The study on removal regularity for NP and BPA in oxidation ditch wastewater treatment process

The methods of solid phase extraction (SPE)-high performance liquid chromatography (HPLC) for the determination of target EDCs in sewage were established in this research firstly. In this way, the concentrations of target EDCs in the second sewage treatment plant in Huainan were investigated in sewage during sewage treatment process in detail. Results show that during the whole process, the total removal rates of NP and BPA are 67.3% and 79.5%, and the removal rates of NP and BPA during the process of oxidation ditch are 25.3% and 44.9%, The process of existing oxidation ditch wastewater treatment can not completely remove NP and BPA.
