sludge is usually floating on the water surface after fermentation and expansion, the supernatant contains a large amount of sludge, which is returned to the treatment system through the discharged supernatant. The concentration effect is not achieved, but the dead mud of the system is increased. Thereby affecting the sewage treatment effect. And the occupied area of the sludge concentration tank or the sludge concentration tank is larger. The area of the sludge distribution at the bottom is larger, and the concentrated sludge is more difficult to extract. Therefore, if the sludge can be concentrated in the form of equipment, not only a stable concentration effect can be obtained, but also continuous production can be achieved. Meanwhile, the occupied area is small, the controllability is strong, the operability is high, and the efficiency is high, so that the invention of the sludge thickener is significant. To this end we propose an internal axial sludge thickener.
