Abstract

To study Ideal physical and chemical evaluation of treatment wastewater. wastewater samples were collected (one sample per week) by taking samples at the beginning of January 2012 along one year, from collection station of wastewater in Al-Naimea region-Fallujah/Anbar governorate. American Environmental Protection Agency (1977, EPA) method was used to determine the characteristics of wastewater including measuring and estimating of pH, EC, BOD, COD, Ammonium, Nitrate, Total phosphate, Soluble cations and anions as well as determining the Total heavy metals contents (e.g. Fe, Cu, Zn, Cd, Pb, Ni, and Mn), also the physical characteristics which includes [Total Dissolved Solids (TDS), Total Suspended Solids (TSS)] were also determined., on average 3114 ,149 mg .L-1 for all TDS and TSS sequentially. It is value suitable to use in agriculture. Concentration of negative and positive anions of wastewater was highest as compared with river on ions (SO4 -2 , Cl- , K+ , Na+ , Mg+2,Ca+2) on average (790, 380, 24.2, 524.4, 138.3, 283.1) mg.L-1 respectively. As well as content of wastewater on ions environment dangerous such Ammonium, Nitrate, phosphate, it was highest of minimum to drop in river , on average 6.2 , 21.2 ,15.0 mg.L-1 for all (NH4 ,NO3 , P) respectively. increased about 222, 00.2, 32.2% of minimum to drop in river. Ammonium ions sovereignty on Nitrate.
