Behavior of Selected Endocrine Disrupting Chemicals in Sewage Treatment Plant

Abstract : The behavior of endocrine disrupting chemicals in sewage treatment plant affects their final fate in water environment. We selected six endocrine disrupting chemicals: 4 alkylphenols (4-tert-octylphenol, octylphenol, 4-nonylphenol, bisphenol A) and 2 steroids (17α-ethinylestradiol and estriol) as targets, their removal and transformation in wastewater treatment plant were studied. Five mixed liquors were sampled respectively from different stages of Minhang wastewater treatment plant in Shanghai. EDCs concentration were analyzed with GC-MS. The main removal pathways of EDCs include initial adsorption by suspended solids and following biodegradation in biological sludge. The removal efficiency of six targets was more than 86%. The concentration of OP and 4-n-NP in water significantly increased in anoxic stage, the reason may be the releases of EDCs from sludge to water on the condition of low DO. And it was also found that the EDCs could be released to water phase in the secondary clarifier, which may cause potential risk of EDCs entering the environment with discharge.
