| titleOfInvention | Waste liquid treatment method |
| abstract | (57) [Summary] [Structure] A method of heating and concentrating a waste liquid containing a component that produces a scale in a volume-reducing operation process by heating, in which the temperature of the evaporating liquid is 90 ° C or higher, and anhydrous gypsum is seeded. The method is characterized in that at least the evaporation unit is washed with water at regular intervals. [Effect] According to the present invention, waste liquid treatment is performed by one unit operation of heating / concentration, and sludge that is difficult to dispose is not discharged (in principle, it should be a mineral-like substance or a useful substance). Since the recovery is performed), it is possible to provide the waste liquid treatment that meets the demands of the era of economical and no drainage. |
