To improve the removal of phthalic acid ester (PAEs) from micro-polluted water, the activated carbon was used as an adsorbent in an experiment which focused on activated carbon selection and carbon column adsorption of PAEs. The results showed that the adsorption behavior of three activated carbons, namely charcoal, coal charcoal, and shell charcoal, was consistent with the Freundlich empirical model. When the dose of shell charcoal was 8 g/L, the removal rate of dibutyl phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP) reached 100%, and the adsorption capacity on dimethyl dicarbonate (DMP) and diethyl phthalate (DEP) was 14.712 μg/g and 5.143 μg/g, respectively, which were higher than the corresponding removal rates of coal charcoal and charcoal. The removal rates of shell charcoal on the four PAEs were more than 85%, and the equilibrium concentrations were less than 0.5μg/L. The carbon column adsorption experiment was performed with the PAEs influent concentration of 5-20 μg/L. The removal efficiency of PAEs by the advanced treatment of activated carbon met the Standard for Drinking Water Quality (GB 5749-2006), and was superior to the conventional water treatment process in terms of removal efficiency and adsorption stability.
