A natural aeration biofilter was employed to treat the secondary effluent.Results showed that a favorable aerobic condition could be created by the biofilter.And the biofilter showed good performance on removal of SS,COD and NH4+,with values of 76%,45% and 77%,respectively.Individual concentrations of phenolic endocrine disruptors(EDCs) in secondary effluent ranged from 1 to 1639 ng/L for biophenol A(BPA),4-nonylphenol(4-NP),4-t-octylphenol(4-t-OP),triclosan(TCS) and estrone(E1),whereas estradiol(E2) and ethinylestradiol(EE2) were not detected.Natural aeration biofilter could significantly reduce content of above micropollutants with removal efficiency of 49%,63%,78%,80%,and 46%,respectively.Furthermore,the effect of HLRs on the removal of EDCs was closely related to the hydrophobicity of chemicals.Removal rates of 4-NP,4-t-OP and TCS went up with decreasing HLRs,while that of BPA performed the opposite.Moreover,removal rate of E1represented no changes with varying HLRs.The main reason should be that the adsorption affinity of organics with weak hydrophobicity would be lessened by those with strong hydrophobicity.
