【 摘 要 】
The present study was to reflect the use of some bacteria in the treatment and removal of pollutants in three selected wastewater sites, including a vegetable oil plant (viz. Al-Etihad Food Industries), the main wastewater treatment station in the city of Hila, and Al-Hila River water from October 2019 to January 2020. The bacterial isolates identified in these three sites were Klebsiella pneumoniae, Escherichia coli, Enterobacteria cloacae, Pseudomonas aeruginosa, Thalasobacillus devorans, Acinetobacter baumannii , and Bacillus subtilis . The molecular study of the bacterial isolates involved the detection of bacterial genera using the polymerase chain reaction (PCR). The results showed that water had a variable nature, depending on the substances in it. It recorded varying chemical and physical property values, ranging between 6.36 and 7.82 for pH and from 2500 to 7100 mg∙dm–3 for total alkalinity. Additional values were 713–2051 μS∙cm–1 for electrical conductivity (EC), 5.90–9.80 mg∙dm–3 for chemical oxygen demand (COD), and 480–960 mg∙dm–3 for total hardness. The given values were also 0.20–0.65 μg∙dm–3, 0.03-0.23 μg∙dm–3, and 0–107 mg∙dm–3 for nitrite (NO2), phosphate (PO4) oils, respectively.
