摘　　要：江西某油墨生产企业采用活性炭吸附+Fenton氧化+混凝沉淀+三效蒸发对含苯酚废水进行预处理,对COD、色度、含盐量以及苯酚的去除率分别为72.48%、98.40%、99.00%、98.04%。之后采用UBF+A/O+接触氧化的组合工艺进一步处理混合废水,对COD、NH_(3)-N以及苯酚的去除率分别为98.24%、92.55%、98.60%,出水水质满足《油墨工业水污染物排放标准》(GB 25463-2010)中新建企业水污染物排放浓度限值要求。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/0 and contact oxidation is used to further remove the mixed wastewater.The removal efficiency of COD,NH_(3)-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 forPrinting Ink Industry(GB25463-2010).
