Background

In the sludge dewatering process, before sludge is dewatered, a flocculating agent is required to be added into the sludge for flocculation so as to facilitate the dewatering operation, and the flocculation process can be understood as follows: the flocculant is mixed with the sludge, and suspended (colloidal) matters in the sludge are agglomerated under the action of the flocculant, so that the aim of separating the sludge from the water is fulfilled. In the flocculation, the uniform mixing state between the slurry and the flocculating agent is kept, and the uniform distribution of the preliminarily formed flocculating constituents in the slurry is also kept, so that the flocculating constituents grow uniformly and quickly, and the fine flocculating constituents are polymerized into large flocculating constituents, thereby improving the flocculation effect. This requires a stirring operation to provide the mixing and agglomeration conditions required for the flocculation process.

Because density is different, silt is easily depositd in the agitator tank bottom, therefore the silt of co-altitude is different with the mixed degree of flocculating agent, the too high position that the stirring rake set up in the agitator tank can lead to sedimentary silt can't mix with the flocculating agent, the position that the stirring rake set up in the agitator tank is in the agitator tank bottom, though can stir the silt of bottom, nevertheless it is longer with the time that the flocculating agent intensive mixing needs to make, and stirring speed is big, can cause the destruction to the flocculating agent, the even degree of mixture also can't be guaranteed.
