A method and apparatus for treating wastewater containing a crystallization target component. |
| abstract |
[PROBLEMS] To crystallize without adding a crystallization agent and to reduce the concentration of components to be crystallized in waste water by crystallization treatment. A wastewater treatment method and apparatus that can be stably operated at a high concentration ratio without being provided. Waste water containing a crystallization target component is treated by a combination of distillation concentration treatment and crystallization treatment. A part of the concentrated waste water obtained by distillation concentration is taken out of the system, and the rest is introduced into the crystallization step for crystallization, and the crystallized product is taken out. By this combination treatment, the concentration of the components to be crystallized in the waste water flowing into the distillation concentrator can be reduced by the crystallization treatment, so that the concentration ratio of the distillation concentration can be increased and the crystals necessary for the crystallization treatment can be increased. A wastewater treatment method and apparatus capable of performing a crystallization treatment without adding a crystallization chemical by substituting a distillation concentrated liquid having a high concentration of the crystallization target component for the addition of the chemical for crystallization.
