Abstract

The treatment of the industrial wastewater discharged from naphthol AS production by adsorption with NDA - 222 resin has been studied. The efficiency o n adsorption - desorption is excellent. After the treatment of acidification and adsorption, the TOC concentration in the wastewater is decreased from 15 500 mg /L to less than 20 mg/L, which is transparent and decolored, meeting the nationa l standard. A lot of 2,3 - acid and naphthol AS can be recovered by acidificatio n of the raw wastewater and desorptive solutions. According to its perfect effic iency, short process, simple operation, economic and environmental benefits, thi s technology is prospectively applied in the treatment of industrial wastewater of naphthol dyes.
