| titleOfInvention | A method and system for treating and recycling cotton dyeing waste dye liquor |
| abstract | The invention discloses a method for treating and reusing cotton dyeing waste dyeing liquid, which uses electrocoagulation to capture and oxidatively decomposes to completely decolorize the waste dyeing liquid to obtain recovered brine, and further utilizes a concentrating device to distill and concentrate the recovered brine to obtain brine that meets the technological requirements. Saline concentration and distilled water are used in the back dyeing process. According to the treatment requirements of waste dyeing liquid, carry out electrocoagulation, air flotation flocculation, neutralization coagulation, static sedimentation, filtration to remove slag, oxidation decolorization, filtration separation, concentrated distillation procedures to obtain brine that meets the requirements of the dyeing process. Concentration and distilled water are used in the dyeing process, so that the salt content in the waste water is not destroyed, and can be used in the dyeing process, so that the salt and water in the waste dyeing liquid treatment are not discharged, but can be recycled. |
