The occurrence and fate of heavy metals, including Cd, Pb, Mn, Cu, Zn, Cr, Fe, Ni, Co, Ag and Ba were investigated in the West wastewater treatment plant of Handan, China. The samples were detected by ICP-MC. The target compounds were detected with the concentrations of 2.9μ g/L~1994.4μ g/L and 1.2μ g/L~1189.6μ g/L in the influent and secondary effluent, respectively. Most of the heavy metals were removed partly after treated by the biological wastewater treatment process. The removals of Cr, Cu, Zn, Ag, Pb were 53%~73% and the removals of Mn, Co, Cd, Ba were 26%~48%. But the removal of Ni was negative. The sludge contained for more heavy metals than influent, and Zn was the most abundant metals in the raw sewage and final sludge. It indicated that Zn and Cu were primarily (>;63%) accumulated in the sludge, while 48%~78~of Pb, Ba, Cr, Cd, Ag, Co and Mn remained in the treated effluent.
