Removal Efficiency of Environmental Endocrine Disrupting Chemicals Pollutants--Phthalate Esters in Northern WWTP
In order to guarantee the reliability and security of the reclaiming water,research on the removal efficiency of the environmental endocrine chemicals (EDCs) —the Phthalate Esters (PAEs) in conventional secondary activated sludge and wastewater reclamation and the reuse process was under way at Harbin wastewater treatment plant (WWTP).The wastewater samples were colleted from every unit effluent of WWTP.The results showed that contamination of EDCs were presented in municipal wastewater at Harbin and the concentrations of the four PAEs were 21.01 μg/L for Di-n-butyl Phthalate (DBP) ; 9.63 μg/L for Di-n-octyl Phthalate (DnOP) ; 4.56 μg/L for Diethyl Phthalate (DEP) ; 1.96 μg/L for Dimethyl Phthalate (DMP) respectively in the influent.The conventional activated sludge has good removal efficiency performance on DMP,DEP and DBP.With the increase of molecular weight and branch chains of PAEs contaminations,the removal rate of the four PAEs in the conventional activated sludge process decreased from 99.82% (DMP),90.60% (DEP),90.10% (DBP) to the mere 45.13% removal rate for DnOP,which was mostly removed from the primary treatment but not from secondary activated sludge process ; Coagulation-air flotation plus filtration process were not a feasible way to remove PAEs from reclaiming treatment units.
