In　order　to　guarantee　the　reliability　and　security　of　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　reuse　process　was　undergoing　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　21.01μg/L　for　Di-n-butyl　Phthalate　(DBP);　9.63μg/L　for　Di-n-octyl　Phthalate　(DnOP);　4.56μg/L　for　Diethyl　Phthalate　(DEP);　1.96μg/L　for　Dimethyl　Phthalate　(DMP)　respectively　in　the　influent.　The　conventional　activated　sludge　has　good　removal　efficiencies　performance　on　DMP,　DEP　and　DBP.　With　the　increasing　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　only　45.13%　removal　rate　for　DnOP,　which　was　mostly　removed　from　primary　treatment　but　no　from　secondary　activated　sludge　process;　Coagulation-air　flotation　plus　filtration　process　was　not　a　feasible　way　to　remove　PAEs　from　reclaiming　treatment　units.　©　(2013)　Trans　Tech　Publications,　Switzerland.
