| Abstract | ||
| The evaluation of the efficiency of the sewage treatment plant in Baghdad's Dora district Albueitha province, through the measurement of some of the physical, chemical and biological aspects of the waste water treatment plant. The samples were collected for five months on January 15, 2015 until May 15, 2015, and by half a monthly basis. Selected four locations for sampling from the treatment plant, the site first before sewage entry to the station (S1), the second location after the biological treatment basins (S2), the site after the third unit the final sedimentation (S3), the site the fourth after the final treatment phase(S4 ) results showed that the water discharged into the Tigris River from the treatment plant has been characterized rates degree water temperature (18.9 Co) pH (7.397) and biological oxygen demand (38.9 mg / l) within the permissible limits of the Iraqi standard specifications while the dissolved oxygen rate (0.808 mg / l) and the rate of electrical conductivity (1605 Micro Siemens / cm) below the limits required availability, and characterized this plant efficiently remove the values of turbidity (9.39 naphthalene turbidity unit), reaching removal efficiency for this specific (91.624%) . The rates of cadmium (0.0244 mg/L.) and lead concentration (0.1274 mg / L.) in drained waste water were within the allowed limits. The station capability to remove these metals reached (84.298%) and (61.970%) respectively. Also the presence of both Salmonella spp bacteria Shigella spp were noticed in the drained waste water .The study showed through statistical analysis of the factors examined in the station there were no significant differences between the study sites, while there are differences between the high moral months of the study. | ||
