COAGULATION PROCESSING METHOD, COAGULATION PROCESSING UNIT, AND WATER PROCESSING APPARATUS

摘要

The present invention provides a coagulation processing method capable of adding a sufficiently-dissolved coagulant aqueous solution to being processed water and materializing high-efficiency coagulation processing, a coagulation processing unit, and a water processing apparatus.;A coagulation processing unit includes a coagulant aqueous solution storage tank 1 to have a stirrer 5 and store a coagulant aqueous solution, a particle size distribution measurement device 50 to measure the particle size distribution of the coagulant aqueous solution in the coagulant aqueous solution storage tank 1, a coagulation tank 11 to mix being processed water with an added coagulant aqueous solution and form a coagulation, a coagulation removing section 9 to remove the coagulation from the being processed water containing the coagulation, and a control section 6 to control the stirrer 5 so that a median size in the particle size distribution of the coagulant aqueous solution may be not more than 1.0 μm on the basis of a measured particle size distribution.
