Abstract
The Present study investigates the quality of liquid wastes that are directly or indirectly discharged in Tigris. The following hospitals in the city of Mosul are selected to be the test subjects: Hospitals group, Al- Salam General Hospital, Ibn Al Atheer for Pediatric Hospital and Al Khansaa Delivery Hospital. This is to periodically obtain the samples examine the chemical and bacteriological analysis according to the international standard methods. In addition to the bacteriological tests: Bacteria Total Number, Facal Eschereshia coli Number are tested, as well as, a number of the Pathogenic Bacterial Agents from the discharged wastes are identified after API system. The outcomes of this study indicate that the hospitals row discharged parameters have increased with the organic load values which reach 119.6 mg / L and the concentrations of DO are decreased to reach (0.0). This decrease has its negative effects which are as a result to creating anaerobic conditions, changing in the pathways and analysis of organic materials or their mechanisms. It was also found that the treatment station of Hospitals Collection and Al Salam General Hospital has been characterized by a high quality compared with other hospitals under investigation. The percentage of release BOD5 (91.8% and 97.6% ) respectively, the percentage aero bacteria release percentage (80.3% and 99.7% ) respectively, and E. coli release percentage (86.83% and 96.07% ) respectively. The following pathogenic Bacteria are isolated and characterized: Aeromonas hydrophila and E. coli with high percentages in sanitary release for all hospitals in addition to the following bacteria .
