摘要：

The research employed the adsorption isotherm measurement,the batch kinetic adsorption and the rapid small-scale carbon column test(RSSCT)to find out the characteristics and main impacting factors of granular activated carbon(GAC)adsorption,in treating the textile dyeing-printing/polyester alkali de-weighting secondary effluent(TSE).The adsorption affinities and capacities for the organics surrogated by CODCr,color and UV254(UV absorbency at λ=254 nm)predicted by isotherm,small-scale-fixed bed were discussed.Adsorption rates for CODCr,color and UV254 are much different and carbon particle size dependent.The color adsorption rate and capacity should be taken as the main consideration factors in designing bio-activated carbon filter(BACF).The breakthrough of GAC adsorption column is mainly influenced by the low MW readily adsorbable organics in TSE.UV254 is a good adsorption breakthrough indicator.The study provides references for BACFs’ design and operation control in textile secondary effluent(TSE)tertiary treatment.
