摘要

•A multi-objective target was obtained by Fe(II)/PAA coupling UF for secondary effluent treatment.•Fe(II)/PAA could reduce UF fouling resistance by 90.2%.•BOD5 content and C/N ratio of UF permeate was greatly improved.•Fe(II)/PAA could effectively remove phosphorus by the in-situ generated Fe(Ⅲ).
