Abstract: |
Coking wastewater from the process of coking, coal gas purification and the coking products refine, whose ingredients are complicated and inconstant, is hard to meet the standard of reclaimed water used for industrial water by secondary treatment. In view of this situation, the advanced treatment technique of coking wastewater was desired. The innovatory flocculation treatment was used to regenerate coking wastewater with the help of surfactant (the number of the Chinese patent is: CN200910063253.2). The synergistic effects of the surfactant (named K) could improve the traditional flocculation treatment process. The results showed that in the combination of IPF(Inorganic polymer flocculants)+OPF(Organic polymer flocculants) + Surfactant(K), surfactant (K) can incur obvious synergistic effects within the flocculants system. The COD and chromaticity less than 50mg/l and 30° respectively under the optimum condition, the water quality of the treatment of coking industrial wastewater can meet the water quality standard for industrial uses. So this synergistic treatment technology by fine chemicals and flocculants can be effective for industrial wastewater regeneration.
