Abstract:Removal efficiencies of organic micropollutants in wastewater-based reclaimed water by two water reclamation plants (WRPs) with different treatment processes in Beijing,China were investigated. Target compounds consisted of twenty kinds of micropollutants belonging to different groups. Besides, the estrogenicity of samples were evaluated by modified recombinant yeast estrogen screen (YES). The process of ozonation combined with ultrafiltration (UF) could be considerably effective to remove organic micropollutants from aqueous phase, and estradiol equivalent (EEQ) in the final effluent was not detected by YES assay. In addition, the process of reverse osmosis (RO) following anaerobic/anoxic/oxic and membrane bioreactor (MBR) showed such high removal efficiencies of target compounds that few of them could be detected in the final effluent. The results indicated that the two processes could alleviate the potential environmental risk caused by reclaimed water, and guarantee their safe and healthy reuse.
