Title:
METHOD OF AND SYSTEM FOR FLUSHING CHLORINE-CONTAINING FINE PARTICLE
Document Type and Number:
Japanese Patent JP2021146249
Kind Code:
A
Abstract:
To provide a flushing method and flushing system for chlorine-containing fine particles for stably satisfying the control reference value of waste water in the discharge of cleaning water generating in the flushing desalination treatment of the above fine particles.SOLUTION: A flushing method for chlorine-containing fine particles comprises: a slurrying process of slurrying chlorine-containing fine particles by adding water; a first solid-liquid separation process of separating the slurry into a solid and a liquid to collect a discharge water after flushing as a liquid phase; a conditioner addition process of adding an oxidation-reduction potential conditioner to the above discharge water; a first coagulation process of forming a first coagulation slurry in which the oxidation-reduction potential is controlled within a specific range while adding a ferrous inorganic coagulant to the discharge water to which the above conditioner is added; a second coagulation process of adding a high molecular coagulant to the first coagulation slurry to form a second coagulation slurry; and a second solid-liquid separation process of separating the second coagulation slurry into a solid and a liquid to collect noble metals as a solid phase.SELECTED DRAWING: Figure 2
