| titleOfInvention | ECF bleaching process wastewater treatment method |
| abstract | An object of the present invention is to efficiently treat organic components and colored components in wastewater from an ECF bleaching process in a paper pulp manufacturing process by a collection and precipitation process. [Solving Means] First, slaked lime is added to acid wastewater and alkaline wastewater mixed with bleaching without using elemental chlorine (ECF), and then ferrous chloride solution is added, and then the pH is adjusted to 8-12. A method for treating ECF bleaching process wastewater that is adjusted and cuts chromaticity by 50% or more. The wastewater contains chlorine dioxide bleaching stage wastewater, and the slaked lime is added in a range of 200 to 450 ppm. [Selection figure] None |
