Abstract:
For a printing ink manufacturer in Jiangxi Province, the process of activated carbon adsorption, Fenton oxidation, coagulation precipitation, three-effect evaporation is used to pretreat phenol-containing wastewater. The removal efficiency of COD, chroma, salt content and phenol reached 72.48%, 98.40%, 99.00%, and 98.04%, respectively. Afterwards, the combined process of UBF, A/O and contact oxidation is used to further remove the mixed wastewater. The removal efficiency of COD, NH3-N and phenol reached 98.24%, 92.55%, and 98.60%, respectively. The effluent water quality indexes meet the water pollutant discharge concentration limit of newly-built enterprises in the Discharge Standard of Water Pollutants for Printing Ink Industry (GB 25463-2010).
