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 (up to more than 99 percent), high organic matter content, easy decomposition and stink generation, fine particles, small specific gravity and colloidal liquid state. It is a thick matter between liquid and solid and can be transported by a pump, but it is difficult to perform solid-liquid separation by sedimentation. Sludge dewatering is an important link of the whole sludge treatment process, and aims to enrich solids, reduce sludge volume and create conditions for final treatment of sludge. The binding force between the liquid and solid phases of sludge must be overcome in order to separate them, so the main problem encountered in sludge dewatering is the energy problem. Aiming at different forms of the binding force, different external measures can be purposefully adopted to obtain different dehydration effects. The sludge dewatering and drying comprises natural dewatering, mechanical dewatering and heat treatment drying.
However, the water in the sludge contains both natural water which is easy to separate and bound water which is difficult to separate and exists in cells and bacterial colonies, the natural water can be separated in a mechanical dehydration mode, but the separation process of the bound water is more complicated, multiple treatment processes including heat treatment need to be comprehensively applied, and the whole process is high in energy consumption and cost.
The main problems of the existing sludge dewatering device in the actual use process include:

2. The existing sludge dewatering device usually adopts a standing sedimentation mode to carry out layered separation of sewage and sludge in the using process, the whole process is slow, the dewatering efficiency is low, and the time cost of sludge treatment is increased.
3. The existing sludge dewatering device can only separate sewage from sludge, the separated sewage needs to be introduced into other devices for retreatment, the operation process is complicated, and the continuity of the whole sludge dewatering and sewage treatment is damaged, so that inconvenience in the industrial production process is caused.
4. The existing sludge dewatering device is not provided with a sludge adding and discharging mechanism, so that the sludge is easy to accumulate in the device after dewatering and is difficult to discharge.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
