Apparatus and method for mixing conditioning agent, in particular flocculant, in sludge

摘要

The invention relates to a device for mixing conditioning agents, in particular flocculants, into sludges, in particular biogenic sludges, udneten or can be arranged around a rotation axis (R) rotating or rotatable mixing rotor (1) - with the rotation axis (R) outwardly projecting interference (4), between which intermediate spaces (5) are formed, - wherein at least a part of the mixing elements (4) at least one, preferably each, adjacent gap in each case at least one mixing edge (41, 42, 43, 44), preferably at least two from each other spaced interference edges (41, 42, 43, 44), wherein each of these interference edges (41, 42, 43, 44) extends from the inside to the outside as seen from the axis of rotation, and a method for mixing in conditioning agent, in particular flocculant (F) into a sludge (S) using a device according to any one of the preceding claims and the mixing rotor (1) essentially completely, but at least with its mixing elements (4), with which the sludge is surrounded or submerged or submerged in the sludge, preferably the sludge-added conditioning agent, in particular flocculant, the separation of the liquid phase or liquid, especially water, from solids, including solid fractions of cells of organic origin contained in the sludge, which promotes or enhances the sludge and / or in which solid particles and / or solid cell constituents of the sludge and flocculant are formed into flocculates of various sizes and liquid, especially water, of the sludge is released.
