摘要： A polymer flocculant mixing and dissolving system comprising: a mixing tank (2) in which a solid polymer flocculant is mixed with water used as a solvent; a liquid feed unit (3) for feeding an aqueous solution containing the polymer flocculant from the mixing tank; a regenerative mixer (4A,4B) used to mix and dissolve the polymer flocculant by applying pressure to the aqueous solution containing the polymer flocculant fed from the liquid feed unit while forming a vortex flow; a process channel (61) through which the aqueous solution that has passed through the regenerative mixer is fed to a downstream process; a circulation channel (62) through which the aqueous solution is returned to a position on an upstream side of the liquid feed unit; and a flow rate adjusting unit (6) for adjusting a balance between a flow rate of the aqueous solution flowing through the process channel and a flow rate of the aqueous solution flowing through the circulation channel. The polymer flocculant mixing and dissolving system can stably supply the solution in an amount required in the downstream process.

摘要： Disclosed is a sludge processing system having a centrifugal separator concentrating the sludge and a furnace heat-treating the concentrated sludge. It allows automatic control in which the operational condition of the centrifugal separator operates under optimal conditions according to the operational state of the furnace. The control device sets a variable range of a differential speed between the bowl and screw conveyor of the centrifugal separator, and variably controls the differential speed so concentrated sludge convey torque of the screw conveyor achieves a torque corresponding to a moisture content requested by the furnace within the variable range, when the differential speed varies within a certain previously set range and the concentrated sludge convey torque of the screw conveyor maintains the torque corresponding to the moisture content requested by the furnace for a certain period of time being previously set, changes a control value of the centrifugal force and the torque.
